通过采用快速黏度分析仪(RVA)及损伤淀粉检测试剂盒的方法对新磨制以及储存30 d的两种小麦的7种粉样进行测定分析,研究在小麦粉熟化过程中淀粉的糊化特性及损伤淀粉含量的变化,以及面条制作品质变化,并探索小麦粉熟化过程中淀粉的糊化特性及损伤淀粉含量的变化与面条的质构和食用品质的关系.结果表明:新磨制的小麦粉峰值黏度、最终黏度、最低黏度均比储存30 d的小麦粉高,而损伤淀粉含量则低于30 d的小麦粉,采用RVA所测得小麦粉的淀粉特性与面条的黏附性呈显著性负相关,与面条的弹性、黏结性及回复性呈显著性正相关. 相似文献

测定了马铃薯小麦粉复合面条成型过程中马铃薯淀粉—小麦蛋白共混体系的热特性、黏度特性、微观特性以及复合面条的晶体结构、红外光谱、质构特性等,研究表明:在马铃薯淀粉—小麦蛋白共混体系的相互作用中,小麦蛋白对淀粉糊化起抑制作用,使淀粉原本的相变峰向高温移动,同时小麦蛋白对该体系的黏度起到削弱作用并对淀粉结构进行一定的稀释;马铃薯小麦复合面条与普通小麦面条相比结晶度较低,无定型的淀粉构象较多,持水力较强,复合面条的硬度、黏度、咀嚼性小于小麦面条,弹性、回复性、吸水率、断条率大于小麦面条。 相似文献

ABSTRACT Potato and sweet potato starches and derivatives thereof were used to substitute part of the wheat flour in white salted noodle (WSN) manufacture. The quality of the WSN obtained was compared with the quality of WSN made from wheat flour only. When up to 20% of wheat flour was replaced by acetylated potato starch and acetylated sweet potato starches, the cooking loss of WSN decreased, while the softness, stretchability, and slipperiness increased significantly. Native and hydroxypropylated starches did not exhibit these effects. It can be concluded that the substitution of part of wheat flour with acetylated starches strongly affects noodle-making and final noodle quality, and starch substitution can be used to change the performance of a given wheat flour for noodle making in a desired way. 相似文献

燕麦面团流变学及加工特性研究 总被引:9,自引:3,他引:9
以燕麦粉为原料,以中强筋小麦粉为对照,研究燕麦粉与小麦粉不同配比混合粉的面团流变学特性和食品加工特性.结果认为,与小麦粉相比,燕麦蛋白质组分中清蛋白、醇溶蛋白含量较低,球蛋白含量高,谷蛋白含量稍低.燕麦粉峰值、最大、最终黏度均小于对照小麦粉.加入燕麦粉后,面团形成时间延长,稳定时间降低.用淀粉代替燕麦粉,同样添加量下面包及馒头比容、总评分降低,面条吸水率、总评分降低,失落率升高.当面粉取代量大于5%时,对混粉食品制作品质有显著影响.加入10%、25%、10%燕麦粉制作面条、馒头和面包是较为理想的配比. 相似文献

为改善市售小麦粉(蛋白质11%)制作汤饭面片的面团特性和品质,在小麦粉中添加不同磷酸盐、食用胶类和淀粉,测定复配粉的糊化特性、面团特性以及面片复水后的品质比较。结果表明,磷酸盐能增加面粉峰值粘度、最低粘度、最终粘度、衰减值和回生值,对峰值时间、糊化温度影响不显著(p>0.05)。焦磷酸钠和三聚磷酸盐显著增加了面粉峰值粘度(p<0.05);聚丙烯酸钠显著降低了面粉回生值和衰减值(p<0.05),分别为767 cP、593 cP;马铃薯变性淀粉、木薯变性淀粉显著降低了面粉的回生值(p<0.05)。磷酸盐、食用胶对面团粉质特性有显著提高,淀粉降低了面团的粉质特性。六偏磷酸钠、三聚磷酸盐和焦磷酸钠弱化度最低,都为4 BU;聚丙烯酸钠、黄原胶弱化度最小分别为1 BU、4 BU。3种改良剂均能改善面片的剪切特性,除碳酸氢钠其他试验组能有效改善面片复水性和感官。三聚磷酸盐、黄原胶和马铃薯变性淀粉在试验组中对面片的硬度和延展性更好,复水性、品质和适口性更佳。综合评价:添加三聚磷酸盐、黄原胶和马铃薯变性淀粉能够较好的改善面团的特性和面片的品质,并能制作出适合加工新疆汤饭的方便面片。 相似文献

Although the processing and eating qualities of noodles are largely related to the quality and quantity of wheat protein (gluten), the importance of starch, a major ingredient of wheat flour, is often overlooked. Recent developments on the multilevel structural model of starch have brought new insights into the role of starch for better processing and noodle eating qualities. With critical analysis and discussion, this review outlines the comprehensive relationships between the multilevel (molecular, crystalline, and granular) starch structure, noodle eating qualities, and related physicochemical properties. Further, the major and minor structural features of wheat starch and their contributions toward noodle quality are summarized and presented as a schematic diagram, which shows the effects of starch structure on cooked noodles. These features provide new insights for the scientific community, as well as industry, into the role of starch, along with gluten, on the quality of noodles. 相似文献

以同一厂家不同产品不同批次的方便面生产专用面粉和相应的成品为研究对象,测定面粉的总淀粉含量、直链淀粉含量、降落值以及面粉的糊化特性、方便面的TPA 实验指标和感官品质等指标,并对其相关性进行分析,探讨面粉各指标对方便面感官品质的影响。结果表明:降落值和直链淀粉与起始糊化温度呈极显著正相关,与峰值黏度和方便面的各个感官指标呈极显著负相关;总淀粉含量与各个感官指标成极显著正相关。因此面粉中直链淀粉含量和降落值较低、总淀粉含量较高的时候,方便面成品感官品质较好。 相似文献
