Black soldier fly larvae (BSFL) have several advantages, such as rapid growth and sustainable production. The electrospinning encapsulation shows promise for encapsulating oils, as it does not use high temperatures, preventing degradation. This study analyzed the incorporation of oil (15, 30, and 45 % w/w) from BSFL into fibers by electrospinning using zein (20 and 25 % w/v). The results demonstrated that BSFL has a predominance of lauric acid. The morphology of fibers with 25 % zein showed a ribbon shape, whereas beads were formed in fibers with 20 % zein. The infrared showed bands that indicated successful encapsulation. Thermal properties show an interaction between the oil and zein, which decreases the mass loss of generated fibers. The contact angle showed that the addition of oil influenced the increase in the hydrophobicity of the fibers. Fibers showed high encapsulation efficiency (>91 %), and antioxidants was higher in fibers with 45 % oil.
黑水虻幼虫具有多种优势，例如生长迅速且产量可持续。静电纺丝包封技术在包封油脂方面显示出前景，因为它不使用高温，可防止油脂降解。本研究分析了通过使用不同浓度（20%和25% w/v）的玉米醇溶蛋白，将不同比例（15%、30%和45% w/w）的黑水虻幼虫油脂通过静电纺丝法掺入纤维中的情况。结果表明，黑水虻幼虫油脂中月桂酸占主导。含25%玉米醇溶蛋白的纤维形态呈带状，而含20%玉米醇溶蛋白的纤维中形成了珠粒。红外光谱显示出表明成功包封的谱带。热性能表明油脂与玉米醇溶蛋白之间存在相互作用，这降低了生成纤维的质量损失。接触角表明油脂的添加影响了纤维疏水性的增加。纤维显示出高包封效率（>91%），且含45%油脂的纤维中抗氧化剂含量更高。
