Abstract

Black soldier fly larvae (BSFL) is one of the most popular edible insects authorized for feed and an excellent bioconversor of agri-food by-products. Thus, the ability of BSFL to valorize by-products from olive oil production (olive leaves, OL, or full-fat dry olive pomace, OP) and quinoa husk (QH) is explored.

OL up to 15 %, and OP or QH up to 50 %, allowed successful bioconversion of by-products, with larvae performance comparable to control. These levels did not affect protein, lipid or ash content, though chitin increased. Mainly OP feeding resulted in more unsaturated lipids of BSFL, with lauric acid decreasing from 43 % in control larvae to 23 % in OP50 and 2.5 % in OP90, while oleic acid rose as the major one to 32 % and 55 %, respectively. However, higher inclusion of OL (>15 %) and OP (>50 %) reduced protein and ash contents, increasing lipids and chitin. QH-fed larvae showed similar composition to control. Correlation analysis suggested that unbalanced diets at high levels of OL and OP influenced the results. Diets rich in carbohydrates and proteins also correlated with the saturated profile of BSFL, while high lipids and fiber led to more unsaturated ones, particularly with OP.

Therefore, BSFL can successfully valorise olive-oil and quinoa by-products when used at limited levels, maintaining similar nutritive composition of the larvae but improving their fatty acid profile.

黑虻幼虫（Hermetia illucens）饲养在传统和新兴的农业食品副产品：橄榄叶，橄榄渣和藜麦壳的情况下

黑兵蝇幼虫（BSFL）是最受欢迎的饲料食用昆虫之一，也是农业食品副产品的优秀生物转化者。因此，BSFL对橄榄油生产（橄榄叶，OL，或全脂干橄榄渣，OP）和藜麦壳（QH）的副产品的增殖能力进行了探索。OL可达15%，OP或QH可达50%，可使副产品成功生物转化，幼虫的性能与对照相当。这些水平不影响蛋白质、脂质或灰分含量，但几丁质增加了。OP50和OP90的月桂酸含量分别从对照的43%下降到23%和2.5%，而油酸含量分别上升到32%和55%。然而，较高的油（> 15%）和油（> 50%）含量降低了蛋白质和灰分含量，增加了脂质和几丁质的含量。qh喂养的幼虫组成与对照相似。相关分析表明，高水平OL和OP的不平衡饮食对结果有影响。富含碳水化合物和蛋白质的饲料也与BSFL的饱和曲线相关，而高脂和高纤维导致更多的不饱和曲线，特别是与大豆有关。因此，BSFL在有限水平下可以成功地使橄榄油和藜麦副产品的价值增加，保持幼虫的营养成分相似，但改善它们的脂肪酸曲线。
