本発明は水に対して溶解性が良好で、低温でも水に溶け易くなる高溶解性の水酸化カルシウム溶液に関する。 The present invention relates to a highly soluble calcium hydroxide solution that has good solubility in water and is easily soluble in water even at low temperatures.
一般に水酸化カルシウムは、酸化カルシウムに水を加えて得られていた。この水酸化カルシウムの溶解性は、水２０℃で１００mlに対して０．１６１ｇ溶解するだけで、水には難溶性であった。 In general, calcium hydroxide has been obtained by adding water to calcium oxide. The solubility of this calcium hydroxide was only 0.161 g with respect to 100 ml at 20 ° C., and it was hardly soluble in water.
水酸化カルシウムの提案としては、特開平５−１９３９９７号公報，特開２００４−４３３０３号公報，特開２０１０−５９０３４号公報等がある。特開平５−１９３９９７号は輸送時、貯蔵時にパイプやタンク内で付着、固結し難い粉末状水酸化カルシウムの提案であり、特開２００４−４３３０３は工業的に有利に製造すると共に、安価で、比表面積が大きく流動性を良好とさせた水酸化カルシウムの提案であった。また特開２０１０−５９０３４は結晶径を大きくする水酸化カルシウムの提案であった。これらの水酸化カルシウムは物性を変えるものであり、本発明のように高溶解性のものは従来になく、且つ、水酸化カルシウムの物性全般を変えずに、高溶解性を確保するような発想もないものであった。 As proposals of calcium hydroxide, there are JP-A-5-193997, JP-A-2004-43303, JP-A 2010-59034, and the like. Japanese Patent Laid-Open No. 5-193997 proposes powdered calcium hydroxide that hardly adheres and solidifies in pipes and tanks during transportation and storage, and Japanese Patent Laid-Open No. 2004-43303 is industrially advantageous and inexpensive. It was a proposal of calcium hydroxide having a large specific surface area and good fluidity. Japanese Patent Application Laid-Open No. 2010-59034 proposed a calcium hydroxide having a large crystal diameter. These calcium hydroxides change the physical properties, and there has never been a highly soluble one like the present invention, and the idea of ensuring high solubility without changing the overall physical properties of calcium hydroxide. There was nothing.
本発明は水に対して溶解性が良好で、低温でも水に溶け易くなると共に食品のカルシウム強化と日持ち向上用及び食肉の物性改良用として利用できる高溶解性の水酸化カルシウム溶液を提供することを目的とする。 The present invention provides a high-solubility calcium hydroxide solution that has good solubility in water and is easily soluble in water even at low temperatures, and can be used for strengthening calcium and improving shelf life of foods and improving physical properties of meat. With the goal.
本発明は上記現状に鑑みて成されたものであり、つまり、砂糖５０％重量の糖液を、或いは砂糖３０％重量とキシリトール２０％重量の混合した糖液を、４０〜８０℃に保温し、その中に、原料の焼成カルシウムが飽和状態を限度で含む高溶解性の水酸化カルシウム溶液であって、該水酸化カルシウム溶液は、糖液１００部と、酸化カルシウム７〜１５部とから成ると共にその溶液がＰＨ１２〜ＰＨ１３である。尚、本発明で言う「水酸化カルシウム溶液」とは、糖液に水酸化カルシウムが、水に溶け込む量よりも数倍多く溶け込まれた状態の溶液を指すものとする。また「飽和状態を限度で加え」とは、糖液中に焼成カルシウムを濁る直前まで加えることを指し、更に「高溶解性」とは、単に水に溶け込む従来の量に対して、糖液を介することによって、従来の量よりも５倍以上の量が水に溶け込むようになることを指すものとする。 The present invention has been made in view of the above situation, that is, a sugar solution of 50% by weight of sugar or a mixture of 30% by weight of sugar and 20% by weight of xylitol is kept at 40 to 80 ° C. , Among them, a highly soluble calcium hydroxide solution containing calcined calcium as a raw material up to the saturation state, the calcium hydroxide solution comprising a sugar solution 100 parts and calcium oxide 7-15 parts And the solution is PH12-PH13. The “calcium hydroxide solution” referred to in the present invention refers to a solution in which calcium hydroxide is dissolved in the sugar solution several times more than the amount dissolved in water. “Add saturation to the limit” refers to adding calcined calcium to the sugar solution until just before turbidity, and “high solubility” means that the sugar solution is simply dissolved in water compared to the conventional amount. By interposing, the amount 5 times or more than the conventional amount will be dissolved in water.
