Comparative Analysis of Nutritional Components and Harmful Substances of Protaetia brevitarsis Larvae Processed by Different Drying Methods
Abstract
Protaetia brevitarsis larvae are a nutrient-rich edible insect, valued for their high protein, fat, and mineral content. This study compares the nutritional composition of larvae subjected to three drying methods: hot-air drying (HAD), freeze-drying (FD), and microwave drying (MD). Moisture-adjusted analyses were conducted for proximate composition, mineral content, fatty acid profiles, and hazardous substances. The microwave-dried group (MD_PBL) exhibited significantly higher levels of crude protein (57.6 g/100g), crude fat (17.7 g/100g), and oleic acid (10.5 g/100g) compared to HAD and FD groups. In contrast, dietary fiber and calcium were most abundant in the freeze-dried samples. These results suggest that microwave drying may enhance nutrient concentration and reduce thermal degradation by rapidly removing moisture, particularly in insect tissues. Contrary to the conventional belief that freeze-drying best preserves nutrients, our findings highlight that drying efficiency depends on the structural characteristics of insect biomass and drying conditions. This study underscores the nutritional advantages of microwave drying and provides insights for optimizing processing techniques in the edible insect industry.
