Analysis of Nutritional Components and Harmful Substances of Protaetia brevitarsis Larvae Fed Fermented Oyster Mushroom Cultivation By-Products
Abstract
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.
