Oil soluble antioxidant
2018-1-5 16:15:07
Oil soluble antioxidant are mainly used in the antioxidation of oil soluble drugs. The commonly used oil soluble antioxidant, butylated hydroxyanisole (BHA), 2, 62 Di tert butyl hydroxytoluene (BHT), vitamin E, ascorbic acid and palmitate.
Vitamin E, also known as tocopherol, is a phenolic compound. It is one of the first vitamins to be found and is a natural tocopherol compound. General vitamin E includes four isomers of alpha, beta, gamma and delta. Its antioxidant activity is < < < < < Delta. The sixth hydroxyl group of its heterocyclic ring is an active group. It can release active hydrogen from its hydroxyl and capture free radicals, thereby blocking free radical chain reaction. In addition, the O2C bond can be broken through the tocopherol free radical oxygen complex naphthalene, and the free radical can be removed directly by combining with OH.
Therefore, the oil soluble antioxidant natural vitamin E is a strong and effective antioxidant. Generally, vitamin E and vitamin C are combined, vitamin E and tea polyphenols are combined, and citric acid synergist is added. It has good synergistic effect and can be applied to antioxidants of animal and vegetable oils and fat soluble drugs.
L-ascorbyl Palmitate is a new antioxidant, the small dosage, high safety, is a promising antioxidant. Its antioxidant mechanism is various. It can be used as an oxygen dispersant. It can be used as reducing agent, chelating agent of multi valent metal ions, synergist and synergist of other antioxidants in specific pharmaceutical preparations.
Ding Ji hydroxy anisole, also known as tert Ding Ji -4- hydroxy anisole, and Ding Ji anisole, called BHA, is a mixture of two components (3-BHA and 2-BHA). The molecular formula is C11H16O2, and the relative molecular mass is 180.25. The antioxidant effect of Ding Ji hydroxy anisole is achieved by releasing hydrogen atoms to block the automatic oxidation of oil.
Two butyl hydroxy toluene is white crystalline or crystalline powder. It is basically odorless, tasteless, melting point 69.5~71.5 C, boiling point at 265 degrees C, which is quite stable to heat. Contact metal ions, especially iron ions do not show color, the antioxidant effect is good. When heated, it volatilized with water vapor. Insoluble in water, glycerin and propylene glycol, but easy to dissolve in ethanol (25%) and oil. For example, it is easy to dissolve in the oil and plant oil, and can not be coloured with metal ions, and is susceptible to the influence of sunlight and heat.
A specific odor with a phenolics and a stimulant odor, usually a mixture of 3-BHA and 2-BHA. The melting point varies with the mixing ratio, for example, the BHA melting point of 3-BHA is 95%, and the melting point is 62.
The volatility of a mono - Phenolic type is slightly volatile in pig fat at 61 C. There is almost no hygroscopicity. The heat is quite stable, and the light color becomes deeper for a long time and is stable under the weak alkali condition.
Triphenyl phosphite (TPPi antioxidants, stabilizer) is mainly used in PVC, polyethylene, polypropylene, polystyrene, polyester, abs resin, epoxy resin, synthetic rubber antioxidant stabilizer, used in polyvinyl chloride (PVC) products as a chelating agent, when is given priority to with metal stabilizer, cooperate with this product can reduce the harm of metal chlorides, maintain product transparency, and inhibition of color change, is also a good chemical intermediates, with phosphorus-containing flame retardant and use, can play a role of flame retardant antioxidant, and with stable performance, light can be used for synthesis alkyd resin and polyester, main raw materials for resin, this product can also be preparing pesticide intermediates trimethyl phosphite.
The antioxidant effect of 3-BHA is 1.5 to 2 times stronger than that of 2-BHA, and both of them have synergistic effect. The dosage of 0.02% was 10 times stronger than the dosage of 0.01%, but the effect decreased by more than 0.02%.
Ding Ji hydroxyl anisole (butylatedhydroxylanisole, BHA) is relatively stable to heat, and it is not easy to be destroyed under weak alkaline conditions, so it is a good antioxidant. The antioxidative effect of BHA on animal fat is more effective than that of unsaturated vegetable oil. It is especially suitable for roasting products that use animal fat. BHA has the characteristics of discoloration with alkaline earth metal ions, so iron and copper containers should be avoided in use. The combination of citric acid or tartaric acid, which has chelating action, not only plays an synergistic effect, but also prevents the color action caused by metal ions. BHA has a certain volatility and can be distilled by water vapor, so it is easy to lose in high temperature products, especially in the frying products. BHA can also be used as a packaging material for food.
Vitamin E (Vitamin E) is a fat soluble vitamin, and its hydrolysate is tocopherol. It is one of the most important antioxidants. Soluble in organic solvents such as fat and ethanol, it is insoluble in water, stable in heat and acid, unstable in alkali, sensitive to oxygen and insensitive to heat, but vitamin E activity is reduced significantly during frying.
Vitamin E is a fat soluble vitamin in 8 forms and is an important antioxidant.
Vitamin E includes tocopherols and three ene tocopherol two kinds of 8 compounds, namely, alpha, beta, gamma, delta tocopherol and alpha, beta, gamma, delta three ene tocopherol, alpha tocopherol is the most widely distributed, the most abundant and the most active form of vitamin E in nature.
Vitamin E has anti-oxidation effect is very stable to heat, acid, alkaline instability, if the lead salts, salt or oil rancidity conditions, will accelerate the oxidation and destruction.
Tocopherol has four main derivatives, which are divided into four kinds, namely, alpha, beta, gamma and delta according to the methyl position. The activity of three alkenols related to tocopherol in the substituent group is certain, but the activity of tocopherol can be significantly reduced.
Ascorbyl palmitate was palmitic acid and L- ascorbic acid esterification and other natural ingredients, its molecular formula is C22H38O7, is a highly efficient oxygen scavenger and synergistic agent, WHO (WHO) assessment committee on food additives used as food additive safety with nutrition, non-toxic, high efficiency, and is the only available for infant food this product is used for food antioxidant, can play antioxidant, food (fat) color, nutrition and other effects.