請求項１のように砂糖５０％重量の糖液を、或いは砂糖３０％重量とキシリトール２０％重量の混合した糖液を、４０〜８０℃に保温し、その中に、原料の焼成カルシウムが飽和状態を限度で含む高溶解性の水酸化カルシウム溶液であって、該水酸化カルシウム溶液は、糖液１００部と、酸化カルシウム７〜１５部とから成ると共にその溶液がＰＨ１２〜ＰＨ１３であることにより、高溶解性を有するため、水に対して溶解性が良好で、低温でも従来よりも水に多く溶けると共に食品のカルシウム強化と日持ち向上用及び食肉の物性改良用として利用できるものとなる。しかも、水酸化カルシウムの物性全般を変えることなく、水酸化カルシウムを溶け易くしたものとなるため、従来と同様にして使用出来るものとなる。更に本発明品は極めて簡単な製造方法で、且つ、容易に得られるものとなり、安価に提供することが可能である。 A sugar solution containing 50% sugar by weight or a mixture of 30% sugar by weight and 20% by weight xylitol is kept warm at 40 to 80 ° C., and the raw calcined calcium is saturated therein. It is a highly soluble calcium hydroxide solution containing the state as much as possible, and the calcium hydroxide solution is composed of 100 parts of sugar solution and 7 to 15 parts of calcium oxide, and the solution is PH12 to PH13. Since it has high solubility, it has good solubility in water, is more soluble in water than ever before at low temperatures, and can be used for enhancing calcium in foods and improving shelf life and improving physical properties of meat. Moreover, since calcium hydroxide is easily dissolved without changing the overall physical properties of calcium hydroxide, it can be used in the same manner as before. Furthermore, the product of the present invention can be easily obtained by a very simple manufacturing method, and can be provided at low cost.
本発明の高溶解性の水酸化カルシウム溶液が製造される方法について説明する。予めブドウ糖を始めとする単独の糖又は混合した糖類を用意して置くと共にその糖類としては、単糖，二糖，糖アルコール等を単独で使っても良く、混合して使っても良い。この時、前記二糖として砂糖（ショ糖）を、糖アルコールとしてキシリトールを用いるのが好ましい。また原料の焼成カルシウムを用意して置く。この焼成カルシウムとしては、帆立貝やカキ等の貝殻焼成，ウニ殻焼成，骨焼成，造礁サンゴ焼成，卵殻焼成，乳清焼成などを用いると良い。 A method for producing the highly soluble calcium hydroxide solution of the present invention will be described. A single saccharide such as glucose or a mixed saccharide is prepared in advance, and as the saccharide, a monosaccharide, a disaccharide, a sugar alcohol, or the like may be used alone, or a mixture may be used. At this time, it is preferable to use sugar (sucrose) as the disaccharide and xylitol as the sugar alcohol. Prepare the raw calcined calcium. As the calcined calcium, it is preferable to use scallop shell, oyster shell shell firing, sea urchin shell firing, bone firing, reef-building coral firing, eggshell firing, whey firing, and the like.
