Beta-Glucan
Beta-glucan is a type of soluble fiber found naturally in a variety of food sources such as oats, barley, and rye. It’s associated with numerous health benefits, including lowering cholesterol levels, and improving immune health. Beta-glucan is found in the cell walls of certain types of plants and some yeasts, bacteria, fungi, and algae. Due to its many benefits, beta-glucan is a popular ingredient in dietary supplements aimed at improving cholesterol levels, boosting immune function, managing diabetes, supporting digestive health, and aiding in weight loss or maintenance.
Beta-Glucan can be adulterated or contaminated during the manufacturing process, in a number of ways:
Dilution with Fillers
Fillers can include bulking agents such as cellulose, maltodextrin, or other fibers.
Mislabeling Source or Concentration
A product might claim to have beta-glucan from a specific source, like mushrooms or oats, but in reality, it might contain beta-glucan from a less expensive or less effective source. Similarly, the actual concentration of beta-glucan might be lower than what is claimed on the label.
Mixing with Synthetic or Non-Natural Beta-Glucan
There is also the potential for natural beta-glucan to be mixed with synthetic versions or beta-glucans that are not naturally sourced, which can affect the efficacy and safety of the product.
Modification of Molecular Structure
In some cases, the molecular structure of beta-glucan may be altered to cut costs or simplify the production process, which can affect its bioavailability and health benefits.
Why NMR for Beta-Glucan?
Detecting adulteration in yeast beta-glucan is possible with Nuclear Magnetic Resonance (NMR) Spectroscopy: As a non-targeted analytical technique, NMR can also identify what else is in the supplement’s formulation.
