Black soldier fly (Hermetia illucens) larvae (BSFL) is rapidly becoming a new sustainable ingredient. Currently, there is no information on purging BSFL and consequently their nutritional profile. In the first part of this study, the BSFL urea/ammonia content along with proximate, fatty acid and amino acids were examined when food was withdrawn at 0, 3, 6, 9, 12 and 24 h. After 3 h, urea content linearly increased until 24 h, while ammonia also increased linearly, but then decreased by 24 h. Total amino acids and total fatty acids gradually decreased and increased over time, respectively. At 3 and 6 h, butyric and acetic acid significantly decreased, respectively. In a follow-up separate study, providing coconut fibers mitigated the ammonia/urea increases within 48 h. Results indicate that the nutritional profile of BSFL reduces over time and thus should be processed immediately. Further research should explore the possibility of nutrient loading prior to harvest and more effective ways for purging BSFL.

黑士兵飞（Hermetia illucens幼虫（BSFL）迅速成为一种新的可持续成分。目前，尚无有关清除BSFL的信息，因此也没有营养信息。在本研究的第一部分中，当在0、3、6、9、12和24 h取出食物时，检查了BSFL尿素/氨含量以及附近的，脂肪酸和氨基酸。3小时后，尿素含量线性增加直至24小时，而氨气也线性增加，但随后减少24小时。总氨基酸和总脂肪酸分别随时间逐渐减少和增加。在3和6小时，丁酸和乙酸分别显着降低。在一项后续的单独研究中，提供椰子纤维可在48小时内缓解氨/尿素的增加。结果表明，BSFL的营养成分会随着时间的流逝而减少，因此应立即进行处理。