先ず始めに、単独の糖又は混合した糖類を水に溶かして糖液を作る。この時、糖液を４０〜８０℃に加熱して保温させておくと共に糖液の濃度を５〜５０％重量の範囲を保持させておく。次に上記状態の糖液を所定の大きさの容器に入れ、更に糖液中に原料の焼成カルシウムを徐々に入れながら掻き混ぜ、糖液が少しでも濁り始めたら焼成カルシウムの投入を即座に止める。この状態が焼成カルシウムの溶け込む量の飽和状態である。この時、糖溶１００部に対して焼成カルシウムが、２〜１５部前後入れられた結果となった。このように高濃度に溶解した水酸化カルシウム溶液が得られるのである。この水酸化カルシウム溶液は、ＰＨ１２〜ＰＨ１３のアルカリ性で、抗菌性があり、食肉，魚肉，野菜等の殺菌やカルシウム補給、更には食品の日保ち向上用及び食肉の物性改良用に利用できるものとなる。この「食肉の物性改良」とは、本発明に於いては肉類の切片やミンチを結着して塊状に形成することを指すものとする。また食品に於いては、硝酸塩や亜硝酸塩、リン酸塩の代用として用いることができ、結着性を有するものとなる。 First, a single sugar or a mixed sugar is dissolved in water to make a sugar solution. At this time, the sugar solution is heated to 40 to 80 ° C. and kept warm, and the concentration of the sugar solution is kept in the range of 5 to 50% by weight. Next, put the sugar solution in the above state into a container of a predetermined size, and stir it while gradually adding the raw calcined calcium into the sugar solution. If the sugar solution starts to become cloudy, stop adding calcined calcium immediately. . This state is a saturated state in which the calcined calcium is dissolved. At this time, about 2 to 15 parts of calcined calcium was added to 100 parts of sugar solution. Thus, a calcium hydroxide solution dissolved at a high concentration is obtained. This calcium hydroxide solution is alkaline and has an antibacterial property of PH12 to PH13, and can be used for sterilization of meat, fish meat, vegetables, etc., calcium supplementation, and for improving food preservation and improving physical properties of meat. . The “improvement of physical properties of meat” in the present invention refers to forming a lump of meat pieces and mince together. In foods, it can be used as a substitute for nitrate, nitrite, and phosphate, and has binding properties.
尚、本発明の水酸化カルシウム溶液の製造方法としては、上記に限定されるものではなく、例えば、先に、単独の糖又は混合した糖類に、原料の焼成カルシウムを所定量入れながら掻き混ぜ、その混合された粉末を、一定量の水の中に入れながら加熱し、所定温度を保温すると共に混合された粉末が完全に溶けるまで掻き混ぜることによって、高濃度に溶解した水酸化カルシウム溶液を得るものとしても良い。 In addition, the method for producing the calcium hydroxide solution of the present invention is not limited to the above, for example, first, a single saccharide or a mixed saccharide is mixed with a predetermined amount of calcined calcium as a raw material, The mixed powder is heated while being put in a certain amount of water, kept at a predetermined temperature, and stirred until the mixed powder is completely dissolved to obtain a calcium hydroxide solution dissolved in a high concentration. It is good as a thing.
又、原料の焼成カルシウムを溶かす際、前記糖液が４０℃以下になると、溶解速度が遅くなり、溶解時間が多く掛かってしまい、生産性が低下する恐れがあった。また８０℃以上になると、反応が早過ぎて扱いにくくなり、沸騰してオーバーフローする恐れがあると共に糖液が茶色に色付いてしまう恐れが出てくる。好ましくは６０〜７０℃の範囲に糖液を保温するのが良い。一方、糖液の濃度が５％重量以下になると、焼成カルシウムの溶ける量が減り、５０％重量以上になると、糖液の粘度が上がり、原料の焼成カルシウムを入れながら掻き混ぜ作業がスムーズに行えなくなり、作業性を悪くする恐れがあった。尚、糖液の好ましい濃度としては２０〜５０％重量の範囲にするのが良い。 Further, when dissolving the calcined calcium as a raw material, if the sugar solution is 40 ° C. or lower, the dissolution rate is slowed, so that the dissolution time is increased and the productivity may be lowered. When the temperature is 80 ° C. or higher, the reaction is too early and difficult to handle, and it may boil and overflow, and the sugar solution may turn brown. Preferably, the sugar solution is kept warm in the range of 60 to 70 ° C. On the other hand, when the concentration of the sugar solution is 5% or less, the amount of calcined calcium is reduced. When the concentration is 50% or more, the viscosity of the sugar solution is increased, and the mixing operation can be smoothly performed while adding the raw material calcined calcium. There was a risk that workability would deteriorate. In addition, as a preferable density | concentration of a sugar solution, it is good to set it as the range of 20 to 50% weight.
