Black soldier fly larvae (BSFL), Hermetia illucens (Diptera: Stratiomyidae) can reduce environmental pollution and convert organic wastes into biomass that is rich in protein and fat. The influence of the nutritional characteristics of organic waste on BSFL characteristics relevant for food and feed safety remains poorly understood. To evaluate the conversion of soybean curd residues (SCR) into high-quality animal-derived proteins and fats for human and livestock consumption, this study assessed the co-conversion efficacy, nutrient composition, safety, and anti-nutritional factor concentrations in BSFL after the development on SCR with Lactobacillus buchneri (L3-9). SCR was pretreated with L. buchneri (10 cfu/ml), and then BSFL was employed for conversion. BSFL fed with SCR and L. buchneri had a significantly higher dry mass reduction (55.7 ± 0.9%), bioconversion rate (6.9 ± 0.3%), crude protein content (55.3 ± 0.6%), and fat content (30.0 ± 0.6%) than SCR (49.0 ± 0.7%, 5.0 ± 0.3%, 52.8 ± 0.3%, and 26.1 ± 0.8%, respectively) and artificial feed (43.9 ± 0.8%, 3.9 ± 0.1%, 50.3 ± 0.4%, and 24.3 ± 0.4%, respectively). However, the feed conversion ratio (8.0 ± 0.3), of BSFL fed with SCR and L. buchneri was lower than that of the BSFL fed with SCR (9.8 ± 0.1) and artificial feed (11.1 ± 0.5). In addition, BSFL had satisfactory concentrations of all essential amino acids and fatty acids required for human consumption as recommended by WHO/FAO/UNU. The heavy metals and anti-nutritional factor concentrations were within the safety intake levels for food and feedstock. Therefore, the addition of L. buchneri with BSFL on SCR did not only increase co-conversion performance but also enhanced the nutritional value of BSFL.
黑水虻幼虫（BSFL），Hermetia illucens（双翅目：Stratiomyidae）可以减少环境污染，并将有机废物转化为富含蛋白质和脂肪的生物质。有机废物的营养特性对 BSFL 与食品安全和饲料安全相关的特性的影响仍知之甚少。为了评估豆腐渣（SCR）转化为高质量动物源性蛋白质和脂肪用于人类和牲畜消费的效果，本研究评估了在豆腐渣上与植物乳杆菌（L3-9）共同转化的效果、营养成分、安全性和 BSFL 中的抗营养因子浓度。SCR 用 L. buchneri（10 cfu/ml）预处理，然后用 BSFL 进行转化。与 SCR 和 L. buchneri 一起喂养的 BSFL 具有更高的干物质减少率（55.7±0.9%）、生物转化率（6.9±0.3%）、粗蛋白含量（55.3±0.6%）和脂肪含量（30.0±0.6%）比 SCR（49.0±0.7%、5.0±0.3%、52.8±0.3%和 26.1±0.8%）和人工饲料（43.9±0.8%、3.9±0.1%、50.3±0.4%和 24.3±0.4%）。然而，与 SCR 和 L. buchneri 一起喂养的 BSFL 的饲料转化率（8.0±0.3）低于与 SCR 一起喂养的 BSFL（9.8±0.1）和人工饲料（11.1±0.5）。此外，BSFL 含有所有必需氨基酸和世界卫生组织/粮农组织/联合国大学推荐的人类消费所需的脂肪酸，浓度均令人满意。重金属和抗营养因子浓度在食品和饲料原料的安全摄入量范围内。因此，与 BSFL 一起在 SCR 上添加 L. buchneri 不仅提高了共转化性能，还提高了 BSFL 的营养价值。
