Walnut powder products belong to solid drinks. High-quality walnut powder is made from high-quality walnut kernel, white sugar and whole milk powder by soaking walnut kernel, pulverizing, separating pulp and residue (removing bitter brown skin), deodorizing, blending, homogenizing, concentrating and sterilizing, and spray drying.

Walnut can be called the "king" of oxidation resistance and has high nutritional value. The American Dietetic Association advises people to eat walnuts two or three times a week, especially middle-aged and elderly people and menopausal women, because the arginine, oleic acid and antioxidants contained in walnuts are quite beneficial to protect the cardiovascular system and prevent coronary heart disease, stroke and Alzheimer's disease.
