Also, the present invention relates to a powdering agent comprising such high-activity calcium oxide. The present invention also relates to a powdery blood product that contains the blood that may be collected in large quantities from animals killed or butchered for food in the slaughter house and is processed in such a manner that the product can retain the major part of the useful components such as nutrients originally contained in the raw blood without affecting or altering the quality of the useful components using the before mentioned high-activity calcium oxide. The present invention also relates to a method of manufacturing such powdery blood products. The present invention further relates to a powdery oil product which is produced from any liquid oils such as animal oils, vegetable oils and mineral oils using the before mentioned high-activity calcium oxide. The present invention further relates to a method of manufacturing such powdery oil product. Background Art It is known to the art that a calcium oxide may be obtained by processing shells such as seashells at the particular high baking temperatures. Usually, the calcium oxide may be obtained by baking those shells at 900 "C to lOOO'C. For the calcium oxide obtained in the conventional manner by baking the shells at the high temperatures, it is reported that its activity may potentially be improved, but what the activity could be improved has not been determined yet 26 1 9 It is a!so known that by adding water to unslaked lime (calcium oxide), it turns into slaked lime (calcium hydroxide). If more water is added, the unslaked lime is formed like a sludge, and if less water is added, it is formed into gross powders having irregular sizes. Fine powders of uniform sizes cannot be obtained. There are various conventional processing methods that have been proposed for processing the blood from the animals killed or butchered in the slaughter facilities. Some of those processing methods are specifically intended for processing the blood into a powdery form, and use the adsorption dehydration process or vacuum dehydration process. Any of those conventional animal blood processing methods requires the use of the large-scale, complicated equipment for processing the blood into a powdery form, and those methods are not economical from the aspects of calorie, cost, labor and time consumption. If any blood from the killed animals is left unprocessed for any extended period of time, it will corrupt and alter, producing the disagreeable odor. Those corrupted or altered bloods are often thrown into rivers or the like for disposal, causing the environmental pollution. It is known that the raw blood that has been collected from any killed animal contains a variety of useful or nutritious substances. In addition to the problems described above, the conventional methods have another problem in this regard. According to those conventional methods, those useful components are destroyed during the process, and cannot be made any effective use. There is also a conventional method of producing a powdery oil product from any particular liquid oil. According to the conventional method, liquid oil is added to a particular powdery substance and is allowed to be absorbed by the powdery substance. The product thus obtained contains the oil component formed into powders. The powdery oil product that has thus been obtained simply by allowing the liquid oil to be absorbed by the powdery substance retains its own property (oiliness) which makes the oil powder particles sticky. Because of its sticky nature, the oil powder particles may easily be conglomerated, or formed into gross solids, when they are packed into a package. This may cause a problem in handling, such as when using or weighing the powders. For example, consider that more than 10 % by weight of a particular liquid oil is added to a powdery calcium oxide and is allowed to be absorbed by the powdery calcium oxide. Then, the oil poweder particles that result from the above process remains so sticky that they may easily be formed into gross solids when they are packaged. When any liquid oil is only added to the powdery calcium oxide, they can not react chemically to each other. Rather, the liquid oil is simply absorbed by the powdery 26 10 calcium oxide. As such, the resulting powdery oil product can contain powder particles that retain the oily property that disadvantageous^ makes them sticky. In most cases, it is difficult to provide the uniform mixture of the liquid oil and any particular powdery substance. Disclosure of Invention In the first aspect, the present invention provides a high-activity calcium oxide that may be obtained by baking eggshells at the particular temperature range of between 900*0 and 1500 *0. In the second aspect, the present invention provides a high-activity calcium oxide that may be obtained by baking eggshells at the particular temperature range of between 1200*O and 1300*0. In the third aspect, the present invention provides a powdering agent comprising a high-activity calcium oxide, wherein said high-activity calcium oxide is obtained by baking eggshells at the temperature range of 900*C and 1500*C. In the fourth aspect, the present invention provides a powdering agent comprising a high-activity calcium oxide, wherein said high-activity calcium oxide is obtained by baking eggshells at the temperature range of 1200*0 and 1300*0. In each described case, the high-activity calcium oxide according to the present invention differs from the calcium oxide according to the prior art in that when the former is mixed with any moisture-contained substance in an almost equal mixture ratio by weight, it will react quickly, and can be formed into fine powders without losing any resolvable components in the moisture-contained substance and without affecting or altering the properties of those resolvable components. Also, the powdering agent comprising said high-activity calcium oxide according to the present invention can react quickly with any moisture-contained substance, when the powdering agent is mixed with any moisture-contained substance in an almost equal mixture ratio by weight, and can be formed into fine powders without losing any resolvable components in the moisture-contained substance and without affecting or altering the properties of those resolvable components. In the preceding description, it is noted that the moisture-contained substance may be any substance that contains an aqueous solution or water. Other substances that does not contain a water, for example oils, also can be formed into powders if they are mixed with a water, and then added the high-activity calcium oxide. The term "moisture-contained 26 1 9 substances" referred to herein should be understood to include an aqueous mixture of such other substances that does not contain a water. At any baking temperature below 900*0, the produced calcium oxide provides a low activity. Thus, when it is mixed with the moisture-contained substance, the latter is easily formed like a sludge, which prevents the calcium oxide from being formed into fine powders. At any baking temperature above 900*0, the produced high-activity calcium oxide provides a high activity. Thus, when it is mixed with the moisture- contained substance in the almost equal mixiture ratio by weight, it will react quickly, and can be formed into fine powders without losing any resolvable components in the moisture-contained substance and without affecting or altering the properties of those resolvable components. At any baking temperature below 1000*O, the produced high-activity calcium oxide also provides a high activity. However, when it is mixed with the moisture-contained substance, it will react relatively slowly. At any baking temperature above 1000*C, the produced high-activity calcium oxide also provides a high activity. When it is mixed with the moisture-contained substance, it will react relatively quickly compared with the reaction rate which may be obtained by the high-activity calcium oxide produced by at any baking temperature below 1000O. The reaction rate at which the moisture-contained substance is formed into fine powders under the reaction of the high-activity calcium oxide becomes fast little by little according to the ascent of the baking temperature from 1000O. At the baking temperature of 1500*C, the produced high-activity calcium oxide provides a high activity which can show the same reaction rate as the reaction rate provided by the high-activity calcium oxide which is obtained by the baking temperature at 1300°C. It may be understood from the above fact that the preferred baking temperature range should