Mannitol is a sugar alcohol (polyol). It has a good flavor with little after taste. It has 1.6 calories per gram, 40% the value of sugar but it has only 50% of the sweetness.
So it is not really useful as part of a calorie controlled diet, as it has 80% the calories of sugar for the same sweetness. It does, however, have a very low glycemic index (It is only 2, sugar is 65) and consequently it is very suitable for diabetics.

It is nonhygroscopic, meaning it does not absorb moisture from the atmosphere. This makes it very suitable as a hard coating for candy, and gives it certain desirable qualities in chocolate flavour coatings. Like other sugar alcohols it has a laxative effect, and in fact is used for this purpose in certain medicines, especially for children. It is not recommended to consume more than 20 gm per day.
Not used as a sweetener on it's own. But it has considerable uses in the pharmaceutical industry as a drug in it's own right, and as a coating for pills and tablets. It has very beneficial applications in medicine and is also used in the food industry.
It has a very low glycemic index and this makes it suitable as part of a diabetic diet. Like all sugar alcohols it is not metabolized by bacteria in the mouth and so it does not contribute to tooth decay. It also helps the appearance, shelf life and texture of food products in the absence of sugar. It has a long list of medical applications including:
1. Treatment for head trauma.
2. Treatment for renal failure.
3. Treatment of cystic fibrosis.
4. As a laxative for children.
5. As a coating and binder for pills and tablets.
It has a laxative effect. Also some people can be allergic to it. It occurs naturally in plants, but in small amounts. So
care should be taken to avoid high consumption. Additionally, because it has powerful medical effects on the body, large doses can be particularly serious, leading to renal failure and even heart failure. This does not mean that small quantities are harmful in any way, but that it should be treated as a medicine and given the same respect.
Most Mannitol commercially available is synthesized from Fructose.
Not usually sold on its own.
It produces a cooling effect in the mouth, which makes it particularly suitable for chewing gum and creates a refreshing
effect. It is used as a dusting powder for chewing gum. It is also used as a coating for pills. It is also commonly used as
an illicit cutting agent with drugs such as heroin and cocaine.
Approved in the USA. Approved in the EU as E421.
Conclusions and Summary:
Important sugar alcohol that has use in a large number of medical applications. It is beneficial in the production of many
processed foods and confectionery due to its unique properties. However it is of limited use as a sugar substitute. One spoon
of sugar contains 16 calories. To achieve the same sweetness it would be necessary to consume 13 calories of Mannitol, so
there is very little saving. However it has a very low glycemic index and is suitable for diabetics. It can have a laxative
effect if large amounts are ingested.
