Nutritional and quality analysis of quinoa seed flour fortified wheat biscuits

Abstract

Improvisation towards a healthy lifestyle is a necessity of today. Quinoa is a pseudo cereal and it's seed is rich in essential amino acids such as methionine, threonine and lysine which are limiting in most other cereals. It also contains large amounts of minerals like calcium, iron, zinc and copper. Hence, it can be used in preparation of fortified products. The influence of fortification of wheat flour with quinoa seed flour in different ratios (90:10), (80:20), (70:30) and (60:40) were studied. The proximate analysis, sensory analysis and physical properties of samples were analysed. On the basis of nutritional value, biscuits with ratio (60:40) were acceptable as it contains high fibre content and high ash content as compared to other samples. On the basis of sensory evaluation, whole wheat flour biscuits and 10% fortified biscuits scored highest among all samples. Fortified quinoa seed flour biscuits were found to be highly nutritious.
