浸出法制取大豆油黄色结晶体析出物的测定分析与防控措施

Analysis and control measures of yellow crystalline precipitates during soybean oil extraction by leaching method

浸出法制取大豆油生产过程中,在尾气回收系统的部分设备中出现了微量黄色结晶体析出物。采用库仑滴定法对这种黄色结晶体析出物检测发现其含硫量为8. 408%。通过对出现硫素的分析,提出了防控措施,为大豆油安全生产、大豆油的食品安全、大豆油的研发等提供了参考。

In the extraction of soybean oil by leaching method,trace yellow crystalline precipitates appeared in some equipments of the vent gas recovery system.The sulfur content in the yellow crystalline precipitates was 8.408%determined by Coulometric titration.Through the analysis of the sulfur,some control measures were put forward so as to provide reference for the safe production,food safety,research and development of soybean oil.
