Ascorbic acid Bulk Powder

What is Ascorbic acid Powder?

Ascorbic acid Bulk Powder， vitamin C, is a very important biologically active substance. The ascorbic acid that exists in nature is mainly L-ascorbic acid, while the content of D-ascorbic acid is very small. When used in food, D-ascorbic acid is not used as a vitamin but is added to food as an antioxidant. L-ascorbic acid is a highly water-soluble compound that is highly polar, acidic and reducible. These properties are determined by the conjugation of 2,3-enediol and the lactone ring carbonyl group in its structure. Ascorbic acid is mainly found in fruits and vegetables as L-ascorbic acid, and in smaller amounts in animal tissues and animal processed products.

Ascorbic acid has strong reducing properties, so it is a commonly used antioxidant in food. It is widely used as a food additive. For example, the reducing properties of ascorbic acid are used as an improver in bread to reduce o-quinone compounds, thereby effectively inhibiting enzymatic processing. Browning. Because ascorbic acid has strong antioxidant activity, it is often used to protect substances that are easily oxidized, such as folic acid. In addition, ascorbic acid can also scavenge singlet oxygen, reduce oxygen- and carbon-centered free radicals, and regenerate other antioxidants (such as tocopherol free radicals).

Ascorbic acid is sensitive to heat, acid, alkali and oxygen and is easily soluble in water. It can easily leach out of cuts or damaged surfaces of food through diffusion or penetration processes, causing losses during thermal processing. Increasing the surface area, water flow rate and water temperature can greatly increase the loss of ascorbic acid in food. However, in processed foods, the most serious loss of ascorbic acid is chemical degradation. Fruit products rich in ascorbic acid, for example, often suffer from vitamin loss and color changes due to non-enzymatic browning.

Physical and chemical properties

Ascorbic acid in nature has two configurations, namely L configuration and D configuration, the latter has no biological activity. There are two isomers of L-configuration ascorbic acid, namely the dehydrogenated form and the reduced form, both of which have biological activity.

Vitamin C is an acidic polyhydroxy compound containing 6 carbon atoms and has a distinct sour taste; the pure product is white crystal, easily soluble in water, slightly soluble in ethanol, and insoluble in non-polar organic solvents; vitamin C is stable in acidic environments , is unstable in aerobic, heat, light and alkaline environments. When vegetables are processed and cooked under alkaline conditions, vitamin C is obviously destroyed. Acidic conditions, refrigeration, and oxygen isolation can delay the loss of vitamin C in food. Oxidase is generally more abundant in vegetables, especially cucumbers and cabbages, but less in citrus. Therefore, vitamin C is lost to varying degrees during the storage process of vegetables; but in plants, especially jujubes and prickly pears, Other fruits contain bioflavonoids, which can protect the stability of vitamin C in food.

Physiological function

Ascorbic acid Bulk Powder has the most extensive physiological effects in the human body, which is closely related to its structure and characteristics. Due to this characteristic, it has a variety of related physiological meanings and health values.

(1) Reduction effect

In the human body, vitamin C has two isomers - the oxidized form and the reduced form. The two are isomerized through oxidation and reduction, and can serve as both a hydrogen donor and a hydrogen acceptor. During the oxidation-reduction reaction in the body play an important role in.

1. Promote iron absorption. Vitamin C can reduce difficult-to-absorb ferric iron (Fe3+) into easily-absorbable divalent iron (Fe2+), promoting iron absorption; vitamin C is an important auxiliary drug in the treatment of iron deficiency anemia.

2. Promote the formation of tetrahydrofolate. Vitamin C can reduce inactive folic acid to physiologically active tetrahydrofolate, allowing it to exert physiological effects, so it can prevent and treat megaloblastic anemia.

3. Promote antibody formation. Antibody molecules contain a considerable number of disulfide bonds (-S-S-). These disulfide bonds are composed of 2 cysteine, so cysteine is required for synthetic antibodies. Higher concentrations of vitamin C can promote the reduction of cystine in food to cysteine and promote the formation of antibodies.

