To overcome the variability in performance of yeast cell wall products, Ohly is introducing a new yeast cell wall product produced from primary cultivated yeast by hydrolysis: Ohly-GO Wall. This product combines the health benefits of mannan oligosaccharides (MOS) and beta-glucans.

With the increasingly widespread ban on the subtherapeutic use of antibiotics in farming, there is a growing demand for alternatives. Yeast cell walls are widely used for this purpose and their benefits are well accepted. Generally, they are a byproduct from the yeast extract industry or produced from brewer’s or biofuel spent yeast. Therefore, the MOS and beta-glucan content of such products varies largely. Moreover, yeast cell walls are spheres. Hence the components that are on the outside of the yeast cell wall interact with the host and determine its function.

Conventional yeast cell walls are mostly the result of yeast autolysis, and their outer layer contains MOS, hence the common referral to yeast cell walls as MOS. In contrast, the outer layer of yeast cell walls produced by hydrolysis contains a mixture of beta-glucans and MOS.

Ohly-GO Wall is a new product of robust composition that is produced by hydrolysis of primary cultivated yeast. It contains both MOS and beta-glucans on its outside, allowing it to fight microbial infections by two modes of action: pathogen binding as well as immune stimulation.

Mariët van der Werf, Ohly global platform director feed health, said, “Nutritionists at animal feed companies rightly demand proof of the benefits of feed ingredients based on the results of animal trials. However, product consistency and product structure are as important in order to realize these benefits in a robust manner.”

Ohly is a supplier of yeast-based specialty products for the global food, fermentation, feed and health markets. Ohly is part of the ABF Ingredients group (ABFI), which develops, produces and markets specialty ingredients for the food, beverage and nutrition, feed, pharmaceutical sectors, as well as for a variety of other industrial applications.
