High-calcium milk and production method thereof

Abstract

The invention discloses high-calcium milk and a production method thereof. The high-calcium milk is produced from the following raw material ingredients: 98.95-99.36% of raw milk, 0.46-0.58% of ionic type calcium-containing compound, 0.08-0.12% of emulsifying salt and 0.13-0.35% of a stabilizing agent. The production method of the high-calcium milk comprises the following steps: (1) dissolving an ionic type calcium-containing compound and emulsifying salt into drinking water, so as to obtain mixed liquor A; (2) mixing raw milk with a stabilizing agent, and cooling, so as to obtain mixed liquor B; (3) evaporating moisture of the mixed liquor B to obtain mixed liquor C; (4) homogenizing the mixed liquor C, carrying out UHT (ultra high temperature) sterilization, cooling to 25-30 DEG C, then slowly adding the mixed liquor A, stirring, and cooling to 2-6 DEG C, so as to obtain mixed liquor D; and (5) filling the mixed liquor D, and carrying out ultrahigh pressure treatment. The high-calcium milk disclosed by the invention adopts an ionic type calcium source and has strong stability, calcium content reaches 155-170mg / 100mL, no protein scales and a pipeline is not blocked during production, continuous production can be realized, and marketization prospect is good.

Description

technical field [0001] The invention relates to high-calcium milk and a preparation method thereof. Background technique [0002] Calcium is one of the important minerals in the human body and participates in the whole life process. Generally, calcium accounts for 1.5% to 2% of our body weight, 99% of which exists in bones and teeth, and the rest is distributed in blood and soft tissue cells. From the age of 20, the human body loses 30-50 mg of calcium every day, resulting in a loss of 1% of the total amount of bone calcium per year. When the human body is deficient, it can cause many diseases. Calcium can prevent osteoporosis and rickets, and can also prevent high blood pressure and tumors. [0003] According to the results of the Fourth National Nutrition and Health Survey (2002) released in 2005, the per capita daily calcium intake of Chinese residents is less than 391mg, which is far below the per capita intake of 800mg per day recommended by the Chinese Nutrition Soc...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defects of easy protein flocculation and scaling in ionic high-calcium dairy products in the prior art, low calcium content (generally 120mg / 100mL~150mg / 100mL), and poor product stability , provide a kind of high-calcium milk and its preparation method, the high-calcium milk prepared by the present invention adopts ionic calcium source, has strong stability, and the calcium content reaches 155mg / 100mL~170mg / 100mL, and the preparation method of the present invention also solves the problem Ionic calcium source with high calcium content. During the production of high calcium milk, protein fouling blocks the pipeline and prevents continuous production. The market prospect is good.
