Also known as maize (Zea mays), corn is one of the world’s most popular cereal grains. It’s the seed of a plant in the grass family, native to Central America but grown in countless varieties worldwide. Popcorn and sweet corn are popular varieties, but refined corn products are also widely consumed, frequently as ingredients in processed food. These include tortillas, tortilla chips, polenta, cornmeal, corn flour, corn syrup, and corn oil. Whole-grain corn is as healthy as any cereal grain, as it’s rich in fiber and many vitamins, minerals, and antioxidants. Corn is typically yellow but comes in a variety of other colors, such as red, orange, purple, blue, white, and black. wikipedia
Soybean meal is used in food and animal feeds, principally as a protein supplement, but also as a source of metabolizable energy. Typically 1 bushel (i.e. 60 lbs. or 27.2 kg) of soybeans yields 48 lbs. (21.8 kg) of soybean meal.Some, but not all, soybean meal is produced from the residue left after oil extraction. Removal of the oil, which is used mostly in food, but also for industrial oils, soaps and biodiesel, involves crushing and either pressing or solvent extraction. Some, but not all, soybean meal contains ground soybean hulls. Soybean meal is heat-treated during production, to denature the trypsin inhibitors of soybeans, which would otherwise interfere with protein digestion. wikipedia
The soybean or soya bean (Glycine max) is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses. Traditional unfermented food uses of soybeans include soy milk, from which tofu and tofu skin are made. Fermented soy foods include soy sauce, fermented bean paste, nattō, and tempeh. Fat-free (defatted) soybean meal is a significant and cheap source of protein for animal feeds and many packaged meals. For example, soybean products, such as textured vegetable protein (TVP), are ingredients in many meat and dairy substitutes. wikipedia
