Allium cepa, onion peel, by-product, biological activityAbstract
A large number of by-products are released during the processing of onions (Allium cepa), in which the peel contains many active ingredients useful in medicine. The growing consumer demand for processed foods poses the problem of reducing waste by converting it into useful products. This study highlights the main bioactive components in onion peel, especially phenols, flavonoids, quercetin, and its derivatives with cardioprotective, neuroprotective, antibacterial, and antidiabetic effects, and anti-cancer. Thereby, this study also emphasized that onion peel is one of the important agricultural by-products rich in biological activities that can be used as a health-promoting and protective ingredient.
