Rapid Screening of Adulteration in Pomegranate Juice with Apple Juice Using DSA/ TOF with Minimal Sample Preparation

چکیده
Pomegranate juice is in high demand due to its well documented health benefits. Studies based on a significant body of scientific research conducted on authentic pomegranate juice have established that pomegranate juice has superior antioxidant activity compared to other popular fruit juices such as grape, orange and apple1,2,3. These superior health benefits have led to a meteoric rise in the popularity of pomegranate juice over the last 10 years. This has resulted in pomegranate juice having a significantly higher cost than other juices, especially in comparison to apple, orange and grape juice. This high cost has provided an economic incentive for the adulteration of pomegranate juice4. There are a number of of other reasons for adulteration including: customers demanding their suppliers reduce costs; there comes a point when a supplier may adulterate the product to lower the cost and maintain a workable margin. Another reason for pomegranate juice adulteration is that it is in high demand and short supply, leading to incentives to extend limited supplies by the addition of other cheaper fruit juices.
