Nowadays, the mass production of insects is promoted not only for their nutritional value, but also for their ability to convert agri-food by-products into high valuable derived products. In the present work, the potential production of carotenoid-rich larvae of black soldier fly, Hermetia illucens (BSFL), was evaluated by rearing them on different agri-food by-products. The carotenoid concentration in BSFL was highly correlated with the carotenoid content of the substrates (R=0.882). Among the different substrates, tomato and carrot by-products allowed to obtain BSFL with a total carotenoid content 230% higher than the amount detected in the BSFL grown in the control diet. Furthermore, the killing method played a key role in the preservation of the BSFL carotenoid content, with dry heating resulting in a significantly higher total carotenoid content compared to blanching and freezing. These results clearly support the valorisation of agri-food by-products for the production of BSFL naturally rich in carotenoids for specific feed and food purposes.

Abstract

Nowadays, the mass production of insects is promoted not only for their nutritional value, but also for their ability to convert agri-food by-products into high valuable derived products. In the present work, the potential production of carotenoid-rich larvae of black soldier fly, Hermetia illucens (BSFL), was evaluated by rearing them on different agri-food by-products. The carotenoid concentration in BSFL was highly correlated with the carotenoid content of the substrates (R=0.882). Among the different substrates, tomato and carrot by-products allowed to obtain BSFL with a total carotenoid content 230% higher than the amount detected in the BSFL grown in the control diet. Furthermore, the killing method played a key role in the preservation of the BSFL carotenoid content, with dry heating resulting in a significantly higher total carotenoid content compared to blanching and freezing. These results clearly support the valorisation of agri-food by-products for the production of BSFL naturally rich in carotenoids for specific feed and food purposes.
