Abstract：
Edible insects with high fat and phosphorus content are a potential novel source of lecithin, however, studies on their minor lipids are limited. In this study, lecithin was extracted from black soldier fly larvae and yellow mealworm. Herein, the effects of lecithin extraction method, matrix and ultrasound pretreatment were explored based on the fatty acid composition and phospholipid profile with soy lecithin as a reference. The use of a wet matrix and ultrasound pretreatment increased the extraction efficiency of total PLs from both insects. Insect lecithin contained a considerable amount of sphingomyelin compared to soy lecithin. In insect lecithin, a total of 47 glycerophospholipid and sphingomyelin molecular species, as well as four molecular species of fatty acyl esters of hydroxy fatty acid, were detected. This study is the first comprehensive investigation of insects as a new source of lecithin with applications in food, cosmetics and in the pharmaceutical industry.
摘要：
高脂肪和磷含量的食用昆虫是卵磷脂的潜在新来源，然而,对其次要脂质的研究有限。在这项研究中,从黑兵蝇幼虫和黄粉虫中提取卵磷脂。在这里，卵磷脂提取方法的影响,基于脂肪酸组成和磷脂谱，以大豆卵磷脂为参考，探索了基质和超声预处理。使用湿基质和超声预处理提高了从两种昆虫中提取总PL的效率。与大豆卵磷脂相比，昆虫卵磷脂含有大量的鞘磷脂。在昆虫卵磷脂中，共有47种甘油磷脂和鞘磷脂分子，以及羟基脂肪酸的脂肪酰基酯的四种分子种类，被检测到。这项研究是对昆虫作为卵磷脂在食品中应用的新来源的首次全面调查，化妆品和制药行业。
