Description
Natural Vitamin E
(Tocopherol) is derived from soybean oil, as nature’s fat-soluble
antioxidant constitutes: Alpha-tocopherol,
Beta-tocopherol, Gamma-tocopherol, Delta-tocopherol.
Beta-tocopherol exists in concentrations too low to have any
practical significance, free of solvent residue and metal ion.
Gamma and Delta-tocopherols are known primarily for their
antioxidant properties. Being used as antioxidant, their
physiological activities is: Delta > Beta > Gamma > Alpha.
Nowadays, Natural Vitamin E is divided into Mixed Tocopherol (Low
alpha-tocopherol) and Tocopherol (High
alpha-tocopherol).
Molecular
formula:
Alpha-tocopherol:
R1=R2=CH3,
Beta-tocopherol: R1=H,
R2=CH3
Gamma-tocopherol: R1=CH3,
R2=H
Delta-tocopherol:
R1=R2=H,
Characteristics:
• Brownish or light yellow,
transparent oil-like liquid with mild and special
odor.
• Density
0.****0.**5 and high boiling point **0 (*3.*3
Pa).
• Soluble in
ethanol, acetones, diethyl ether, chloroform and vegetable oils
& fats, Insoluble in water.
• No calorie,
not involved in metabolism in human body .
Use:
In food/pharmacy
industry
• As a natural
antioxidant inside cells, supplies oxygen to blood, which is
carried to the heart and other organs; thus alleviating fatigue;
aids in bringing nourishment to cells.
• As an
antioxidant and nutrition fortifier which is different to the
synthetic on components, structure, physical characteristics and
activity. It has rich nutrition and high security, and is prone to
be absorbed by human body.
In feed and poultry feed
industry
• As dietary
supplements and in food technology as
antioxidant.
• Acts as an
antioxidant controlling redox reactions in a variety of tissues and
organs.
• Also provide
protection against pulmonary oxygen poisoning.
In cosmetics
industry
• Improves
microcirculation of the skin.
• Protects
against U.V irradiations.
• Maintains natural
moisture of skin
The
difference between natural and synthetic Vitamin E is mainly on
Physiological activity and toxicity- C Proven by test with mice,
U.S.FDA generally considers natural Vitamin E as safe and ranked
into GRAS, while synthetic Vitamin E contains LD*0 of 5g/kg. When
used as nutrition fortifier, the physiological activity of natural
alpha Vitamin E is 1.*9 times of that of synthetic
product.
