Abstract

Background: Incorporating Tenebrio molitor larvae as ingredients in common foods is a promising strategy to encourage their consumption. To achieve this, knowing their volatile profile and the factors that may modify the profile is essential. The effect of larval feeding over volatile composition remains under-researched, for this reason; the aim of this work was to evaluate the influence of different feeding substrates on T. molitor larvae volatile profile.

Results: Volatile compounds from both substrates and crushed larvae were determined by solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) followed by untargeted data processing. The larvae fed with leaves of olive trees exhibited peak area values higher for most compounds than the other samples, indicating that feed substrates significantly affect the larvae's volatile composition. Furthermore, 20 compounds detected in both the feeding substrates and the larvae showed a direct correlation. Three of these - elemicin, myristicin, and lavender lactone - which are of plant origin, were detected for the first time in T. molitor larvae, suggesting through ingestion.

Conclusion: The feeding substrates provide both volatile compounds and their precursors. Therefore, the choice of feed for T. molitor larvae is important not only to modify their nutritional composition but also their volatile profile. © 2026 The Author(s).

农副食品对黄粉虫幼虫挥发性成分的影响。

背景：在普通食品中加入黄粉虫幼虫作为原料是一种很有前途的策略，以鼓励其消费。要做到这一点，了解它们的不稳定特征和可能改变特征的因素是至关重要的。因此，幼虫取食对挥发性成分的影响仍未得到充分研究；本研究旨在探讨不同取食基质对黄颡鱼幼虫挥发谱的影响。结果：采用固相微萃取-气相色谱-质谱联用（SPME-GC-MS）法测定了底物和粉碎幼虫的挥发性化合物，并进行了非靶向数据处理。以橄榄树叶片为食的幼虫，其挥发性成分的峰面积值高于其他样品，表明饲料基质对其挥发性成分有显著影响。此外，在取食基质和幼虫中检测到的20种化合物具有直接相关性。其中有三种植物源性物质——榄香素、肉豆蔻素和薰衣草内酯，首次在molitor幼虫中被检测到，这表明它们是通过食入的。结论：饲用底物可提供挥发性化合物及其前体。因此，选择合适的饲料不仅可以改变幼虫的营养成分，还可以改变幼虫的挥发性特征。©2026作者。约翰威利父子有限公司代表化学工业协会出版的《食品与农业科学杂志》。

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
