中文摘要:采用球磨研磨法制备颗粒状冷水可溶玉米淀粉,在单因素试验基础上,采用Box-Benhnken中心组合试验及响应面分析法,优化制备工艺,并通过PLM、SEM和XRD等仪器分析其性质。结果表明最佳制备工艺条件为:球磨时间3.24 h,球磨机转速555 r/min,球料比6.52∶1,此时冷水溶解度的平均值可达到57.95%;淀粉颗粒表面变得粗糙,偏光十字消失,从多晶态转变成了非晶态,且淀粉糊浊度降低。

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. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
