USP Uses Biothera Info for Beta Glucan Monograph

EAGAN, Minn.The United States Pharmacopeia (USP) developed the first official monograph for beta glucan from bakers yeast (Saccharomyces Cerevisiae) using  a reference standard contributed by Biothera. Biothera also provided two methods for identifying and quantifying the beta 1,3/1,6 branched glucan polymer derived from the cell walls of bakers yeast as well as additional methods to ensure the purity of the material.

The Biothera identification method uses Nuclear Magnetic Resonance Spectroscopy to detect glucan branch linkages.  To quantify the purity of the beta glucan content, Biothera developed the Glucan Enzymatic Method (GEM) Assay that was published in the ACS Journal of Agricultural and Food Chemistry.

The monograph was issued in the Third Supplement of the Seventh Edition of the Food Chemicals Codex, an internationally recognized compendium of standards for the purity and identity of food ingredients. The USP Expert Committee approved the proposed monographs after being published in Pharmacopeial Forum for public comment.  USP sets standards for manufacturers to comply for products legally marketed in the United States. These monographs address quality, identification, labeling, purity, and potency, among other tests. All beta glucans from bakers yeast must fulfill the requirements of the USP monographs, at a minimum. The monographs will facilitate FDAs determination of compliance of the marketed products to these public standards.

Biothera is pleased to share its expertise in carbohydrate chemistry to help set the industry standard for characterizing and analyzing beta glucan from bakers yeast," said Rich Mueller, Biothera chief executive officer.

We are pleased the USP recognized the technical merit of our analytical methods, and validated and adopted our analytical methods as part of the new monograph," said Andy Magee, Ph.D., Biothera vice president of Chemistry. 

Beta glucan is a natural food, beverage and dietary supplement ingredient with immune health benefits.  Biothera manufactures Wellmune WGP®, a proprietary bakers yeast beta glucan clinically proven to prime key immune cells that help keep the body healthy and vital.
