Xylitol is a naturally occurring sugar alcohol widely used in the food and beverage industry, as well as in oral care products. It is derived from various plant sources such as birch wood, corn cobs and bagasse, and can also be produced through microbial fermentation processes.

It is well - known for its sweet taste that is very similar to sucrose, but with a lower caloric value. This feature makes it a popular sugar substitute for people aiming to reduce calorie intake and manage body weight.

In addition to its role as a low - calorie sweetener, xylitol has excellent oral health benefits. It cannot be metabolized by the harmful bacteria in the mouth that cause tooth decay. Instead, it inhibits the growth and reproduction of these bacteria, and reduces the production of acidic substances that erode tooth enamel. As a result, it is commonly added to toothpastes, mouthwashes and chewing gums to help prevent cavities and promote dental health.

Xylitol also has a low glycemic index, which means it does not cause a rapid spike in blood glucose levels. This makes it suitable for consumption by individuals with diabetes or those following a low - sugar diet.

Moreover, it has good moisture - retaining properties and can be used as a humectant in baked goods and confectionery to maintain product freshness and texture.
