Method for producing instant calcium caseinate from food-grade casein

Abstract

The invention relates to a method for producing instant calcium caseinate from food-grade casein. The instant calcium caseinate with high content of calcium is produced by treating the food-grade casein which is used as the raw material, adding an emulsifier and drying. The method comprises the following steps: (1) dissolving: preparing the raw material which is the food-grade casein into a solution with the mass concentration of 4-10%, adding the food-grade aqueous ammonia slowly to adjust the pH value to 5.5-8.0, and stirring continuously to dissolve the casein; (2) converting: preparing the calcium hydroxide powder into a suspension, and adding the suspension into the solution of the dissolved casein, wherein the mass of the calcium hydroxide powder is 1.5-2.5% of that of the casein; (3) emulsifying: adding water-soluble soya bean lecithin after converting, and mixing uniformly; (4) grinding by using a colloid; (5) sterilizing; (6) homogenizing by using a homogenizer with the homogenizing pressure of 20-30Mpa; and (7) drying by spraying to obtain the finished product which is the instant calcium caseinate. The instant calcium caseinate has a pure color, good solubility and high content of protein and calcium, thereby being a good protein and calcium supplement.

Description

technical field

[0001] The invention relates to a method for producing calcium caseinate by using food-grade casein as a raw material, and belongs to the technical field of dairy products and food additives. Background technique

[0002] Calcium caseinate, also known as calcium caseinate, has excellent properties such as emulsification, stability and easy film formation, and is widely used in the food industry. It is also widely used in sports nutrition as a good source of protein and calcium. Food and nutritionally fortified food. In addition, calcium caseinate can also be used in papermaking, leather and latex industries.

[0003] At present, the raw materials for the production of calcium caseinate are mainly milk, casein and koji. The cost of producing calcium caseinate with milk as raw material is relatively high, and the production of calcium caseinate with koji as raw material is difficult to control because the production areas of koji are scattered and the quality...

Embodiment 1

[0026] a) Dissolution: Add 1600L of water to a 2000L heatable dissolving tank, then add 80kg of food-grade casein, heat up the casein solution while adding water to make the temperature of the casein solution 40°C, slowly add food-grade ammonia water into the dissolving tank, and keep stirring at the same time , so that the casein is slowly dissolved, and after it is completely dissolved, the pH value of the solution is maintained at 6.0;

[0027] b) Transformation: prepare 1.2kg of powdered calcium hydroxide into a suspension, add it into the dissolved casein solution, and keep it warm at 40°C for 2 hours, so that the casein and calcium hydroxide are fully combined;

[0028] c) emulsification: dissolve 0.08 kg of water-soluble phospholipids, add after the casein and calcium hydroxide have fully reacted, and mix well;
