Development of processing technology for edible mature silkworm

To increase the income of sericultural farms and expand sericulture industry, new high value-added products of sericulture which are beyond current products like 5th instar 3 day dried silkworm, male pupa and silkworm dongchunghacho are needed. For this sericulture product diversification, it is in desperate need of the edible processing method after 5th instar 4 day silkworm that silkgland formation is rapidly in progress during the larva periods. So far it was hard to eat because of silkgland formation in their body. So we try to boil and steam frozen-, dried-, and living-silkworm to develop low-cost edible processing methods for farmers. As the result, the silkgland of frozen and dried silkworm was not degenerated, so silkgland in their body was not edible. But in the case of living silkworm, the silkgland of mature silkworm was degenerated by boil and steam treatment, so the body and silkgland of silkworm were not only edible but also tasted good. Then the dried silkworm was easily powdered and there was no problem when it was eaten. This source technology can be widely used in the general food industry, health functional food cosmetics, pet food and so on, so it is predictable that this will contribute to increase the income of sericulture farms and expand sericultural industry.

식용섭취를 위한 숙잠의 가공기술 개발

양잠농가의 소득증대 및 산업기반 확대를 위한 새로운 형태의 고 부가가치 양잠산물 창출을 통하여 현재까지 섭취가 어려웠던 5령4일부터 숙잠기 누에의 식용화를 위한 가공기술을 개발하였다. 농민들도 쉽게 가공이 가능하도록 생누에를 열수에 침지하여 삶거나 수증기로 쪄서 익혀 본 결과 누에의 몸체와 더불어 누에체내에 들어 있는 견사선의 섭취가 가능함은 물론 맛도 좋은 것으로 나타났다. 상기 기술은 원천기술로서 향후 일반식품, 건강기능식품, 화장품, 애완동물용 사료 등으로의 광범위한 활용이 예상돼, 양잠농가 소득증대와 산업기반 확대에 큰 기여를 할 것으로 기대된다.
