The practice of blending cheap palm oil with more expensive oils is currently rampant owing to the increased global price of oil and the price gap between types of oils. This adulteration poses a serious threat to the trade of edible oil and negatively affects consumers. The aim of this study was to identify the presence of palm oil as an additive in more expensive oils using a PCR-based technique. A taxon-specific gene, MT3-B, was found by searching the GenBank database. MT3-B showed high oil… CONTINUE READING