be between 900O and 1500O, and the high-activity calcium oxide can then be obtained at any temperature within the temperature range as specified above. It should be noted that since the reaction rate which is obtained by the high-activity calcium oxide produced at the baking temperature of 1500O is substantially the same as that is obtained by the high-activity calcium oxide produced at the baking temperature of 1300O, the upper temperature limit may preferably be set to 1300O in terms of the better efficiency and the better cost effectiveness. Raising the baking temperature beginning with 900°C produces each correponding high-activity calcium oxide that reacts at a higher rate. The experiments 26 1 9 conducted by the inventor demonstrate that the lower temperature limit may preferably be set to 1200°C, considering the reaction rate that can be achieved when the different high-activity calcium oxides are mixed with the particular mositure-contained substance. The inventor of the application conducted the series of the experiments regarding to the preferred baking temperature ranges. The high-activity calcium oxides of the invention which are produced at the specific baking temperature range between 1200*0 and 1300*0 provide a stable high activity which can form the moisture-contained substances into fine powders, as compared with the another high-activity calcium oxides of the invention produced at the another baking temperature ranges. There are some high-activity calcium oxides of the invention which provide unstable high activity as time goes from the production of them. For example, however, the high-activity calcium oxides of the invention can provide the high activity which can form the moisture-contained substances into fine powders even if long time has past since the productions of them, there are some high-activity calcium oxides which provide relatively slow reaction rate when they are used long time after the productions of them than the reaction rate which they can provide if they are used near after the productions. The high-activity calcium oxides which are produced at the baking temperature range between 1200*0 and 1300*C can provide the relatively stable reaction rate at which the moisture-contained substances are formed into fine powders at any time, even if they are used long time after the productions of them, as compared with the another ones produced at the another baking temperature ranges. The high-activity calcium oxides which are produced at the specific baking temperature range between 1200O and 1300O can provide the superior stability of the reaction rate, as compared with the another ones. The high-activity calcium oxide that is obtained at the above temperature range and the powdering agent comprising such high-activity calcium oxide react quickly when water is added to it, and is formed into fine powders. Those powders may be formed by adding pure water, but acid water (such as wood vinegar liquid) may be added, in which case the reaction can occur more rapidly. Thus, the high-activity calcium oxide and the powdering agent comprising such high-activity calcium are very effective when forming the viscous liquid like blood, or liquid oils such as animal fats, vegetable oils or fats, or mineral oils into fine powders. Those fine powders can be obtained without losing any resolvable components contained in the moisture-contained substances and without affecting or altering their 2619 04 original properties. The present invention provides advantages, particularly when it is used for those liquid substances or moisture-contained substances that are difficult to be formed into fine powders. In this case, the powders can retain the useful components originally contained in those liquid substances or moisture-contained substances. When the reaction occurs, it produces its heat under which the fine powders may be obtained without any additional drying or other process. The high-activity calcium oxide or the powdering agent comprising such high-activity calcium oxide according to the present invention and the moisture-contained substance which is added to them should preferably have the almost equal mixture ratio by weight because this mixture ratio provides the fine powders resulting from the reaction that can best retain all of the useful components originally contained in the moisture-contained substance. The inventor of the application conducted the series of the experimentsin this regard, and obtained the following results. 0.3 to 3.3 parts by weight of any moisutre-contained substance was added to one part by weight of the high-activity calcium oxide according to the present invention or the powdering agent comprising such high-activity calcium oxide, and those were mixed together. The reaction occurred, producing the fine powders. The results show that different types of moisture-contained substances that are added produce different reactions that produce fine powders. For example, when a particular blood was used as the mositure-contained substance, the reaction occurred by adding 0.6 to 3.3 parts by weight of the blood to one part by weight of the high-activity calcium oxide or the powdering agent comprising such high-activity calcium oxide. For liquid oils, the reaction occurred by adding 0.3 to 1.7 parts by weight of a particular liquid oil to one part by weight of the high-activity calcium oxide or the powdering agent comprising such high-activity calcium oxide. The fifth and sixth inventions of the present application provide a powdery blood product that contains powders formed from a mixture of an animal blood and a high-activity calcium oxide by causing those components to react with each other, and a method of manufacturing such a powdery blood product. The said method includes placing a specific quantity of the animal blood and a specific quantity of the high-activity calcium oxide in a reactor container, stirring and mixing them together, and thereby causing them to react with each other so that they can be formed into fine powders. In this method, the animal blood and high-activity calcium oxide may have the mixture ratio by weight of between 1:0.5 to 1.5, or between 1:0.7 to 1.2. The high-activity calcium oxide may be obtained by baking egg 26 1 90 OT or shells at the particular baking temperature range, i.e., between 900O and 15001 between 1200O and 1300*0. The seventh and eighth inventions of the present application provide a powdery blood product that contains powders formed from a mixture of an animal blood, a high-activity calcium oxide and any organic acid or organic acid salt, and a method of manufacturing such a powdery blood product. The said method includes placing a specific quantity of the animal blood, a specific quantity of the high-activity calcium oxide and a specific quantity of any other organic acid or organic acid salt in a reactor container, stirring and mixing them together, and thereby causing them to react with each other so that they can be formed into fine powders. In this method, the animal blood and high-activity calcium oxide may have the mixture ratio by weight of between 1:0.3 to 1.5, or between 1:0.5 to 1.2. The high- activity calcium oxide may be obtained by baking egg shells at the particular baking temperature range, i.e., between 900°C and 15000 or between 1200*0 and 1300O. The organic acid may be selected from the group consisting of propionic acid, formic acid, malic acid, lactic acid, and the like, and the organic acid salt may be selected from the group consisting of calcium propionate/ sodium propionate, sodium sorbate, ammonium propionate, ammonium formate, and the like. According to the method, the animal blood and the high-activity calcium oxide may be provided or the animal blood, the high-activity calcium oxide and any organic acid or organic acid salt may be provided, and may be allowed to react against each other sufficiently until the resulting product can exibit the soft state containing voids. This reaction product can be formed into powders by simply crashing or milling it. Those powders may have the mesh sizes of 100. In the typical preferred embodiment of the present invention, the high-activity calcium oxide may be obtained by baking egg shells at the temperature range of between 900O and 1500O or between 1200°C and 1300O. Alternatively, sea shells or anything else that is readily available and contains pure calcium may be used by baking at high temperature range. It is noted that at the baking temperature above at least 900O, the sufficient reaction will not be provided. As described previously, the powdery blood product according to the present invention may only be