Abstract
Summary Brewer's spent grain is the most prevalent low‐cost by‐product of brewing industry, contributing to about 85% of all by‐products produced. It is of interest for food industry applications because of its high nutritional value (fibres, protein and bioactive substances). The objective of this study was to determine the effects of different brewer's spent grain composition usage on various quality criteria of noodles as well as to investigate the possible usage opportunities and assessments of them in the production of noodles against obesity. For this purpose, noodle production was carried out using five different compositions of brewer's spent grain barley, barley and wheat, barley and rice, barley and maize, barley and finger millets, all at different concentrations (5%, 10%, 15% and 20%). Various quality criteria of the noodles were determined. Noodles made with the addition of barley and maize spent grains were found to be high in physio‐chemical and nutritional properties, and amylase and lipase inhibition assay. Concentration above 15% of spent grains affected the texture of the noodles. From the sensory evaluation, 10% concentration of barley and maize noodles was selected as it had good texture, colour and appearance. It was comparatively good in taste and aroma from other samples.
