Some minor components in CPO bring
undesirable effects to oil
E.g: phospholipids (surface active agent:
disperse impurities in oil)
Remove by refining to produce good quality
of refined oil

MINOR CONSTITUENTS OF PALM OIL BENEFICIAL EFFECT
CAROTENOIDS
• human body uses carotenoids as Vitamin A.
• enhance immune function by a variety of mechanisms & can improve cardiovascular health.
• acting as biological antioxidants, protecting cells & tissues from the damaging effect of free radicals.
TOCOPHEROLS &TOCOTRIENOLS
• Natural vitamin E exists in eight different forms or isomers,four tocopherols & four tocotrienols.
• Tocotrienols in Vitamin E have been found to have antioxidant & anticancer activities.
• preventing skin aging, preventing fat oxidation & reducing blood pressure.
• palm tocotrienols have the ability to reverse blockage of the carotid artery & platelet aggregation.
• Tocotrienol-rich fraction of palm oil is capable of protecting brain against oxidative damage & thereby from the ensuing adverse alterations that accompany aging.
MINOR CONSTITUENTS OF PALM OIL
BENEFICIAL EFFECT
Fatty acid • focus of attention in determining its nutritional adequacy in relation to coronary heart disease (CHD) risk factors
Monoglycerides • used as emulsifiers in foods
Mineral oil • medicinal uses
• use in the kitchen is to saturate the cutting board and other wood items to make them water resistant
Types of fatty acid
Saturated - 50%
unsaturated – 50%
Saturated :
44.0% Palmitic acid
5.0% stearic acid
