Quality Assessment and Evaluation of Amino Acid Profile of Black Wheat Supplemented Noodles

Abstract

Background: Functional foods are a topic of ongoing industrial use and research. Currently, coloured grain is being prioritized more in research since it is a source of neutraceutical chemicals. Black colored wheat is known for its anthocyanin content. Black wheat therefore has the potential to offer extra health advantages over those that standard wheat cultivars typically offer. Noodles are most popular products widely consumed throughout the world and represents second in global consumption to bread. The present study was undertaken to evaluate effect of processing on loss of amino acids content in black wheat supplemented noodles and control white noodles. Methods: In the present study, High performance liquid chromatography was used for the quantification of amino acids in Black and Netravati white colored wheat flour and prepared black wheat supplemented noodles and control white noodles samples prepared by extrusion. Result: Black wheat flour and Black wheat supplemented noodles samples had higher total amino acid content, Essential amino acid content and per cent essential amino acid score in comparison Netravati white flour and control noodles samples prepared from whole Netravati white wheat flour, while content of lysine was more in Netravati white wheat flour and control noodles samples. The noodles samples prepared exhibited average percent reduction in amino acid content in black and Netravati white wheat were 1.06 and 2.63%, respectively. Black wheat flour and black wheat supplemented noodles were rich in anthocyanins also rich in amino acids in comparison to Netravati white wheat flour. Minimum losses in amino acid content were observed in Black wheat supplemented noodles, while maximum losses were observed in Netravati white wheat control noodles samples.
