Description

  The present invention relates to aloe vera water mainly composed of aloe vera and a method for producing the same.

  Aloe vera contains organic acids such as folic acid and malic acid in addition to vitamin C. Since such organic acids promote the production of intercellular lipids, it is known that aloe vera has a skin moisturizing effect. Therefore, conventionally, the lotion using the aloe vera water extracted from the aloe vera is manufactured (for example, refer patent document 1).

  Conventional aloe vera water is manufactured in the following manner. First, only the pulp part is extracted from the cut aloe vera. The pulp portion is heat sterilized after being finely crushed. In this treatment, for example, the pulp is heated for 30 minutes in an environment of 85 ° C. Finally, the pulp is filtered and purified as aloe vera water.

Japanese Patent Application Laid-Open No. 9-143047

  However, in the conventional manufacturing method, pulp fibers are contained in the purified aloe vera water. For this reason, the purified aloe vera water is unstable and easily rotted, and preservatives have been used for long-term storage. Moreover, aloe vera water is also accompanied by a generally unpleasant odor. Therefore, conventionally, a lotion with 100% aloe vera water has been unattractive as a product despite being excellent as a cosmetic liquid. Under such circumstances, in the lotion containing conventional aloe vera water as a component, the content of aloe vera water is limited to about 20%, and as a result, it has been difficult to achieve a high moisturizing effect on the skin.

  Accordingly, an object of the present invention is to provide an aloe vera water that is excellent as a cosmetic liquid, can be stored for a long period of time, and has little odor, and a method for producing the same.

  (1) In order to achieve the above object, the method for producing aloe vera water according to the present invention includes the following seven steps. A first cleaning step of cleaning the surface of the aloe vera fresh leaves with a sodium hypochlorite solution; A pulp removal step of removing the epidermis from the washed raw leaves and extracting the pulp. A second washing step for washing the pulp to remove aloin from the pulp. A crushing process that crushes the pulp from which aloin has been removed. Filtrate purification step of purifying the filtrate by filtering the crushed pulp. A heat sterilization step of heating the filtrate at a predetermined temperature for a predetermined time. A distillation process in which the filtrate subjected to heat sterilization is subjected to low-pressure low-temperature distillation.

  The harvested aloe vera leaves are washed with sodium hypochlorite solution. This removes dirt and germs attached to the surface of the fresh leaves of Aloe vera. Then, the epidermis is peeled off from the raw leaves, and only the flesh is taken out. The pulp is further washed to remove aloin, which is a bitter component. The pulp from which aloin has been removed is finely crushed and filtered to refine the filtrate. This filtrate also contains aloe vera fiber components and germs. The filtrate is then distilled. Distilled water obtained by this distillation does not contain aloe vera fiber components, so it is hard to rot and has little odor. In addition, since the filtrate is distilled under low temperature and low pressure, the destruction of vitamin C and organic acids, which are components of aloe vera, is suppressed.

  (2) A heating step of heating the distillate obtained by the distillation step to a temperature exceeding 120 ° C. and not more than 125 ° C. may be further provided.

  By this heating step, the bacteria contained in the distilled water, that is, aloe vera water, are almost completely annihilated. Therefore, aloe vera water is a very stable substance.

  (3) In the distillation step, the temperature is preferably set to 47 ° C or more and 53 ° C or less.

  When the temperature is lower than 47 ° C., the odor remains in distilled water. In addition, when the temperature is higher than 53 ° C., vitamin C in particular is destroyed among the components contained in aloe vera. By distilling in the above temperature range, the odor is suppressed while the destruction of the components is suppressed.

  (4) Moreover, since the said objective is achieved, it is preferable that the aloe vera water based on this invention is manufactured by distilling with the manufacturing method of the above-mentioned aloe vera water.

