  • Scientists have developed an efficient large-scale method to produce tagatose, a healthier alternative to regular sugar and artificial sweeteners.
  • Tagatose is a low-calorie natural sugar that does not cause sharp spikes in insulin levels.
  • Tagatose is about 92% as sweet as sucrose but contains only one-third of the calories.
  • It has a minimal impact on blood glucose, making it suitable for people with diabetes or insulin sensitivity.
  • A newly discovered enzyme from slime Mold—galactose-1-phosphate-selective phosphatase—was used in the process.
  • The new method achieved up to 95% production yield, far higher than existing techniques.
  • Tagatose occurs naturally in small amounts in fruits and dairy products.
  • It is tooth-friendly, may reduce harmful oral bacteria, and can withstand baking temperatures.
