Determination of Pork Fatty Acid in Bulk Cooking Oil

Abstract

The increase in cooking oil prices in early 2022 will force people to switch from packaged cooking oil to bulk cooking oil, which does not have a brand or label. People cannot differentiate between bulk cooking oil produced by factories and recycled used cooking oil. Currently, people not only use vegetable cooking oil in their daily lives, but many people mix it with animal cooking oil to produce a more savoury taste in their dishes. This research aims to determine the fat content of pork based on the fatty acid composition and fatty acid levels in bulk cooking oil circulating in the community. The method used to determine the fat content of pork in bulk cooking oil samples is using GC-FID. The level of the fatty acid 11,14-Eicosadienoic Acid (C20:2) in pork fat, which is a marker for the presence of pork fat in the sample, is 0.57%, whereas it was not detected in the bulk oil sample.