  As described above, the cut aloe vera leaves are washed with a sodium hypochlorite solution. This removes dirt and germs attached to the surface of the fresh leaves of Aloe vera. Then, the epidermis is peeled off from the raw leaves, and only the flesh is taken out. The pulp is further washed to remove aloin, which is a bitter component. The pulp from which aloin has been removed is finely crushed and filtered to refine the filtrate. This filtrate also contains aloe vera fiber components and germs. The filtrate is then distilled. Distilled water obtained by this distillation does not contain aloe vera fiber components, so it is hard to rot and has little odor. In addition, since the filtrate is distilled under low temperature and low pressure, the destruction of vitamin C and organic acids, which are components of aloe vera, is suppressed.

  According to the present invention, aloe vera water that can be stored for a long time and has little odor is provided. This aloe vera water contains organic acids such as vitamin C, folic acid and malic acid, and is excellent as a cosmetic liquid. As a result, when this aloe vera water is used as a lotion, it has a very high moisturizing effect.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 is a flowchart showing a method for producing aloe vera water according to an embodiment of the present invention.

  Aloe vera water produced by this method contains abundant nutritional components (vitamin C, calcium, sodium, potassium, iodine as well as organic acids such as amino acids, folic acid, malic acid, etc.) originally contained in the raw material aloe vera. Yes. As will be described later, the feature of the method for producing aloe vera water according to the present embodiment is that it includes a distillation step (S7) for distilling aloe vera juice from which the fruit of aloe vera is squeezed. Aloe vera water obtained through the process can exhibit a high beauty effect.

  As shown in the figure, this manufacturing method includes seven steps. That is, this manufacturing method includes the first washing step S1, the pulp removal step S2, the second washing step S3, the crushing step S4, the filtrate purification step S5, the heat sterilization step S6, and the distillation step S7. Hereinafter, each step will be described in detail.

(1) First cleaning process

  FIG. 2 is a flowchart showing the details of the first cleaning step.

  As shown in the figure, aloe vera is first cut down and fresh leaves are collected (S11). It is determined whether the collected raw leaves satisfy a predetermined size or weight and have sufficient pulp (S12). If the collected fresh leaves do not have sufficient pulp (S12: N), the fresh leaves are discarded (S15). It is also discarded if the fresh leaves are damaged or not healthy.

  When the fresh leaves have a predetermined size and weight (S12: Y), they are washed with water. At this time, the fresh leaves are gently washed with a brush in running water (S13). As a result, dirt, dust, etc. adhering to the surface of the fresh leaves are removed. Next, the surface of the fresh leaves washed with water is inspected (S14). When the surface of the fresh leaf is damaged or when the color is not healthy (S14: Y), the fresh leaf is discarded. When the fresh leaves are not damaged (S14: N), the fresh leaves are sterilized.

  This sterilization process is performed by washing fresh leaves with sodium hypochlorite (S16). Specifically, a sodium hypochlorite solution is stored in the sink, and fresh leaves are immersed in this for a predetermined time. The concentration of the sodium hypochlorite solution is exemplified by 200 ppm. But the density | concentration of a sodium hypochlorite liquid can be set in the range of 150 ppm-200 ppm. Moreover, in this embodiment, although a fresh leaf is immersed only for 5 minutes, according to the density | concentration of a sodium hypochlorite liquid, the time for which a fresh leaf is immersed can be set in the range of 5 minutes-6 minutes.

  When the fresh leaves are immersed in the sodium hypochlorite solution, various bacteria attached to the surface of the fresh leaves are killed. Thereafter, the fresh leaves are washed with water (S17). Specifically, it is cleaned with a brush in running water at room temperature. The washing time is about 3 to 4 seconds per fresh leaf. As a result, dirt and germs on the surface of fresh leaves are removed cleanly.

(2) Pulp extraction process

  In the pulp removal step (S2) (see FIG. 1), only the pulp portion is extracted from the raw leaves. Specifically, the raw leaves are peeled, and the upper and lower parts and the left and right parts of the fresh leaves are cut. In addition, this process may be performed by a known pulp extractor.

(3) Second cleaning step

  FIG. 3 is a flowchart showing the details of the second cleaning step.

