摘  要:
以玉米醇溶蛋白为原料,经适当的微粒化及乳化处理制备油脂模拟品。采用正交试验法对影响乳化及微粒化的因素进行了研究,确定出最佳条件:物料pH值6.5、温度35℃、剪切时间4 min、剪切速度1.3万r/min(17 m/s)、复合乳化剂配比(单甘酯∶羧甲基纤维素钠∶黄原胶)0.1∶0.1∶0.4。在此条件下乳化能力为66%,乳化稳定性为100%,平均粒度2μm,微粒化及乳化效果最好,产品拟脂效果最佳,具有天然奶油滑润细腻的口感和理想的物理性状。

摘  要:
Using zein as material,simulated fat of curn protein was manufactured through micronizing and emulsification.Main factors influencing its micronizing and emulsification were studied by orthogonal test.The optimum technology was determined: pH is 6.5,temperature is 35℃,shear time is 4min,shear rate is 13 000 r/min(17 m/s),the proportion of compound emulsifier(glycerin monostearate∶CMC∶gun xanthan) is 0.1∶0.1∶0.4.Under these conditions,emulsifying capacity is 66%,emulsifying stability is 100%,and the size is 2 μm.The product is of the best micronizing and emulsification effect,an exquisite taste and a smooth texture,and ideal physical characteristics of natural butter.
