在生产计划安排时,尽可能先生产大规格瓦楞纸,使各种瓦楞纸板都受热均匀,糊化一致。
结果表明,微波处理降低了淀粉的膨胀度和溶解度、冻溶稳定性以及焓值,提高了糊化转变温度及转变温度范围。
面粉的峰值黏度、最后黏度与回升值都逐渐降低,而糊化温度变化不显著;
并且沉性水产饲料的糊化度由原先的70.5%提高到91.6%,达到浮性水产饲料的水平。
热特性分析发现随着脉冲电场强度的增大,起糊温度、峰值温度和糊化焓下降;
糊化温度与糊化温程升高,糊化时间延长,最高糊化黏度降低;
乙酰化改性降低了起糊温度,改善了淀粉的透明度和冻融稳定性,但粘度稳定性较差;
以可溶性淀粉为原料,通过对其氧化、糊化和接枝共聚等过程得到了改性淀粉;
用差示扫描量热仪和动态流变仪对不同水分含量的大米淀粉糊化、短期回生和长期回生特性进行了研究。
实地氮肥管理还明显降低了直链淀粉含量,提高了胶稠度,降低了糊化温度和蛋白质含量。
可知酸、碱可以促进黑血糯的糊化,而蔗糖则有一定的抑制作用。
使淀粉分子水合和溶解,总的来说,称之为淀粉的糊化过程。
表5不同处理因素水平对大米淀粉糊化度的影响单位:分钟,毫米。
太干燥时,黏合剂的膨润和粘合所必需的水分被原纸吸收,结果造成胶未糊化现象。
结果表明:随着发酵糙米粉添加量的增大,小麦粉的糊化黏度呈现下降的趋势;
1·Apparent amylose content (AAC), gel consistency (GC), and gelatinization temperature (GT) are recognized as the most important determinants of rice eating and cooking qualities.
