(1) Low calorie: Erythritol has low calorie value of 1.65 kJ/g, sucrose is 16.7 kJ/g, xylitol is 11.7 kJ/g, and erythritol is the lowest energy functional sugar. The heat is only one tenth of the sucrose heat. Because of its small molecular weight, it is easily absorbed by the human body, and only a small amount enters the human large intestine and is fermented by microorganisms. 80% of erythritol is eaten by human body and enters human blood, but it cannot be catabolized by enzymes in the body, and is not provided for the body. Energy, not participating in sugar metabolism, can only be discharged from the body through urine. The experiment proves that the maximum daily consumption of human erythritol is 20 grams, and the energy decomposed by the human body can be utilized, which is only 0.67 kJ/g.
(2) High tolerance: The body's tolerance to erythritol is 0.8 grams per kilogram of body weight, which is higher than xylitol, lactitol and maltitol. The main reason is that the molecular weight of erythritol is small and absorbed. Less, mainly through the discharge of urine, thus avoiding the occurrence of diarrhea caused by hyperosmotic phenomenon, avoiding the phenomenon of flatulence caused by intestinal bacterial fermentation.
(3) Anti-caries: erythritol is not used by human oral bacteria, so it does not cause acid damage to the teeth, which causes the teeth to metamorphose and inhibit the growth of oral bacteria, thus protecting the teeth. Role