上記製造方法によって得られた高濃度に溶解した水酸化カルシウム溶液は、一夜放置した後、公知の噴霧乾燥などによって粉末にする。このように本発明品は、焼成カルシウムを糖類で溶して得るか、或いは焼成カルシウムと糖類を始めから混合させ、水を加えて高溶解性の水酸化カルシウム溶液が得られる。この高溶解性の水酸化カルシウム溶液は、従来の水酸化カルシウムの物性全般を変えることなく、水に水酸化カルシウムを多く溶け込ませることが可能となった。つまり、高溶解性の水酸化カルシウムが得られるに至った。 The calcium hydroxide solution dissolved in a high concentration obtained by the above production method is allowed to stand overnight and then powdered by known spray drying or the like. Thus, the product of the present invention can be obtained by dissolving calcined calcium with saccharides, or by mixing calcined calcium and saccharides from the beginning and adding water to obtain a highly soluble calcium hydroxide solution. This highly soluble calcium hydroxide solution can dissolve a large amount of calcium hydroxide in water without changing the overall physical properties of conventional calcium hydroxide. That is, highly soluble calcium hydroxide was obtained.
次に本発明品を粉末にする場合について説明する。先ず始めに水６０Ｌを用意しておき、その中にショ糖４０Kgを加えて加熱し、完全にショ糖を溶け込ませた後、沸騰させて脱炭酸し、それを６０℃になるまで冷却させる。そして、この６０℃の糖液中に帆立貝殻焼成カルシウムを徐々に入れ、糖液が濁り始める直前まで入れ続ける。この帆立貝殻焼成カルシウムは６．０Kg溶け込んだ。この溶液を一夜放置した後、上澄み液を取出す。この時、前記溶液はアルカリ性であるため、液中に含有する炭酸ガスによって多少炭酸カルシウムが生じて沈殿する。尚、前記脱炭酸させておくことにより、炭酸カルシウムの沈殿量を減少させることができるものとなる。次に取出した上澄み液を公知の噴霧乾燥によって粉末にする。この乾燥物は３３．５Kg得られ、水分５．６％、Ｃａ１０．５％であった。 Next, the case where the product of the present invention is powdered will be described. First, 60 L of water is prepared, and 40 kg of sucrose is added and heated therein. After the sucrose is completely dissolved, it is boiled and decarboxylated, and then cooled to 60 ° C. Then, the scallop shell calcined calcium is gradually put into the 60 ° C. sugar solution, and kept until just before the sugar solution starts to become cloudy. This scallop shell calcined calcium dissolved 6.0 kg. After leaving this solution overnight, the supernatant is removed. At this time, since the solution is alkaline, some calcium carbonate is generated and precipitated by the carbon dioxide contained in the solution. Note that the amount of precipitated calcium carbonate can be reduced by decarboxylation. Next, the taken-out supernatant liquid is powdered by well-known spray drying. As a result, 33.5 kg of the dried product was obtained, and the water content was 5.6% and Ca was 10.5%.
また本発明品を粉末にする他の場合について説明する。先ず始めに水６０Ｌを用意しておき、その中にショ糖３２Kgとキシリトール２２Kgを加えて加熱し、完全にショ糖とキシリトールを溶け込ませた後、沸騰させて脱炭酸し、それを６０℃になるまで冷却させる。そして、この６０℃の糖液中に帆立貝殻焼成カルシウムを徐々に入れ、糖液が濁り始める直前まで入れ続ける。この帆立貝殻焼成カルシウムは１０Kg溶け込んだ。この溶液を一夜放置した後、上澄み液を取出す。次に上澄み液を公知の噴霧乾燥によって粉末にする。この乾燥物は４０．０Kg得られ、水分９．５％、Ｃａ１２．５％であった。 Further, another case where the product of the present invention is powdered will be described. First, 60 L of water is prepared, 32 kg of sucrose and 22 kg of sucrose are added and heated, and after sucrose and xylitol are completely dissolved, it is boiled and decarboxylated, and it is heated to 60 ° C. Allow to cool until Then, the scallop shell calcined calcium is gradually put into the 60 ° C. sugar solution, and kept until just before the sugar solution starts to become cloudy. This scallop shell calcined calcium dissolved 10 kg. After leaving this solution overnight, the supernatant is removed. The supernatant is then powdered by known spray drying. 40.0 kg of this dried product was obtained, and the water content was 9.5% and Ca was 12.5%.
