When sugar is added to water, sugar solutions is formed which is homogenous solution. Sugars are soluble in water and readily form syrups. If waters is evaporated, crystals are formed.
When sugar concentrated into syrup, it resist bacteria and prevents fermentation. Concentrated sugar solutions – syrups are susceptible to molds, but molds are much slower to attack foods than are bacteria.
Sugars form molecular solutions due to hydrogen-bond interchange. When sugar is placed in water the water molecules form hydrogen bonds with the sugar molecules, thus hydrating them and removing them from the sugar crystals.
The solutions needs to be boiled in order to reach the desired sugar concentration to produce a sugar syrup.
As the sugar boiled water evaporates and the solution becomes saturated. When the saturated solution is called it became supersaturated and easily precipitates sugars.
The concentration of sugar solutions can be measured using a hydrometer, refractometer, or flowmeter.
The concentrations measured by these instruments is converted into a degrees brix value, which is the food industry’s standard of identifying the sugar concentration in syrups or liquids.
Each degree (1 °) of Brix is equal to a 1% concentration of sugar in solution when measured at 20 ° C.
