Toast your health with probiotic beer
SINGAPORE: It is a breakthrough worth raising a glass to.
Researchers in Singapore have brewed up a beer containing probiotic bacteria that can improve gut health and boost the immune system.
Food researcher Alcine Chan (23) experimented for almost a year with a recipe of malt, alcohol, hops and a strain of probiotic bacteria.
‘‘The hops are the main ingredient that kills probiotics, so we had to find a way for the probiotics to overcome the hops,’’ Chan said, demonstrating the prefermentation process in a laboratory at the National University of Singapore.
The popularity of beer promises huge market potential for the process, she said, adding that she hoped it would reach as many consumers as possible.
Chan, who perfected the beer recipe as a project for the senior year of her degree, said she drew inspiration from the probiotic yoghurt and dairy drinks she consumes every day.
The pale, bubbly drink tastes slightly sweet and has 3.5% alcohol content, just under the 4%6% of regular beers. Every 100ml of the drink, or roughly just over a mouthful, contains 1 billion probiotic organisms.
While probiotics have been shown to improve digestive function and boost the immune system, among other health benefits, project researchers stop short of making nutrition claims.
‘‘The beer is simply a new vehicle for delivering probiotics and the associated health benefits,’’ said Chan’s project supervisor, Liu Shao Quan.
