Preparation method of high-calcium whey beverage and product thereof

Abstract

The invention provides a preparation method of a high-calcium whey beverage and a product thereof. The preparation method comprises the following steps that whey, high-calcium protein powder, a sweetsubstance and water are prepared, wherein the high-calcium protein powder is prepared by separating and concentrating casein micellae in sequence, and the content of calcium is equal to or higher than2000 mg / 100g; the pH value of the whey is 5.6-5.8, the total amount of the finished product high-calcium whey beverage is 100%, the weight percentage of the whey is 30-91%, the weight percentage of the sweet substance is 2.5-5.3%, the weight percentage of the water is 0-61%, and the content of the high-calcium protein powder is limited by that the calcium in the high-calcium protein powder account for, by mass percentage, 120 mg / 100 ml or above of the finished product high-calcium whey beverage. During preparation, the high-calcium protein powder is evenly mixed with the sweet substance firstand then put into the whey which is preheated to 20-30 DEG C for uniform mixing; water is added to set the volume, and then cooling is quickly conducted; preheating, homogenizing, sterilizing, cooling and filling are conducted, and the finished product is obtained. The high-calcium whey beverage containing no food additives is prepared.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of a high-calcium whey beverage and its product. Background technique [0002] When cheese is produced, whey is excreted as a by-product. Due to the high requirements for whey processing equipment, and the whey protein in whey is extremely unstable when exposed to heat, and is prone to precipitation after heat treatment, etc., therefore, whey is rarely reprocessed and utilized in China. However, in recent years, consumers' awareness of cheese has been continuously improved, making cheese maintain an average annual growth rate of more than 14.5% in China. In this way, the reuse of whey and industrial production have become more and more meaningful. . [0003] Whey protein has a high level of awareness among fitness people. These people often drink whey protein powder to ensure their protein needs. However, protein powder is not convenient to drink an...

Problems solved by technology

[0006] After calcium is added, thickeners must be used to stabilize the system in order to achieve a better dissolution and suspension effect, otherwise precipitation will occur, which will lead to product defects such as calcium content test data not up to standard, and thickeners also belong to Food additives; therefore, the ingredient list of the existing high-calcium dairy product packaging usually contains food additives, which cannot meet the high health needs of consumers and affect the sales of products
