Authenticity is an important issue nowadays as humans are concerned about the quality of food they consume.Goat's milk contains more protein. carbohydrate, vitamins and minerals compare to other milk such as cows's milk. It contains less lactose and smaller fat globules than cow's milk. The composition of the goat's milk is known by people nowadays, especially the one who has lactose intolerant who cannot consume lactose and who are looking for a better milk nutrient. In this regard, determining the origin of milks using their deoxyribonucleic acid (DNA) composition is of high importance. For this research, we will determine the authentication of commercialized also known as factory goat's milk by comparing it with fresh also known as raw farm goat's milk using DNA extraction method with the PROMEGA Kit of Genomic DNA. Thus, it can show the presence of milk origin by DNA in each of the milk samples collected. This study shows clear presence of DNA of milk and serve as a parameter for quality control of milk.