4. Maintain the activity of thiol enzymes. Various thiol-containing alcohols in the body require -SH to play a catalytic role. Ascorbic acid Bulk Powder can maintain the -SH in the enzyme molecule in a reduced state, thereby maintaining the activity of the enzyme.

(2) Participate in hydroxylation reaction

Vitamin C participates in the important hydroxylation reaction in the body, which is a key process in the metabolism of many important substances in the body, such as the synthesis of collagen and neurotransmitters, and the transformation of organic drugs or poisons. Therefore vitamin C has the following functions:

1. Participate in collagen synthesis

Collagen is an important component of connective tissue, and vitamin C is involved in the synthesis of collagen.

2. Promote the conversion of cholesterol into bile acids

Vitamin C promotes the hydroxylation process of cholesterol into bile acids. When vitamin C is lacking, the conversion of cholesterol into bile acids is reduced, causing cholesterol to accumulate in the liver and blood cholesterol concentration to increase. Therefore, patients with high cholesterol should supplement adequate amounts of vitamin C.

3. Promote neurotransmitter synthesis

When vitamin C is lacking, the synthesis of certain neurotransmitters will be affected.

4. Enhance detoxification of drugs or poisons

Pure ascorbic acid powder can increase the activity of mixed functional oxidase, catalyze an important reaction in biological transformation - the hydroxylation process of drugs or poisons on the endoplasmic reticulum, and enhance the detoxification process of drugs or poisons.

(3) Others

1. Detoxification

A large amount of vitamin C can alleviate the toxicity of certain heavy metal ions such as Pb, Hg, Cd, As, etc. to the body, so it is considered to have a certain detoxification effect. Mainly through two aspects: on the one hand, the oxidized glutathione (GSSG) in the body is reduced to reduced glutathione, and then combined with heavy metal ions to form a complex and excreted from the body; on the other hand, vitamin C can be combined with metal ions to form a complex. Excreted in urine.

2. Prevent cancer

Research shows that vitamin C can block the synthesis of carcinogen N-nitroso compounds and prevent cancer.

3.Scavenge free radicals

As a water-soluble antioxidant, it works synergistically with fat-soluble antioxidants to scavenge free radicals and prevent lipid peroxidation; at the same time, it can prevent and delay the oxidation of vitamin A, vitamin E and unsaturated fatty acids.

Vitamin C can reduce tocopherol free radicals to generate tocopherol; it can reduce blood cholesterol levels, prevent the occurrence of atherosclerosis, and maintain the normal function and health of the cardiovascular system.

Pure ascorbic acid powder has two mechanisms for skin whitening:

1. Reduce the dark oxygen melanin produced during melanin production into reducing melanin.

The color of melanin is determined by the quinone structure in the melanin molecule. Vitamin C has the property of a reducing agent and can reduce the quinone structure into a phenolic structure.

2. Participate in the metabolism of tyrosine in the body, thereby reducing the conversion of tyrosine into melanin.

Application of ascorbic acid in skin care products

Ascorbic acid often plays an important role in skin care products.

Hydrating essence

They are often formulated with stabilized ascorbic acid to ensure the effectiveness and long-term stability of the ingredients.

At the same time, ascorbic acid can penetrate deep into the skin, providing powerful antioxidant, whitening and collagen synthesis effects.

Antioxidant Creams and Lotions

Suitable for full face care, these products provide long-lasting antioxidant and hydration benefits.

They generally have a lightweight texture, are easily absorbed, and are suitable for use on all skin types.

Facial mask

These masks are rich in ascorbic acid, which deeply nourishes and repairs the skin, brightens the complexion, and reduces the appearance of fine lines and discoloration.

Using a mask allows ascorbic acid to be better absorbed into the skin for optimal results.

eye cream

The skin around the eyes is thin and easily damaged, so ascorbic acid eye cream can provide specialized care to reduce the appearance of fine lines, dark circles and bags under the eyes.

They often have gentle formulas that won't irritate the sensitive skin around the eyes.

In addition, ascorbic acid can also be used in combination with other ingredients and formulas, such as hyaluronic acid, vitamin E, fruit acids, etc., to exert a synergistic effect and enhance skin repair and care effects.
