Barley flour addition decreases the oil uptake of wheat chips during frying

Abstract

In the present study, wheat chips enriched with barley flour at different concentrations (5, 10, 15, 20, 25 and 30%) were produced and some physicochemical and textural properties, fatty acid composition and sensory quality of enriched chips were investigated. An increase in the values of some physicochemical parameters of wheat chips, namely hardness, dry matter, ash and some fatty acids levels, was observed with the increasing barley flour concentration in the formulation. Barley flour addition provided a significant oil uptake reduction as the oil content of the control sample was 27.23% while that of the enriched samples with 30% barley flour was 18.21%. Overall acceptability of wheat chips added with no barley flour samples was determined to be similar to compared to enriched ones. But addition of barley flour higher than 10% caused a decrease in sensory scores of the final products.
