Can I still drink walnut powder after it has expired 1 month?

Of course, expired food can't be eaten, otherwise it means that the nutrients have been destroyed and deteriorated, which will cause harm to the body.

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.
