Improving PAC Testing of Cranberries

LAKEVILLE-MIDDLEBORO, Mass.Ocean Spray Cranberries, Inc. is collaborating with Complete Phytochemical Solutions to develop a cranberry-based, cranberry-specific PAC standard. The goal of the project is to improve the accuracy of measuring and quantifying proanthocyanidins (PACs) in cranberries. The new standard will serve as an alternative to the Procyanidin A2 (dimer) standard currently utilized in the DMAC1 method. Ocean Spray and Complete Phytochemical Solutions hope to make the cranberry PAC standard commercially available to the cranberry industry, academic institutes and contract research organizations.

Tom Jones, senior manager, business development, Ocean Spray ITG, said, We are committed to supporting scientific research on the health and wellness benefits of cranberries and have made this investment to support the industrys quest for a solution to the long standing debate on PAC measurement. An improved standardized method will add further scientific validation to our high quality, innovative ingredient portfolio as well as establish an industry-wide standardized testing methodology."

Accurate quantification of PAC content in cranberry products is a vital component in establishing dosage guidelines for consumers. Additionally, it is essential for monitoring efficacy and shelf-life of dietary supplements, as well as helping standardize test materials used in research studies.
