The newly recognised test will enable manufacturers to formulate new cranberry products beyond UTIs and create a higher bar for quality standards
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 recognised test will enable manufacturers to conduct reproducible studies and explore new structure/function claims.
The Canadian company 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 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 standardised (c-PAC) reference standard. Fruit d’Or provided the commercial cranberry products for the study.
Insoluble PACs tend to cling tightly to fibres 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 scrutinised.
“Historically, most cranberry-related health outcomes were associated with juice and juice-derived products which contained only soluble PACs,” noted Christian Krueger, CEO of Complete Phytochemical Solutions. “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.”

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.”
There are many benefits to having a recognised test method for quantifying insoluble cranberry PACs.
Lukawski says this test method is the final piece of the puzzle. “This is great news for the cranberry industry, especially researchers and formulators. It enables manufacturers to formulate new cranberry products beyond UTIs, generate greater sales and create a higher bar for quality standards.
“Fruit d’Or is in the whole fruit business. We are a zero-waste, sustainable company and believe in what mother nature has given us to work with. We want to understand all the components within the fruit, but we couldn’t do that without an accepted, validated test method for insoluble PACs,” Lukawski added. This is a foundational tool that will enable us to continue our work with researchers and scientists on the efficacy behind the cranberry. Our goal is to take cranberry beyond UTI and make it a lifestyle ingredient. Cranberry every day for everyone.”
