Natural birch sugar is also used in the food industry. It has the symbol E967 and is added to candies, chewing gums, liqueurs and sweet sauces. This sweetener can also be found in jams, confectionery products, creams for bread, desserts and cocoa-containing sweets. Interestingly, it is also sweetened with mustards and frozen fish. Xylitol can be used as a healthy and less caloric substitute for traditional sugar. It is just as good at sweetening all drinks, pastries, desserts and other dishes. It is not only sweetened with yeast dough, because it inhibits the growth of yeast.
