The purposes of this study were to determine the effect of citric acid concentration on the content of water content, free fatty acids, and to determine the fatty acid content in the refining of crude coconut oil into coconut cooking oil. Water content and free fatty acids are important factors in determining the quality of cooking oil. The experimental method was employed by using variations in citric acid concentrations of 0.2%; 0.5%; and 1% in the degumming process and using KOH as a caustic base in the neutralization process. The water content was measured using the gravimetric method, free fatty acids were analysed by acid-base titration, and fatty acid components were analysed by GC-MS. The application of citric acid with low concentration showed that free fatty acid and water content decreased at 0.2% concentration by 0.25% and 0.04%, respectively. The water content met the requirements of ISO 8904-2020, which is 0.3%, but the free fatty acid content did not meet the requirements of ISO 8904-2020, which is 0.1%. Fatty acids contained in coconut cooking oil refined from crude coconut oil consisted of caprylic acid 12.7%, capric acid 9.42%, lauric acid 45.59% and palmitic acid 1.82%. The main fatty acid content in coconut cooking oil is lauric acid. The level of similarity between the coconut cooking oil produced in the study and packaged coconut cooking oil based on aroma was 13.3% and colour was 46.7% based on organoleptic tests.
