植物乳杆菌改性玉米粉制作玉米面条的工艺及品质分析 总被引:2,自引:0,他引:2
以植物乳杆菌发酵改性玉米粉为原料,在谷朊粉添加量、沙蒿胶添加量、黄原胶添加量3个单因素试验的基础上,进行正交试验。通过对玉米面条穿刺功的测定与感官评价,确定发酵玉米粉制作玉米面条的最佳工艺配方。经过单因素和正交试验的分析,发酵改性玉米面条的最佳配方为:谷朊粉添加量6%,沙蒿胶添加量1.2%,黄原胶添加量0.6%。此工艺条件下所制得的发酵改性玉米面条最佳蒸煮时间为7 min,吸水率为159%,吸光度为0.119,有较低的浑浊度。而未改性玉米粉在此条件下无法和成面团。 相似文献

ABSTRACT
Effects of gelatinized corn flour addition level (40, 60 and 80%), gum (locust bean gum or xanthan gum, 3%) and/or transglutaminase (TG, 0.5%) on quality characteristics of corn noodle were investigated. Gelatinized corn flour was used as a binder for remaining untreated corn flour (60, 40 and 20%). Corn noodles were evaluated in terms of cooking properties (cooking loss, total organic matter (TOM), water absorption, swelling volume and maximum force), color, sensory and pasting properties. Noodle sample containing gelatinized corn flour at level of 80% exhibited best cooking and sensory properties. Gum and/or TG were added to this noodle formula. Gum improved noodle quality in terms of some cooking properties. Improving effect of xanthan gum was more obvious. Covalent crosslinks catalyzed by TG caused significantly lower cooking loss and TOM values. Gums generally caused increases in Rapid ViscoAnalyzer viscosity values of noodles. Gum and/or TG show great promise in processing of gluten‐free corn noodle.PRACTICAL APPLICATIONS
Celiac disease occurs in about one in 300 people in Europe. Lack of gluten in cereals that are safe for gluten‐free food causes major problems in dough processing and product quality. Technological difficulties in production and lack of awareness of number of celiac patients in need of gluten‐free products might restrict researches related to gluten‐free food. In recent years, various approaches to overcome the technological problems are arising. Searching for ingredients that have ability to mimic properties of gluten in production of gluten‐free food is the most common approach. We report herein beneficial effects of gelatinization, gum (locust bean gum, xanthan gum) and/or transglutaminase (TG) in gluten‐free corn noodle production. They have major improving effects in noodle quality and show great promise as a processing aid in bulk manufacture of gluten‐free corn noodle. To the best of our knowledge, there is no study investigating utilization of TG in gluten‐free corn noodles. 相似文献14.

研究3种常用淀粉对马铃薯米粉品质的影响,为马铃薯米粉加工提供参考依据。分别将0%、5%、10%、15%、20%和25%的玉米、小麦和马铃薯淀粉添加到马铃薯全粉占比30%的米粉中,测定米粉蒸煮、色差、质构和拉伸性能指标的变化。结果:添加不同淀粉使得米粉的含水量显著减小(p<0.05);玉米、小麦以及5%~20%马铃薯淀粉可使米粉透射比显著增大(p<0.05);10%玉米淀粉能使碘蓝值显著增大(p<0.05);添加10%玉米、5%小麦以及5%~20%马铃薯淀粉,能使吐浆值显著减小(p<0.05);但3种淀粉对断条率影响均不显著。添加10%玉米、10%小麦和5%马铃薯淀粉能使米粉亮度L*显著减小(p<0.05),色度值a*和b*亦发生不同改变。5%~15%玉米淀粉可有效改善米粉硬度、峰值负载,但添加量达到20%时峰值负载形变量显著减小(p<0.05);小麦淀粉可改善弹性,添加10%~15%可有效改善硬度,15%和20%可改善峰值负载和咀嚼性;马铃薯淀粉可提高米粉硬度,但添加量达20%时米粉变得黏连。在实际生产中建议玉米和小麦淀粉添加量分别为5%和10%。 相似文献
