Food processing
Primary food processing turns agricultural products, such as raw wheat kernels or livestock, into something that can eventually be eaten This category includes ingredients that are produced by ancient processes such as drying, threshing, winnowing and milling grain, shelling nuts, and butchering animals for meat It also includes deboning and cutting meat, freezing and smoking fish and meat, extr