composed of a mixture of an animal blood and a high-activity calcium oxide. In this case, the mixture ratio of those two components that causes the .reaction between the two f^^jOFFiCE] " 7 " I 20 JIJM 1996 26 19 should preferably be such that 0.5 to 1.5 part by weight of the high-activity calcium oxide is supplied for one part by weight of the animal blood. The reaction that occurs within this ratio range can produce powders from the two components. If the proportion of the high-activity calcium oxide is less than the values as specified above, the reaction will never occur even though a long time, e.g., 24 hours, elapses after the mixing process is completed. If the proportion of the high-activity calcium oxide exceeds the above value, on the other hand, there is no noticeable difference in each respective rate of the reaction corresponding to each value exceeding the above value. As it is clear from the above, the upper limit of the mixture ratio range may preferably be set to 1:1.5 by weight, which is economical. The experiments conducted by the inventor of the current application demonstrate that when the propotion of the high-activity calcium oxide ranges between 0.7 and 1.2 part by weight in relation to one part by weight of the animal blood, and when they are mixed together for causing the reaction, the best results may be obtained for the reaction rate, reaction time, and the quality of the resulting product. It may be determined from the data obtained through the experiments that the optimal mixture ratio of the animal blood and high-activity calcium oxide can be such that 0.7 to 1.2 part by weight of the high-activity calcium oxide is supplied for one part by weight of the animal blood, when the mixture composed only of the animal blood and high-activity calcium oxide is used to cause the reaction between the two components. When a powdery blood product is composed of an animal blood, a high-activity calcium oxide, and any organic acid or organic acid salt, and the reaction is caused among those three different components, the preferred mixture ratio of the animal blood and high-activity calcium oxide should be such that 0.3 to 1.5 part by weight of the high-activity calcium oxide is supplied for one part by weight of the animal blood. The reaction that occurs within this ratio range can produce powders from the three components. If the proportion of the high-activity calcium oxide is less than the values as specified above, the reaction will never occur even though a long time, e.g., 24 hours, elapses after the mixing process is completed. If the proportion of the high-activity calcium oxide exceeds the above value, on the other hand, there is no noticeable difference in each respective rate of the reaction corresponding to each value exceeding the above value. As it is clear from the above, the upper limit of the mixture ratio range may preferably be set to 1:1.5 by weight, which is economical. If it is desired that the reaction be completed in a relatively short time following the mixing process, thereby producing the powders, the proportion of the high-activity calcium oxide may 2 6 19 0 4 preferably be equal to more than 0.5 part by weight for one part by weight of the animal blood. As in the preceding case, the economical mixture ratio should preferably be such that 0.7 to 1.2 part, by weight of the high-activity calcium oxide is suppled for one part by weight of the animal blood, since this also provides the best reaction rate, reaction time and product quality. When any organic acid or organic acid salt is added to the combination of the animal blood and high-activity calcium oxide, and is made to participate in the reaction that occurs among those components, the proportion of the high-activity calcium oxide can be reduced as compared with the case where no organic acid or organic acid salt is added. This reduction may be achieved because the high-activity calciura oxide is alkaline while any origanic acid or organic acid salt is acidic. Any organic components that contain acid may be used and added to the combination of the animal blood and high-activity calcium oxide. Among others, any organic acid or organic acid salt is preferred. There is no limitation for organic acid or organic acid salt to be added. The final product that contains the powders formed from the components described above may be usued as feeds or fertilizers. The particular type of organic acid or organic acid salt to be added may be selected^ depending upon the particular usage of the final product. For example, when the final product is to be used as feeds for animals, any type of organic acid or organic acid salt designated as the proper additive to the feeds may be added. In this case, those organic acids may include propionic acid, formic acid, malic acid, lactic acid and the like. The organic acid salts may include propionic acid calcium, propionic acid sodium, sorbic acid sodium, propionic acid ammonium, formic acid ammonium, and the like. The proportion of any selected organic acid or organic acid salt may be equal to more than 0.1 part by weight rek ive to the total weight of the combination of the animal blood and high-activity calcium oxide. The stirring process that occurs when the animal blood and high-activity calcium oxide are to be mixed together in the reactor container may be omitted or bypassed. When the stirring process is involved, it should preferably occur slowly so that a uniform mixture of them can be obtained. The animal blood and the high-activity calcium oxide are added and mixed together, or the animal blood, the high-activity calcium oxide and any organic acid or organic acid salt are added and mixed together, and they begin to provide the exothermic reaction rapidly in 26 19 0 4 several minutes or several ten minutes. After this time, they results in a reaction product that is soft and cotains voids. This resultant product can readily be formed into powders by simply crashig it without involving any external drying process. Then, the powders may pass through the self-cooling, weighing and packaging processes. A final product may be delivered as a commercial powdery blood article. It should be noted that the reaction time may depend upon the ambient temperature, and may vary in a few hours between summer and winter. Through those processes, the final powdery product can retain the major part of the useful components that are originally contained in the raw animal blood and whose respective original properties are not affected, such as alterations. As described previously, all of the conventional methods have attempted to address the problem of how to effectively utilize the blood from the animals killed for food in the slaughter house, but those efforts have been unsuccessful. The blood has been disposed of uselessly. In contrast, the present invention allows the raw blood to be processed in large quantities. The raw blood thus processed can retain the various kinds of nutrients originally contained therein. The raw blood containing those nutrients as unaltered can then be formed into fine powders, which may be used as feeds or fertilizers for animals or plants, respectively. The method according to the present invention allows large quantities of blood to be processed so that the blood can be formed into powderes easily and rapidly, and provides the remarkable processing efficiency for the blood. During the blood processing, there is no risk of producing any secondary or accompanying environmental pollution (such as the disagreeable odor). The product obtained by the present invention has the powdery form which can be stored for any extended period of time without being altered or corrupted. The granulation or any other processing can be perfomed easily. Through the usual dehydration process, it is almost impossible or difficult to dry the blood into the powdery forms. According to the present invention, it is possible to process the blood into the powdery forms easily and without using any complicated equipment and without consuming a large amount of heating energy. During the powder forming process according to the present invention, the blood and the high-activity calcium oxide react readily against each other, or the blood, the high-activity calcium oxide and any organic acid or organic acid salt react readily against each other, producing the reaction heat As no external heating source such as the heater is required, the blood can retain virtually all of its original useful components as unaltered. The raw blood that has just been collected from any killed animal and is yet to be processed contains useful elements such as calcium, iron, various