Recorded as a pharmaceutical excipient in many countries
Recorded as a pharmaceutical excipient by the United States Pharmacopoeia (USP) and the British Pharmacopoeia (BP). The world's first choice antioxidant for infant formula (milk powder, complementary food).
---Application---
Application-Food
1. Antioxidant:
Ascorbyl palmitate ranks among the most efficient fat-soluble antioxidants.
Effectively prevents oil oxidation--it is much better than BHA and BHT in terms of oxidation and deterioration. It has a synergistic effect and works better when used with other antioxidants such as vitamin E. In high-temperature applications, AP is better than TBHQ.
Fried products, prevent oil rancidity, extend shelf life, etc. (such as instant noodles, potato chips, fried fish, fried and grilled products, etc.)
Infant dairy products, prevent baby milk powder from oxidation and deterioration;
2. Color fixative:
Ascorbyl palmitate can be used to protect natural pigments such as capsanthin, lycopene,
carotene, lutein, etc. from oxidation.
3. Ascorbyl palmitate is a fat-soluble vitamin derivative, often used as a food additive to provide antioxidant preservation and improve food quality. Its specific applications in the food industry are as follows:
4. Ascorbyl palmitate has strong antioxidant properties, which can extend the shelf life of food, reduce the oxidation reaction of fat and oily foods, and prevent food from spoiling. Edible oils and fats
5. Ascorbyl palmitate is often added to edible oils and fats to extend their shelf life and stability, and reduce the negative effects of oil oxidation, such as odor and color changes. Dairy products
6. Ascorbyl palmitate is also used in dairy products such as milk powder and cheese to prevent fat oxidation and extend shelf life.
FOOD-Cases
• Vitamin C has the effects of strengthening gluten, anti-oxidation and nutritional supplement in baking, but because Vc is water-soluble and has poor temperature resistance, it loses significantly during high-temperature baking. It is impossible to guarantee that the peroxide value of the product does not exceed the standard, and VC nutritional supplements will be lost in large quantities and cannot reach the nominal dose.
• In order to improve the stability of vitamin C, vitamin C and palmitic acid are esterified under the action of lipase to generate fat-soluble vitamin C that can be soluble in oil, which is ascorbyl palmitate (AP).
• AP has all the physiological activities of vitamin C. Due to its fat solubility, it is more stable and has higher bioavailability than vitamin C. AP is more widely used than vitamin C in the baking industry.
Baking application cases (AP multifunctional nutritional antioxidant)
Application of AP in baking fats
AP is mainly used as an antioxidant, color preservative, and color fixative in baking fats because it is stable, high temperature resistant, and safe. It can be used in combination with vitamin E to achieve better synergistic effects. AP is better than TBHQ in high temperature applications.
Benefits of using AP in bread products:
1. Increase water absorption (up to 4%)
2. Improve dough strength and processability
3. Soften bread crumbs
4. Increase bread volume
5. Reverse the harmful effects of defatted soy flour protein
6. Have a good moisturizing and softening effect
AP has 3 hydroxyl groups (-OH) in its molecular structure, which are hydrophilic groups and have a certain water retention effect. It is often used in long-lasting bread products
Application-Cosmetics
• Whitening
① Inhibit tyrosinase activity and inhibit melanin production.
② Reduce the melanin that has been produced and lighten the skin color.
• Antioxidant
Regulate oxidative stress, react with various reactive oxygen species, and inhibit the production of reactive oxygen species.
• Anti-inflammatory
① Regulate endoplasmic reticulum stress, microglia, and inhibit the production of inflammatory factors
② Regulate lipoxygenase activity
• Improve the inflammatory microenvironment
• Inhibit hyaluronidase activity
Vitamin C palmitate. It is a vitamin C derivative esterified with ascorbic acid and palmitic acid. It not only enhances the stability of vitamin C, but also retains its physiological activity. It has good free radical scavenging, anti-oxidation, anti-aging, anti-inflammatory and other effects. It can be widely used in food, cosmetics, health products, pharmaceutical excipients and other fields.
AP is non-toxic to the human body and is the only antioxidant permitted by my country's "Food Additives Hygiene Standards" that can be used in infant food.
Currently, there are about 22,000 cosmetics with AP ingredients. AP retains the reducing group of ascorbic acid in its structure.
Due to the introduction of fat-soluble palmitic acid chains, the binding ability of AP with hydrophobic groups in the body is increased, which can effectively terminate the chain reaction of free radicals and show good antioxidant and anti-inflammatory effects.
The American Cosmetic Ingredient Evaluation Association (CIR) has recognized it as a raw material with UV protection and whitening effects.
Application-Health Products
Dietary Supplement/Nutritional Enhancer:
Ascorbyl palmitate is a fat-soluble form of vitamin C that is more easily used by the body than other forms of vitamin C. It is also more stable than most forms of vitamin C when exposed to air or light. This makes it easier for the body to absorb this form of vitamin C.
In addition to its excellent antioxidant effect and stability, AP also has nutritional value such as scavenging free radicals, preventing cell oxidation, promoting collagen synthesis, and promoting iron absorption. It is truly a "new generation of nutritional antioxidants".
