Abstract
As part of a study on insects as food, the nutritional and harmful components in the mealworm (Tenebrio molitor) were analyzed. In addition, due to a recent introduction of live Chinese mealworms in the Korean market, components between Korean and Chinese mealworms were compared. Analysis of general composition (moisture, crude protein, crude fat, crude ash, crude fiber, and carbohydrates) showed that crude protein (50.32~52.79%) was abundant in both Korean and Chinese mealworm powders, with the protein content in the Chinese mealworm powder higher than that in the Korean mealworm powder by 2.67%. The amino acid compositions were similar, but the fatty acid compositions differed in the Korean and Chinese mealworm powders. The unsaturated fatty acid contents were 76.80~80.55% of the total fatty acid content in the mealworms. The linoleic acid contents in the Korean and Chinese mealworms were $20.8{\pm}1.1%$ and $34.69{\pm}1.9%$; the linolenic acid contents were 0.47% and 1.31%; and the oleic acid contents were $51.40{\pm}0.9%$ and $40.20{\pm}1.5%$, respectively. With respect to harmful components, such as heavy metals and bacteria that cause food poisoning, bacteria such as Escherichia coli O157:H7 and Salmonella spp. were not detected in both Korean and Chinese mealworms, and the mercury content was below the standard values for common foods (Korea, 0.03 mg/kg; China, 0.08 mg/kg).
