What Factors Are Related to the Sweetness of Maltitol?

Maltitol is a low-calorie sugar substitute with great potential in the field of sugar substitutes:

1. Low calories: The calories of maltitol are only 10kJ/100g, which is about 5% of the calories of sucrose. It is difficult to be decomposed by saliva, gastric juice, small intestinal membrane enzymes, etc. in the human body. Except for a part that can be used by intestinal bacteria, the rest cannot be digested and excreted from the body. This makes it an ideal sweetener choice for people who pay attention to calorie intake. It can be used to produce low-calorie foods to help people reduce calorie intake while enjoying sweetness.

2. Appropriate sweetness: The sweetness of maltitol is 80%-90% of sucrose, with a soft and non-irritating flavor, which is very close to the sweetness and taste of sucrose. Compared with some other sugar substitutes, maltitol can better simulate sucrose in providing sweetness and can meet consumers' demand for sweetness. When used in food and beverages, it can replace sucrose as a sweetener without changing the taste and flavor of the product.

The sweetness of maltitol is mainly related to the following factors:

1. Structure: The chemical structure of maltitol determines the basic properties of its sweetness. It is a disaccharide alcohol made by hydrogenation and reduction of maltose. Its molecular structure has a certain similarity with sucrose, which enables it to bind to sweet taste receptors in a specific way, thereby producing sweetness, and its sweetness is about 80%-90% of sucrose.

2. Concentration: Generally speaking, the higher the concentration of maltitol solution, the more obvious the sweetness. However, the increase in sweetness is not a simple linear relationship with concentration. When the concentration reaches a certain level, the growth rate of sweetness will gradually slow down.

3. Temperature: Temperature has a certain effect on the sweetness of maltitol. Within a certain temperature range, the sweetness of maltitol will increase slightly as the temperature rises. But when the temperature exceeds a certain value, the sweetness may decrease. This is because temperature changes affect the movement of maltitol molecules and their ability to bind to sweet taste receptors.

4. Solvent: Maltitol may have different sweetness when dissolved in different solvents. For example, in aqueous solution, the sweetness of maltitol is relatively stable; in some organic solvents, due to the interaction between the solvent and the maltitol molecules, its molecular conformation may be changed, thereby affecting the sweetness.

5. Synergistic effect of other substances: In the food system, when maltitol coexists with other sweeteners, flavor substances, acids, salts and other substances, a synergistic effect will occur, thereby affecting its sweetness perception. For example, when used in combination with certain sweetness enhancers, the sweetness effect can be significantly improved; while some acidic substances may reduce the sweetness of maltitol.
