    摘要:

    采用球磨研磨法制備顆粒狀冷水可溶玉米淀粉,，在單因素試驗基礎上，采用Box-Benhnken中心組合試驗及響應面分析法,，優(yōu)化制備工藝,，并通過PLM、SEM和XRD等儀器分析其性質,。結果表明最佳制備工藝條件為：球磨時間3.24 h,，球磨機轉速555 r/min，球料比6.52∶1,，此時冷水溶解度的平均值可達到57.95%,；淀粉顆粒表面變得粗糙，偏光十字消失,，從多晶態(tài)轉變成了非晶態(tài),，且淀粉糊濁度降低。

    Abstract:

    The method of planetary ball mill was applied to produce granular-cold-water-soluble maize starch. Based on the single-factor test, the technical conditions of the ball mill were optimized through Box-Benhnken center composite design and response surface methodology. The properties of granular-cold-water-soluble maize starch were analyzed using polarization microscopy, scanning electronic microscopy and X-ray diffraction. The results showed that the optimum technical conditions are that the milling time is 3.24h, the rotating speed is 555r/min and the ratio of ball to material is 6.52∶1. At the optimum conditions, the average cold water solubility of granular-cold-water-soluble maize starch is 57.95%. The granular morphology of granular-cold-water-soluble maize starches became coarse instead of smooth and Maltese crosses were disappeared, the crystalline structure of granular-cold-water-soluble maize starches were changed from polycrystalline granules to non-crystalline granules gradually, the turbidity of granular-cold-water-soluble maize starch decreased. 
