摘要

Edible insects as additional food and/or feed source may represent one important component to solve the problem of food security for a growing human population. Especially for covering the rising demand for protein of animal origin, seven insect species currently allowed as feed constituents in the European Union are gaining more interest. However, before considering insects such as yellow mealworm larvae (Tenebrio molitor) as suitable for, e.g. human consumption, the possible presence and accumulation of contaminants must be elucidated. The present work investigates the effects of the mycotoxin zearalenone (ZEN) and its metabolites on insect larvae. Seven different diets were prepared: toxin-free control, spiked and artificially contaminated (bothcontaining approx.500 ug/kg and approx. 2000 M-g/kg of ZEN) as well as two naturally contaminated diets (600 |xg/kg and 900 ug/kg ZEN). The diets were used in a multiple-week feeding trial using T. molitor larvae as model insects. The amount of ZEN and its metabolites in the feed, larvae and the residue were measured by HPLC-MS/MS. A significantly enhanced individual larval weight was found for the insects fed on the naturally contaminated diets compared to the other feeding groups after 8 weeks of exposure. No ZEN or ZEN metabolites were detected in the T. molitor larvae after harvest. However, ZEN,

Molitor幼虫作为模型昆虫,饮食用于多周的饲养试验。通过HPLC-MS / MS测量饲料中ZEN和其代谢物的量及其代谢物。在暴露8周后,与其他喂养基团相比,发现对在天然污染的饮食中喂养的昆虫的昆虫具有显着增强的单个幼虫重量。在收获后,在T. Molitor幼虫中检测到ZEN或ZEN代谢物。然而,在残留物样品中发现ZEN,