vitamins, and other nutrients. The present invention may be used for processing the raw blood before the coagulation of it, and those useful elements contained in the raw blood can have their respective properties remaining unaltered throughout the process. Those properties can be stabilized by keeping the blood in its powdery forms. Thus, the components contained in the final powdery product can be kept unaltered when it is stored in the usual manner. The final powdery product may be used effectively as feeds or fertilizers for animals or plants, respectively. In accordance with the method of the present invention, as a prelim-inary step, any useful crude drug or wood vinegar in a liquid form may be added at the proportion of 5% to 10% to the raw animal blood that contains no high-activity calcium oxide with which it reacts. Then, they may be mixed together, and the resulting mixture may be mixed with the high-activity calcium oxide, causing the reaction to occur between them. The powders that result from the reaction may be used as animal feeds or plant fertilizers that enhance the utilization of the blood components. The blood powders thus obtained in accordance with the present invention may be mixed with any activator. The mixing can be made readily. The present invention provides a convenient means of using the blood powders. For instance, the blood powders according to the present invention may be mixed with any other medicinal drugs (e.g., powdery wood vinegar), and the resultant mixture may be used as a nutrient for humans or animals, or as an activator for plants. The ninth and tenth inventions of the present application provide a powdery oil product that comprises any particular liquid oil component, a particular high-activity calcium oxide component and water or wood vinegar liquid component and which may be obtained by allowing those components to react to each other, and a method of manufacturing such a powdery oil product, respectively. In either case, a powdery oil product may be obtained by adding any liquid oil component to ether components including high-activity calcium oxide obtained by the invention described above and water or wood vinegar liquid, mixing those components together and allowing them to react. In a specific example,the components may include one part by weight of liquid oil, 0.6 to 3.0 parts by weight of high-activity calcium oxide, and 0.1 to 1.0 part by weight of water or wood vinegar liquid. The high-activity calcium oxide may be obtained by baking egg shells at the temperature range of between 900°C and 1500°C or between 1200 °C and 1300 °C. Liquid oils may include animal oils, vegetable oils and mineral oils. 2£ 1 9 0 In the prior art method, as described earlier, any particular liquid oil is added to powdery calcium oxide. Adding the liquid oil component to the powdery calcium oxide component simply allows the liquid oil component to be absorbed by the powdery calcium oxide component, without causing any chemical reaction between the two components. Thus, the powdery oil product contains the oil powder particles that retain the oily property which makes the oil powder particles sticky. In contrast and according to the method of the present invention, the particular powdery high-activity calcium oxide component that may also be provided by the present invention is used,wherein a liquid oil component may be added to the high-activity calcium oxide component and the powdery oil product thus obtained can contain non-sticky oil powder particles. The chemical reaction can be caused simply by mixing a liquid oil component, a powdery high-activity calcium oxide component, and any one of water or wood vinegar liquid component together, without requiring any positive processes, such as mixing,heating and others, that were required in the prior art method. In the specific composition ratio example shown above, if the water or wood vinegar liquid component is less than 10 % by weight relative to the oil component, the resulting product would become like clay (sticky state), rather than powdery. When the water or wood vinegar liquid component is more than 100 % by weight relative to the oil component, the resulting product would also become like clay (sticky state), rather than powedery. In either case, the resulting products are not desirable. In the above component ratio example, it is found that the proportion of high-activity calcium oxide component should be more than 60 % by weight in relation to that of oil component. If it is less than the above value, no desirable reaction can occur. The experiment results show that the desired reaction can occur so that powders can be produced even if the quantity of high-activity calcium oxide component is mare than the sum of the quantity of oil component and the quantity of water or wood vinegar liquid more than 10 % by weight relative to oil component, provided that the quantity of water or wood vinegar liquid component according to that quantity of high-activity calcium oxide component is added. When high-activity calcium component and water or wood vinegar liquid component are provided in adequate quantities., or more specifically, when the proportions of those components have the ratio of 1 : 1, for example, the desired reaction can occur with no particular limitations so that powders can be produced, even if the proportion of oil component in the total amount should be below 10 % by weight. It should be noted, however, that if the proportion of high-activity calcium oxide component is to be increased,and the 2 6 1 9 ( proportion of water or wood vinegar liquid component is to be increased accordingly, the proportion of oi! component should be decreased as a matter of course. In this case, the resulting powdery oil product should contain the less proportion of oil component with regard to all other components. If any powdery oil product contains the proportion of oil component that is below a certain value, it will lose its commercial value. So, such products will not meet any marketing needs. Thus, the upper limit of the proportion of the high-activity calcium oxide that should be added may be determined from the product marketability considerations, which may be set to 300 % by weight in relation to oil component. In the example described above, either water or wood vinegar liquid may be added, but, generally, fatty acids that contain more carbons, or any ester compounds thereof, can be dissolved in any organic solvent or solution containing any organic substances (such as wood vinegar liquid) more easily than in water. Thus, when using wood vinegar liquid, the reaction that produces oil powders can occur more quickly than when using water. As described earlier in connection with the high-activity calcium oxide according to the present invention, the powdery oil product that may be produced in the manner described above by adding the high-activity calcium oxide component can contain the oil component whose usefulness has not been affected. When using the wood vinegar liquid that causes the reaction, the resulting powdery oil product can contain the wood vinegar component as it is not altered. The high-activity calcium oxide component used in the above example may be obtained by baking egg shells at the temperature range of between 900°C and 1500°C or between 1200°C and 1300°C. It may be obtained by baking sea shells or anything that contains easy-to-extract pure calucium at high temperatures. In either case, the baking temperature should be at least above 900°C. Otherwise, no desired reaction can occur. Best Mode for Carrying Out the Invention The present invention is described in further detail by referring to the particular preferred embodiments thereof. (Embodiment 1) White eggshells are washed clean, and are allowed to dry under the ambient atmosphere. Although it is not required, this drying may be accomplished by using any external drying - 13 - 26 19 0 means. 