Technical Abstract: A balanced, safe diet with proteins is important to meet nutritional requirements. Proteins occur in animal as well as vegetable products in important quantities. In some countries, many people obtain much of their protein from animal products. In other regions, the major portion of dietary protein is derived from plant products. As with animal proteins, plant proteins occur in wide variety. Wheat, maize, rice, and soybean are frequent sources of plant proteins in the western diet. Recent attention has focused on many nontraditional food proteins obtained from leaves, cereals, oilseeds, and nuts. Many plant proteins are deficient in one or more of the essential amino acids. Essential amino acids are defined as those that cannot be synthesized by an organism and are only obtained from the diet. Recent advances to improve nutritional value, food safety, and sensory quality have made plant proteins popular choices for consumers interested in healthy foods.
