中文摘要:对扁豆淀粉颗粒特性和糊化特性进行了研究。结果表明,扁豆淀粉颗粒多为蚕豆形,表面光滑,大小不一,粒径为8~22μm,平均为15μm。大颗粒淀粉的轮纹和偏光十字十分明显,十字多为“X”形。与玉米淀粉、红薯淀粉和绿豆淀粉相比,扁豆淀粉糊透明度高,具有较差的冻融稳定性,易凝沉。扁豆淀粉的起糊温度较低,糊的热稳定性好,但易老化。添加食盐、碱面和明矾,提高了扁豆淀粉的起糊温度、降低热稳定性、减弱老化程度。食盐对糊化特性的影响较小,碱面和明矾的影响较大。

Abstract: The physical and chemical properties of haricot starch granules and paste were studied in this paper. Most granules of haricot starch are like horse bean, and the surface is smooth. The granules of haricot starch have different diameters, which varies from 8 to 22μm with the average value 15μm. It has apparent ring lines and polarization crosses, and most of the polarization crosses are of X-shape. Compared with cornstarch, sweet potato starch and mung bean starch, haricot starch has high transparence and poor freeze-thawing stability, but its retro-gradation is easy. The temperature of gelatinization is lower; the hot paste has high stability. Adding to salt, sodium carbonate or alum, the temperature of gelatinization increases, the hot paste stability declines, and its retro-gradation slackens. Except salt, sodium carbonate and alum have significant influences on the paste properties.

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.
