    High Quality Calcium Ascorbate / Calcium Ascorbate Dihydrate CAS 5743-28-2

    What is  Calcium Ascorbate Dihydrate ?

    Calcium ascorbate is a mineral ascorbate, or the inorganic salt of ascorbic acid. It combines calcium (a mineral) with ascorbic acid (also known as vitamin C). The addition of calcium salts to ascorbic acid buffers the acidity of ascorbic acid, making it easier to digest the mineral salt and allow it to be absorbed into the digestive tract. Calcium ascorbate is white to light yellow crystalline powder, odorless, soluble in water, slightly soluble in ethanol, insoluble in ether. pH value of 10% aqueous solution is 6.8-7.4.

    Function

    Ascorbate calcium is a form of vitamin C that is used to prevent or treat low levels of vitamin C in people who do not get enough of the vitamin from their diets. This product also contains calcium. Most people who eat a normal diet do not need extra vitamin C. Low levels of vitamin C can result in a condition called scurvy. Scurvy may cause symptoms such as rash, muscle weakness, joint pain, tiredness, or tooth loss.
    Vitamin C plays an important role in the body. It is needed to maintain the health of skin, cartilage, teeth, bone, and blood vessels. It is also used to protect your body's cells from damage. It is known as an antioxidant.

    The Fresh foods such as fish and meat, protein deterioration will affect the freshness and taste of food, so it is necessary to prevent protein deterioration during transportation and storage.
    The preservative containing Vc-Ca can prevent the deterioration of proteins contained in fresh foods such as fish and meat, and its anti-deterioration and freshness-preventing effects are not restricted by contact methods, such as spreading or spraying on food. Or immerse the food in the chemical solution, or put the refrigerant such as ice into the solution at the same time, which is very convenient to use.
    The constant is K based on the freshness of the fish, and the K value is measured as a time-dependent index for preventing protein deterioration. The K value represents the degree of protein deterioration. The smaller the K value, the lighter the deterioration and the fresher the food.
