Fruit d’Or helped to pioneer a way to differentiate soluble and insoluble PACs within the cranberry fruit using a MALDI TOF method developed in concert with a natural products chemist at the University of Wisconsin. With that fingerprinting technique in place, the company says it can now guarantee a minimum 7% PAC content in both of its brands, Cran d’Or and Cran Naturelle organic.
The company says it can also now guarantee that level of bioactives over a three-year shelf life.
“Fruit d’Or whole fruit cranberry powder maintains its natural bright red color over three years with little PAC degradation. No other whole fruit cranberry supplier can say this,” said Stephen Lukawski, lead sales consultant and product development partner for Fruit D’Or Nutraceuticals.
Lukawski said having that solid characterization of the material in hand has been a key to building up the scientific suite behind the ingredients. The company says it has linked its specific PAC levels to bacterial anti adhesion benefits (the mode of action that helps to suppress the development of urinary tract infections) via studies conducted at Rutgers University.
