Pseudocereals proteins- A comprehensive review on its isolation, composition and quality evaluation techniques

Abstract

In the recent years, there has been immense focus on the underutilized pseudocereals due to their high nutritional value, potential health benefits, bioactive properties and also as ideal candidate for gluten free products. The major focused pseudocereals are Amaranth, Buckwheat, Quinoa, Chia, Wattle and Album. The immense potential of these grains has led to the development of techniques for the isolation of important compositional components. Being rich in the proteins, different isolation techniques have been employed such as the physical, enzymatic and chemical methods. The high value of the pseudocereals extracted proteins in comparison to the conventional cereals was established by essential amino acid index, biological value and nutritional index. Based on the above, a clear perspective towards the isolation techniques was critically reviewed in this article. This review also documents amino acid composition, amino acid scores, in vitro digestibility values and protein efficiency ratio of the isolated proteins.
