How to apply vitamin C palmitate?

vitamin C palmitate are among the strongest antioxidants. It can prevent the formation of lipid peroxide and delay the oxidative deterioration of animal oil, vegetable oil, fish, margarine, milk and carotenoid, and the effect is better than BHA and BHT. If it is used in combination with other antioxidants such as vE, the antioxidant effect is more significant.
vitamin C palmitate is a new type of intelligent food preservative. Because of its unique function, L-ascorbyl palmitate has been widely used as a fat-soluble antioxidant and nutritional fortifier in vegetable oils or foods in China.Compared with L- ascorbic acid, L-ascorbyl palmitate has obvious improvement in antioxidation.

Because of the embedding of palmitic acid group, it has hydrophilic ascorbic acid group and lipophilic palmitic acid group, and then becomes a high-quality surfactant 31.

In addition, KageyamaK and others also found that it can obviously inhibit the DNA production of Ehrlichascites tumor cells and dissolve the cytoplasmic unsaturated fatty acids of tumor cells, so it is a good anti-cancer substance. It can be predicted and analyzed that L- ascorbyl palmitate will eventually be active as a key intelligent preservative in all walks of life such as food, skin care products and medical care products.

vitamin C palmitate can be used as antioxidant and fat-soluble antioxidant. It is suitable for use in animal and vegetable oils and various foods. Such as stabilizing soybean oil, cottonseed oil, palm oil, unsaturated fat and hydrogenated vegetable oil.

What is the use of vitamin C palmitate?

vitamin C palmitate is a multifunctional nutritional antioxidant, which has the following main uses:
1. Antioxidant: used to prevent oil from oxidative deterioration and prolong the shelf life of food.
2. Color fixative: It can help maintain the color of food in oil and prevent discoloration caused by oxidation.
3. nutritional fortifier: providing vitamin c helps to enhance the nutritional value of food.
4. High temperature resistance: suitable for high-temperature processed foods, such as baking and frying.
5. Wide application range: it can be used for animal and vegetable oils, dairy products, cosmetics, health products, baby food, puffed food, fried food, meat products, nuts, fruits, etc.
6. Cosmetics: used for whitening and anti-oxidation, with little side effects.
When it is used, it usually needs to be dissolved in oil or ethanol and added to food in a certain proportion. The maximum dosage varies according to the requirements of different products.

How to produce vitamin C palmitate?

The manufacturing process of vitamin C palmitate：64g palmitic acid was placed in a heated dropping funnel to make it in a molten state; Put 200mI. Putting thionyl chloride into a flask, heating to make its vapor enter a reaction column filled with porcelain ring packing through a conduit, and react with palmitic acid dripped from the upper part of the column, and the unreacted thionyl chloride is condensed through a branch pipe at the upper part of the reaction column and then returned to the flask;
After the dropping of palmitic acid, the reaction was completed for 30min, and a small amount of thionyl dichloride was removed by atmospheric

distillation, The manufacturing process of vitamin C palmitate is fine.and 58.6g of colorless transparent liquid was collected by vacuum distillation at 150 ~ 152℃ (2 ~ 3 kPa), with a yield of 86% (calculated by palmitic acid). Add 26.5 ml of the flask. Dimethylformamide, introducing 2g HCl gas at 0 DEG C,Then 9.69g of crystalline ascorbic acid and 13.3mL were added. Dichloromethane, at which time the reaction liquid is clarified; 15.2mL palmitoyl chloride was slowly dropped at 0℃, and reacted for 18 hours after dropping, and then heated to 20℃ for 30min. Add the reactant to 100mL. Ethyl acetate and 200mL. Stir and wash in water for 2 hours, then wash with water (50mL×3) for 3 times after suction filtration, and vacuum dry at 50℃ for 18 hours to obtain 17.5g of white powder with a yield of 84.3%.
vitamin C palmitate is obtained by esterification of palmitic acid with L- ascorbic acid.
