Abstract

The invention discloses high-calcium milk as well as a raw material composition and a preparation method thereof. The preparation method comprises the following steps of (1) dissolving an annion calcic compound, emulsifying salt and an emulsifier into drinking water so as to obtain a reaction liquid, wherein the temperature of the reaction liquid is 40-55 DEG C; (2) raising the temperature of the milk to be 40-55 DEG C, uniformly adding the reaction liquid prepared in the step (1) into the milk, and stirring for 5-15 minutes; (3) evaporating the moisture, wherein the mass of the moisture is equal to the amount of the drinking water in the step (1); and (4) homogenizing, sterilizing and cooling so as to obtain the high-calcium milk. The high-calcium milk disclosed by the invention is good in stability, free of protein flocculation and free of protein scaling phenomenon after being produced and boiled.

Description

technical field [0001] The invention relates to high-calcium milk and its raw material composition and preparation method. Background technique [0002] Calcium is one of the most important mineral elements in the human body, 99% of which exists in bones and teeth, and the remaining 1% exists in soft tissues and body fluids. When the calcium intake of the human body is insufficient, it will cause various diseases, and even affect human health in severe cases. According to the survey, the calcium content in the daily diet of Chinese residents only reaches half of the recommended amount, and calcium deficiency is common among all kinds of people. Experts pointed out that it is a good way to adjust the dietary structure, especially to supplement the calcium content through dairy products. Therefore, fortifying calcium in milk is an effective way to solve insufficient calcium intake. [0003] At present, the national standards stipulate the sources of compounds used for calci...
