A review of the recent literature on crystallization of the commercial sugars (fructose, glucose, lactose, and sucrose) is presented. Once crystals start to form, their surface area increases as they grow. Although the solid–liquid equilibrium is defined by thermodynamics, kinetic factors play an important role in crystallization, and thus the prediction and control of the form of the crystals initially crystallized out from the solution is a complicated task.

It is an excellent sugar control medicine in Ayurveda.|Cloves are sugar medicine in Ayurvedic science, which help to lower the blood sugar level and prevent the complication of diabetes. There is an excess amount of sugar in the sugar vs. water ratio, thus crystals form as the water gradually evaporates (turns from a liquid to a gas).
