ABSTRACT: We investigated the rheological properties of the Japanese wheat product tenobe somen noodles manufactured using a unique traditional process—\" Te-nobe (hand-stretched).\" In an extension test, the maximum resistance to extension (Rmax ) and extensibility until rupture (Erup) of boiled somen noodles were measured on a Texture Analyzer in the tension test mode and compared with those of machine-made somen noodles. The Rmax and Erup values per unit cross-sectional area were significantly higher for boiled tenobe somen noodles than for machine-made somen noodles, clearly indicating the higher resistance to extension and extensibility of the former. A compression test performed using the Texture Analyzer in the biting-test mode revealed that although the maximum force of compression (Fmax ) was lower for boiled tenobe somen noodles than for machine-made somen noodles, the former had more characteristic texture than the latter, which was shown by comparing the force-deformation curve of each somen noodle. Scanning electron microscopy revealed differences between dried tenobe and machine-made somen noodles, which may reflect their rheological differences. Lateral and sectional micrographs of tenobe somen noodles showed regular arrays of starch granules and gluten networks, and some air spaces. Tenobe somen noodles exhibited significantly higher dityrosine content than the flour used for their manufacture, indicating that tyrosine residues in gluten proteins cross-link during the manufacturing process; however, the dityrosine content in tenobe somen noodles were not higher than that in machine-made somen noodles. 相似文献

在三种不同筋力梯度的中筋面粉中分别添加不同比例的食盐并制作面条,测试了食盐对面粉的糊化特性和熟面条品质的影响,探讨了食盐含量与面粉糊化特性及面条品质间的相关性。结果表明:添加食盐对面粉的糊化特性和面条的质构和蒸煮特性均产生了一定的影响。食盐比例与面粉的初始糊化温度、面条的硬度、粘附性、胶黏性和蒸煮吸水率均呈极显著正相关,与面粉崩解值和面条的干物质失落率呈显著负相关,与面条的最佳蒸煮时间呈极显著负相关,与其他指标间的相关性不显著。综合上述结果得出食盐的添加量为面粉质量的0.75%时,面条整体品质水平最好。 相似文献

为促进马铃薯主食化战略,本文通过添加不同含量的马铃薯淀粉,对面团特性及发酵面条的蒸煮特性、质构特性及消化特性等指标进行测定,探究马铃薯淀粉添加量对其的影响。结果显示:随着马铃薯淀粉添加量的增加(0%~55%),混合粉的糊化起始温度降低,热焓值增加,终止温度无明显变化;混合粉面团的吸水率、形成时间和稳定时间均呈下降趋势,使得发酵面条的硬度、弹性和咀嚼性均显著下降(P<0.05)。模拟淀粉体外消化发现淀粉水解速率随马铃薯淀粉添加量的增加而升高,与对照组相比,添加马铃薯淀粉后血糖生成指数预测值显著降低(P<0.05)。结论:马铃薯淀粉添加量为45%时,混合粉面团及发酵面条的糊化、质构特性和消化特性较好。 相似文献

Viscograph paste viscosity parameters of starches isolated from 42 wheat varieties were highly correlated with each other and with measures of the quality of the derived Japanese white salted noodles. Better correlations with noodle quality were obtained when measurements of wheat protein and grain hardness (PSI) as well as a starch viscosity parameter were included in the regression equations. 相似文献

通过单因素实验研究不同改良剂对马铃薯面条质构特性、拉伸特性与蒸煮特性的影响,利用变异系数法分析得到不同改良剂作用下各个指标所占重要性大小,并经过各指标的标准化值与权重的相关计算,得到4种改良剂对马铃薯面条品质影响的大小。结果表明:不同指标对马铃薯面条品质影响大小依次为:断条率(0.048) > 拉伸力(0.205) > 弹性(0.086) > 干物质损失率(0.065) > 黏聚性(0.048) > 拉伸距离(0.036) > 干物质吸水率(0.031) > 回复性(0.027) > 硬度(0.020)。不同改良剂对面条品质影响大小依次为:黄原胶(1.5467) > 谷朊粉(1.4304) > TG酶(1.3878) > 食盐(0.9818)。通过电镜观察,30%马铃薯粉面条添加改良剂食盐1.5%、黄原胶0.6%、TG酶0.6 U/g、谷朊粉8%,在此条件下制得的马铃薯面条微观结构得明显改善。变异系数法不仅可用于马铃薯面条品质改良研究,也可成为食品领域产品开发研究中指标选择的较好方法。 相似文献

为探究蓝靛果多酚提取物(Lonicera caerulea berry polyphenol extract,LCBP)对面条品质及消化特性的影响,明确多酚在面制品加工中的应用价值。本试验研究了LCBP对小麦淀粉(Wheat starch,WS)的老化性及体外消化性的影响。以未加多酚的面条为对照,研究了多酚对面条品质特征的影响,使用扫描电镜观察了添加多酚前后的面条的形貌结构。结果表明,LCBP显著降低了WS的老化性(P <0.05)。与未加LCBP的淀粉组相比,多酚添加量为16%时,淀粉基样品中快消化淀粉(Rapidly digestible starch,RDS)降低了46.32%,慢消化淀粉(Slow digestible starch,SDS)和抗性淀粉(Resistant starch,RS)含量分别升高了0.95倍和0.61倍。添加12%多酚的面条感官评分较高(91.83分),表面较光滑、紧实,断条率为5.00%,干物质损失率为9.34%。与对照组相比,添加12%多酚的面条RDS降低了29.52%,SDS和RS含量分别升高了0.22倍和1.32倍,GI值显著下降至54.58(P <0.05)。综上,LCBP有助于抗消化,对降低面条的GI值有促进作用,且多酚添加量不超过12%的情况下可在保持面条风味的同时提高营养价值,这为低GI值功能性食品的开发提供了建议。 相似文献

Wheat germ is an available and economical source of protein, vitamins and antioxidants with an increasing application in food products. The main aim of this study was to investigate the effects of different levels (0.0, 2.5, 5.0, 7.5 and 10.0%) and particle sizes (120, 210 and 354 μm) of wheat germ on physicochemical properties of fresh chilled dairy dessert. With increasing wheat germ level, dry matter of the dessert increased while the pH decreased. Particle size had no significant effect on these parameters. Increasing the wheat germ content and particle size enhanced darkness, hardness, cohesiveness and gumminess of the desserts while decreasing springiness and water release of the samples. Wheat germ level had greater effects on different quality aspects of the desserts than its particle size. The most acceptable dessert was produced with no more than 5.0% wheat germ with either of the particle sizes used in this study. 相似文献

Starch noodles are gaining interest due to the massive popularity of gluten-free foods. Modified starch is generally used for noodle production due to the functional limitations of native starches. Raw materials, methods, key processing steps, additives, cooking, and textural properties determine the quality of starch noodles. The introduction of traditional, novel, and natural chemical additives used in starch noodles and their potential effects also impacts noodle quality. This review summarizes the current knowledge of the native and modified starch as raw materials and key processing steps for the production of starch noodles. Further, this article aimed to comprehensively collate some of the vital information published on the thermal, pasting, cooking, and textural properties of starch noodles. Technological, nutritional, and sensory challenges during the development of starch noodles are well discussed. Due to the increasing demands of consumers for safe food items with a long shelf life, the development of starch noodles and other convenience food products has increased. Also, the incorporation of modified starches overcomes the shortcomings of native starches, such as lack of viscosity and thickening power, retrogradation characteristics, or hydrophobicity. Starch can improve the stability of the dough structure but reduces the strength and resistance to deformation of the dough. Some technological, sensory, and nutritional challenges also impact the production process. 相似文献
