| Abstract: | The method of determination acid value was studied using titration directly in fish oil through drawing up the standard of fish oil from September 1993 to May 1994. The optimum condition and steps were been determined. The question that the titration destination changed slowly and the turbid solution appeared in the period of detecting was solved through using thymolsulfonphthalein that instead of phenolphthalein to indicator and 0.5 mol/L Potassium hydroxide solution to titrant and the mixture that was been mixed by ether and anhydrous ethanol mixed to the solvent. Therefore, the values detected is accurate and reliable. |
