Two of the major bottlenecks for further product development are partly the insolubility of cocoa in water and the unpredictable rheology of cocoa in an aqueous environment. Water boils at 100 C (212 F). And no, it does not matter if you heat it. The molecules get further apart in the solvent, but they don't change. - 16517350 It is obvious to one who does a great deal of cooking that a sugar that requires 6 pounds of water to dissolve 1 pound of sugar, could not be used for concentrated sugar products like jellies, jams, frostings, or even cakes.. Sucrose. These hydroxyl groups make the molecule very polar and easily slip into water, which is a polar solvent. Using a wooden spoon, stir the sugar and water continuously until the granules begin to dissolve and the mixtures starts to simmer. It depends a lot on the hydrogenated nature of the oils. Why can sugar dissolve in cooking oil? b. Oil molecules do not contain any charge. Does salt dissolve faster in hot than in cold water? The Art & Science of Bean to Bar Chocolate. Ta da. Plus the thought that cold liquids dissolve like hot liquids, just slower is not correct. Essentially, I was following a recipe written by a pot head and the note that sugar didn't dissolve into oil was at the bottom. Are we done? The point of this experiment, in addition to learning whether salt or sugar dissolves faster in various liquids, is to learn how molecules interact in a solution. Just because the cocoa butter (or shortening or dairy butter) is melted and in a liquid state does not make it equivalent to water. It easily dissolves in water because the molecule is made up of rings with lots of hydroxyl (-OH) groups sticking off the sides. The sugar molecules are known to have hydroxyl groups that have a slight negative charge. The two groups tend to hang together with either other singles or other couples. Its color shifts from white to amber before taking on a brown hue, and its sweet taste is replaced by a more bitter flavor. 5. When I do use it (it’s great for dusting cake and torte pans with) I’ve used Dagoba’s. Use chemistry: add enough water to dissolve the sugar, then mustard (it is a surfactant).
