Saccharine 

Saccharin is a non-nutritive or artificial sweetener. It is commonly used as a sugar substitute because it doesn’t contain calories or carbs. Humans can’t break down saccharin, so it leaves your body unchanged. It’s around 300–400 times sweeter than regular sugar, so you only need a small amount to get a sweet taste. Food manufacturers often use saccharin because it’s fairly stable and has a long shelf life. It’s safe to consume even after years of storage. In addition to carbonated diet drinks, saccharin is used to sweeten low-calorie candies, jams, jellies, and cookies. It’s also used in many medicines. Saccharin can be used similarly to table sugar to sprinkle onto food, such as cereal or fruit, or used as a sugar substitute in coffee or when baking.
