摘要

黑兵蝇（Hermetia illucens）（BSF）是一种可以用食物残渣喂养的昆虫，其幼虫粉目前已被研究用作减少鱼粉用量的饲料配料。然而，在珍珠龙胆石斑鱼（Epinephelus fuscoguttatus ߻ × Epinephelus lanceolatus ߼）的饲料中添加 BSF 的效果并不好。较高水平的 BSF 替代会引起脂肪酸代谢紊乱，导致脂肪肝，并造成肝脏氧化损伤。此外，较高水平的 BSF 替代会降低肌肉粗纤维的百分比，并显著影响肌肉中的代谢物，包括十二酸、D-赖氨酸、D-天冬氨酸和谷胱甘肽，这对改善鱼肉没有积极作用。因此，BSF 可能需要进一步加工，如脱脂，才能得到更好的利用。

Dietary application of Hermetia illucens larvae meal negatively affected the fillet quality and fatty acid metabolism of pearl gentian grouper

Black soldier fly (Hermetia illucens) (BSF) is an insect that can be fed with food waste, and its larval meal is now studied as a feed ingredient to reduce the use of fish meal. However, adding BSF into the feed of pearl gentian grouper (Epinephelus fuscoguttatus ߻ × Epinephelus lanceolatus ߼) did not give good results. Higher levels of BSF substitution caused disorders of fatty acid metabolism, leads to fatty liver, and caused oxidative damage in the liver. Also, higher levels of BSF substitution reduced percentage of thick myofibers and significantly affected 40 of metabolites, including dodecanoic acid, D-lyxose, D-aspartic acid, and glutathione in the muscle, which did no positive effect on the improvement of fish meat. Therefore, BSF may require further processing, such as degreasing, in order to be better used.

期刊介绍： The Journal of Insects as Food and Feed covers edible insects from harvesting in the wild through to industrial scale production. It publishes contributions to understanding the ecology and biology of edible insects and the factors that determine their abundance, the importance of food insects in people’s livelihoods, the value of ethno-entomological knowledge, and the role of technology transfer to assist people to utilise traditional knowledge to improve the value of insect foods in their lives. The journal aims to cover the whole chain of insect collecting or rearing to marketing edible insect products, including the development of sustainable technology, such as automation processes at affordable costs, detection, identification and mitigating of microbial contaminants, development of protocols for quality control, processing methodologies and how they affect digestibility and nutritional composition of insects, and the potential of insects to transform low value organic wastes into high protein products. At the end of the edible insect food or feed chain, marketing issues, consumer acceptance, regulation and legislation pose new research challenges. Food safety and legislation are intimately related. Consumer attitude is strongly dependent on the perceived safety. Microbial safety, toxicity due to chemical contaminants, and allergies are important issues in safety of insects as food and feed. Innovative contributions that address the multitude of aspects relevant for the utilisation of insects in increasing food and feed quality, safety and security are welcomed.
