Abstract

A technique to isolate DNA from ghee was developed for the authentication of beef fat product. The method was based on pre-mixed ghee with phosphate buffer solution (PBS) prior to DNA extraction using Epicentre extraction method. The recovery of beef DNA was then analysed by polymerase chain reaction (PCR) using beef species-specific oligonucleotide primers which targeted the mitochondria DNA (mtDNA) of cytochrome b (cyt b) gene. The amplicon was 274 bp in size. The developed ghee extraction method offers a high yield of DNA providing 100 ng per μl and useful for validating beef fat product.
