is the liquid fraction of palm oil.
Record of Safe Use:
oil has been safe and nutritious source of edible oil for healthy
humans for thousand of years.
oil and its liquid fraction, palmolein are consumed worldwide as
cooking oils and as constituents of margarines and shortenings;
these oils are also incorporated into fat blends used in the
manufacture of variety of food products as well as home food
Dietary Energy Source
other common edible fats and oils, palm oil is easily digested,
absorbed and utilized in normal metabolic processes. It plays a
useful role in meeting energy and essential fatty acid needs in
many regions of the world.
of Cholesterol and Trans Unsaturated Fatty Acids
oil like other vegetable oils is cholesterol free. Having a
naturally moderate level of saturation, it does not require any
hydrogenation for use as a fat component in foods and, as such,
does not contain trans fatty acids.
(unprocessed) and red or golden (specially refined) palm oils are
the richest natural sources of carotenoids. Beta-carotene, a major
carotene in crude palm oil is a potent antioxidant and precursor
of vitamin A.
oil and palm oil products are naturally occurring sources of the
anti-oxidant vitamin E constituents, tocopherols and tocotrienols.
These natural oxidants acts as scavengers of damaging oxygen free
radicals and are hypothesized to play a protective role in
cellular aging, athero-sclerosis and cancer.
Fatty Acid Composition
contains a mixture of polyunsaturated, mono-saturated and
saturated fatty acids. The relative concentrations are 44% oleic
acid, 10% linoleic acid, 40% palmitic acid and 5% stearic acid.
The concentrations of palmitic and oleic acids are reversed in
un-fractioned palm oil i.e. 44% and 40% respectively. The fatty
acid composition of palm oil is similar to that of adipose tissue
in most people in ordinary diet.
Linoleic Acid: An essential Fatty Acid
oil tri-glycerides linoleic acid predominantly in the 2-position,
which favours absorption and availability for use in the body.
oil is not Palm Kernel oil
oil from the fruit of the palm is physically and chemically
different from the either palm kernel oil which is derived from
the seed and from coconut oil both of which are highly saturated.
Human Feeding studies and epidemiological data have shown
that palm oil or palmolein do not

far as it affected cholesterol metabolism. A balance
linoleic acid (18:2) palmitic acid (16:0) may be required to

Substitution of palmitic acid (16:0) from palm oil or
palmolein for the lauric acid (12:0) and mystric
