Coconut Oil

Image

The kernel or meat of mature coconuts collected from the coconut palm are used to extract coconut oil. It has a higher percentage of saturated fat, which slows oxidation and makes it resistant to rancidity, lasting up to two years without rotting. Certain fatty acids and derivatives of coconut oil have been shown to have negative impacts on the inactivation of microorganisms such as bacteria, yeast, fungi, and enveloped viruses. Mechanical extraction methods are commonly used to get coconut oil. Well-dried copra is pressed in a screw press or hydraulic press to extract oil by shattering the oil cells in the kernel in the dry extraction process. Filtration separates the oil and cake after extraction. According to a study, unrefined coconut oil is more stable than refined coconut oil since refined oil contains less tocopherol (Gordon and Rahman 1991). Cake can be used as a substrate for Aspergillus oryzae species to produce alpha amylase (Ramachandran et al. 2004). Oil extraction employing enzymes such as polygalacturonases, á-amylase, and proteases was found to be a more efficient process in terms of energy use, with an 8 percent yield (McGlone et al. 1986).

Coconut oil is an important cooking medium in many countries. Besides, the oil has varied industrial applications. It is used in the manufacture of toilet soaps, laundry soaps, surface active agents and detergents, hair tonics, cosmetics, etc. It is used throughout the country as a hair oil as it helps growth of the hair. As a massage oil it has a cooling effect on the body. Owing to these qualities coconut oil has a potential market. Since the price of coconut oil in the international market is very much lower than the domestic price, the quality and attractiveness of consumer packs are important factors to compete in the world market. While the demand for coconut oil for cooking purpose is elastic, its demand as hair oil is inelastic.

Coconut oil offers numerous health advantages, with its primary benefits revolving around its efficacy in maintaining the health of hair and skin.

  • Support Weight Loss by Burning Fat
    Unrefined, cold-pressed coconut oil is particularly advantageous for weight loss. It’s packed with short and medium-chain fatty acids that aid in shedding excess weight. Research has shown its effectiveness in reducing abdominal obesity among women. Compared to other edible oils, it’s easier to digest and promotes the well-being of the thyroid and endocrine system. 
  • Healthy skin A study conducted in 2018 on the impact of plant oils on the skin discovered that coconut oil is abundant in properties that are antibacterial, anti-aging, antioxidant, aid in wound healing, and anti-inflammatory. 
    a. Xerosis or dry skin
    Can be effectively treated with pure, cold-pressed, organic, non-GMO coconut oil. This oil serves as an excellent massage oil and a potent moisturizer suitable for all skin types, especially dry skin.
  • Reduce Seizure
    Recent studies indicate that coconut oil can enhance the cognitive functions in patients with Alzheimer’s disease. The medium-chain triglycerides (MCTs) present in coconut oil are a significant source of ketones, which are linked to memory improvement.
  •  Improve your Immunity
    Coconut oil bolsters the immune system due to the presence of antimicrobial lipids, lauric acid, capric acid, and caprylic acid. These components possess antifungal, antibacterial, and antiviral qualities.
  • Dental care
    Calcium, a crucial element of our teeth, is absorbed more effectively by the body with the aid of coconut oil, leading to the development of robust teeth. This oil also plays a role in preventing tooth decay. Recent studies indicate that the practice of oil pulling with coconut oil can help decrease the formation of plaque and plaque-induced gingivitis.
