Researchers create probiotic beer that boosts immunity and improves gut health

Beer lovers may soon have a gut-friendly drink to raise a toast to, thanks to the creation of a novel probiotic sour beer by a team of researchers from the National University of Singapore (NUS). This new specialty beer incorporates the probiotic strain Lactobacillus paracasei L26, which was first isolated from human intestines and has the ability to neutralise toxins and viruses, as well as regulate the immune system.

Studies have shown that consuming food and beverages with live counts of probiotics are more effective in delivering health effects than eating those with inactive probiotics. By propagating the probiotic and yeast in pure cultures, and modifying conventional brewing and fermentation processes, Miss Chan managed to increase and maintain the live counts of the strain of probiotic. “For this beer, we used a lactic acid bacterium as a probiotic micro-organism. It will utilise sugars present in the wort to produce sour-tasting lactic acid, resulting in a beer with sharp and tart flavours. The final product, which takes around a month to brew, has an alcohol content of about 3.5 per cent,” explained Miss Chan. The NUS research team has filed a patent to protect the recipe for brewing the probiotic sour beer.

Assoc Prof Liu said, “The general health benefits associated with consuming food and beverages with probiotic strains have driven demand dramatically. In recent years, consumption of craft or specialty beers has gained popularity too. Alcine’s invention is placed in a unique position that caters to these two trends. I am confident that the probiotic gut-friendly beer will be well-received by beer drinkers, as they can now enjoy their beers and be healthy.”

Looking ahead, Assoc Prof Liu and Miss Chan are keen to collaborate with industry partners to introduce the beer to consumers.
