Protein Determination

Proteins are amino acid polymers. In proteins twenty different types of amino acids occur naturally. Proteins are important constituents of foods for a number of different reasons. They are a major source of energy, it contains essential amino-acids which are essential to human health, but which the body cannot synthesize. Proteins are also the major structural components of many natural foods, often determining their overall texture. Typically, proteins are used as gelling agents, emulsifiers, foaming agents and thickeners. Many food proteins are enzymes which are capable of enhancing the rate of certain biochemical reactions. Therefore food analysts are interested in knowing the total concentration, type, molecular structure and functional properties of the proteins in foods (people.umass.edu, n.d., para. 1 ).
