在小麦中添加不同比例的发芽小麦,研究对小麦、小麦粉品质特性及食用品质的影响。选择发芽小麦按照不同比例(1%、5%、10%、15%、20%、25%、30%)与正常小麦进行混合,研究发芽小麦不同添加比例对小麦及小麦粉品质特性产生的影响,并对不同添加比例发芽小麦粉制作的馒头和面条食用品质进行评价。结果表明:随着发芽小麦比例含量的增加,混合小麦及小麦粉品质特性指标中除降落数值逐渐减少,其他特性指标与正常小麦相比较无明显变化。对馒头和面条进行蒸煮实验评价,可以看出当发芽小麦含量不超过15%时,对其食用品质无明显影响,但当发芽小麦含量超过20%时,馒头出现粘牙,当发芽小麦含量超过15%时,面条韧性下降,食用品质受到影响,评分值均在80分以下。 相似文献

小麦籽粒品质与馒头品质关系的研究 总被引:7,自引:1,他引:7
馒头是我国主要食品之一,消费量和面条相当,且南方的消费量还在逐年增长。21世纪以前,国内学者对制做馒头小麦粉品质的要求,馒头品质的评价方法,馒头品质与小麦品种籽粒品质的关系所能提供的研究资料十分有限。国外学者从70年代起就一直注意跟踪和研究这些问题。由于馒头的地域种类较多,不同人群对馒头的喜好不同,评价馒头品质指标的标准化程度不够,使不同结果之间有一定的差异,或完全相反。作者通过对小麦品种籽粒品质的分析,制作馒头面团发酵特性和油炸结果测定,馒头品质的评价认为:馒头对小麦粉品质的要求范围较大,从中筋到弱筋小麦品种都可以制作馒头;筋力愈高,面团的发酵时间愈长,馒头的弹性愈高;小麦品种小偃107制作的馒头色白,体积较大;小偃107的发酵面团在油炸过程中体积增加,有可能表现出吸油率低的特点。 相似文献

The influence of inulin with different degrees of polymerisation (DP) on the farinograph characteristics, extensograph parameters and fermentation rheological properties of soft and strong wheat dough was explored. The results showed that the addition of inulin can reduce the water absorption of doughs, and inulin with lower DP had more significant effect and the influence on the soft dough was stronger than the strong dough. Inulin can enhance mechanical properties of the gluten network and improve the resistance to mixing of soft dough. The extensibility of doughs decreased with increasing inulin. Inulin increased the resistance to extension of soft dough; however, it is reverse for strong dough. Adding inulin significantly increased the volume of gas production and the maximum expansion height of doughs, and the effect of inulin with lower DP was more prominent. Additionally, the gas‐holding capacity of doughs was enhanced by inulin. 相似文献

This study aimed to evaluate the effects of incorporation of aleurone-rich fraction (ALF) on the hydration and rheological properties of wheat dough. Incorporation of ALF significantly increased water absorption (P < 0.05) and competition for water in dough was observed. Peak viscosity, through viscosity, and final viscosity decreased with the amount of ALF added (P < 0.05), whereas 20% ALF had stronger gel ability than whole-wheat flour. Dynamic rheological experiments revealed ALF blend dough were more stable than whole-wheat dough, which was in accord with the higher dough stability and strength observed in Mixolab. Scanning electron microscopy showed that disruption of gluten network with ALF incorporation, whereas 20% ALF showed better stability dough structure than the whole-wheat dough. Considering those influences on dough properties, the 20% ALF seems to be a promising substitute for whole-wheat flour to producing dietary fibre-rich products. 相似文献

本文采用质构分析法、感官评价法、流变学法、糊化特性测定等方法,探讨了不同添加量的8种木聚糖单酶(xyl-A1、xyl-A2、xyl-A3、xyl-A4、xyl-A6、xyl-A7、xyl-HI、xyl-HII)对裸麦粉面包品质、裸麦粉面团流变特性、裸麦粉糊化特性的影响。结果表明:裸麦粉面包中8种木聚糖单酶xyl-A1、xyl-A2、xyl-A3、xyl-A4、xyl-A6、xyl-A7、xyl-HI、xyl-HII的适宜添加量分别为0.5mg/kg、5mg/kg、0.1mg/kg、0.5mg/kg、0.5mg/kg、2mg/kg、0.2mg/kg、0.1mg/kg。其中,添加木聚糖酶xyl-A2对裸麦粉面包的品质改善最好,其次是木聚糖酶xyl-A7。添加木聚糖酶xyl-A2能显著改善裸麦粉的稠度特性和拉伸特性;木聚糖酶xyl-A3可以改善裸麦粉面团的稠度特性,但对拉伸特性无明显影响;添加木聚糖酶xyl-A7、xyl-HI、xyl-HII也可改善裸麦粉面团的稠度特性,但对裸麦粉面团的拉伸特性有一定的负面影响。添加木聚糖酶在一定程度上可改善裸麦粉的糊化特性,增强裸麦粉的热稳定性,改善裸麦粉面团的老化速度。 相似文献
