淀粉作为一种天然的可再生资源,广泛地应用于工业生产中,但是,原淀粉冷水溶解度差以及粘度低等性质严重的影响了其在工业生产中的应用。淀粉的传统应用方法是将其加热糊化,糊化淀粉的结构呈非颗粒态,口感差,影响了在食品工业生产中的应用效果。

As a natural renewable resource, starch is widely used in industrial production. However, the poor solubility and low viscosity of raw starch in cold water seriously affect its application in industrial production. The traditional application method of starch is heating gelatinization. The structure of gelatinized starch is non granular and the taste is poor, which affects the application effect in food industry.
颗粒状冷水可溶淀粉的研制,扩大了淀粉在工业中的应用范围。本文以玉米淀粉为原料,通过球磨法制备颗粒状冷水可溶淀粉,研究了不同球磨条件对玉米淀粉冷水溶解度的影响。在此基础上,对颗粒状冷水可溶玉米淀粉的粒度、结晶结构、颗粒形态、透明度、凝沉特性、冻融稳定性以及糊化曲线进行了分析研究,为颗粒状冷水可溶淀粉工业化生产提供理论依据。

The development of granular cold water soluble starch expands the application range of starch in industry. In this paper, corn starch was used as raw material to prepare granular cold water soluble starch by ball milling. On this basis, the particle size, crystal structure, particle shape, transparency, coagulation characteristics, freeze-thaw stability and gelatinization curve of granular cold water soluble corn starch were analyzed and studied, which provided theoretical basis for industrial production of granular cold water soluble corn starch.

Corn starch was used as raw material to prepare granular cold water soluble starch by ball milling. The effects of the type of ball milling tank, ball to material ratio, filling rate, rotation number of ball mill and milling time on the cold water solubility of corn starch were discussed.
实验结果表明,聚四氟乙烯球磨罐不适合冷水可溶淀粉的制备,陶瓷和不锈钢球磨罐在条件下制备的冷水可溶玉米淀粉的冷水溶解度分别为73.31%和73.41%
The results showed that PTFE ball mill was not suitable for the preparation of cold water soluble starch. The cold water solubility of cold water soluble corn starch prepared by ceramic and stainless steel ball mill was 73.31% and 73.41% respectively
