Pengaruh Media Terbuka dan Tertutup terhadap Kadar Asam Lemak Bebas pada Kondisi Suhu Kamar The Influence of Open and Closed Media on Free Fatty Acid Levels at Room Temperature

Abstract

Free fatty acids (ALB) are fatty acids that exist in a free state and are no longer related to glycerol. The method used in ALB analysis in CPO uses the alkalimetric titration method with the principle of determining acid levels using a standard alkaline solution that has known the exact concentration. The data collection process is carried out by calculating the % ALB in open and closed media CPO which is then calculated in excel to find out the comparison of the increase in % ALB so that the graph is obtained. a significant increase occurs in open media CPO because open media is more rapidly oxidized and more susceptible to contamination by air so that there is a faster increase in open media samples so that in open media the smell is more rancid than closed media due to the result of oxidation, namely hydroperoxide which gives a rancid smell and gives a brownish color to CPO.
