Abstract

Black soldier fly larvae (BSFL) are a sustainable source of protein for feed but they can also be a sustainable source of some phytochemicals due to their ability to bioaccumulate them. Knowing that ergosterol in mushrooms can be chemically converted to vitamin D₂ (VD₂) under ultraviolet B (UVB) exposure, the aim was to investigate whether BSFL can bioaccumulate ergosterol and whether larvae ergosterol can be converted into VD₂ under UVB exposure.

Method

BSFL were reared on mushrooms for 2 weeks and then exposed to UVB (2.7 mW/cm²/s for up to 5 h). Ergosterol, VD₂ and vitamin D₃ (VD₃) were quantified by HPLC in mushrooms and larvae.

Main results

larvae non-exposed to UVB did not contain any detectable amount of VD₂ or VD₃. Larvae reared on mushrooms bioaccumulated ergosterol (702 ± 95 mg/Kg FW in larvae vs 444 ± 56 mg/Kg in mushrooms). Larvae reared on mushrooms and then exposed to UVB for 1 h contained high concentrations of VD₂ but also of VD₃ (46 ± 2 and 10.9 ± 0.5 mg/Kg FW, respectively).

Conclusions

BSFL can bioaccumulate ergosterol. UVB exposure of ergosterol-enriched BSFL results in VD₂ but also in VD₃ rich BSFL. The maximal VD concentration obtained in BSFL was about 23 times higher than cod liver oil, the food known to be richest in VD. These results suggest that VD-enriched BSFL could be used to supplement the nutrition of certain livestock with VD, or be valued as a functional ingredient. This procedure has been patented (PCT/EP2024/074854).

用蘑菇喂养黑兵蝇（Hermetia illucens）幼虫，然后将它们暴露在UVB中，会产生富含维生素D2和D3的幼虫

黑兵蝇幼虫（BSFL）是饲料蛋白质的可持续来源，但由于它们具有生物积累能力，它们也可以是一些植物化学物质的可持续来源。鉴于蘑菇中的麦角甾醇在紫外线B （UVB）照射下可化学转化为维生素D2 (VD2)，目的是研究BSFL是否能生物积累麦角甾醇，以及在紫外线B （UVB）照射下幼虫是否能将麦角甾醇转化为维生素D2。方法将dbsfl在蘑菇上培养2周，然后在2.7 mW/cm2/s的UVB下暴露5 h。采用高效液相色谱法测定蘑菇和幼虫体内麦角甾醇、维生素d2和维生素D3含量。主要结果未暴露于UVB的幼虫未检测到VD2或VD3的含量。用蘑菇饲养的幼虫可积累麦角甾醇（幼虫为702±95 mg/Kg FW，蘑菇为444±56 mg/Kg）。在蘑菇上饲养后，UVB照射1 h的幼虫含有高浓度的VD2和VD3（分别为46±2和10.9±0.5 mg/Kg FW）。结论sbsfl具有生物蓄积麦角甾醇的作用。UVB暴露于富含麦角甾醇的BSFL会导致VD2，但也会导致富含VD3的BSFL。在BSFL中获得的最大VD浓度约为已知VD含量最丰富的食物鱼肝油的23倍。这些结果表明，富含VD的牛肉精可作为VD家畜的营养补充，或作为一种功能性成分加以利用。该方法已获得专利（PCT/EP2024/074854）。
