Selenium-riched protein and selenium-riched amino acid, prepn. method and use thereof

Abstract

A Se-enriched protein and a Se-enriched amino acid are prepared from Se-enriched fresh silkworm chrysalis through drying, deoiling, extracting protein in diluted alkali solution, regulating pH value to educe Se-enriched protein, centrifugal treating, depositing, freeze drying to obtain powder, and hydrolyzing to obtain Se-enriched amino acid. They can be used to prepare food for preventing cancer.

Description

technical field

[0001] The invention relates to a selenium-enriched protein and selenium-enriched amino acid prepared from selenium-enriched silkworm chrysalis and a preparation method thereof; and a health food with selenium-enriching and cancer-preventing functions prepared from the selenium-enriched protein and selenium-enriched amino acid. Background technique

[0002] Selenium is an essential trace element for living things. Selenium has the functions of enhancing immunity, anti-aging and preventing and treating tumors in the body. Selenium deficiency leads to a decrease in the body's immune function and antioxidant capacity, and is associated with the occurrence of various diseases. Supplementing an appropriate amount of selenium can improve the body's immunity and prevent various diseases, so it has been widely valued. According to the Chinese Nutrition Society in 1988, the daily dietary selenium supply (RDA) for adults is 50 μg. However, in intervention experiments...
