Most agricultural commodities are processed in some way. Some fruits and vegetables are canned, dried or frozen. Meat animals are slaughtered, cut up, and chilled. Wheat is ground, and the flour is baked into bread. Soybeans are crushed, and the oil is made into margarine and shortening; the meal is used for livestock feed or refined for high-protein flour. Cotton is spun into thread and yarn; the yarn goes into cloth, and the cloth into shirts and dresses and sheets. Byproducts of many agricultural products yield glycerin, fatty acids, enzymes, hormones, and many.
