Abstract

Tenebrio molitor larvae (TML) are a novel food, recently approved for human consumption in Europe. Their high content of proteins and polyunsaturated fatty acids make them a healthy source of nutrients, with potential applications in cardiovascular disease prevention. Flour-based diets are the most common feed, due to their affordability in mass-rearing conditions. Nevertheless, flour inhalation can sensitize people to asthma, increasing the risk of developing respiratory allergy among professional and domestic TML breeders. Herein, with the purpose to reduce allergens, we substituted flour-based feed with commercial pellets for young rabbit breeding. The pellets reduced the dustiness during filtration, improving safety during handling operations. Our results demonstrate that pellets can be used to breed TML without affecting their mortality or development. Interestingly, TML ameliorate growth performances increasing mean weight, total phenol content and antioxidant activity respect to the flour-based diet used as a control. Finally, fat content was comparable with the control group, but n6/n3 ratio was significantly reduced. Taken together our results strongly support the substitution of flour-based feed with commercial pellets. Key Words: Tenebrio molitor; novel foods; edible insects; allergy; pellets.
用颗粒代替面粉饲料减少了粉尘,提高了黄粉虫养殖者的安全性
黄粉虫幼虫(TML)是一种新型食物,最近在欧洲被批准供人类食用。它们富含蛋白质和多不饱和脂肪酸,是健康的营养来源,在预防心血管疾病方面具有潜在的应用价值。基于面粉的饲料是最常见的饲料,因为它们在大规模饲养条件下可负担得起。然而,吸入面粉会使人对哮喘敏感,增加了专业和家庭TML育种者发生呼吸道过敏的风险。在这里,为了减少过敏原,我们用商业颗粒代替面粉饲料来饲养幼兔。颗粒减少了过滤过程中的粉尘,提高了处理操作的安全性。我们的研究结果表明,微球可以用来繁殖TML,而不会影响它们的死亡率或发育。有趣的是,与以面粉为基础的饲粮相比,TML改善了生长性能,提高了平均体重、总酚含量和抗氧化活性。脂肪含量与对照组相当,但n6/n3比值显著降低。综上所述,我们的结果强烈支持用商业颗粒替代面粉饲料。关键词:黄粉虫;新颖的食物;可食用昆虫;过敏;球团矿。
