Recent scientific advancements have led to a groundbreaking method for producing tagatose, a unique natural sugar that mimics the taste of regular sugar without causing significant spikes in insulin levels. This innovation could provide healthier alternatives to artificial sweeteners, appealing to health-conscious consumers.
Tagatose is a naturally occurring sugar found in modest amounts in various fruits and dairy products. It is approximately 92% as sweet as sucrose, yet it contains only one-third of the calories. The unique metabolic properties of tagatose result in a minimal impact on blood glucose levels, making it an excellent choice for individuals with diabetes or insulin resistance. Additionally, tagatose is tooth-friendly, potentially inhibiting the growth of harmful oral bacteria.
A collaborative effort between researchers at Tufts University and biotechnology companies Manus Bio and Kcat Enzymatic has resulted in a highly efficient method for large-scale tagatose production. Their findings were published in the scientific journal Cell Reports Physical Science.
To address the high costs and inefficiencies associated with traditional production methods, scientists engineered Escherichia coli bacteria to function as miniature production facilities. By introducing a newly identified enzyme from slime mould known as galactose-1-phosphate-selective phosphatase, the researchers successfully converted glucose into tagatose. This innovative process achieved production yields of up to 95%, significantly surpassing current commercial methodologies.
Tagatose's heat stability allows it to withstand baking temperatures, unlike many artificial sweeteners. Researchers believe that this new production method could significantly broaden the commercial applications of tagatose and similar rare sugars. The global market for tagatose is anticipated to reach $250 million by 2032, reflecting a strong demand for healthier sugar alternatives.
