A waste material rich in bioactive compounds: Hazelnut waste

Abstract

Nowadays, increasing sensitivity to the environment leads to the development of sustainable agricultural policies. In this respect, it has become important to transform agricultural waste products into value-added products. Hazelnut, which has a significant trade volume worldwide, is processed into products, and some waste materials can be emerge. These waste products could transform into high added-value to food, cosmetics, and pharmaceutical industries due to possessing the bioactive compounds such as phenolics and, dietary fibre in them. This review represents the research on the bioactive compounds from the hazelnut waste, especially conducted in recently, and concentrates on its tree leaf, husk, and oil meal.
