Abstract

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.

혈당 조절에 도움을 줄 수 있는 건강기능식품 기능성 원료로 인증을 받은 동결건조 누에분말의 일반 성분 및 영양 성분에 대하여 보고된 바를 고찰하여 다음과 같은 결론을 얻을 수 있었다. 1. 동결건조 누에분말의 일반 성분은 조단백질 57.7%, 조지방 9.5%, 조섬유 5.4%, 회분 9.3%, 수분 4.7% 내외였다. 식육성 재료나 식용 곤충에 비하여 단백질 성분이 높고 지방 성분은 낮았다. 2. 동결건조 누에분말을 이루고 있는 주요 아미노산은 glutamic acid와 aspartic acid로 아미노산의 조성은 누에의 성장 단계에 따른 차이가 있었다. 3. 동결건조 누에분말은 포화지방산과 불포화지방산이 약 3:7의 비율로 있으며, linolenic acid 34.7%, oleic acid 24.4%, palmitic acid 20.2%, stearic acid 9.2%, linoleic acid 7.7%가 많이 포함되어 있다. 4. 동결건조 누에분말에 많이 포함되어 있는 5대 무기물은 칼륨, 인, 칼슘, 마그네숨, 황 등이 있으며, 그 외에도 구리, 망간, 아연, 철 등의 무기물을 가지고 있다.
