A study was published on the peer-reviewed scientific journal Food Chemistry that took a look at samples of yeast beta glucans. It revealed that beta glucans each have a unique chemical structure, which depends on a couple of factors. The difference is attributed to the source or type of yeast strain and how they are isolated, processed and purified.
Further, due to the difference in structures, not all types can positively affect the immune system.
Beta glucans are soluble dietary fibers that promote immunomodulatory effects. Among those that were included in the study is Wellmune®, which is included in Kerry’s portfolio of ProActive Health products. This natural food, beverage and supplement ingredients helps strengthen the immune system and promote healthy ageing. It is gluten-free, Kosher- and Halal-certified, and comes in a Non-GMO Project Verified variant too.
Donald Cox, R&D Director at Kerry and one of the authors of the study, said: “We’ve long known that all beta glucans are not created equal when it comes to scientifically proven health benefits. What these new findings demonstrate is that each proprietary source of yeast beta glucan is structurally different.”
He added: “Because Wellmune has a unique chemical structure, the wealth of research carried out on it cannot be used to claim immune health benefits for other beta glucans. The next step is to investigate more about the way these structural differences affect functional benefits, and we hope to be at the forefront of this research.”
