成膜条件对腐竹品质的影响研究

文章旨在研究腐竹揭皮过程中的品质变化规律以及浆液浓度、温度和添加剂对其的影响.通过控制影响成膜的这3个关键因素,测定不同揭皮次数下的腐竹拉伸断裂力、伸长率和质量,以此作为衡量腐竹筋力和弹性的指标.通过实验发现,浆液浓度每增加1％,腐竹的拉伸断裂力、伸长率和质量平均分别提高13.8％、6.3％和13.1％,浓度对腐竹影响...

Study on the Effect of Film-Forming Conditions on the Quality of Yuba

The purpose of this paper is to research the change rules of quality and the influence of soybean milk concentration,temperature and additives on the process of yuba formation.By controlling three critical factors,the tensile breaking force,tensile rate and mass of yuba under different making times were measured,which were used as the indexes to measure the strength and elasticity of yuba.The results showed that the tensile breaking force,tensile rate and mass of yuba increased by 13.8%,6.3%and 13.1%respectively with the soybean milk concentration increasing by 1%,total statistical results of yuba F>2.776 indicating homogeneity of variance and P<0.01 proved that the difference was very significant;the three indexes were increased by 36.1%,11.1%and 26.6%when the temperature was increased by 5℃.Total statistical results of temperature influence on yuba F>2.776 indicating the homogeneity of variance,P<0.01 of tensile breaking force and mass proved the difference was very significant;0.01
