Sugar alcohols, also known as polyols or hydrogenated carbohydrates, are a class of carbohydrate compounds commonly used in food and pharmaceutical applications due to their unique properties. They are derived from naturally occurring sugars through chemical hydrogenation processes. These compounds provide a sweet taste without the high caloric content typically associated with sucrose, making them ideal for low-calorie products. Sugar alcohols have a lower glycaemic index compared to sugar, meaning they cause a slower and milder increase in blood glucose levels, which is beneficial for individuals managing diabetes or seeking healthier alternatives. Commonly used sugar alcohols include sorbitol, xylitol, mannitol, and erythritol. They are widely utilized as humectants, providing moisture retention properties that enhance the texture of food products. In pharmaceuticals, sugar alcohols serve as excipients, contributing to formulations for oral tablets, chewable tablets, and suppositories due to their stability and taste-modifying abilities. Additionally, they can act as preservatives, enhancing the shelf life of various products by preventing moisture loss or microbial growth.
