Abstract

Heavy metals and residual agricultural chemicals in Bombyx mori silkworm cocoon for nontextile usages were examined. Proximate composition of silkworm cocoon was examined; contents of moisture, crude protein, crude fat, and ash were about 5 ~ 6%, 93 ~ 94%, 0.4 ~ 0.5%, and 0.3 ~ 0.4%, respectively. The Heavy metals were analyzed by ICP/MS after acid digestion. Arsenic, cadmium, and lead were not detected. The average contents of mercury, zinc, and cupric were 0.317, 3.99, and 2.06 mg/kg, respectively. Agricultural chemicals, such as dichlorvos and paraquart also were not detected. Silkworm cocoon may be safe used for nontextile applications.

비섬유용 소재로 활용될 누에고치의 중금속 함량 및 농약잔류량을 조사하였다. 농가에서 생산하는 누에고치에서 상견비율은 89.1%, 전견중은 2.11 g, 견층중은 0.4670 g으로 나타나 견층비율 22.13%인 것으로 나타났다. 누에고치의 일반 성분을 분석한 결과 조단백질은 93 ~ 94%, 수분은 5 ~ 6%, 조회분은 0.3 ~ 0.4%, 그리고 조지방은 0.4 ~ 0.5%로 나왔다. 누에고치의 중금속 분석 결과 비소, 납, 카드뮴 등은 검출되지 않았으나, 아연이 3.99 mg/kg, 수은은 0.317 mg/kg 포함되어 있었다. 농가에서 사용하는 농약 성분인 디클로르보스와 파라콰트가 검출되지 않아 식품, 화장품, 의료용 소재 등 비섬유용 소재로 활용이 가능할 것으로 사료된다.
