Maltose definition - Maltose is a disaccharide made of two molecules of a monosaccharide called glucose.
Maltose safety - maltose is probably safer than other commonly used sugars like sucrose, glucose, high fructose corn syrup and fructose. Fructose is known to be a risk factor for metabolic disorders like obesity. Maltose does not contain fructose and it releases glucose more slowly than glucose, which is desired. Glucose is not as bad as fructose but ingestion of it results in an immediate impact on your metabolic system and demands high output of insulin to handle it, which is not a good thing. Compared to glucose, maltose breaks down to become glucose relatively slowly (of course the most friendly sugar is starch) and our system can handle it relatively easily.
Maltose benefits - Some claim that maltose can prevent some digestive problems. The best maltose can offer is that is can be used as a replacement for other sugars and reduce the risk of obesity and metabolic syndrome. However, at this time, maltose is not commonly used as a sweetener in the food and beverage industry. Maltose is pricey compared to high fructose corn syrup or even sucrose. The price may be the main reason that the industry is reluctant to use it. Maltose is a reducing sugar, which makes it reactive with many other components. But glucose and fructose are more reactive than maltose.
