Protein is an important component of the human body which is made up of amino acid. Protein ingredients are derived from various sources such as animals, plants, insects, and microorganisms. These ingredients are primarily known for their properties such as viscosity, foaming, emulsification, water binding property, and nutritional properties. Moreover, growing demand arising from population growth, and increased demand for protein globally is driven by socio-economic changes such as growing incomes, rising urbanization, and aging populations whereby the contribution of protein to healthy aging is progressively recognized and acceptance of the role of protein in a healthy diet.
