Question

Critical thinking bonus points =1 Manufacture of Liquid-Filled Chocolates. The manufacture of chocolates containing a liquid center is an interesting application of enzyme engineering. The flavored liquid center consists largely of an aqueous solution of sugars rich in fructose to provide sweetness. The technical dilemma is the following: the chocolate coating must be prepared by pouring hot melted chocolate over a solid (or almost solid) core, yet the final product must have a liquid, fructose-rich center. Suggest a way to solve this problem. (Hint: Sucrose is much less soluble than a mixture of glucose and fructose.) Critical thinking bonus points =1 Manufacture of Liquid-Filled Chocolates.

Explanation / Answer

Answer

The center core is made with semisolid slurry of sucrose and water. In this slurry mix invertase and quickly coat with the chocolate. The invertase in the core hydrolyze the sucrose into gluose and frutose.