40 kg of the dried eggshells are baked at 900*0 for five hours within the electric furnace where they are exposed to the air blow stream (80 cm^/min). Then, they are allowed to cool. Following the baking process, those eggshells are milled to fine powders until they can have the particle size of less than 1 mm. About 20 kg of high-activity calcium oxide is thus obtained. The baking time should preferably be set to five hours because this length of time is required to bake all the eggshells uniformly at 900*0 within the electric furnace. In other words, the baking time corresponds to the specific time required for baking the specific quantity of eggshells uniformly at the specific temperature, and therefore it may depend upon the parameters such as the amount of eggshells being baked, baking temperarture, and so on. The eggshells that have been baked should preferably be milled to fine powders until they can have the particle size of less than 1 mm because the product that results from the reaction of the produced high-activity calcium oxide can contain fine powders of uniform size formed by the reaction, and the reaction rate can be quickened. The activity that is provided by the high-activity calcium oxide according to this embodiment has been examined. To do this, 100 grams of the high-activity calcium oxide was provided, to which an equal quantity (100 grams, 100m 1) of wood vinegar liquid was added. A mixture of them was obtained by the stirring operation which continued to run for 30 seconds, and was then left until it settled. As time went, a small portion of the wood vinegar liquid appeared on the surface of the mixture in a sludge form. The mixture was then left to settle for about ten minutes. Then, cracks were found on the surface of the sludgy mixture, and moisture was evaporated from the mixture. The resulting product was found to contain the wood vinegar powders combined with the Ca fine powders. The further examination was conducted to check to see that there was the component of the wood vinegar liquid in the produced fine powders. The result showed that there was the component of the wood vinegar liquid that was combined with the high-activity calcium oxide which was added thereto. (Embodiment 2) White eggshells are washed clean, and are allowed to dry under the ambient atmosphere. Although it is not required, this drying may be accomplished by using any external drying means. 40 kg of the dried eggshells are baked at 1000 "O for five (5) hours within the electric furnace where they are exposed to the air blow stream (80 cm^/min). Then, they are - 14 - 26 1 9 allowed to cool. Following the baking process, those eggshells are milled to fine powders until they can have the particle size of less than 1 mm. About 20 kg of high-activity calcium oxide is thus obtained. The baking time should preferably be set to five hours because this length of time is required to bake all the eggshells uniformly at 1000*0 within the electric furnace. The eggshells that have been baked should preferably be milled to fine powders until they can have the particle size of less than 1 mm because the product that results from the reaction of the produced high-activity calcium oxide can contain fine powders of uniform size formed by the reaction, and the reaction rate can be quickened. The activity that is provided by the high-activity calcium oxide according to this embodiment has been examined. To do this, 100 grams of the high-activity calcium oxide was provided, to which an equal quantity (100 grams, 100m 1) of wood vinegar liquid was added. A mixture of them was obtained by the stirring operation which continued to run for 30 seconds, and was then left until it settled. As time went, a small portion of the wood vinegar liquid appeared on the surface of the mixture in a sludge form. The mixture was then left to settle for about seven minutes. Then, cracks were found on the surface of the sludgy mixture, moisture was evaporated from the mixture, and the uniform fine powders were produced in a moment The resulting product was found to contain the wood vinegar powders combined with the Ca fine powders. The further examination was conducted to check to see that there was the component of the wood vinegar liquid in the produced fine powders. The result showed that there was the component of the wood vinegar liquid that was combined with the high-activity calcium oxide which was added thereto. (Embodiment 3) White eggshells are washed clean, and are allowed to dry under the ambient atmosphere. Although it is not required, this drying may be accomplished by using any external drying means. 40 kg of the dried eggshells are baked at 1100 O for five (5) hours within the electric furnace where they are exposed to the air blow stream (80 cm^/min). Then, they are allowed to cool. Following the baking process, those eggshells are milled to fine powders until they can have the particle size of less than 1 mm. About 20 kg of high-activity calcium oxide is thus obtained. 2. £>19 The baking time should preferably be set to five hours because this length of time is required to bake all the eggshells uniformly at 1100*0 within the electric furnace. The eggshells that have been baked should preferably be milled to fine powders until they can have the particle size of less than 1 mm because the product that results from the reaction of the produced high-activity calcium oxide can contain fine powders of uniform size formed by the reaction, and the reaction rate can be quickened. The activity that is provided by the high-activity calcium oxide according to this embodiment has been examined. To do this, 100 grams of the high-activity calcium oxide was provided, to which an equal quantity (100 grams, 100m 1) of wood vinegar liquid was added. A mixture of them was obtained by the stirring operation which continued to run for 30 seconds, and was then left until it settled.

Then, cracks were found on the surface of the sludgy mixture, moisture was evaporated from the mixture, and the uniform fine powders were produced in a moment. The resulting product was found to contain the wood vinegar powders combined with the Ca fine powders. The further examination was conducted to check to see that there was the component of the wood vinegar liquid in the produced fine powders. The result showed that there was the component of the wood vinegar liquid that was combined with the high-activity calcium oxide which was added thereto. (Embodiment 4) White eggshells are washed clean, and are allowed to dry under the ambient atmosphere. Although it is not required, this drying may be accomplished by using any external drying means. 40 kg of the dried eggshells are baked at 1200*0 for five (5) hours within the electric furnace where they are exposed to the air blow stream (80 cm^/min). Then, they are alloweJ to cool. Following the baking process, those eggshells are milled to fine powders until they can have the particle size of less than 1 mm. About 20 kg of high-activity calcium oviJe is thus obtained. The baking time should preferably be set to five hours because this length of time is required to bake all the eggshells uniformly at 1200*C within the electric furnace. The eggshells that have been baked should preferably be milled to fine powders until they can have the particle size of less than 1 mm because the product that results from the Qk I 9 reaction of the produced high-activity calcium oxide car. contain fine powders of uniform size formed by the reaction, and the reaction rate can be quickened. The activity that is provided by the high-activity calcium oxide according to this embodiment has been examined. To do this, 100 grams of the high-activity calcium oxide was provided, to which an equal quantity (100 grams, 100m 1) of wood vinegar liquid was added. A mixture of them was obtained by the stirring operation which continued to run for 30 seconds, and was then left until it settled. As time went, a small portion of the wood vinegar liquid appeared on the surface of the mixture in a sludge form. The mixture was then left to settle for about six minutes. Then, cracks were found on the surface of the sludgy mixture, moisture was evaporaiei from the mixture, and the uniform fine powders were produced in a moment. The resulting product was found to contain the wood vinegar powders combined with the Ca fine powders. The further examination was conducted to check to see that there was the component of the wood vinegar liquid in the produced fine powders. The result showed that there was the component of the wood vinegar liquid that was combined with the high-activity calcium oxide which v/as added thereto. (Embodiment 5) White eggshells are washed clean, and are allowed to dry under the ambient atmosphere. Although it is not required, this drying may be accomplished by using any external drying means. 