European legislation permits the inclusion of insect proteins in pet and aquaculture diets. Black soldier fly larvae (BSF) are one of the most actively produced species due to their low environmental impact and nutritional characteristics. BSF protein derivatives (proteins and protein hydrolysates) contain a substantial amount of low molecular weight peptides that are known to possess antioxidant potential. In this study, the in vitro antioxidant potential of commercial BSF proteins and protein hydrolysates was investigated for (1) radical scavenging activity, (2) myeloperoxidase activity modulation, and (3) neutrophil response modulation. Chickenmeal and fishmeal are commonly used in pet food and aquaculture formulations. Hence, both were used as industrial benchmarks during this study. The results indicate that fishmeal and chickenmeal are ineffective at suppressing the oxidative damage caused by neutrophil response and myeloperoxidase activity. Fishmeal and chickenmeal even exhibit pro-oxidant behavior in some of the models used during this study. On the other hand, it was found that BSF protein derivatives could be effective in protecting against the cellular damage resulting from neutrophil and myeloperoxidase activities. The outcomes of this study indicate that BSF protein derivatives could be potentially included in pet food and aquaculture feed formulations as health-promoting ingredients.

黑士兵蝇（Hermetia Illucens）幼虫蛋白衍生物：促进动物健康的潜力。

欧洲法规允许在宠物和水产养殖饮食中添加昆虫蛋白。黑战士苍蝇幼虫（BSF）由于其对环境的影响和营养特性低而成为最活跃的物种之一。BSF蛋白衍生物（蛋白和蛋白水解物）包含大量已知具有抗氧化潜力的低分子量肽。在这项研究中，对商业BSF蛋白和蛋白水解物的体外抗氧化潜力进行了研究：（1）自由基清除活性，（2）髓过氧化物酶活性调节和（3）中性粒细胞应答调节。鸡肉粉和鱼粉通常用于宠物食品和水产养殖配方中。因此，在本研究中，两者均被用作工业基准。结果表明，鱼粉和鸡肉粉不能有效抑制中性粒细胞反应和髓过氧化物酶活性引起的氧化损伤。在这项研究中使用的某些模型中，鱼粉和鸡肉粉甚至表现出促氧化行为。另一方面，发现BSF蛋白衍生物可以有效地防止由嗜中性粒细胞和髓过氧化物酶活性引起的细胞损伤。这项研究的结果表明，BSF蛋白衍生物可以作为促进健康的成分潜在地包含在宠物食品和水产养殖饲料配方中。已经发现BSF蛋白衍生物可以有效地防止由嗜中性粒细胞和髓过氧化物酶活性引起的细胞损伤。这项研究的结果表明，BSF蛋白衍生物可以作为促进健康的成分潜在地包含在宠物食品和水产养殖饲料配方中。已经发现BSF蛋白衍生物可以有效地防止由嗜中性粒细胞和髓过氧化物酶活性引起的细胞损伤。这项研究的结果表明，BSF蛋白衍生物可以作为促进健康的成分潜在地包含在宠物食品和水产养殖饲料配方中。
