Abstract:
... Beta glucans are complex glucose polymers well known for their immune modulatory properties. Therefore they are used and advertised in dietary supplements. Unfortunately there is no standardized test system for quality control of such health-related foods. This approach combined wet chemical and enzyme-based quantification methods (e.g. aniline blue, Glucatell®) with a cytokine secretion assay as ...