次に高溶解性の水酸化カルシウム溶液の水に対する溶解性について説明する。この水酸化カルシウムの溶解性は、図１に示す酸化カルシウムの溶解性と略同じ傾向を示す。先ず始めに上記要領で下記のサンプルを作る。このサンプルはショ糖を溶かして濃度が５％重量の糖液を８０℃に加熱した中に、帆立貝殻焼成カルシウムを溶け込ませ、得られた水酸化カルシウム溶液の上澄み液を公知の噴霧乾燥によって粉末にする。この粉末は、水分６．０％、Ｃａ２７．０％である。これをサンプル１とする。尚、サンプル１は、４０℃よりも８０℃の方が溶解量は少ないので、８０℃の方をサンプルとした。 Next, the solubility of a highly soluble calcium hydroxide solution in water will be described. The solubility of this calcium hydroxide shows the same tendency as the solubility of calcium oxide shown in FIG. First of all, make the following sample as described above. This sample is prepared by dissolving sucrose and heating a scallop shell calcined calcium while heating a sugar solution having a concentration of 5% by weight to 80 ° C., and powdering the supernatant of the obtained calcium hydroxide solution by known spray drying. To. This powder has a moisture content of 6.0% and Ca of 27.0%. This is designated as sample 1. In addition, since the dissolution amount of the sample 1 is less at 80 ° C. than at 40 ° C., the sample at 80 ° C. was used.
サンプル２としては、ショ糖を溶かして濃度が２０％重量の糖液を４０℃に加熱した中に、帆立貝殻焼成カルシウムを溶け込ませ、得られた水酸化カルシウム溶液の上澄み液を公知の噴霧乾燥によって粉末にする。この粉末は、水分５．６％、Ｃａ１０．５％である。 As sample 2, scallop shell calcined calcium is dissolved in sucrose dissolved in a sugar solution having a concentration of 20% by weight and heated to 40 ° C., and the obtained calcium hydroxide solution supernatant is spray-dried.

To powder. This powder has a moisture content of 6.5% and Ca of 12.0%.
次に水２０℃で１００mlに対して、サンプル１〜５を溶解すると共にそれが濁り始める直前までに溶けた水酸化カルシウムの溶解量を計測した。尚、普通の水酸化カルシウムの溶解量は、０．１６１ｇであるが、結果は下記のようになった。つまり、サンプル１は０．９５ｇであり、サンプル２は５．８５ｇであり、サンプル３は６．７２ｇであり、サンプル４は１０．６２ｇであり、サンプル５は１２．４０ｇであった。従って、サンプル１は従来よりも５．９０倍溶け込み、サンプル２は従来よりも３６．３倍溶け込み、サンプル３は従来よりも４１．７倍溶け込み、サンプル４は従来よりも６５．９倍溶け込み、サンプル５は従来よりも７７．０倍溶け込み、高溶解性の水酸化カルシウム溶液になったことが確認された。 Next, the dissolved amount of calcium hydroxide dissolved immediately before the samples 1 to 5 were dissolved in 100 ml of water at 20 ° C. and immediately before becoming cloudy was measured. The amount of ordinary calcium hydroxide dissolved was 0.161 g, and the results were as follows. That is, sample 1 was 0.95 g, sample 2 was 5.85 g, sample 3 was 6.72 g, sample 4 was 10.62 g, and sample 5 was 12.40 g. Therefore, sample 1 is 5.90 times more soluble than before, sample 2 is 36.3 times more soluble than conventional, sample 3 is 41.7 times more soluble than conventional, sample 4 is 65.9 times more soluble than conventional, It was confirmed that Sample 5 was 77.0 times more soluble than before and became a highly soluble calcium hydroxide solution.
図１は砂糖の濃度と温度に於ける酸化カルシウム（焼成カルシウム）の溶解量の変化を示すグラフであると共に同じ濃度の糖液であっても単独の糖と混合した糖類の場合の違い、及び単独の糖と混合した糖類との相違、更には一般の酸化カルシウムの溶解量を示すグラフである。また図２は酸化カルシウムの糖液に対する溶解量を２０℃，４０℃，８０℃で且つ濃度５％重量，１０％重量，２０％重量，３５％重量，５０％重量の組合せによる変化、及び一般の酸化カルシウムの溶解量が温度による影響を示した表である。 FIG. 1 is a graph showing changes in the dissolved amount of calcium oxide (calcined calcium) at the sugar concentration and temperature, and the difference in the case of a saccharide mixed with a single sugar even in a sugar solution of the same concentration; It is a graph which shows the difference with the saccharide | sugar mixed with the single saccharide | sugar, and also the dissolved amount of general calcium oxide. FIG. 2 also shows changes in the amount of calcium oxide dissolved in the sugar solution depending on the combination of 20 ° C., 40 ° C. and 80 ° C. and concentrations of 5%, 10%, 20%, 35% and 50%. It is the table | surface which showed the influence by the temperature of the dissolution amount of calcium oxide.
