From peel to profit: Turning Onion waste into wealth

Sangeeta Shree & Satyam Gautam

Abstract:
Onion: waste to health inspects the nutritional and health potential benefits of onion waste parts (peels, outer layers, and root ends) that are usually discarded or thrown. These waste portions have concentrated antioxidants, specifically quercetin, along with fiber, vitamins, and minerals. There is a demonstration of how onion waste can be reused for health and other applications such as tea preparation from peel, vegetable soup, natural dyes from outer layer, hair enriching products, composting & skincare. By reusing these waste parts of onion, we can reduce environmental waste while increasing nutritional and economic benefits also make this vegetable a boon for life.
