Abstract
Oils are mainly complex mixtures of triacylglycerol with other compounds such as monoband diacylglycerol, free fatty acids, phosphatides, sterols, fatty alcohols, fat-soluble vitamins, chlorophylls, and other substances. Adulteration of oils severely affects the quality of the oil, Palm kernel oil is the most widely used adulteration in the industry, and it severely affects human health. In this experiment different concentration of palm kernel oil was added to adulter the coconut oil and other brands of commercially available coconut oils were used in the experiment. In this study, the Raman spectroscopic method and excitation-emission matrix method were employed to understand the changes in adulterated oil at different concentrations and in commercially available oils in the market.