この結果、得られた本発明品は、濃度十数％重量以上（図中の３〜６）の糖液に対する酸化カルシウムの溶解量が２０℃，４０℃，８０℃と高くなるに従って増加し、且つ糖液の濃度５％重量，１０％重量，２０％重量，３５％重量，５０％重量と高くなるに従って増加することが確認された。更に単独の糖を使用するよりも混合した糖類を使用する方が、酸化カルシウムの溶解量が増加することを本発明者によって確認した。尚、一般の酸化カルシウムの溶解量は、温度が高くなるに従って微量に減少するが、温度による影響は殆んど受けず、難溶性である。また濃度十数％重量以下（図中の１と２）の糖液に対する酸化カルシウムの溶解量は、一般の酸化カルシウムの溶解量の傾向と同じように温度が高くなるに従って減少する傾向を示した。 As a result, the obtained product of the present invention increases as the amount of calcium oxide dissolved in the sugar solution having a concentration of 10% by weight or more (3 to 6 in the figure) increases to 20 ° C, 40 ° C, 80 ° C, Further, it was confirmed that the concentration of the sugar solution increased as it increased to 5%, 10%, 20%, 35%, and 50%. Furthermore, the present inventors have confirmed that the amount of calcium oxide dissolved is increased by using a mixed saccharide rather than using a single saccharide. In addition, although the amount of dissolution of general calcium oxide decreases slightly as the temperature increases, it is hardly affected by the temperature and hardly soluble. In addition, the dissolved amount of calcium oxide in the sugar solution having a concentration of 10% by weight or less (1 and 2 in the figure) showed a tendency to decrease as the temperature increased, in the same manner as the general dissolved amount of calcium oxide. .
尚、本発明品を得るに当り、各種の単糖，二糖，糖アルコールを用いて糖液を作り、酸化カルシウム（焼成カルシウム）の溶解量の変化が、糖液の濃度と温度の組合せによる影響の差が出るか実験したが、略上記と同様な結果となり、大差はなかった。更に原料として、各種の焼成カルシウムを用いて溶解具合を実験したが、略上記と同様な結果となり、原料の相違による変化は殆んどなかった。更に粉末化したものを使用する場合と、水酸化カルシウム溶液を使用した場合との違いも殆んど生じなかった。 In obtaining the product of the present invention, a sugar solution is prepared using various monosaccharides, disaccharides, and sugar alcohols, and the change in the dissolved amount of calcium oxide (calcined calcium) depends on the combination of concentration and temperature of the sugar solution. Although an experiment was conducted to see if there was a difference in influence, the results were almost the same as above, and there was no significant difference. Furthermore, various kinds of calcined calcium were used as raw materials, and the dissolution conditions were tested. The results were substantially the same as described above, and there was little change due to differences in the raw materials. Furthermore, there was almost no difference between the case where the powdered product was used and the case where the calcium hydroxide solution was used.
