Barley (Hordeum vulgare L.) is an important cereal crop and ranks fourth among the total cereals production but very little of this grain is used as human food. However, these days it is gaining popularity as functional grain because it contains higher amounts of bioactive compounds including beta-glucan (4-11%) and phytochemicals. The health benefits of barley beta-glucan and other bioactive compounds have been well documented. beta-Glucan is the most unique polysaccharide of barley which is associated with numerous health benefits including reduction of cholesterol, manage post postprandial blood glucose levels and acts as an anti-cancerous agent. Since food grains including barley are consumed after processing and it may alter the solubility, molecular weight and extractability of beta-glucan affecting the health benefits. Therefore, it is important to know the processing effects on beta-glucan to confirm such health claims for barley. Most of the review papers published are focused on the health benefits of beta-glucan. To the best of our knowledge, no comprehensive report is available on the effects of barley processing on beta-glucan content, molecular weight and beta-glucan extractability. The present article reviews the literature on processing effects on barley beta-glucan. (C) 2020 Elsevier B.V. All rights reserved.
