30 [57-30-1][1] Sucrose is β-D-fructofuranosyl-α-D-glucopyranoside
.

Sucrose is colorless crystal or white crystalline loose powder
.

Sucrose is easily soluble in water, slightly soluble in ethanol, and almost insoluble in absolute ethanol
.

The specific rotation of this product is taken, accurately weighed, dissolved in water and quantitatively diluted to make a solution containing about 0.
1g per 1ml, which is determined according to the law (General Rule 0621).

[Identification] (1) Take this product, add 0.
05mol/L sulfuric acid solution, after boiling, neutralize it with 0.
1mol/L sodium hydroxide solution, add alkaline copper tartrate test solution, and heat to form a red color of cuprous oxide precipitation
.

　　(2) The infrared absorption spectrum of this product should be consistent with that of the sucrose reference substance (general rule 0402)
.

　　[Check] The color of the solution is to take 5g of this product, add 5ml of water to dissolve, if the color develops, it should not be darker than the yellow No.
4 standard colorimetric solution (general rule 0901 first method)
.

Sucrose is a kind of disaccharide.
It is formed by the condensation and dehydration of a molecule of glucose hemiacetal hydroxyl group and a molecule of fructose hemiacetal hydroxyl group.
Sucrose is sweet, odorless, soluble in water and glycerol, slightly soluble in Alcohols are optically active, but have no variable optical rotation
.

Sucrose is found almost universally in the leaves, flowers, stems, seeds and fruits of the plant kingdom, especially in sugar cane, sugar beet and maple sap
.

Sucrose has a sweet taste and is an important food and sweet condiment
.

Divided into white sugar, brown sugar, soft white sugar, rock sugar, coarse sugar (brown sugar)
.

Sucrose is generally divided into: white granulated sugar, yellow granulated sugar, brown granulated sugar, soft white sugar, monocrystalline rock sugar, polycrystalline rock sugar, brown sugar, brown sugar, borneol, cube sugar, icing sugar, liquid syrup, etc.
Among them, monocrystalline rock sugar with high purity is used.
Widespread is white granulated sugar
.

Sucrose is a disaccharide, the main component of table sugar
.

Under the action of heat, acid, alkali, yeast, etc.
, sucrose and sucrose solution will produce various chemical reactions
.

The result of the reaction not only directly causes the loss of sucrose, but also produces some substances that are harmful to sugar production
.

Crystallized sucrose is heated to 160°C, it will be thermally decomposed and melted into a thick and transparent liquid, and it will recrystallize when cooled
.

When the heating time is prolonged, the sucrose is decomposed into glucose and de-fructose
.

At a higher temperature of 190-220 ° C, sucrose is dehydrated and condensed into caramel
.

Further heating of the caramel produces products such as carbon dioxide, carbon monoxide, acetic acid and acetone
.

Under humid conditions, sucrose decomposes at 100°C, releasing water and turning black in color
.

When the sucrose solution is heated and boiled under normal pressure for a long time, the dissolved sucrose will be slowly decomposed into the same amount of glucose and fructose, that is, the transformation will occur
.
