造纸用变性淀粉的新发展 总被引:2,自引:0,他引:2
造纸用变性淀粉, 包括氧化淀粉、磷酸酯淀粉、阳离子淀粉等已在我国造纸工业得到了不同程度的应用。上述普通型( 一元) 变性淀粉自问世以来在反应效率、匀度和工艺条件等方面均有改进和提高,但因其自身带电荷等缺陷影响到它的使用效果和使用范围。变性淀粉正朝着两性或多元变性方向发展,并在我国近期已取得了初步的成效和进展。 相似文献

摘要:本研究比较了木薯淀粉、木薯醋酸酯交联淀粉和木薯磷酸酯交联淀粉对鱼糜加工性质的影响,并测定了二种木薯醋酸酯交联淀粉、二种木薯磷酸酯交联淀粉以及木薯淀粉和鱼糜加工相关的冻融稳定性、透光率、溶解性、膨润度和凝沉性等特性。并将木薯淀粉和四种变性淀粉分别添加到鱼糜中,测定鱼糜冻融过程中的持水性、白度以及凝胶强度等品质特性。结果表明:木薯变性淀粉因引入了磷酸基、羧甲基等亲水性基团,在透光率、冻融稳定性、溶解性和凝沉性等性质方面较木薯淀粉均有提高,添加木薯变性淀粉所得到的鱼糜制品白度、持水性和凝胶强度分别增加了17.7%、10.2%、77.7%。木薯变性淀粉较木薯淀粉更适合用于加工鱼糜。 相似文献

In vitro digestibility of hydroxypropylated and cross-linked waxy and non-waxy rice starches was investigated to find the proper resistant starch (RS) assaying method for chemically modified starches. RS and total dietary fiber (TDF) content of hydroxypropylated and cross-linked waxy and non-waxy rice starches were measured using the approved AOAC RS assay procedure (AOAC method 2002.02) and the AOAC TDF assay procedure (AOAC method 985.29). Hydroxypropylation did not alter the RS content of waxy and non-waxy rice starches (less than 1% of RS). Cross-linking also did not change the RS content of waxy and non-waxy rice starches (less than 1% of RS). It is interesting to note that non-RS content decreased with increasing hydroxypropylation (97-80%) and cross-linking (99-95%) in both waxy and non-waxy rice starches. This indicates that some fraction of RS in hydroxypropylated and cross-linked waxy and non-waxy rice starches cannot be measured using approved AOAC RS and TDF assay procedures. Therefore, the RS and TDF assay procedures performed in this study are not appropriate to determine the RS content of chemically modified starch. Further investigation is needed to develop a method to determine the RS content of chemically modified starch. 相似文献

ABSTRACT: Textural stabilization of extruded beef jerky analogs (BJA) by using modified starches was studied. From a series of modified starches studied, Frigex W and Instant Pure Flo were identified to show very reduced retrogra-dation, both in gels and after extrusion. These starches were used as textural stabilizers for BJA, an extruded product obtained from potato granules and ground beef. The partial substitution of potato granules with modified starches, at a level of 5% of the formulation, led to increased moisture sorption capacity of the analogs. After a storage period of 1 mo, the samples that contained modified starch had a degree of swelling with 30% higher and much lower elastic modulus as compared to those that contained only potato starch. 相似文献
