Technical Field

The invention belongs to the field of special functional foods, and particularly relates to a preparation method of single silkworm chrysalis peptide powder.

Background

Silkworm pupa is a stage in the life cycle of silkworm development, in this stage, the in vivo sex hormone precursor is continuously accumulated, and after a certain period of time, the sex hormone precursor is converted into moth, after the moth breaks cocoon, the male moth of female moth can be mated, and can be dead after egg laying, and the egg can be hatched into silkworm larva, and can be continuously developed until the silkworm is spinned into silkworm pupa, so that the life cycle can be completed. The silkworm chrysalis is rich in nutrition, delicious in dish taste, and the protein content of the silkworm chrysalis is more than 50%, wherein the content of 8 essential amino acids in a human body is high and is about 4 times of that of eggs. The fat content is about 29%, and the fat is mainly unsaturated fatty acid (the content is more than 80%). Also contains vitamin A, vitamin B2, vitamin D ergosterol, etc. Different substances exist in female and male silkworm chrysalis respectively to promote the female and male silkworm chrysalis to continue to develop, and the substances have universality in the animal world, such as sterol substances, which can be effectively converted into hormones, hormones and the like required by development or physiological functions, which have special biological significance for human beings, especially because the years of age increase, sex hormone secretion in adults is gradually reduced after adolescence, and various corresponding symptoms occur, such as menoxenia caused by climacteric syndrome sexual function weakening. The silkworm pupa peptide powder provides raw materials (such as solid beverage, cookies, wine, tablet candy and the like) for various functional foods, provides rich nutrition for human bodies, and improves the problems.
