The objective of this work was to evaluated the effects of debranning (2% and 4%) of Indian and exotic wheat varieties on pasting, protein profile and rheological properties of meal. Exotic varieties grains showed significant difference in cooking properties despite having similar protein content. Debranned grains of exotic varieties showed significantly lower water uptake (WU) than those from Indian varieties. Ash content, protein content and mixographic properties (mixing time, dough strength) of meal decreased with increase in extent of debranning. With increase in debranning level unextractable polymeric proteins (UnEx-PP) decreased while unextractable monomeric proteins (UnEx-MP) increased. Exotic varieties had lower extractable PP as compared to Indian wheat varieties. With increase in debranning level pasting parameters (final, breakdown and peak viscosity) increased. Exotic varieties showed the higher gluten strength indicated by mixographic parameters. Wheat grains debranned to 4% debranning level showed better cooking properties. Exotic wheat varieties showed better pasting and mixing properties as compared to Indian wheat varieties.
本研究旨在评估印度和外来小麦品种去麸皮(2%和 4%)对粉的糊化、蛋白质图谱和流变学性质的影响。尽管蛋白质含量相似,但外来品种的谷物在烹饪特性上存在显著差异。去麸皮的外来品种谷物的吸水率(WU)明显低于印度品种。随着去麸皮程度的增加,灰分含量、蛋白质含量和粉质参数(混合时间、面团强度)降低。随着去麸皮水平的提高,不可提取的聚合蛋白(UnEx-PP)减少,而不可提取的单体蛋白(UnEx-MP)增加。与印度小麦品种相比,外来品种的可提取 PP 较低。随着去麸皮水平的提高,糊化参数(最终、崩解和峰值黏度)增加。通过粉质参数显示,外来品种具有更高的面筋强度。去麸皮水平达到 4%的小麦籽粒具有更好的烹饪特性。与印度小麦品种相比,外来小麦品种具有更好的糊化和混合特性。
