Erythritol and xylitol can be from the sweetness, cooling effect, energy coefficient, safety and tolerance, hygroscopicity, body absorption metabolism amount of six aspects of the difference between the two.

1, sweetness is different

The relative sweetness of xylitol is almost the same as sucrose, 1.0, the relative sweetness of erythritol is about 0.7, the relative sweetness of xylitol is higher.

2, the cooling effect is different

Xylitol and erythritol have a sense of cool, but the cooling effect of erythritol is better than xylitol. This is due to the highest heat of dissolution absorption of erythritol, erythritol heat of dissolution of -43 kcal/g, xylitol -36.5 kcal/g.

3, energy coefficient is different

In GB 28050-2011 Q&A, the provisions of the energy coefficient of erythritol is 0 kJ/g, xylitol energy coefficient of 10 kJ/g. In fact, the energy coefficient of erythritol is about 1.7%, the energy coefficient of erythritol is about 1.7%. In fact, the energy coefficient of erythritol is about 1.7 kJ/g, and xylitol is 16.7 kJ/g.

4. Safety and tolerance are different

The tolerance of erythritol is about 2 times of that of xylitol, and that of erythritol is about 0.68?g/kg of body weight for men, and 0.8?g/kg of body weight for women; and that of xylitol is about 0.3?g/kg of body weight for men, and 0.3?g/kg of body weight for women. /kg body weight for men and about 0.3-0.5?g/kg body weight for women.

Xylitol overconsumption will produce side effects such as bloating, intestinal chirping and diarrhea, while erythritol tolerance is higher, less likely to cause gas production or mild diarrhea and other side effects.

5, hygroscopicity different

Xylitol hygroscopicity than erythritol high: erythritol in 90% air humidity will not be hygroscopic; xylitol in the relative humidity 86% (23 ℃, 2d) water absorption is about 7.64%.

6, body absorption and metabolism of different

Erythritol into the body, because it can not be digested by any enzyme system degradation, can only be filtered through the kidneys from the bloodstream, through the urine out of the body. Another 10% enters the large intestine, which also can hardly be utilized by bacterial fermentation.

80% of xylitol is metabolized by the liver, more than 50% is converted to glucose, about 45% is oxidized, and a very small portion of the rest becomes lactic acid.
