발효 느타리버섯재배부산물을 급이한 흰점박이꽃무지 유충의 영양성과 안전성을 검증하고자 참나무 발효톱밥으로 사육한 유충의 영양성분 과 유해물질을 비교분석하였다. 조단백질 함량은 발효 느타리버섯재배부산물을 급이한 유충(OMCB)에서 54.0%로 참나무 발효톱밥을 급이한 유 충(FOS) 47.2%보다 1.1배 많았다. 필수아미노산 중 류신은 OMCB에서 2.8%로 가장 높았고, FOS에서는 2.7%로 비슷한 수치였다. 비필수아미 노산은 OMCB에서 프롤린의 함량이 7.2%로 가장 높았고 FOS (5.6%)보다 1.3배 더 높았다. 무기질 중 칼륨은 OMCB (2771.2 mg/100 g)와 FOS (2765.0 mg/100 g)에서 비슷한 수치였고, 불포화지방산 중 올레산은 OMCB (58.2%)와 FOS (59.6%)에서 가장 높은 함량을 나타냈다. 유 해물질 분석 결과, OMCB와 FOS에서 납, 카드뮴, 비소 모두 식용곤충 중금속 기준에 적합하였고, 식중독균에 속하는 대장균과 살모넬라균은 모두 불검출되었다. 위 연구 결과에 따르면, 발효 느타리버섯재배부산물 급이 흰점박이꽃무지 유충은 단백질과 불포화지방산뿐만 아니라 다양한 영양성 분을 포함하고 있으며, 안전성 또한 검증되었으므로 식용으로 활용하기에 적합할 것으로 판단된다.

In this study, we evaluated the nutritional value and safety of Protaetia brevitarsis larvae reared on fermented oyster mushroom cultivation by-products (OMCB) by comparing their nutritional components and harmful substances with those of larvae fed fermented oak sawdust (FOS). The crude protein content of the OMCB larvae was 54.0%, which was 1.1 fold higher than that of the FOS larvae (47.2%). Among the essential amino acids, leucine was the most abundant in OMCB (2.8%), with a similar value of 2.7% in FOS. Among the non-essential amino acids, proline content was the highest in OMCB at 7.2%, which was 1.3 fold higher than that in FOS (5.6%). Potassium levels were similar in OMCB (2771.2 mg/100 g) and FOS (2765.0 mg/100 g). Oleic acid was the predominant unsaturated fatty acid, accounting for 58.2% and 59.6% in OMCB and FOS, respectively. Analysis of harmful substances confirmed that the levels of lead, cadmium, and arsenic met the safety standards for edible insects in both OMCB and FOS, whereas foodborne pathogens, such as Escherichia coli and Salmonella, were not detected. These findings indicated that P. brevitarsis larvae reared on fermented OMCB possessed elevated protein levels, unsaturated fatty acids, and a wide array of nutrients and met established safety standards. This demonstrated their potential as a viable edible resource.
