Detailed Explanation of the Method for Determining the Acid Value of Full-Fat Rice Bran
Determination of the Acid Value of Full-Fat Rice Bran
I'd like to ask everyone:
The endpoint for determining the acid value of full-fat rice bran is hard to judge. What does everyone do? Is the acid value determined the same way as the acid value of oil?
--------------------------------------
Soak the rice bran in solvent naphtha or ether:ethanol (2:1) solution for about 40 minutes, recover the rice bran oil by distillation, then determine it according to the method for measuring the acid value of oil.
--------------------------------------
Sampling must be representative, and the ethanol must be anhydrous.
