Abstract

The study investigates the effect of microwave (MW) treatment on the quality characteristics of pearl millet flour. Three-level full factorial design was applied, with MW power level (100, 200 and 300 W) and treatment time (30, 60 and 90 s) as independent variables. The response variables were proximate composition, functional properties, flour properties, colour, relative lipase activity, antinutrients, degree of gelatinization and bioactive components. The relative lipase activity reduced considerably from 219.76 to 31.98 μg oleic acid. mL⁻¹. Antinutrients like phytates and tannins decreased by 16.30% and 87.32% after it was treated with higher MW power levels and exposure time. Functional properties, degree of gelatinization and flour properties were considerably impacted by MW treatment. Antioxidant activity and total flavonoid content decreased from 94.06 to 93.06% and 2.75 to 1.23 mg. g⁻¹, respectively. Multivariate analyses like hierarchical cluster and principal component analysis had been applied to find the correlation among the parameters.

期刊介绍： The Journal of Cereal Science was established in 1983 to provide an International forum for the publication of original research papers of high standing covering all aspects of cereal science related to the functional and nutritional quality of cereal grains (true cereals - members of the Poaceae family and starchy pseudocereals - members of the Amaranthaceae, Chenopodiaceae and Polygonaceae families) and their products, in relation to the cereals used. The journal also publishes concise and critical review articles appraising the status and future directions of specific areas of cereal science and short communications that present news of important advances in research. The journal aims at topicality and at providing comprehensive coverage of progress in the field.
