Which is the difference between the white and raw sugar? |
|
Difference in color between the two sugars does not come from the plant used, but from the purity level of sucrose. |
Which are the physical and chemical properties of sugar? |
|
Sucrose is a disaccharide composed of one glucose and one fructose molecule.
Its molecular formula is C12H22O11, and its molecular weight is 342g/mol. Sucrose has the property to deflect polarized plane of light to the right (optical rotation is "rightward"). Very soluble in water at 0 ° C, 180 g sugar can be dissolved in 100 g of pure water. When heated to dry, it begins to melt at approximately 160 ° C, and then converted into candy before burning at 190-200 ° C, obtaining a carbon sugar residue. Under the action of temperature and pH, the sucrose solution is hydrolyzed by releasing molecules of glucose and fructose. This new blend is called "inverted sugar." |
How does sugar is made? |
|
Sugar (sucrose) is extracted from sugar beet or sugar cane. |
How does a quality sugar is determinated? |
|
To determine the quality of sugar, all countries agreed to respect the following criteria of analysis:
|
What are the special sugars? |
|
These include, for example, the "vergeoise", which is obtained by a long cooking of sugar during crystallization cycles. Its color and fragrance are the result of the formation of colored ingredients, as caramel while heating. |
Is there a deadline for sugar consumption? |
|
The crystallized sugar, is also called "sugars in solid form," are not subject to the labeling including a durability date. |
Does sugar helps to gain weight? |
|
If sugar is taken without excess sugar is not fattening. |
What is it exactly, the refined sugar ? |
|
Beet or cane sugar |
