What Are The Specifications Of Vitamin E?
There are 8 members of the vitamin E family, divided into 2 categories:
- 4 kinds of Tocopherol: α-Tocopherol, β-Tocopherol, γ-Tocopherol, δ-Tocopherol
- 4 kinds of Tocotrienols: α-Tocotrienols, β-Tocotrienols, γ-Tocotrienols, δ-Tocotrienols
Among them, the α-Tocopherol content is the highest, and the biological activity is the largest. The activity of β-Tocopherol, γ-Tocopherol, and δ-Tocopherol is 50%, 10%, and 2%of α-Tocopherol, respectively. The activity of α-Tocotrienols is about 30%of α-Tocopherol.
The specifications of vitamin E are usually represented by international units (IU). Each of the above eight types is divided into different IUs.
For example, Vitamin E (D-Alpha Tocopherol) (500IU/G 630 IU/G, etc.)
The specifications of the mixed specifications are as follows:
D-Mixed Tocopherols powder, which includes 4 kinds of mixture D-α-Tocopherol, D-β-Tocopherol, D-γ-Tocopherol, and D-δ-Tocopherol.
D-Mixed Tocotrienols powder, which includes 4 kinds of mixture D-α-Tocotrienol, D-β-Tocotrienol, D-γ-Tocotrienol, D-δ-Tocotrienol.

Vitamin E Still Has Many Derivatives.
The shelf life of α-Tocopherol is generally two years, and the color and color of the color will not change within two years. However, the α-Tocopherol acetate obtained after α-Tocopherol Phenolone will be more stable, and the shelf life can reach five years.
Because the phenolic hydroxyl group is protected after ester, no phenols are not easily oxidized. As a result, it is more convenient to stabilize the storage and transportation of Tocopherol products. Both acetate and alter are α-Tocopherol esters.
What Are The Classifications Of Vitamin E?
Vitamin E is also divided into food grade, feed, and medicine.
Vitamin E is also divided into powder and oil.
Vitamin-E Succinate Powder (Tocopherol Succinate-D)
Natural vitamin E Oil (95% Mixed Tocopherols), etc.
The production process of VE is also divided into natural and synthetic.
For example, DL-α-Tocopherol is synthetic, and D-α-Tocopherol is natural.
Only α-Tocopherol has both natural forms and synthetic forms. The other 3 kinds of Tocopherol β-, γ-and δ- have only natural forms, without synthesis.
The common specifications of Vitamin E are as below:
- VE RRR-A-TOCOPHERYL ACETATE POWER 700 IU
- D-Alpha Tocopherol Succinate (VIT E) 1210 IU/GM
- Vitamin e succinate ve1185
- Vitamin E (as dl-alpha tocopheryl acetate) VE 50%
- Natural vitamin E (95% Mixed Tocopherols) Oil)
D-Alpha-Tocopherol is the most common and common specification. It is the main component of vitamin E and the most effective ingredient.
D-Alpha-Tocopherol Acetate is the ester of D-Alpha-Tocopherol, which is commonly used for food additives.
D-Alpha-Tocopherol Succinate is the acidic anhydride of D-Alpha-Tocopherol, commonly used for drugs and health products.
D-Alpha-Tocopherol Oil is an oily derivative of D-Alpha-Tocopherol. Mixed Tocopherol is a mixed type of vitamin E derivative.
In 2021, my country’s export volume of vitamin E was 91,300 tons, with an export value of 854 million US dollars. A total of about 25,000 tons in the world, the market share of natural vitamin E is about 20%, and the market share of synthetic vitamin E is about 80%.