次に本発明品の殺菌作用について説明する。先ず始めに高溶解性の水酸化カルシウム溶液から得られた粉末を、１００ｇの鶏砂肝に対してその表面全体に塗したもの、ミンチボールの表面全体に前記粉末を塗したもの、始めの状態の鶏砂肝とミンチボールとをそれぞれ１０個ずつ用意する。それらを１０℃で３日間保管して一般細菌の数を数えた。粉末を塗した鶏砂肝とミンチボールは、一般細菌２０００〜４０００個／ｇであり、始めの状態の鶏砂肝とミンチボールにいた数と殆んど変らず、一般細菌の増殖がなかった。一方、無添加の鶏砂肝とミンチボールは５００万〜６００万個／ｇ前後であった。従って、本発明品には殺菌効果があることを確認することが出来た。尚、高溶解性の水酸化カルシウム溶液の中に、鶏砂肝とミンチボールを浸した後、上記同様に１０℃で３日間保管して一般細菌の数を数えたが、略同数であり、殺菌効果が高溶解性の水酸化カルシウム溶液にもあることを確認するに至った。又、種々な実験を行った結果、Ｃａ量を食肉や魚肉などの食品に対して、０．１〜２．０％重量で塗すか或いは溶液に浸すのが良く、好ましくは１．５％重量以下が良い。この時、２．０％重量以上になると、肉の味が変化し、苦くなり易く、且つ固くなる恐れが生じる。 Next, the bactericidal action of the product of the present invention will be described. First, a powder obtained from a highly soluble calcium hydroxide solution was applied to 100 g of chicken sand liver on the entire surface, the powder was applied to the entire surface of a minced ball, and the initial state Prepare 10 chicken gizzards and 10 mince balls. They were stored at 10 ° C. for 3 days to count the number of general bacteria. The chicken sand liver and minced balls coated with powder were 2000 to 4000 bacteria / g of general bacteria, the number of chicken sand livers and minced balls in the initial state was almost the same, and there was no growth of general bacteria. . On the other hand, the additive-free chicken gizzards and minced balls were around 5 to 6 million pieces / g. Therefore, it was confirmed that the product of the present invention has a bactericidal effect. In addition, after immersing chicken sand liver and minced balls in a highly soluble calcium hydroxide solution, the number of general bacteria was counted by storing at 10 ° C. for 3 days in the same manner as described above. It came to confirm that there exists a bactericidal effect also in a highly soluble calcium hydroxide solution. In addition, as a result of various experiments, the Ca amount is preferably 0.1 to 2.0% by weight or immersed in a solution, preferably 1.5% by weight, with respect to food such as meat and fish meat. The following is good. At this time, if the weight is 2.0% or more, the taste of the meat changes, and it tends to become bitter and hard.
次に本発明品を食肉の物性改良用として利用する際は、例えば、豚のコマ肉３００ｇに本発明のカルシウム１．５ｇ（０．５％重量）を入れ良く混ぜ、ハム状に型成させ、５℃で１日保管して置くことにより、ハム状の塊を作ることが出来た。それを切って見たところ、普通の塊の肉を切ったものと同様にきれいな切断面が得られた。それをフライパンで焼いて確認したところ、肉の塊は一般の結着していないものと同じように、分離することなく調理することができた。 Next, when the product of the present invention is used to improve the physical properties of meat, for example, 300 g of pork top meat is mixed with 1.5 g (0.5% by weight) of the calcium of the present invention and mixed into a ham shape. A ham-like lump could be made by storing at 5 ° C. for 1 day. When it was cut and viewed, a clean cut surface was obtained, similar to a normal cut of meat. When it was baked in a frying pan, it was confirmed that the chunks of meat could be cooked without separation in the same way as ordinary unbound pieces.
又、本発明品をソーセージに混ぜて作る。この時、ソーセージに本発明品を混ぜて、０．２〜１．０％重量Ｃａが入れられた状態にすることにより、弾力性が良くなり、且つ、色合いが鮮明なピンク色になり、更に歩留まりが５〜１０％向上するものとなった。この歩留まりが向上する主な要因は、水分がその分増えるためと考えられる。 The product of the present invention is mixed with sausage. At this time, the product of the present invention is mixed with sausage and 0.2 to 1.0% by weight of Ca is put in, so that the elasticity is improved and the hue becomes a clear pink color. The yield was improved by 5 to 10%. It is considered that the main factor for improving the yield is that the moisture increases accordingly.
このように本発明品には抗菌性・殺菌性があり、食品を日持ちさせることが可能になり、且つ、水に溶け易くなることにより、カルシウムの強化剤やＰＨ調整剤及び食肉の物性改良用として利用することが可能なものとなるため、広い用途が期待できる食材となるのである。 As described above, the product of the present invention has antibacterial and bactericidal properties, can keep food for a long time, and can be easily dissolved in water, thereby improving the physical properties of calcium fortifier, pH adjuster and meat. Since it can be used as a food, it is a food that can be expected to be used widely.
