摘要

食用昆虫是供人类食用的蛋白质、脂质和矿物质的可持续来源，具有从替代饲料中转化和生物积累营养化合物的潜力。研究了利用农用工业副产物亚麻籽饼作为饲料替代品，对白纹鼢鼠幼虫进行营养富集。分别饲喂不同比例的亚麻籽饼饲料（0%、25%、50%、75%和100%），评价其营养状况和饲料效率。饲料转化效率与添加75%亚麻籽饼的对照组相当。饲喂100%亚麻籽饼的幼虫蛋白质含量高于对照组（46.68%比41.38%），脂肪酸分布显著改善，α -亚麻酸从1.03%增加到28.66%。这导致omega-6/omega-3比值从23.61降至0.58。矿物分析显示，饲喂100%亚麻籽饼的幼虫体内磷、锰、锌和镁含量较高。综上所述，亚麻籽饼可提高白腹虫幼虫的营养水平，为可持续食物系统提供更高的蛋白质含量和有益脂肪酸。

Replacing conventional substrate with linseed cake improves the omega-3 profile of Zophobas atratus fabricius (Coleoptera: Tenebrionidae) larvae

Edible insects emerge as sustainable sources of protein, lipids, and minerals for human consumption, with the potential for transformation and bioaccumulation of nutritional compounds from alternative feeds. This study examined the nutritional enrichment of Zophobas atratus larvae using linseed cake, an agro-industrial by-product, as a feed substitute. Larvae were fed diets containing varying proportions of linseed cake (0 %, 25 %, 50 %, 75 %, and 100 %), and their nutritional profile and feed efficiency were evaluated. Feed conversion efficiency remained comparable to the control group with up to 75 % linseed cake incorporation. Larvae fed 100 % linseed cake showed higher protein content (46.68 % vs. 41.38 % in control) and significantly improved fatty acid profiles, with alpha-linolenic acid increasing from 1.03 % to 28.66 %. This resulted in a favorable shift in the omega-6/omega-3 ratio from 23.61 to 0.58. Mineral analysis revealed high levels of phosphorus, manganese, zinc, and magnesium for larvae fed 100 % linseed cake. The results demonstrate that Zophobas atratus larvae can be nutritionally enhanced through linseed cake feeding, offering improved protein content and beneficial fatty acid profiles for sustainable food systems.
