Recently, the ABC-AHP-NCNPR project BAPP released a new LGD about Vaccinium macrocarpon.
In view of the low-cost PACs obtained from other plant sources, such as peanut skin or grape seed, cranberry PACs are largely replaced and cannot be distinguished by experimental analysis, which brings a lot of uncontrollable risks to consumers while obtaining high profits.
Anthocyanins range in color from red to blue, and anthocyanin-rich extracts are used to mimic the color of the cranberry extract. This is a relatively common method of adulteration and has been officially announced. The document also details the chemical composition of the cranberry, the species that may be confused, and the known adulterants. TLD was peer reviewed by 20 international experts from academia, government, third-party contract analysis laboratories and the herbal medicine industry.
The constant changes in the process and the differences in the origin of the cranberry will have an impact on the ingredients, and finding an analytical method that can detect all types of adulteration becomes challenging. Depending on the product specifications, a complete set of test methods may be required. But this is another resource that is urgently needed by industry and third-party laboratories to ensure that the testing methods they use are effective to regulate the global market.
