Freeze-dried silkworm powder has been approved as a functional ingredients for blood glucose control since 2009. Proximate and nutrient compositions of silkworm powder was summerized as bellow. Silkworm powder contained 4.7% moisture, 57.7% crude protein, 9.5% crude fat, 5.4% crude fiber, and 9.3% ash. The larval protein contained 18 known amino acid including glutamic acid and aspartic acid. Fat is composed of 3:7 ratio of saturated fatty acid to unsaturated fatty acid including various essential fatty acids. It contained 34.7 linolenic acid, 24.4% oleic acid, 20.2% palmitic acid, 9.2% stearic acid, and 7.7% linoleic acid. Five minerals, K, P, Ca, Mg, S were abundant in the silkworm powder with other minerals such as Cu, Mn, Fe, and Zn.
