Abstract

|
To verify the nutritional superiority and safety of Protaetia brevitarsis larvae fed a food source containing soybean curd cake, the nutrients and harmful substances of larvae reared only with fermented oak sawdust and a food source containing soybean curd cake were comparatively analyzed. The crude protein content was 50.0% in the larvae fed with a food source containing soybean curd cake (SCC), which was 1.1 times higher than that of the larvae fed with fermented oak sawdust (FOS) at 44.7%. Potassium, which showed the highest content among macrominerals, was 2.5 times higher in SCC (3,169.6 mg/100 g) than in FOS (1,245.9 mg/100 g). Among trace minerals, zinc showed 12.6 times higher content than FOS (8.2 mg/100 g) in SCC (103.0 mg/100 g). As a result of the analysis of harmful substances, all heavy metals met the edible insect control standards, and pathogenic micro- organisms, such as E. coli and Salmonella spp, were not detected. According to the above study, the larvae of P. brevitarsis fed soybean curd cake contain various nutrients, and safety has also been confirmed, so it is judged to be suitable for use as food.
