Description

High-calcium milk and preparation method thereof
Technical Field
The invention relates to high-calcium milk and a preparation method thereof, belonging to the technical field of dairy product preparation.
Background
In recent years, with the development of socioeconomic, the living standard of people is gradually improved, and the health cognition and the demand are gradually enhanced. The milk as a health food has comprehensive nutrition, natural raw materials and rich taste. The milk contains milk raw materials which have various nutritional functional components such as milk calcium, milk protein, milk fat and the like, and can be absorbed and utilized by human bodies to improve the health level of the human bodies.
Calcium is one of essential nutrients for human body, can control heart rate and blood pressure, and participates in muscular contraction. Calcium deficiency in human body may cause rickets, night sweat, tetany, osteoporosis, cardiovascular diseases, etc. According to investigation, Chinese people are generally lack of calcium, and the biggest concern about functions in dairy product consumption is calcium supplement.
At present, the calcium content of the common commercial high-calcium milk product per 100mL is more than 120-130mg, and the calcium content of the common milk is 100-110 mg. According to the national food nutrition label regulation, the high-calcium milk can be prepared as long as the calcium content of each 100mL of dairy product is higher than 120 mg. Many high calcium milk products have a calcium content that differs by less than 25% from normal whole milk. In addition, calcium carbonate is used in most of the commercially available high-calcium milk products, and the high-calcium technology is the same as that of the commercially available high-calcium milk products, and exogenous calcium is directly added. The product with calcium content higher than 130mg has common diseases with poor taste. The products using calcium carbonate as a calcium source are divided into two products, one product does not use an additional stabilizing system, and the products have serious calcium carbonate precipitation phenomenon; the product has less natural degree owing to more compounding material. In addition, in some products using milk calcium or milk mineral salts as calcium source, too high an amount of calcium source added will affect the ionization balance of the product, resulting in deterioration of the stability of the product.
