Abstract

A protein powder features its ideal protein-amino acid structure mode and contains soybean protein, whey protein, stabilizer, lecithin and 9 amino acids necessary to human body. Its preparing process features use of boiling bed to spray lecithin and granulating.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a protein powder produced by using a fluidized bed spraying lecithin granulation technology and a preparation method thereof. Background technique [0002] Protein is the material basis of all life, an important component of tissue, and plays an irreplaceable role in all life activities. The amino acid composition of protein from various sources is usually different. Countries all over the world have the habit of using complementary proteins together under different cultural backgrounds. Soybean protein isolate is a protein extracted from soybean defatted soybean meal. It is particularly rich in lysine, which is lacking in cereal foods. Compared with other vegetable proteins, its protein digestibility is as high as 97%. Whey protein is one of the most nutritious natural proteins available, and each amino acid exceeds the nutritional intake recommended by the Food and Agric...
