Sodium ascorbate is an organic sodium salt resulting from the replacement of the proton from the 3-hydroxy group of ascorbic acid by a sodium ion. The chemical formula C6H7O6Na, white to yellowish white crystalline powder or particles, odorless, slightly salty taste. The decomposition temperature is 218℃, it is stable in the dry state, the color is deepened in the light, and it is slowly oxidized and decomposed after moisture absorption and in aqueous solution. It is more soluble in water than ascorbic acid. It has a role as a food antioxidant, a flour treatment agent, a coenzyme, a plant metabolite, a human metabolite, a Daphnia magna metabolite and a reducing agent.
What are the effects?
Antioxidant
Sodium ascorbate is a form of vitamin C that has sodium components that help lower its acidity levels. The sodium content helps vitamin C to be easily absorbed and stay longer in the body. It serves as an antioxidant that helps keep your cells from damage and keep them healthy.
Maintaining physical fitness and prevent cardiovascular and other diseases
Getting enough vitamin C can lower your risk of developing some cancers, as well as cardiovascular disease. It can also protect you from eye-related diseases and shorten the duration and severity of the common cold. It builds collagen, which slows outward signs of aging, and also maintains strong bones, joints and tendons.In some health situations, supplements like sodium ascorbate have proven to be effective when combined with dietary sources of vitamin C.
Protect against gout attacks
Gout is a type of arthritis. Gout symptoms appear when there is too much uric acid in the blood. Uric acid is a waste product produced by the body. At high levels, it may crystallize and deposit in the joints. ,Several studies have shown that vitamin C may help reduce uric acid in the blood and, as a result, protect against gout attacks.
Enhance cell matabolish and skin recovery
Sodium Ascorbate is a potent antioxidant. In addition, it works well in synergy with other free radical scavenging molecules like tocopherols (vitamin E), protecting cell membranes, and other structures from oxidative stress and UV-induced damage. In addition, sodium Ascorbate exhibits all beneficial effects of L-Ascorbic acid on the skin, including boosting collagen production, suppressing melanin synthesis, and enhancing cell metabolism and skin recovery. It is a perfect anti-aging ingredient with many benefits for the skin's healthy, smooth, and bright appearance.
Application:
Food preservation and Antisepsis
Sodium ascorbate has antioxidant effects and can be converted into vitamin c in the body. In the food industry, sodium ascorbate is usually used for preservation and antisepsis, which can effectively prevent the generation of carcinogenic nitrite amine in pickled food. In addition, sodium ascorbate can also remove the discoloration, odor and turbidity of food and beverage, and is widely used in meat, fish, vegetables, fruits, beverages and canned preservative preservation.
Baking industry
In baking, it can either be added to the flour at the mill or to the dough at the bakery. The two main benefits of sodium ascorbate in bakery systems are its role as: Dough conditioner and Flour improver. This ingredient serves several purposes in baked goods:Antioxidant and reducing agent: by reacting with free radicals it produces inactive compounds that disrupt free radical chain reactions; Dough conditioner: stabilizes the gluten network by reducing extensibility and increasing elasticity; Acidity regulator: contributes to acidity regulation unlike ascorbic acid that tends to increase dough acidity; Bread improver: helps improve volume, shape and texture of baked goods; Taste: provides a desirable tart flavor in candies and fruit juices.
Nutrient industry
The function of Sodium ascorbate is same as Ascorbic acid. It is essential for human health mainly to prevent common cold, infections and gum disease and in maintaining proper immune function. One concern with this ingredient is its sodium content which may have undesirable consequences such as water retention, hypertension, kidney and heart disease.
Cosmetic industry
The main role of sodium ascorbate in cosmetics and skin care products is an antioxidant, the risk coefficient is 1, is relatively safe, can be assured to use, generally has no effect on pregnant women, sodium ascorbate does not cause acne. Sodium ascorbate is a salt of vitamin C, water soluble and easily absorbed by the skin. It is often used as a skin conditioner and antioxidant in cosmetics. Sodium ascorbate is suitable for 6 types of skin: firm skin, tolerant skin, dry skin, oily skin, wrinkled skin, pigmented skin.
Industrial production
Sodium ascorbate can be industrially produced by two methods: reacting ascorbic acid with sodium bicarbonate, and via gulonic acid.
Ascorbic acid and sodium bicarbonate method:
Reaction: ascorbic acid is dissolved in water followed by addition of alkaline sodium bicarbonate.
Solvent addition: to precipitate sodium ascorbate.
Filtration: resulting sodium ascorbate is filtered and washed with a small amount of solvent.
Drying: the obtained salt is air-dried.
Difference between Ascorbic acid and Sodium ascorbate
Ascorbic acid is the purest kind of vitamin C. On the other hand, another kind of vitamin C is sodium ascorbate which contains vitamin C attached to minerals. Ascorbic acid is by far one of the known forms of vitamin C. It is a water-soluble vitamin that helps keep our skin, hair, and bones healthy. Most fruits and vegetables contain ascorbic acid, and its drug form helps treat those who have vitamin C deficiency, scurvy, delayed wound, and bone healing.
