Using black soldier fly larvae reared on fruits and vegetables waste as a sustainable dietary source of provitamin a carotenoids

We showed that black soldier fly larvae reared on fruits and vegetables rich in provitamin A carotenoids can accumulate significant amounts of these vitamin precursors. Using a simulated gastro-intestinal digestion model, we demonstrated ?- ?-carotene from the are as bioaccessible they were on. calculated carotenoid-rich have capacity to provide more than molecules. Remarkably, incorporation usual quantities feed could cover needs several production animals for this vitamin. Thus, our findings suggest rearing by-products or waste be sustainable strategy recycle fraction back into food chain represent new approach fight against deficiency.
