摘要:This study was performed to evaluate the nutritional value of silkworm pupae ( Bombyx mori ) and the content of α-glucosidase inhibitor. The percentages of total protein and lipid contents by dry weight were 55.6 and 32.2%, respectively. Silkworm pupae protein had high levels of essential amino acids such as valine, methionine and phenylalanine. The contents of essential amino acids in silkworm pupae protein satisfied the FAO/WHO/UNU suggested requirements (2007). In addition, they also possessed n -3 fatty acids, especially α-linolenic acid (36.3%), as a major component. The 50% ethanol extract of silkworm pupae contained 1-deoxynojirimycin (DNJ), which is a potent α-glucosidase inhibitor. These results suggest that silkworm pupae are a new source of high quality protein, lipid, and α-glucosidase inhibitor.
