Ascorbyl Palmitate

Main Source

• Synthetic Preparation: Ascorbyl palmitate is usually prepared by chemical synthesis. Using ascorbic acid (vitamin C) and palmitic acid as the main raw materials, under certain catalysts and reaction conditions, the 6 - hydroxyl group of ascorbic acid undergoes an esterification reaction with palmitic acid to form ascorbyl palmitate. This synthetic method can effectively convert water - soluble ascorbic acid into a fat - soluble form, making it more suitable for applications in non - aqueous systems such as oils.

Main Functions and Applications

• Antioxidant Effect: Ascorbyl palmitate has excellent antioxidant properties and can effectively prevent the oxidative rancidity of oils and oil - containing foods. It can scavenge free radicals in oils, block the oxidative chain reaction, delay the oxidation process of oils, and extend the shelf - life of foods. It is widely used in oil - rich foods such as edible oils, fried foods, meat products, and nuts.
• Nutritional Fortification: As a derivative of vitamin C, ascorbyl palmitate can be hydrolyzed by enzymes in the human body to release ascorbic acid, thus exerting the nutritional functions of vitamin C, such as promoting collagen synthesis, enhancing immunity, and facilitating iron absorption. Therefore, it is often used as a nutritional fortifier and added to various foods to increase their nutritional value.
• Other Applications: Ascorbyl palmitate is also used in the cosmetics and pharmaceutical fields. In cosmetics, it can be used as an antioxidant to protect the skin from free - radical damage and delay skin aging. In pharmaceuticals, it can be used to prevent the oxidation and deterioration of oil components in drugs, and can also serve as a supplementary form of vitamin C.
