Isomalt is a sugar substitute made from beet sugar. It is classified as a sugar alcohol and is commonly used in sugar-free candies and desserts. Isomalt has about half the calories of regular sugar and does not significantly affect blood sugar levels, making it a popular choice for people with diabetes. This ingredient is known for its ability to mimic the texture and sweetness of sugar while providing a lower glycemic index. Additionally, isomalt is resistant to fermentation, which means it does not contribute to tooth decay, making it a dental-friendly option in various food products.
