Breakthrough converts brewery waste into a safe, low-calorie sweetener with a glycemic index of just 7.
SOLAN, Himachal Pradesh, Nov 6 (The CONNECT) – Every morning, Dr. Srishti Mathur walks past Shoolini University’s lush campus, where the mountains cradle the valley and the air still smells of pine.
In one of the university’s quiet labs, she has spent the last few years working on something that could change the daily lives of millions of people living with diabetes.
Her breakthrough? A natural, low-calorie sweetener—xylitol—produced not through expensive industrial chemicals, but from something most people throw away: the leftover grain from beer brewing.
“Most people see waste,” she says with a smile. “We saw possibility.”
Brewer’s spent grain (BSG), which is usually discarded or ends up as animal feed, is now being transformed into a sugar alternative with a glycemic index of just 7, compared to regular sugar’s 68. For diabetics who scan food labels before every meal, this could mean more freedom, less fear, and the simple joy of sweetness without guilt.
The method developed by Dr. Mathur uses a gentle yeast fermentation process—no harsh chemicals, less energy, and nearly 40% lower production costs. Four patents now protect the innovation, which was guided by senior scientists Prof. Dinesh Kumar and Dr. Vinod Kumar.
This new xylitol isn’t just healthier—it is planet-friendly.
What was once waste is now value.
Xylitol is already approved by the FSSAI in India and recognized as safe by the U.S. FDA. It can be used in chocolates, beverages, baked goods, chewing gums, and everyday home cooking. It also reduces harmful oral bacteria and lowers the risk of cavities—something even dentists cheer for.
“At a time when diabetes is rising in almost every Indian household, and industries are struggling with waste disposal, this solution connects both challenges,” explains Dr. Mathur. “It’s good for people, and it’s good for the planet.”
The discovery also advances the UN Sustainable Development Goals promoting responsible consumption and sustainable industry. And with the global xylitol market already valued at $1.2 billion, the impact could be far-reaching.
At Shoolini University, recognized among India’s leading research institutions, such breakthroughs are nurtured quietly—but their ripple effects could travel far.
And perhaps someday soon, a child with diabetes, or an elderly parent carefully measuring sugar spoons, may find sweetness returning to their plate—without worry.
