目的 測定不同類型淀粉類黏合劑的黏度曲線,確定其使用的最佳濃度范圍。方法 探索不同類型淀粉的配制方法,采用數(shù)字旋轉(zhuǎn)黏度計測定不同種類淀粉黏合劑在不同溫度下的黏度并繪制黏度曲線圖。結(jié)果 不同種類的淀粉制成淀粉漿的黏度差異較大;所考察的5種淀粉漿的黏度拐點(diǎn)溫度范圍為40~50℃;預(yù)膠化淀粉和部分預(yù)膠化淀粉適合采用煮槳法配制淀粉漿,其他3種淀粉適合采用沖漿法配制淀粉漿。結(jié)論 作為淀粉漿使用的最佳濃度范圍分別是:玉米淀粉5%~8%,可溶性淀粉6%~8%,預(yù)膠化淀粉5%~8%,部分預(yù)膠化淀粉5%~8%,SWELSTARTMWB-1 1%~5%。

[Abstract]
Objective To determine the optimum concentration range for starch paste, the viscosity curve of different kinds of starch paste was measured. Methods The preparation method of different types of starch paste was examined and the viscosity of starch paste was measured at different temperature using digital viscometer. Besides, the viscosity curve was drawn according to the results. Results The results showed that there is a significant difference of viscosity between different kinds of starch paste. The turning point temperature of the five kinds of starch paste examined ranges from 40℃ to 50℃. Pregelatinized starch paste and partially pregelatinized starch paste were prepared using boiling method, but the other three kinds of starch paste were prepared by mixing the starch with hot water. Conclusion:The optimum concentration range for starch paste is:corn starch 5%~8%; soluble starch 6%-8%; pregelatinized starch 5%-8%; partially pregelatinized starch 5%-8%; SWELSTARTMWB-1 1%-5%.
