What is Ascorbyl Palmitate?
Ascorbyl Palmitate power, is made of palm acid and L-anti-hemogliplate. Other alias: L-Condoric acid ﹣ 6﹣ palmate, 6-O-Palm -L-L-Condoric acid. VC-palmate is an efficient and safe fat-soluble antioxidant. It is rated by the World Health Organization (WHO) Food Additives Committee as a nutritious, efficient, and safe food additive. Antioxidants in infant food permitted by "Food Additives" permitted by infant foods. It is not only used in food to play the effects of antioxidant, food (oil), and nutritional reinforcement, but also uses cosmetics.
L-ASCORBGYL PALMITE (referred to as VC ester) has efficient oxygen removal and nutritional reinforcement functions, and has the entire physiological activity of vitamin C. At the same time, it overcomes the three major shortcomings of vitamin C fear of heat, light, and tide. Vitamin C can provide vitamin C212g every 500g.
L-ASCORBGYL PALMITE (L-AP) is a new type of multi-functional food additive. Because of its unique features, it has been widely used as a fat-soluble antioxidant and nutritional enhancer. Or food. Compared with L-as-as-asctal acid, the L-asler palmate has significantly improved antioxidant properties; because of the implantation of palm acid groups, it has both hydrophilic antibody-based and liquid palm acid bases, which has become a Palmicate group, which has thus becoming becoming possible One excellent surfactant 31. In addition, Kageyamak, etc., also found that it can strongly suppress the DNA synthesis of EHRLICH ASCITES cancer cells and break down the cell membrane phospholipids of cancer cells, which is an excellent anti -cancer substance. It can be predictable that L-anti-hemoglobinate will be active as an important multi-functional additive as an emerging multi-functional additive in various fields such as food, cosmetics and medical care products.
In recent years, the application of L-AP has expanded from the field of food, grain and oil to other fields. For example, it can be used as a stabilizer in the drug ointment and capsule preparation, which is added to thermal paper to increase the stability of the paper. It is added in cosmetics to enhance its effect, and at the same time, it has antibacterial activity such as Bacillus.
At present, the production process of the L -resistant hyperthyrium palmate mainly includes a gyro chloride, sulfate and lipase method. Among them, the corrosiveness of the gum chloride method is strong: the sulfuric acid method has a long reaction time and is accompanied by a large amount of waste acid production, and the pollution is serious: the lipase method is immature.
Vitamin C introduces hydrophobic long chain in the C6 -bit hydroxyl group, reacting with palm acid reactions to generate anti -hemorrite palmate, so that it has the fat -soluble that does not have the anti -hemorrotic acid, and changes the scope of application of ascorbic acid. Antioxidants, all physiological functions and oil substances of vitamin C.
VC-palmate is white to light yellow powder. It has mild citrus aroma and is extremely difficult to dissolve in water. It is easily dissolved in ethanol, ether, animal and plant oils, and in concentrated or crystalline, the nature is very stable.
VC-Palmate-based vitamin C derivatives not only enhance the stability of vitamin C, but also retain its physiological effects. It has good free radical removal, antioxidant, anti-aging and other effects. It is widely used in oil-containing foods , Analogy, plant oil and cosmetics.
What are the benefits?
Antioxidant: It is an excellent antioxidant. In cosmetics, it is mainly used for high -grade cosmetics additives, improve product stability, and help protect the skin from liberal damage.
Whitening effect: When vitamin C inhibits tyrosinase effects, the structure of C6-bricpin hydroxyl and tyrosine active centers on the structure is closely combined with copper ions of the tyrosine active center. It makes it difficult for it to form a close combination with the type of hydrogen bonding of the tyrosine activity center, so the inhibitory of tyrosine is limited and a whitening effect is limited.
Other effects: Ascorbyl Palmite has other effects of vitamin C, which can help improve oily skin and reduce acne problems. Promote the role of collagen synthesis, which can improve skin elasticity and firmness; delay the natural aging of the skin and light aging.
1. An important use of Ascorbyl Palmitate is as an antioxidant for oils. The oxidation of oils is caused by free radicals attacking oil molecules to produce alkyl radicals. In the presence of Ascorbyl Palmitate, it can preferentially combine with free radicals to make the oil The oxidation reaction is terminated during the initiation phase.
2. When Ascorbyl Palmitate reacts directly with oxygen, metal ions such as Cu2+ and Fe3+ must be present. Hydrogen peroxide and dehydrogenated Ascorbyl Palmitate are first produced, and then hydrogen peroxide reacts with Ascorbyl Palmitate to produce dehydrogenated Ascorbyl Palmitate.
3. When Ascorbyl Palmitate is used in combination with tocopherol (vitamin E) or other antioxidants, it will show a synergistic effect. The most commonly used application solution is AP+Ve. Ve can be used in greases without limit, and AP is limited to 0.2g/kg. Tocopherol first reacts with free radicals to produce tocopherol free radicals. In the presence of Ascorbyl Palmitate, vitamin E can be regenerated and Ascorbyl Palmitate free radicals are generated until Ascorbyl Palmitate is completely consumed.
Application status at home and abroad
The United States has proposed increasing the daily intake of vitamin C per person from 60 mg to 200 mg, and its vitamin C consumption is close to 20,000 tons per year. Japan's vitamin C demand is 6,000 tons; my country's vitamin production capacity exceeded 50,000 tons in 2004, accounting for more than 60% of the world's total production capacity. However, domestic demand does not exceed 5,000 tons, and my country's per capita annual vitamin C consumption is less than 4 g. It is far lower than the per capita annual consumption of 60g and 90g in developed countries in Europe and the United States. The serious imbalance between vitamin C production and consumption in my country has made most vitamin C dependent on exports, while domestic consumption is seriously insufficient. Therefore, the potential of the domestic vitamin C market is huge. of.
With the gradual improvement of people's nutritional and health awareness, it has become a market development trend to supplement vitamin C and other nutrients through high-end nutritional products such as formula milk powder. For example, milk powder and nutritious rice noodles contain some unsaturated fatty acids, minerals, etc. In addition, ascorbyl palmitate is an indispensable and important component. In addition to supplementing the necessary vitamins for infants, it can also play an antioxidant role, prevent the unsaturated fatty acids in the product from oxidative rancidity, and improve the shelf life of the product.
L-Ascorbyl Palmitate is a new type of smart food preservative. Because of its unique effects, it has been widely used as a fat-soluble antioxidant and nutritional fortifier in vegetable oils or foods in my country. Compared with L-ascorbic acid, its antioxidant capacity is significantly improved; because of the incorporation of palmitic acid groups, it has hydrophilic ascorbic acid groups and lipophilic palmitic acid groups, thus becoming a high-quality surfactant. . In addition, KageyamaK and others also found that it can significantly inhibit the DNA production of Ehrlicascites tumor cells and dissolve the cytoplasmic unsaturated fatty acids of tumor cells, making it a good anti-cancer substance. It can be predicted that L-ascorbyl palmitate will eventually develop as an important intelligent preservative active in various industries such as food, skin care products and medical health products.