40 kg of the dried eggshells are baked at 1300°C for four (4) hours within the electric furnace where they are exposed to the air blow stream (80 cm^/min). Then, they are allowed to cool. Following the baking process, those eggshells are milled to fine powders until they can have the particle size of less than 1 mm. About 20 kg of high-activity calcium oxide is thus obtained. The baking time should preferably be set to four hours because this length of time is required to bake all the eggshells uniformly at 1300*0 within the electric furnace. The eggshells that have been baked should preferably be milled to fine powders until they can have the particle size of less than 1 mrr? because the product that results from the reaction of the produced high-activity calcium oxide can contain fine powders of uniform size formed by the reaction, and the reaction rate can be quickened. The activity that is prov'ded by the high-activity calcium oxide according to this embodiment has been examined. To do this, 100 grams of the high-activity calcium oxide 26 19 was provided, to which an equal quantity (100 grams, 100m 1) of wood vinegar liquid was added. A mixture of them was obtained by the stirring operation which continued to run for 30 seconds, and was then left until it settled. As time went, a small portion of the wood vinegar liquid appeared on the surface of the mixture in a sludge form. The mixture was then left to settle for six minutes. Then, cracks were found on the surface of the sludgy mixture, and moisture was evaporated from the mixture. The resulting product was found to contain the wood vinegar powders combined with the Ca fine powders. The further examination was conducted to check to see that there was the component of the wood vinegar liquid in the produced fine powders. The result showed that there was the component of the wood vinegar liquid that was combined with the high-activity calcium oxide which was added thereto. To compare with the high-activity calcium oxide obtained at 1300O in the current embodiment, the baking temperature was tentatively raised from 1300*0 up to 1500*0, and a new high-activity calcium oxide was obtained by using the same parameters as specified in the current embodiment, except for the changed baking temperature. The activity of the new high-activity calcium oxide obtained at 1500O was examined. No difference was noticed in the activity between the high-activity calcium oxide obtained at 1300*0 and that obtained at 1500O. The reaction rate at which the fine powders are obtained when the wood vinegar liquid is added to the high-activity calcium oxide was substantially the same for both. Thus, the upper baking temperature may be set to 1500O in terms of the efficiency and the cost effectiveness. (Comparison Case 1) White eggshells are washed clean, and are allowed to become dry under the ambient atmosphere. Then, the dried eggshells are baked at 800O for five hours within the electric furnace where they are exposed to the air blow stream (80 cm^/min). After this, they are allowed to cool. Those eggshells that have been baked and cooled are then milled to fine powders having the particle sizes of less than 1 mm. Calcium powders are thus obtained. The activity of the calcium obtained above was examined. To do this, a specific quantity of calcium was provided, to which the equal quantity by weight of wood vinegar liquid was added. They were mixed togther for 30 seconds by stirring, and were then left to settle. During that time, the mixture produced a gas with an odor, and also produced 2 6 19 0 4 bubbles. 24 hours later, it was found that the wood vinegar liquid and calcium remained to be separated (not chemically combined). As the result, no powders were obtained. It may be appreciated from this comparison case 1 that the calcium obtained at 800*0 provides a low activity, and the wood vinegar liquid cannot be formed into fine powders when it is added to the above calcium. (Comparison Case 2) Unslaked lime which was produced by baking a limestone at 900O for five hours is provided and crushed. This unslaked lime is the calcium oxide offered by Adachi Sekkai Kogyo Co., Ltd., Japan. The crushed unslaked lime and wood vinegar liquid were mixed together in equal quantites by weight. They produced an exothermic reaction momentarily, and moisture was evaporated. It was found that the mixture contained powders and gross solids irregularly. The gross solids contained solids formed like bubbles which turned to the blown color. The fine powders could not be obtained as a whole. The high-activity calcium oxide obtained in accordance with the present invention reacted with the wood vinegar liquid in a completely different manner from this comparison case where the known unslaked lime (CaO) reacted with the wood vinegar liquid. As compared with the comparison case, the fine powders can be formed by the high-activity calcium oxide of the present invention without affecting or altering the property of the wood vinegar component, and this represents the chemical change that was never found in the prior art. (Experiment 1) The high-activity calcium oxide obtained in accordance with the present invention and other calciums were examined to investigate their respective electric conductivity, colors of the calcium powders and powdering reaction with the liquid wood vinegar, and the following results were obtained. It is noted that the calciums used for the purpose of the experiment included the high-activity calcium oxide of the invention obtained at the baking temperatures of 1300O and 900O, respectively, the oyster shell calcium obtained at the baking temperatures of 1300O and 900*0, respectively, the unslaked lime (as offered by Adachi Sekkai Kogyo Co., Ltd., Japan). 2619 (1) Electric Conductivity The electric conductivity is the measure of the ability of a particular material to conduct current through a conductor. In the experiment, 1/10000 of each different calcium was added to purified water, and was solved therein. The electric conductivity was measured for each, based on the ion conduction. Difference in the ionization rate between each different calcium was determined from the magnitudes of the respective values measured for those calciums. In the modern nutrition science, it is the established fact that calcium cannot be absorbed without being ionized. Then, the ionization was determined by measuring the electric conductivity for each different calcium. The results of the experiment show that the high-activity calcium oxide of the invention obatined at the baking temperature of 1300*0 exhibits the highest electric conductivity, which means the highest ionization. It may be concluded from the above that the high-activity calcium oxide of the invention obtained at the baking temperature of 1300*0 can be absorbed in vivo (such as animals) more easily than the oyster shell calcium obtained at the baking temperature of 1300*0 and others , and performs the best. (2) Colors of the Calcium Powders The calciums being examined presented respective colors, which were observed and compared visually. The high-activity calcium oxide according to the present invention appears white, while the oyster shell calcium appears light cream. The unslaked lime also appears white, but the unslaked lime appears rather black as compared with the high-activity calicum oxide of the invention. (3) Reaction with Liquid Wood Vinegar How each different calcium contributes to forming the liquid wood vinegar into fine powders when reacting with the liquid wood vinegar was examined. The results show that uniform powders are obtained by the high-activity calcium oxide of the invention, while uniform powders are not obtained by the other calciums. The following table 1 summarizes the results obtained during the experiment. Table 1 26 1 9 0 k Calciums examined Conductivity (*) Powder Color Result following the Reaction high-activity calcium oxide (1300O) 0.664 ms/cm white clean unifom fine powders high-activity calcium oxide (900O) 0.411 ms/cm white clean uniform fine powders oyster shell calcium (1300O) 0.523 ms/cm light cream no powders, solid oyster shell calcium (900O) 0.427 ms/cm light cream no powders, solid unslaked lime 0.390 ms/cm white bubble solids and non-solids, no uniform powders as a whole (* diluted to 10000 times the amount of the purified water) (Experiment 2) The calciums being examined included the high-activity calcium oxide of the invention obtained at the baking temperature of 1300*0, the unslaked lime (CaO 98%) (as offered by Adachi Sekkai Kogyo Co., Ltd., Japan), and the reagent calcium oxide (CaO 99.9%) (as offered by Wako Junyaku, Japan). Those calciums were examined to verify their respective antidiarrhoea effect for rat models using the castor oil that causes diarrhoea. SLC: Four SD male rats (four weeks old, weighing 100 g.to 150 g.) were given 10 mg/kg, 30 mg/kg, and 100 mg/kg of each of the those three kinds of CaO through the mouth, as shown below. In addition, physiological saline was also given as a control through the mouth. After thirty minutes, lm 1 of castor oil was given through the mouth, and the antidiarrhoea effect was checked for each dose using the following formula.

