Newly published test method takes Fruit d’Or cranberry and nutraceutical industry to a higher level
Industry leader Fruit d’Or proclaims, “Both manufacturers and consumers will benefit with new cranberry research!”
Cranberry industry leader Fruit d’Or is praising news that there is now a validated, published test method for quantifying insoluble proanthocyanins (PACs) found in whole fruit cranberry powder. The newly recognized test will open doors and change the landscape of cranberry research, enabling manufacturers to conduct reproducible studies and explore new structure/function claims. Fruit d’Or anticipates that the use of both whole fruit cranberry and cranberry seed powder to support gut health and overall wellness will be two strong areas of immediate research interest.
The study, published in the Journal of Agricultural and Food Chemistry , was conducted by Complete Phytochemical Solutions, LLC and Reed Research Group, Department of Animal Sciences, University of Wisconsin. The research team confirmed that insoluble cranberry PACs can be quantified using the butanol-hydrochloric acid method (BuOH-HCl) and a standardized (c-PAC) reference standard. Fruit d’Or provided the commercial cranberry products for the study.
Insoluble cranberry PACs: The final piece to the puzzle
Insoluble PACs tend to cling tightly to fibers and proteins, making them difficult to extract and quantify. Although they may represent more of the cranberry by weight than soluble PACs, their importance to our health has not been well scrutinized.
“Historically, most cranberry-related health outcomes were associated with juice and juice-derived products which contained only soluble PACs,” notes Kreuger. “Insoluble PACs have been an under-represented/unappreciated component of cranberry fruit. Now that the industry has moved into whole fruit products, insoluble PACs come into the equation. With the butanol test method, we can do a better job of providing formulators, marketers and health researchers with more complete compositional information of their starting material.”
“We are thankful for the work done by Christian Krueger, CEO of Complete Phytochemical Solutions, and the rest of the research team. Their study will propel the entire cranberry industry to new levels,” says Stephen Lukawski, director of Sales and Business Development for Fruit d’Or. “This newly accepted butanol test method will enable us to get a deeper understanding of cranberry’s health benefits, which will ultimately lead to higher sales of cranberry products.”
