Research progress on nutritional value and utilization of walnut
Walnut is an important economic crop with rich nutritional components,demonstrating the potential for de-veloping medicinal and edible products.This paper reviews the nutritional composition,functional characteristics,and development utilization of walnut kernels and its by-products.Walnut kernels,as the main edible part,are rich in fatty acids,proteins,carbohydrates,minerals,and vitamins,which can be used to develop products for anti-canc-er,weight loss,beauty,and more.By-products from walnut deep processing,such as diaphragma juglandis fructus,walnut green husk,and walnut leaves,contain various chemical components like juglone,polysaccharides,phenolic-s,which can be applied in developing insecticides,biomass carbons,antihypertensive drugs,among others.Fur-thermore,this paper lists several mature walnut products,such as walnut protein powder,diaphragma juglandis fruc-tus wine,and walnut oil capsules,to promote further development of China's walnut industry chain.
