Introduction:
Stevia sugar features high sweetness and low calorie and its sweetness is 200-350 times of that of cane sugar but its calorie is only 1/300 of that of cane sugar.A large number of pharmaceutical tests have proved that stevia sugar has no side effects, carcinogens, and is safe for eating.