Those calciums were examined to verify their respective antidiarrhoea effect for rat models using the castor oil that causes diarrhoea. SLC: Four SD male rats (four weeks old, weighing 100 g.to 150 g.) were given 10 mg/kg, 30 mg/kg, and 100 mg/kg of each of the those three kinds of CaO through the mouth, as shown below. In addition, physiological saline was also given as a control through the mouth. After thirty minutes, lm 1 of castor oil was given through the mouth, and the antidiarrhoea effect was checked for each dose using the following formula. - 22 - 2 6 19 time to manifest diarrhoea for specimen total excrements = antidiarrhoea index time to manifest diarrhoea for control total excrements (Note: the antidiarrhoea of one for the control is assumed.) The following table 2 shows the values as measured and the corresponding respective antidiarrhoea indices as calculated.

Particularly, for the dose of 100 mg/kg, no diarrhoea was manifested within two hours. 26 19 04 (Embodiment 6) 2000 grams of raw blood from pigs butchered or killed for food at the slaughter house and 2000 grams of high-activity calcium oxide obtained by baking egg shells at the specific high temperatures are placed in the reactor container where they are stirred and mixed together at a slow rate. In 30 to 40 minutes, the reaction begins to occur between the two, and is completed in 10 to 15 minutes after the beginning of the reaction. During the reaction, its temperature reaches 80*C to 100"C. The moisture or water content is found to be evaporating at those temperatures. Then, the resulting mixture is allowed to cool at the ambient room temperature for 30 to 60 minutes. The reaction product that is then obtained presents the moss green color and has the soft state containing voids. This reaction product may be formed into poweders having mesh sizes almost equal to 100 by simply crashing it. Those powders amount to about 3200 grams. The following Tables 3,4 and 5 show the results obtained by analizing the components contained in the blood powders that have been formed in the manner described above. Table 3.

In this embodiment, the usual vertical-type stirrer is used, and is operated at 60 rpm (revolutions per minute). The uniform mixture may be obtained by running the stirrer for ten or less minutes. This stirring operation may be monitored visually, and it may be stopped within ten minutes from the beginning of the running of the stirrer at the time when the uniform reaction begins to take place. The high-activity calcium oxide that is used in this embodiment may be obtained in the following manner. First, white egg shells are washed clean, and are left until they become dry. Although it is not required, this drying may be done by using any drying means. Then, 40 kg of those egg shells are baked at 900"C for five hours within the electric furnace where they are exposed to the air blow flow (80 cm^/min), and are then allowed to cool. The white egg shells thus obtained are milled to fine particles. Those particles should have the size of less than 1 mm. The result contains a high-activity calcium oxide equal to about 20 kg. The baking time should preferably be set to five hours because this length of time is required to bake all the egg shells uniformly at 900*0. Similarly, the egg shells that have been baked should preferably be milled to particle sizes of less than 1 mm because the high-activity calcium Gxide thus obtained and containing those particle sizes can more readily react with the blood at the higher rate, producing a uniform powdery blood product. (Example of Use 1) 0.1 kg of liquid wood vinegar and 10 kg of filler in the form of charcoal powders are added to one kg of the powdery blood product obtained in the embodiment 6. The n, they are mixed together, and the resulting mixture passes through the granulating device which provides granules of one (1) mm to three (3) mm in diameter. Those granules may be added - 27 - 26 1 9 0 A to a particular animal feed in the appropriate proportions. When the granules are used with a particular fertilizer, 0.1 to 1.0 % by weight, for example, may be added. (Embodiment 7) 2000 grams of raw blood from pigs butchered for food in the slaughter house and 2000 grams of high-activity calcium oxide obtained by baking sea shells (oyster shell) at the particular high temperatures are placed in the reactor container where they are stirred and mixed together at a slow rate. In 30 to 40 minutes, the reaction begins to occur between the two, and is completed about 15 minutes after the beginning of the reaction. Then, the resultant mixture is allowed to cool at the ambient room temperature for 30 to 60 minutes. The reaction product that is then obtained presents the moss green color and has the soft state containing voids. This reaction product may be formed into powders having mesh size almost equal to 100 by simply crashing it. Those powders amount to about 3200 grains. The components contained in the powders are analyzed, and it is found that the powders retain virtually all of the useful elements or components that are originally contained in the killed pigs' raw blood, without having their respective properties unaffected such as by the alteration that would otherwise be possible. The high-activity calcium oxide that is used in this embodiment may be obtained in the following manner. First, sea shells are washed clean, and are left until they become dry. Although it is not required, this drying may be done by using any drying means. Then, 40 kg of those sea shells are baked at 1000*0 for five hours within the electric furnace where they are exposed to the air blow flow (80 cm^/min), and are then allowed to cool. The sea shells thus obtained are milled to fine particles. Those particles have the size of less than 1 mm. The result contains a high-activity calcium oxide equal to about 20 kg. The baking time should preferably be set to five hours because this length of time is required to bake all the sea shells uniformly at 1000*C. Similarly, the sea shells that have been baked should preferably be milled to particle sizes of below 1 mm because the high-activity calcium oxide thus obtained and containing those particle sizes can more readily react with the blood at the higher rate, producing a uniform powdery blood product. This embodiment shows that some calcium oxide obtained by baking sea shells at the particular high temperatures may have the reactivity for causing the powdering reaction. (Experiment 3) - 28 - 26 19 0 A high-activity calcium oxide of the present invention (which was obtained by baking egg shells at the bak'ng temperature of 1250t)) and a raw blood that was collected from a rat (SLC:SD male rat six weeks old and weighing 250 gram to 300 gram) were used for the purpose of the current experiment. Five sample compositions were prepared, each sample composition containing a fixed quantity of rat blood that is equal to 5 ml (about 5 gram) and a varying quantity of the high-activity calcium oxide that is equal to 5 gram, 3.5 gram, 2.5 gram, 1.5 gram, and 0.5 gram, respectively. Then, each sample composition '"/as subjected to the stirring process. For each resulting mixture, the state of the powders that would be formed four (4) hours and twenty-four (24) hours after the reaction began, respectively, was examined. The results are given as the below Table 6. Table 6 Q'ty of high-activity calcium oxide (g) 5 3.5 2.5 1.5 0.5 Ratio (by weight) of blood/calcium oxide 1:1 1.07 1:0.5 1:0.3 1:0.1 Powder formed or not after 4 hours yes yes no no no Powder formed or not after 24 hours yes yes yes no no Conclusion: As it can be seen from the above results, the preferred mixture ratio of the raw rat blood and high-activity calcium oxide should be such that 0.5 or more part by weight of the high-activity calcium oxide is supplied for one part by weight of the rat blood. It can also be seen that when it is desired that powders are formed in a relatively short time after the reaction occurs, 0.7 or more part by weight of the high-activity calcium oxide should preferably be supplied for one part by weight of the rat blood. 