  In the second cleaning step (S3), first, the extracted pulp portion is separated (S31). Then, the pulp part is washed with water (S32). Specifically, the pulp portion is collected in a sink and washed while being rinsed in running water. Thereby, the aloin which is a bitter component (yellow component) contained in the pulp part is removed. Whether or not the bitter component has been removed is determined by the color of the water being washed (S33). That is, if the water being washed is yellow, the bitter component has not been sufficiently removed (S33: N), and further washed in running water (S32). On the other hand, when the color of the water being washed becomes transparent or nearly transparent, the bitter component is sufficiently removed (S33: Y).

  The pulp part from which the bitter component has been removed is sufficiently drained (S34) and stored refrigerated (S35). In this embodiment, the refrigeration temperature is set to 5 ° C. However, the refrigeration temperature can be set in the range of 4 ° C to 9 ° C.

(4) Crushing process

  FIG. 4 is a flowchart showing the crushing process in detail.

  The refrigerated and preserved pulp portion is finely crushed by a crushing device (S41). As the crusher, a so-called chopper is typically employed. Thereby, the said pulp part is cut | disconnected in a granule. It is determined whether or not the cut flesh grain has a predetermined size (S42). When the grain of the pulp is larger than the predetermined size (S42: N), the pulp is crushed again. When the grain of the pulp is smaller than the predetermined size (S42: Y), the granular pulp is stored in the tank by a predetermined amount and laid down (S43).

  Thereafter, the granular pulp is heated by a heating device (S44). Thereby, sterilization of the pulp is performed. In this embodiment, the heating temperature is set to 85 ° C. However, the heating temperature can be appropriately set in the range of 83 ° C to 87 ° C. However, when the heating temperature is set higher than this temperature range, vitamin C and the like contained in the pulp may be destroyed. Further, when the heating temperature is set lower than the above temperature range, there is a possibility that sufficient sterilization may be impossible.

  The pulp is heated for a predetermined time. That is, it is determined whether or not a predetermined time has elapsed since the pulp was heated to a predetermined temperature (S45). In the present embodiment, this predetermined time is set to 30 minutes. However, the predetermined time can be set to about 28 minutes to 32 minutes. Therefore, after the pulp has been heated to a predetermined temperature, if the predetermined time has not elapsed (S45: N), the heating is further continued. If the predetermined time has elapsed after the pulp is heated to a predetermined temperature (S45: Y), the heat treatment is completed (S46).

(5) Filtrate purification process

  As shown in FIG. 1, the heat-treated pulp is filtered (S5). Specifically, the granular pulp is put into a stainless steel bowl and roughly filtered, and then filtered through a filter cloth. The filter cloth has a hole of about 200 μm. Therefore, the granular pulp filtered by this filter cloth is refined as a filtrate containing coarse fibers from which coarse fibers are removed. That is, this filtrate is aloe vera juice containing a fiber component.

(6) Heat sterilization process

  FIG. 5 is a flowchart showing the heat sterilization process in detail.

  The filtrate is stored in a heat sterilizer (S61). Thereafter, the filtrate is heated to a predetermined temperature (S62). By this process, in this embodiment, this temperature is set to 85 ° C. However, the heating temperature can be appropriately set in the range of 84 ° C to 86 ° C. Similarly to the above, when a temperature higher than this temperature range is set, vitamin C and the like contained in the filtrate may be destroyed. Further, when a temperature lower than the above temperature range is set, there is a possibility that sufficient sterilization may not be possible.

  The filtrate is heated for a predetermined time. That is, it is determined whether or not a predetermined time has elapsed since the pulp was heated to a predetermined temperature (S63). In this embodiment, this predetermined time is set to 10 minutes. However, the predetermined time can be set to about 9 to 11 minutes. Therefore, after the pulp has been heated to a predetermined temperature, if the predetermined time has not elapsed (S63: N), the heating is further continued. Further, if the predetermined time has elapsed after the pulp is heated to a predetermined temperature (S63: Y), the heat sterilization process is completed (S64).

(7) Distillation process and heating process

  FIG. 6 is a flowchart showing the distillation process in detail. In the present embodiment, the heating process described later is included in the distillation process.

