Certified Reference Data Will Help Determine Berry Content Purity In Dietary Supplements

November 11, 2010: 03:55 PM EST

New certified reference materials developed by the National Institute of Standards and Technology (NIST) will help food manufacturers and researchers measure the levels of organic acids in dietary supplements containing vaccinium berries, i.e. cranberries, blueberries and bilberries. Dietary supplement makers often make health claims about products formulated with vaccinium berries, promising prevention of urinary tract infections, reduced risk of cancer or Alzheimer’s disease, and improved night vision. But sometimes products are diluted with less expensive juices to save money. By using the new standard reference materials (SRMs) scientists will be able to determine whether organic acid ratios specific to each berry have been tampered with. The new SRMs cover, among others, cranberry (fruit), low-calorie cranberry juice cocktail, cranberry extract, blueberry (fruit) and bilberry extract.