1G 1 % (Experiment 4) This experiment took place under the same conditions as for the preceding experiment 3. 0.1% by weight of propionic acid calcium was added to each sample composition. Then, for each sample composition, the state of the powders that would be formed 4 hours and 24 hours after the reaction began, respectively, was examined, and the results, which are given below Table 7, were compared with those obtained in the experiment 3. Table 7 Q'ty of high-activity calcium oxide (g) 5 3.5 2.5 1.5 0.5 Ratio (by weight) of blood/calcium oxide 1:1 1.07 1:0.5 1:0.3 1:0.1 Powder formed or not after 4 hours yes yes yes no no Powder formed or not after 24 hours yes yes yes yes no By adding 0.1 % by weight of propionic acid calcium, the proportion of the high-activity calcium oxide can be reduced as compared with that in the experiment case 3, and the powders can be formed. The time required for forming the powders can also be reduced. (Experiment Case 5) This experiment took place under the same conditions as for the preceding experiment 3. 0.5% by weight of sorbic acid sodium was added to each sample composition. Then, for each sample composition, the state of the powders that would be formed 4 hours and 24 hours after the reaction began, respectively, was examined, and the results, which are given below Table 8, were compared with those obtained in the experiment 3. Result: - 30 - Table 8 36 1 9 0 4 Q'ty of high-activity calcium oxide (g) 5 3.5 2.5 1.5 0.5 Ratio (by weight) of blood/calcium oxide 1:1 1.07 1:0.5 1:0.3 1:0.1 Powder formed or not after 4 hours yes yes yes no no Powder formed or not after 24 hours yes yes yes yes no Result: By adding 0.5% by weight of sorbic acid sodium, the proportion of the high-activity calcium oxide can be reduced as compared with that in the experiment case 3, and the powders can be formed. The time required for forming the powders can also be reduced. Conclusion: As the high-activity calcium oxide is alkaline, the amount of the high-activity calcium oxide can be reduced by adding a slight amount of any organic acid salt, such as propionic acid calcium or sorbic acid sodium, that presents acidity, or any organic acid that is required for forming the powders. The time required for forming the powders can also be reduced. It may be appreciated that if the slight amount of any organic acid salt such as propionic acid calcium or sorbic acid sodium is added, the proportion of the high-activity calcium oxide may preferably be 0.3 or more part by weight for one part by weight of the raw animal blood. If it is desired that the powders are formed in a relatively short time after the reaction begins, it may preferably be 0.5 or more part by weight (Embodiments) 100 grams of cuttle fish oil was prepared, to which 20 grams of liquid wood vinegar and 120 grams of the powders of the high-activity calcium oxide of the invention obtained at the 2619 04 baking temperature of 1300*0 were added. They were then mixed together by stirring, and were allowed to settle. The reaction was completed in ten minutes, and the result contained finely powdered cuttle fish oil, which was equal to 230 grams. The components contained in the resultant cuttle fish oil powders were analyzed, and it was found that all of the components listed below remained as they were originally contained in the cuttle fish oil. The components that remained are: myristic acid, pentadecanoic acid, palimitic acid, hexadecanoic acid (n-11), hexdecanoic acid (n-5), palmitoleic acid, hexadecanoic acid (n-9), stearic acid, octadecanoic acid (n-5), octadecanoic acid (n-7), oleic acid, linoleic acid, octadecatetraenoic acid ( n-3), eicosanoic acid (n-11), eicosanoic acid (n-7), eicosanoic acid (n-9), eicosagenoic acid (n-6), diphomo- Y -linoleic acid, eicosatraenic acid (n-3), arachidonic acid, eicosapentaenoic acid, docosanoic acid (n-11), docosanoic acid (n-7), erucic acid, docosapentaenoic acid (n-3), docosahexsaenoic acid (n-3), and tetracosanoic acid (n-9). It is known that the conventional powdered calcium oxide does not react chemically with liquid oils alone, which are only abosorbed by the powdered calcium oxide. The powders thus formed contains the viscosity of oils. It is impossible to remove the viscosity of oils from the formed powders. In contrast, the high-activity calcium oxide according to the present invention can be used with any liquid oils, and the resulting powders are formed with ease, from which the viscosity has been removed. Those powders may be formed simply by allowing the high-activity calcium oxide to react chemically with oils as well as liquid wood vinegar. No additional processes such as mixing, heating, etc. that occur in the prior art are rer iired. (Embodiment 9) 100 grams of frying oil was provided, to which 120 grams of the high-activity calcium oxide of the invention obtained at the baking temperature of T200*C and 20 grams of water were added. They were mixed together in the vessel by stirring gently , and the resultant mixture was allowed to settle. In six minutes, the result contained finely powdered frying oil, which was equal to 230 grams. (Embodiment 10) 100 grmas of frying oil was provided, to which 120 grams of the high-activity calcium oxide of the invention obtained at the baking temperature of 1200*C and 20 grams of liquid 2 6 19 0 wood vinegar were added. They were mixed together in the vessel by stirring gently, and the resultant mixture was allowed to settle. In three minutes, the result contained finely powdered frying oil, which was equal to 230 grams. It may be appreciated from the embodiments 9 and 10 that oils may be powdered by adding either water or liquid wood vinegar to allow the liquid oil and the high-activity calcium oxide to react with each other. The liquid wood vinegar causes the reaction more quickly. In general, this is because fatty acids containing more carbons or ester compounds thereof are more easily solved by organic solvents or solutions containing organic substances (e.g., liquid wood vinegar) than by water. Thus, it appears that using the liquid wood vinegar, rather than using water, quickens the reaction which forms the oils into fine powders. As the before described Embodiments X to 10 and Experiments 1 and 3 to 5, the high-activity calcium oxide according to the present invention provides the activity that aids in forming the specific moisture-contained substances into fine powders without losing any resolvable components in the moisture-contained substance and without affecting or altering the properties of those resolvable components. It may thus be appreciated that the high-activity calcium oxide according to the present invention is useful as the powdering agent which c^n form the moisture-contained substances into the fine powders. (Comparison Case 3) 100 grams of fry oil, 110 grams of powdery high-activity calcium oxide and 10 grams of water were placed into a vessel where they were mixed together by stirring. The resulting mixture was left until the reaction was completed. The reaction was completed in 15 minutes, and the product that resulted from the reaction contained powdered oil that was sticky like clay. It is found from the above that the ratio of the particular oil, such as fry oil in this case, and water being 1 : 0.1 by weight is a boundary on which whether the chemical reaction between those two components by which oil can be formed to powders can be caused or not (Comparison Case 4) 100 grams of fry oil, 200 grams of powdery high-activity calcium oxide and 100 grams of wood vinegar liquid were placed into a vessel where they were mixed together by stirring. The resulting mixture was left until the reaction was completed. The reaction was completed - 33 - </div>
