Invertase

Invertase (EC 3.2.1.26 ) (systematic name: beta-fructofuranosidase) is a sucrase enzyme. It catalyzes the hydrolysis (breakdown) of sucrose (table sugar) to fructose and glucose, usually in the form of inverted sugar syrup.

For industrial use, invertase is usually derived from yeast. It is also synthesized by bees, who use it to make honey from nectar.

Invertase is expensive, so when fructose is required, it may be preferable to make it from glucose using glucose isomerase.

Chocolate covered cherries include invertase, which liquifies the sugar inside. Once the candy is manufactured, it needs at least a couple of weeks in storage so that the invertase can begin to do its work. This information came from a site I found last year that was hosted by a candy manufacturer.
