Just-released Symposium Summary also documents the importance of using the right analytic tools and reference standards

Fruit d’Or Nutraceuticals has come out in support of a recent Cranberry Institute Symposium Summary, which closely mirrors the company’s ongoing work to strengthen the three primary pillars it says are essential to the future growth and survival of the cranberry industry: authenticity, standardization and efficacy.

Why the Cranberry Institute developed its own standardized whole cranberry powder

The Cranberry Institute provides health research funding to academic and industry laboratories. However, the concerns of no standardization of biomarkers in natural cranberry products, the lack of continuity between products used and similar lack of understanding of the correlation between product composition and the ultimate health outcome, had become increasingly problematic.

To support research conducted and underwritten by the Cranberry Institute, the organization developed its own whole cranberry powder from the fruit itself. Then, working with Complete Phytochemical Solutions, a third-party consulting and testing botanical ingredient company, a specification sheet was created to send to researchers along with the materials. That specification sheet includes the material’s entire composition including fiber, protein, flavonols and proanthocyanidins (PACs) levels.

“The Cranberry Institute contracted with us to conduct the analysis,” confirmed Complete Phytochemical Solutions CEO Christian Krueger, who has introduced breakthrough test methods for measuring cranberry’s soluble and insoluble proanthocyanidins PACs and has also developed new reference standards such as C-PAC. “The material’s certificate of analysis provided to researchers incorporates the standard reference material, which is an improvement over the previous HPLC or DMAC A2 testing standard; results of a butanol-HCl assay for quantification of insoluble (non-extractable) proanthocyanidins; DMAC C-PAC assay for quantification of soluble proanthocyanidins and fingerprint analysis for identification and prevention of adulteration via MALDI-TOF testing. Each powder produced is also tested for efficacy.”

Fruit d’Or is praising the synergies between this approach and its own initiatives  

“This action by the Cranberry Institute acknowledges that there are many important constituents to cranberry fruit that aren’t often captured in either cranberry extracts or juice powders,” commented Stephen Lukawski, director of Sales and Business Development for Fruit d’Or, a pioneer in the cranberry industry for more than 15 years.

He emphasized that the Institute’s decision to verify its cranberry material is also meaningful because Fruit d’Or has been following this protocol with its own whole-food cranberry powders, Cran d’Or and Cran Naturelle, and is advocating for the entire cranberry industry to follow suit. “This Cranberry Institute study rubber stamps all of the work that Fruit d’Or has been doing. It also dovetails with the work of the Cranberry Quality Assurance Program (CQA), a five-star supplier quality testing program designed for cranberry suppliers to guarantee that the cranberry being manufactured and sold has been tested to ensure identity, safety, purity and efficacy.”

He added that Fruit d’Or is the first cranberry nutraceutical company from farm to factory to adopt its own reference standard for whole-food natural cranberry powders. “We were first to open these new doors, and it is gratifying that the standardization and use of state-of-the-art analytical tools, are now supported and validated by another industry leader.”

Krueger stated: “The Cranberry Institute Summary Report recognizes the need for identification, standardization and efficacy. This need is not exclusive to the cranberry industry. Now that the tools and expertise exist, if you’re doing a clinical study on any raw ingredient or formulated product, you should be mandated to know its composition. How else can you link the efficacy with the material used?”

Concluded Lukawski, “Formulators and researchers must first understand what is in the cranberry powder before any research and science can be conducted. What good are studies of they cannot be measured or replicated? The process should be to first identify your cranberry, know what’s in it (such as its PAC activity), link the PAC to standardization, then conduct the study to establish efficacy. Currently, no other cranberry supplier has done this and therefore lack standardization and efficacy of their cranberry ingredients.

“Fruit d’Or Nutraceuticals is committed to being the industry leader in terms of doing the right thing for both the consumer and the cranberry industry. With the complementary work by the Cranberry Institute, we welcome new research opportunities knowing that we have the right tools in place to provide DNA authentication, measure PACs, fight against adulteration, and establish the efficacy and standardization which are lacking in today’s cranberry industry.”
