Comparative analysis of two solvents for determination of acid value in feed
The acid value of 20 kinds of feed raw materials and compound feed.such as soybean crude oil,rapeseed crude oil,soybean phosphatide oil,third-grade cottonseed oil,rapeseed meal,pig compound feed,chicken compound feed,and aquatic feed,were determined by automatic potentiometric titrator with two mixed solvents,ether-ethanol mixture and ether-isopropyl alcohol mixture.The results show that there is no significant difference in the acid value of the two mixed solvents,and both can be used.
