Abstract

The invention belongs to the technical field of functional food and relates to calcium-rich instant egg white powder and a preparation method thereof. The preparation method comprises technical processes of preparation of main materials, preparation of egg white peptide calcium chelate, blending of main and auxiliary materials, low-temperature superfine grinding and high-temperature sterilization. The auxiliary material components in the calcium-rich instant egg white powder comprise, in percentage by weight of the main materials, 4%-6% of the egg white peptide calcium chelate, 3%-5% of maltodextrin, 0.5%-5% of sucralose and 0.2%-0.5% of perfume. The calcium-rich instant egg white powder which can supplement calcium and high-quality amino acid, is instant when made, has light yellow color, tastes fine and mellow and is easy to digest by the human body is prepared while the problem of lower calcium absorption rate is solved.

Description

technical field [0001] The invention belongs to the technical field of functional foods, and in particular relates to a calcium-rich instant egg white powder and a preparation method thereof. Background technique [0002] Calcium is an essential nutrient element in the human body, accounting for about 1.5-2% of body weight. It is not only an important structural tissue component in the human body, but also participates in the regulation of various physiological processes of cells, such as muscle contraction, blood coagulation, nerve conduction, enzyme activation, hormone secretion, cell growth and other physiological activities. The daily dietary calcium supply recommended by the Chinese Nutrition Society is 800 mg for adults, 600-1200 mg for children and adolescents, 1000-1500 mg for pregnant women, and 1500 mg for nursing mothers. At present, the residents of our country generally lack calcium. Insufficient calcium intake will affect the normal growth and development of c...
