Abstract
Dietary fibre intake is crucial for improving human health and reducing the prevalence of diet-related non-communicable diseases. This study determines the effect of the enzyme (Viscozyme®L: a cocktail of cell wall degrading enzymes including arabanase, cellulase, β-glucanase, hemicellulase and xylanase) hydrolyzed fibre on the techno-functional properties of puffed-extruded sorghum snacks made from sorghum flour. Sorghum flour and sorghum flour mixed with untreated bran, water-incubated bran, and enzyme-treated bran were extruded using a twin-screw extruder. The puffed-extruded snacks from sorghum flour with 2-h enzyme-treated bran showed similar expansion ratios to snacks from sorghum flour without bran. The expansion ratios of the without-bran snacks (2.80) and enzyme-treated bran-added snacks (2.77) were significantly (P < 0.05) higher than those made with untreated sorghum bran (1.87). A higher expansion ratio usually results in a lighter, crispier texture and a more attractive appearance of puffed-extruded snacks, which consumers often prefer. The enzyme treatment also increased the water solubility index and decreased the water absorption index compared to snacks with untreated bran. This study explores the potential of using an enzyme-treated sorghum bran to manufacture puffed-extruded snacks comparable to those made with sorghum flour.
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.
