|Basic properties||Vitamin C is also called Ascorbic Acid. It is easily dissolved in
water, slightly dissolved in ethanol and not soluble in some
organic solvent like chloroform, benzene, diethyl ether and grease.
It has acidity and reducibility.|
Vitamin C is a white crystal or crystalline powder. Its melting
point is 190℃～192℃, no odour and sour taste. It is easily dissoved
in water, slightly dissovled in ethanol and not dissovled in
chloroform and diethyl ether. Vitamin C is a kind of soluble
vitamin and has very strong reducibility. It is easy to break down
when heat or in the solution. And it is easier to be oxidized in
alkaline conditions. Vitamin C in food is absorbed by the upside of
small intestine. Once absorbed, it will spread in to the soluble
stuctures of the body.

Recommendation On Use
Vitamin C can be used in wheat flour and its maximum usage is
It also can be used in Concentrated fruit and vegetable juice and
the usage should be according the requiremens of the production.
Vitamin C is used in fruit juice and carbonate beverages for
prevent from going oxidative deterioration. Theoretically every
3.3mg Vitamin C can react with 1ml air. If the average assay of the
air in the bottom clearance of the container is 5ml, 15-16g Vitamin
C will make the oxygen assay in air be lower than critical level.
And then prevent the products from discoloring and off-odor. Citric
Acid can be used as synergist when Vitamin C was used as
25kg/carton or according to the requests of the customers.
Store in a tightly closed container and a cool, dry place under an
inert atmosphere. Do not store in direct sunlight.
