The use of vital wheat gluten in the baking industry and wheat flour mills aims to improve the rheological characteristics of flour considered unsuitable to obtain products such as sliced bread, French bread, high‐fiber breads, and other products that require strong flours. To improve characteristics such as flour strength, dough mixing tolerance, and bread volume, vital wheat gluten is added to flour at levels that can vary from 2% to 10% (flour basis), with 5% being a commonly used dosage. However, the vital wheat gluten commercialized in the market has few quality specifications, especially related to the characteristics of the proteins that constitute it and are responsible for the formation of the viscoelastic gluten network. Information on protein quality is important, because variations are observed in the technological quality of vital wheat gluten obtained from different sources, which could be associated to damage caused to proteins during the obtainment process. Several tests, either physical–chemical analyses, or rheological tests, are carried out to establish gluten quality; however, they are sometimes time‐consuming and costly. Although these tests give good answers to specify gluten quality, flour mills, and the baking industries require fast and simple tests to evaluate the uses and/or dosage of vital gluten addition to wheat flour. This review covers the concepts, uses, obtainment processes, and quality analysis of vital wheat gluten, as well as simple tests to help identify details about protein quality of commercial vital wheat gluten. 相似文献

添加糯小麦粉对小麦粉及其面条品质特性的影响 总被引:1,自引:0,他引:1
糯小麦与普通小麦的主要差异是糯小麦不含直链淀粉或其含量很低,其对面制品的制作品质产生一定的影响。本研究利用"济糯1号"分别与"济麦20"和"济麦22"按20%、40%、60%和80%的添加量进行配粉,研究糯小麦粉对普通小麦粉品质特性的影响及其面条制品品质的改良作用。结果表明:"济糯1号"的淀粉糊化回升值为449 c P,显著低于"济麦20"和"济麦22";籽粒硬度达64.89,籽粒蛋白质含量(干基)达16.14%,面筋指数为66.08%,粉质仪稳定时间为2.00 min,鲜面条色泽变化小,2 h和24 h的ΔE*分别为3.83和5.29;"济糯1号"与"济麦20"的配粉中,随糯小麦粉添加量的增加,配粉的淀粉回升值降低,面筋指数降低,吸水率增加,面团稳定时间变短,鲜面条色泽2 h和24 h的ΔE*逐渐变小,配粉面条的适口性和光滑性更好;"济糯1号"与"济麦22"的配粉中,随糯小麦粉添加量的增加,面粉蛋白含量增加、面筋指数升高、吸水率增加、淀粉糊化的回升值降低,鲜面条色泽2 h和24 h的ΔE*逐渐变小,配粉的面条制作品质好,面条的适口性和光滑性均改善;糯小麦粉的添加使配粉的面粉品质特性和淀粉特性更有利于面条制作品质的改良,"济糯1号"适宜添加量为20%~40%。 相似文献

QUALITY OF SWEETPOTATO FLOUR DURING PROCESSING AND STORAGE 总被引:2,自引:0,他引:2
M. Van Hal 《Food Reviews International》2000,16(1):1-37
Sweetpotato flour can easily be promoted as a substitute for wheat flour in sweet baked products and can also be used for its high carotenoid content. However, the price of the sweetpotato flour must be competitive with wheat flour and be of good quality. This article defines and describes the different quality characteristics of sweetpotato flour. After an overview of the different steps and equipment used in the small-scale processing of sweetpotato flour, the influence of the different processing steps and storage on the quality characteristics are reviewed. 相似文献

Balady bread was prepared from barley flour (Rum and ACSAD 176 flour) with local wheat flour (Unified and Zero flour). Chemical, physical, and sensory analysis of the bread was performed. The results showed that there were variations in physical and chemical properties, between different barley varieties, barley flour, and the bread. This study showed that barley flour can be mixed with wheat flour to provide Balady bread that is acceptable to the consumer by 15 and 30%. Additional portions of barley flour resulted in harder bread, darker color, non uniform-shaped loaf, and unacceptable quality for the consumer. The results also showed a better quality of unified wheat flour compared to Zero wheat flour, which was mixed with barley flours; Rum and ACSAD 176 produced a better overall bread quality that was acceptable to the consumers. 相似文献
