Panel consisted of five men and five women (age group: 20–50 years with an average age of approximately 30 years). 3). In combination with amylases, this characteristic was enhanced, as observed upon the introduction of Aspergillus niger var. Birchwood xylan was procured from Sigma (Bayern, Germany). Journal of Food Processing and Preservation. Cans Of Bernard Dehydrated Water: What in the World is This? Longer shelf life bread can be achieved by preventing or reducing staling reactions and microbial growth (Fernandez et al. Xylanase imp-roved properties of white wheat bread and the higher effect is experienced with flour that has more active naturally existing amylases. Xylanases are added to dough to help break down polysaccharides in the wheat flours, and thus help stabilize the dough, make it more flexible, and improve gluten strength. Specifically, xylanase hydrolyzes a principal component of hemicellulose called xylan and arabinoxylan. Color measurements were carried out in triplicate and average values were used for calculation. Moreover, xylanases contribute to the decrease of dryness and stiffness of the dough with increasing elasticity, extensibility, and coherency, as well as increases in volume and decreases in bread density. 2012). Influence of Buckwheat and Buckwheat Sprouts Flours on the Nutritional and Textural Parameters of Wheat Buns. In this study, we looked into the protective effects of xylanase on yeast cells and its beneficial effects on frozen dough steamed bread.

Free sugars such as pentose and hexoses are released because of the hydrolytic action of hemicellulases/pentosanases (e.g., xylanases), which are then used by the yeast. Means of the same row followed by different letters are significantly different (, fraction of uncrystallized material at time t expressed in terms of firmness (dimensionless). Consequently, specific volume of xylanase‐supplemented bread (4.2 ± 0.11 mL/g) was significantly higher (P < 0.05) than that of control (3.5 ± 0.53 mL/g). As we are on a mission to enable better food for everyone we support bread improvers and bakers in creating natural, healthy and tasty bread that consumers love. The area represents the change of enthalpy (ΔH). 2006). These enzymes are involved in breaking down the hemicellulose in the cell walls of plants. Moreover, xylanase decreased dryness and stiffness of the dough whereas, resulted in increased elasticity, extensibility and coherency and increase in volume & decrease in bread density. Similar results have been reported by other workers (Haros et al. Partially purified xylanase was used in whole‐wheat bread manufacturing to study its effect on the quality attributes of the bread during storage at room temperature (25 ± 2C) and refrigerated temperature (4 ± 1C). Xylanase‐supplemented bread exhibited smoother mouth feel, better aroma and taste with non sticky mouth feel than control. Increase of loaf volume can be correlated with decrease in firmness value. Fat, total ash, acid insoluble ash, crude fiber, dry gluten and protein content were determined by the Association of Official Analytical Chemists (AOAC) methods (AOAC 1975). Food Science and Technology International. Means of the same row followed by different letters are significantly different (. Effects of different carbohydrases on the physicochemical properties of rice flour, and the quality characteristics of fermented rice cake. b* = 2.21). Bread made with xylanase supplementation was softer compared with control during storage (Tables 3 and 4). These undesirable effects can be minimized with the addition of gluten, surfactants, surfactant/shortening blends and hemicellulase enzymes (Sosulski and Wu 1988; Laurikainen et al. Additionally, to evaluate the impact of selected factors and their interactions two‐way and three‐way ANOVA was performed using Statistica 8.0 Software (Statsoft Inc., Tulsa, OK).
