Because the stevia glycosides resistant to acid and alkali, and within the scope of the pH4-10, heated to 100 ℃, its chemical structure will not change, will not produce microbial needed glucose, belongs to the material that is not of fermentation, often used in food preservation and drug mouldproof. Stevia glycosides in the human body little is metabolic, after the food won't produce too much heat, reason often used to make sweet food of obese patients, children eat sweet chrysanthemum beverage or stevia candies, etc., can avoid obesity to weight gain, prevent childhood obesity.
