Rock candy or sugar candy, [1] also called rock sugar, or crystal sugar, is a type of confection composed of relatively large sugar crystals. In some parts of the world, local variations are called Misri , nabat [ 2 ] or navat .
Sugar glass is made by dissolving sugar in water and heating it to at least the "hard crack" stage (approx. 150 °C / 300 °F) in the candy making process.Glucose or corn syrup is used to prevent the sugar from recrystallizing and becoming opaque, by disrupting the orderly arrangement of the molecules.
At this point seed grain is added to serve as nuclei for sugar crystals, and more syrup is added as the water evaporates. The growth of crystals continues till the vacuum pan is full. [20] The crystals and the mother liquor (molasses) now form a dense mass known as massecuite. [21]
Brown sugar starts off much the same as white sugar (i.e., it comes from the cane) but instead of being completely refined, some molasses is retained and mixed in with the white sugar crystals ...
Additionally, take the time to make sure the sugar is thoroughly melted and dissolved before you move on to the next step. Otherwise, you guessed it, crystals can form. 2.
The sugar syrup is concentrated by boiling and then cooled and seeded with sugar crystals, causing the sugar to crystallize out. The liquor is spun off in a centrifuge and the white crystals are dried in hot air and ready to be packaged or used. The surplus liquor is made into refiners' molasses. [97]
Confectionery can be mass-produced in a factory. The oldest recorded use of the word confectionery discovered so far by the Oxford English Dictionary is by Richard Jonas in 1540, who spelled or misspelled it as "confection nere" in a passage "Ambre, muske, frankencense, gallia muscata and confection nere", thus in the sense of "things made or sold by a confectioner".
With the aim of neutralizing the juice, which facilitates the formation of sugar crystals, lime or sulfur dioxide are added. In some of the larger factories the juice is filtered and chemically clarified. Boiling, typically in open pans, either in a single pan or in a series of pans placed above a furnace, is how water gets evaporated.
