식·약용으로 사용되고 있는 흰점박이꽃무지(Protaetia brevitarsis) 유충은 가공 전처리 시 배변 유도 섭식물로 찹쌀과 비지를 사용하고 있으나 생산비 절감, 영양적 가치 증대, 이취감 저감을 목적으로 가공부산물로 대체할 필요가 있다. 본 연구는 유충의 배변유도섭식물로 홍삼박, 구기자박, 흑마늘박, 마늘부산물 등을 활용하여 이에 대한 효과를 구명하고, 전처리 조건을 확립하였다. 이를 위해 섭취 한 후 배변유도, 체중 감소율, 생존율, 지표물질 등을 조사하였다. 가공부산물을 섭식한 유충의 섬유질 함량은 모든 처리구에서 무처리(절식) 9.91% 보다 낮은 섬유질 함량을 보였다. 유 충의 일별 체중 감소율과 생존율을 회귀분석하여 가공부산물 투입에 따른 사육 용기(264×194×192 mm (W×H×D)) 내 적정 마릿수를 추정한 결 과 홍삼박과 흑마늘박 섭식구가 180과 175마리로 다른 처리에 비해 높은 경향을 보였다. 유충의 살처리 및 동결건조방법에 따른 total ginsenoside, betaine, pyruvate함량은 -20°C 냉동 처리 후 동결건조한 것이 가장 높았으며, 특히 냉동 후 동결건조 처리한 홍삼박 섭식구의 total ginsenoside함 량은 다른 처리에 비해 월등히 높은 경향을 보였다. 따라서 흰점박이꽃무지 유충은 가공 전처리 시 배변 유도 섭식물로 홍삼박을 사용하여 냉동 후 동결건조하는 것이 가장 적합한 것으로 사료된다.

White-spotted flower chafer beetle (Protaetia brevitarsis) larvae, which are used for food and medicinal purposes, are customarily fed processing by-products such as glutinous rice and bean curd refuse to induce defecation during pre-treatment. This practice helps to reduce production costs, increase nutritional value, and mitigate unpleasant taste. In this study, the effects of using defecation-inducing feed materials for larvae, such as red ginseng, goji berry pomace, garlic by-products, and black garlic pomace, were investigated, and optimal pre-treatment conditions were established. To this end, we examined defecation-inducing feeding, weight loss, survival rates, and indicator substances. The fiber content of larvae fed processing by-products was 9.91% lower than that of untreated (fasting) larvae across all treatments. Using regression analysis of the daily weight loss and survival rates of larvae, we estimated the optimal number of larvae for a defecation-inducing feeding container measuring 264×194×192 mm (W×H×D) based on the processing by-product input. The number of larvae feeding on red ginseng and black garlic meals were 180 and 175, respectively. This was higher than the number of larvae in other treatment groups. The total ginsenoside, betaine, and pyruvate contents after defecation-inducing feeding, based on the larvae killing and freeze-drying methods, were highest when frozen at -20°C followed by freeze-drying. In particular, the total ginsenoside content was significantly higher in the red ginseng meal group that underwent freeze-drying after freezing compared to the other treatment groups. Therefore, it is considered most appropriate to use red ginseng meal as a defecation-inducing feed during pre-treatment, followed by freezing and freeze-drying.
