Before edible insects may be used as an alternative food, it is necessary to develop basic product forms and evaluate their characteristics. We made two basic commercial products (defatted powder and oil) from mealworm, a popular edible insect. The defatted mealworm powder possessed a sufficient amount of protein, and it had a savory taste due to plentiful free amino acids. Additionally, it had abundant minor nutrients and bioactive compounds. The physicochemical properties of mealworm oil were very similar to vegetable oil, and mealworm oil was also abundant in bioactive nutrients, especially γ-tocopherol. In addition, the predicted shelf life of mealworm oil was suitable for commercial use. Moreover, mealworm had high antioxidant and anti-inflammation activities, which may arise from functional peptides and glucosamine derivatives such as chitin and chitosan. In short, the defatted mealworm powder and mealworm oil could be successfully used as novel food ingredients.
在可食用昆虫能够用作替代食物之前，开发基本的产品形式并评估其特性很有必要。我们用黄粉虫（一种常见的可食用昆虫）制作了两种基本的商业产品（脱脂粉和油）。脱脂黄粉虫粉含有足够量的蛋白质，由于含有大量游离氨基酸，具有鲜香的味道。此外，它还富含微量营养素和生物活性化合物。黄粉虫油的理化性质与植物油非常相似，并且黄粉虫油中生物活性营养素也很丰富，尤其是γ-生育酚。此外，预测的黄粉虫油保质期适合商业用途。而且，黄粉虫具有较高的抗氧化和抗炎活性，这可能源于功能性肽以及几丁质和壳聚糖等氨基葡萄糖衍生物。简而言之，脱脂黄粉虫粉和黄粉虫油可以成功用作新型食品原料。
