FOOD TECHNOLOGY

Detailed explanation-1: -Foods that contain all nine essential amino acids are called complete proteins. These foods include beef, poultry, fish, eggs, dairy, soy, quinoa and buckwheat. Foods that contain some but not all the essential amino acids are called incomplete proteins.

Detailed explanation-2: -What is a complete protein? A food is considered a complete protein when it contains all nine essential amino acids, whereas an “incomplete protein” only contains a few of them.

Detailed explanation-3: -Nine amino acids-histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine-are not synthesized by mammals and are therefore dietarily essential or indispensable nutrients. These are commonly called the essential amino acids.

Detailed explanation-4: -A complete protein has the non-essential amino acids plus the nine essential amino acids that need to be eaten. An incomplete protein has only some of the nine essential amino acids.