  The filtrate that has been subjected to the heat sterilization treatment is filled in a distillation apparatus (S701). This distillation apparatus can perform vacuum distillation, and distills the filtrate under the temperature and pressure described below.

  First, the inside of the distillation apparatus is depressurized (S702). In the present embodiment, the pressure in the distillation apparatus is set to a predetermined pressure corresponding to the distillation temperature. Subsequently, the filtrate is heated under this pressure (S703). In this embodiment, the filtrate is heated to 50 ° C. That is, the distillation temperature is 50 ° C. Since the inside of the distillation apparatus is set to the above pressure, the filtrate is boiled and distilled at 50 ° C. However, the distillation temperature can be set in the range of 47 ° C to 53 ° C. And the pressure in a distillation apparatus is adjusted so that a filtrate will boil in this temperature range.

  Therefore, it is determined whether or not the distillation temperature is within a range of 47 ° C. to 53 ° C. (S704, S705). First, it is determined whether the distillation temperature is 47 ° C. or higher (S704). When the distillation temperature is lower than 47 ° C. (S704: N), the filtrate is further heated (S703). When the distillation temperature is 47 ° C. or higher (S704: Y), it is next determined whether or not the distillation temperature is 53 ° C. or lower (S705). When the distillation temperature is higher than 53 ° C. (S705: N), the filtrate is cooled (S706). When the distillation temperature is 53 ° C. or lower (S705: Y), the distillation process is started (S707). That is, aloe vera water (distilled water) is distilled from the filtrate. The effect by setting the said distillation temperature to 47 to 53 degreeC is mentioned later.

  Next, the aloe vera water is heated (heating step: S708 to S711). This heating temperature can be set to more than 120 ° C. and 125 ° C. or less. In this embodiment, the heating temperature is set to 121 ° C. By providing this heating step, the germs in the Aloe Vera water are completely killed.

  It is determined whether the temperature T of the aloe vera water is 121 ° C. or higher (S709). When the temperature T of the aloe vera water is lower than 121 ° C. (S709: N), the aloe vera water is further heated (S708). When the temperature T of the aloe vera water is 121 ° C. or higher (S709: Y), the aloe vera water is heated as it is for a predetermined time. That is, it is determined whether the temperature T of the aloe vera water is 121 ° C. or higher and a predetermined time has elapsed (S710). In this embodiment, this predetermined time is set to 10 minutes. However, this heating time can be set to about 7 to 11 minutes. Therefore, after the aloe vera water is heated to 121 ° C. or more, if the predetermined time has not passed (S710: N), the heating is further continued, and after the aloe vera water is heated to 121 ° C., the predetermined time has passed. If so (S710: Y), this heat treatment is completed (S711). The effect of the heating temperature exceeding 120 ° C. and being set to 125 ° C. or less will be described later.

  In the present embodiment, aloe vera water is obtained by distilling aloe vera juice. Therefore, the aloe vera water does not contain the fiber component of aloe vera, is not easily spoiled, can be stored for a long period of time, and has little odor. Moreover, since aloe vera water is obtained by low temperature distillation, the aloe vera water is rich in vitamin C and organic acids. Therefore, this aloe vera water is excellent as a cosmetic liquid and is suitable as a skin lotion having an extremely high moisturizing effect.

  In this embodiment, the bacteria contained in the distilled aloe vera water are almost annihilated by the heating step. Moreover, since the heating temperature is set to be higher than 120 ° C. and not higher than 125 ° C., thermal alteration of aloe vera water is prevented. Therefore, aloe vera water becomes a very stable substance, and high quality as a lotion can be maintained. But the said heating process S708-S711 can also be abbreviate | omitted.

  In particular, in the distillation step, the distillation temperature is set to 47 ° C. or more and 53 ° C. or less. When the distillation temperature is lower than 47 ° C., the odor remains in the aloe vera water. Further, when the distillation temperature is higher than 53 ° C., vitamin C in particular is destroyed among the components contained in aloe vera. In this embodiment, there is an advantage that the odor can be suppressed while the destruction of the components is suppressed by being distilled in the above temperature range.
