Article Details :
Oil, which is extracted from fleshy palm fruit, is known as palm oil. It is semi solid in room temperature and offers numerous health benefits.
Characteristics
- This oil can be used as crude oil and its refined form can also be used
- In its crude form, it is orange in colour whereas refined palm oil is light yellow in colour
- Unrefined palm oil is termed as red palm oil
- Palm oil has a savory and earthy taste
- It is considered as the highest yielding oil crop
- It is extensively used by various food industries to prepare various food products and its adaptability and versatility to different food applications is considered as the result of its chemical composition
- It is widely used for preparing margarines, cooking oils and confectionary products
Preparation of palm oil
- The palm fruit should be washed properly for removing all dirt and impurities
- Then the fruits are subjected to extraction process
- The oil which is extracted by crushing the kernel of the palm fruit is known as palm kernel oil. Palm kernel is the nut that situated in the center of each fruit
- Whereas the oil which is obtained by squeezing the fleshy fruit is known as crude palm oil
Nutritional profile
- It contains significant amount of saturated fat as well as unsaturated fat but it does not contain any cholesterol
- It provides adequate amount of calorie on its oxidation
- It contains both monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) but it contains comparatively higher amount of MUFA than PUFA
- It has estimated that palm oil contains about 50% of saturated fatty acid, 40% of monounsaturated fatty acid and 10% of polyunsaturated fatty acid
- Its unsaturated fatty acid contents show numerous nutraceutical activities
- It also contains fat soluble vitamins and significantly rich in Vitamin E
Types
- There are two types of palm oil produced, which include, palm kernel oil and crude palm oil
- Both of the oils have potential health benefits
Health benefits
Antioxidant activity
- It exerts potent antioxidant activity that helps to reduce the risk of developing chronic diseases as it is related with inhibiting oxidative stress
- It helps to decrease the concentration of free radicals and ROS in body that help to protect the body from oxidative damages
- It also prevents lipid peroxidation
- It helps to prevent cellular damages as well thus improves their functionality
Role on nervous system
- Palm oil is significantly rich in Vitamin E, which plays imperative role in improving brain health
- It also helps to enhance brain functionality
- It plays significant role in protecting the brain tissues from free radical induced oxidative damages thus helps to decrease the susceptibility of developing neurological disorders
- It is also associated with halting the progression of brain lesions
- It has seen that its consumption is extremely beneficial for improving the symptoms of dementia
- It helps to improve cognition as well
Role on Vitamin absorption
- It plays imperative role in enhancing Vitamin A absorption
- It is packed with beta-carotene that is converted into vitamin A later in body thus its consumption is very effective for improving Vitamin A status in body
- As it is related with improving Vitamin A status thus its consumption is considered as extremely helpful for promoting vision
- It has seen that consumption of red palm oil during gestational period significantly improves vitamin A level in mother as well as in baby
- Individuals who suffer from Vitamin A deficiency should include palm oil in their diet for preventing respective deficiency disorders
Role on cardiac health
- It helps to promote cardiac health as well as cardiac functionality
- It has seen that cholesterol in excess amount can build up within artery thus makes the artery harder and narrower, which ultimately force the heart to work hard for pumping out blood throughout the body that creates additional burden to heart and gradually hinders cardiac function. As it is related with decreasing cholesterol level thus helps to slow down the progression of cardiac disorders
- It also helps to protect the heart from oxidative damages thus decreases the prevalence of cardio vascular diseases
Role on regulating cholesterol level
- There is a controversy between palm oil and cholesterol level. Some studies have shown that palm oil Read more
