What is Ascorbyl Palmitate Powder?

Ascorbyl Palmitate Powder, likewise called ascorbyl-6-palmitate, ascorbyl palmitate, is a white or yellowish-white powder with a minor citrus odor. my nation’s “Hygienic Requirement for making use of Food Additives” states that Ascorbyl Palmitate Powder can be used in edible oils and likewise fats, oil-containing foods, immediate noodles, as well as additionally bread, along with the optimum usage quantity is 0.2 g/kg.
Ascorbyl Palmitate Powder is a brand-new sort of smart food preservative. Due to its unique effect, it has actually been frequently used as a fat-soluble anti-oxidant and also dietary fortifier in vegetable oils or food. Compared to L-ascorbic acid, L-ascorbyl palmitate has a significant restoration in anti-oxidation; due to the insertion of palmitic acid groups, it has a hydrophilic ascorbic acid group and likewise a lipophilic palmitic acid group, which consequently becomes a kind of Costs Surfactant 31. Additionally, KageyamaK et al. in addition uncovered that it can substantially prevent the DNA manufacturing of Ehrlichascites tumor cells, and additionally liquify the cytoplasmic unsaturated fatty acids of lump cells, which is an outstanding anti-cancer compound. With the ability of anticipating analytics, Ascorbyl Palmitate Powder will become energetic as a critical clever chemical for success in a choice of markets containing food, skincare and additionally health care.

Ascorbyl Palmitate Powder Uses

  1. Ascorbyl Palmitate Powder can be used in oil-containing food, edible oil, animal as well as grease and advanced cosmetics, as well as in numerous infant food and also milk powder, with antioxidant and nutritional strengthening features. Oxygen impact is extremely apparent as well as heat resistance, ideal for medication, healthcare products, cosmetics, and so on, as well as is suitable for anti-oxidants in cooking and also frying oils. The antioxidant impact of lard is better than vegetable oil.
  2. Ascorbyl Palmitate Powder is among the greatest anti-oxidants. It can stop the formation of lipid peroxides and postpone the oxidative wear and tear of animal oils, veggie oils, fish, margarine, milk and also carotenoids, and also the effect is better than BHA as well as BHT. If used in mix with various other anti-oxidants such as vE, the antioxidant result is more considerable.
  3. Ascorbyl Palmitate Powder is made use of as an antioxidant and also can be used in oil-containing foods, instant noodles, edible oils and hydrogenated vegetable oils with a maximum dose of 0.2 g/kg; it can also be used in infant formula with an optimum dose of 0.01 g/kg (ascorbic acid in fats as well as oils). count). Furthermore, it is likewise made use of as a food nutrition fortifier (refer to vitamin C for dose).
  4. Ascorbyl Palmitate Powder boosts collagen synthesis, visibly raises skin elasticity, anti-oxidants in vivo as well as anti-oxidants artificial insemination.
  5. Ascorbyl Palmitate Powder as a preservative. Mostly utilized as dietary fortifier as well as antioxidant preservative, it is extensively made use of in food as well as beverage and various other fields.

Limited use of Ascorbyl Palmitate Powder

FAO/WHO (1984): Formulated baby food 10mg/L (ready-to-drink products for all types of formulated baby food); canned baby food, cereal-based processed children’s food 200mg/kg fat; margarine and general edible oils 200mg/kg kg (used alone or in combination with Ascorbyl Palmitate Powder).
According to FAO/WHO (1987): antioxidant of various oils, 500mg/kg. USDA (9CFR§318.7, 2000): Margarine 0.02%.
GB14880-94: Same as “01001, L-ascorbic acid”.
GB2760–2001 (g/kg): oil-containing food, instant noodles, edible oil, hydrogenated vegetable oil, bread, 0.2; infant formula food 0.01 (calculated as ascorbic acid in oil).


Put 64 g of palmitic acid in a heated dropping funnel to make it molten; 200 ml. Put thionyl chloride into the flask, heat it to make its vapor enter the reaction column with ceramic ring packing through the conduit, react with the palmitic acid dripped from the upper part of the column, and the unreacted thionyl chloride is condensed through the branch pipe on the upper part of the reaction column Then return to the flask; after the dropwise addition of palmitic acid, the reaction is carried out for 30min, a small amount of thionyl chloride is removed by atmospheric distillation, and 150~152 ℃ (2~3kPa) fraction is collected by vacuum distillation as a colorless transparent liquid 58.6g, and the yield is 86% ( as palmitic acid).

Add 26.5 mL to the flask. In dimethylformamide, 2 g of HCl gas was bubbled at 0°C, then 9.69 g of crystalline ascorbic acid and 13.3 mL were added. Dichloromethane, the reaction solution was clear at this time; 15.2 mL of palmitoyl chloride was slowly added dropwise at 0 °C, and the reaction was performed for 18 h after the dropwise addition, and then the temperature was raised to 20 °C for 30 min. The reaction was added to 100 mL. ethyl acetate and 200 mL. The mixture was stirred and washed in water for 2 h, filtered with suction, washed with water (50 mL×3) for 3 times, and dried under vacuum at 50 °C for 18 h to obtain 17.5 g of white powder with a yield of 84.3%.

Ascorbyl Palmitate Powder Ecological Information

The production and also use Ascorbyl Palmitate Powder as an antioxidant as well as chemical preservative might result in its release into the setting via different waste streams. If released right into air, an estimated vapor pressure of 2.09X10-15 mm Hg at 25 ° C suggests that ascorbyl palmitate will just exist in the particle stage in the environment. The particulate phase ascorbyl palmitate will be eliminated from the environment by wet or completely dry deposition. Ascorbyl palmitate does not consist of a chromophore that soaks up at wavelengths > 290 nm and also is for that reason not anticipated to be impacted by direct sunshine photolysis. If released right into dirt, ascorbyl palmitate is anticipated to be moderately mobile based on an estimated Koc of 450. According to the approximated Henry’, volatilization from damp soil surface areas is not expected to be a considerable destiny process. The s-law constant is 1.4X10-7 atm-cu m/mole. No biodegradation information. If released to the approximated Koc, Ascorbyl Palmitate Powder is anticipated to adsorb into put on hold solids and sediments. Volatilization from water is not anticipated to be an essential fate procedure externally based upon estimated Henry’s law constants for this substance. The estimated BCF is 180, indicating a high possibility for bioconcentration in water organisms, supplied that the substance is not metabolized by organisms. The estimated base-catalyzed second hydrolysis rate constant is 2.85X10-2 L/mole-sec, corresponding to half-lives of 7.7 years and 280 days at pH 7 and 8, specifically. Occupational direct exposure to ascorbyl palmitate may result from inhalation as well as facial exposure to the substance in work environments where ascorbyl palmitate is generated or made use of. Usage data recommend that the general population might be subjected to ascorbyl palmitate via food intake as well as making use of medicinal products and also antioxidants consisting of Ascorbyl Palmitate Powder.
