Isomalt Shop Online


Isomalt is a sugar substitute, a type of sugar alcohol, used primarily for its sugar-like physical properties. It has only a small impact on blood sugar levels and does not promote tooth decay, i.e. is tooth-friendly. Isomalt is widely used for the production of sugar-free candy, especially hard-boiled candy, because it resists crystallisation much better than the standard combinations of sucrose and corn syrup. It is used in sugar sculpture for the same reason. Source: https://en.wikipedia.org/wiki/Isomalt
White Chocolate (Compound) Wikipedia


Compound chocolate is a product made from a combination of cocoa, vegetable fat, and sweeteners. It is used as a lower-cost alternative to true chocolate, as it uses less-expensive hard vegetable fats such as coconut oil or palm kernel oil in place of the more expensive cocoa butter. It may also be known as 'compound coating' or 'chocolatey coating' when used as a coating for candy.
