Therapeutic uses of Sesame oil

Sesame oil for body, skin and hair:

Sesame oil does wonders to your body, skin, and hair.

Regular WEEKLY practice of having full body oil bath relaxes and rejuvenates the entire body and your skin. Massaging the head and body with sesame oil removes the heat from our body, especially during hot summers. It helps to reduce the stress in the eyes, especially people who spend a lot of time staring the computers will greatly benefit from oil bath. Sesame oil is a wonder oil.

Traditionally in India, usually every Friday women have their oil bath and men have their oil bath on Saturdays.

Oil pulling:

In the morning, before breakfast on an empty stomach, pour one tablespoon (10ml) of Sesame Oil into your mouth. Swish and swirl the Sesame Oil gently, in a comfortable way, through the gums and teeth. Do it till the oil gets thinner and whiter (10-15 min). Then spit and rinse the oral cavity thoroughly with warm salt water. Do not swallow even a drop of oil as it contains toxins, which have been pulled out from the blood while swishing. The spitted oil can eventually clog up the sink. Clean the sink with soap immediately after spitting.

In addition to improving oral health, Oil Pulling normalizes nervous activity – disappearing pains, such as headache, etc. It benefits overall physical health.

Why did we start consuming Refined oils? And why we should stop now!

Naturally, oil seeds can be pressed to extract oil (Like pressing juice from a fruit). Sesame seeds, Coconut, Groundnut/Peanut, Olive, etc are a few from which oil can be extracted by just pressing, which is a natural process. This natural process in known as Cold Pressed and this method has been used for 1000s of years around the world. Origins of Cold Pressed oil can be traced backed to the Indus Valley Civilization. Charred sesame seeds and oil-pressing machines were found in the ruins of Harappa and were dated to be 5000 years old.

But, refined oils are manufactured by using chemical extractions process that includes high temperatures, high pressures, multiple chemical solvents, etc. This yields in a “oil” which is unhealthy but very consistent in terms of colour, smell and shelf life.

So, the questions is – Why did refined oils come into the market?  Why are oils extracted chemically when it can be extracted naturally?

  • Seeds such as rapeseed (canola), soybean, corn, sunflower, safflower, etc CANNOT yield oil through natural extraction techniques. To extract oil from these seeds, only chemical refining process works. Also, when manufacturers discovered chemical extraction techniques, they started using this even on oil seeds (groundnut, sesame, etc) from which oil can be extracted naturally using cold pressed method 

  • Cold pressed oil extraction can be done only in small batches (quantity). Whereas, refining and chemical extraction can be done in large scale by setting up big machinery

  • Refined oil extraction has higher oil yield. For example, in cold pressed method we need 2.5kg of groundnuts to make 1 litre of groundnut oil. The refined process will extract 1 litre of oil from 2.2 kg of groundnuts

  • As refined oil is neutralized for taste, colour and odour, very low quality oil seeds are used. (Cold pressed oil has to use only good quality oil seeds; otherwise, a consumer will indentify the lapse in quality)

  • This is the most shocking part. Palm oil constitutes nearly 45% of edible oil consumed in India. Palm oil is the most consumed oil. How? Nobody goes to the grocery store to buy Palm oil and there isn’t Palm oil in grocery store shelves, yet we consume so much palm oil. Cheap and neutral oils such as palm oil, cotton seed oil, etc. are mixed with other oils for profits. This is a widespread and accepted “Oil blending” practice in the oil industry. Google it, you will be shocked. Refined process allows this blending where consumers will not be able to find the difference. And FSSAI (Food Safety and Standards Authority of India) allows blending of oils as blending is a very common practice

  • Refined oil has longer shelf life as it is chemically treated. There is nothing to be spoilt in it as there is no organic life in it

 

Palm oil is the most consumed oil in India. This is because refined oils are blended with Palm oil.

 

With business objectives to make more money, oil manufacturers ventured into chemically extracted refined oils. Chemical extraction allowed them to extract oil at low cost and with huge marketing budgets, they have changed our consumption patterns. 

These days Refined oils are advertised as Vitamin +. Oil should be a natural product!  What is added to make it Vitamin +?

With access to information, it is time that we as consumers make the right choice when it comes to oils and our health.

Cold Pressed Oil Vs. Refined Oil. Why you should NOT use Refined oils.

`

Cold Pressed oil Vs.  Refined oil

How are oils made?  

 

COLD PRESSED OIL

Naturally, oil seeds can be pressed to extract oil (Like pressing juice from a fruit). Sesame seeds, Coconut, Groundnut/Peanut, Olive, etc are a few from which oil can be extracted by just pressing, which is a natural process. 

Steps

HAPRAPPA COLD PRESSED oil processing steps

Short description

1

Oil seeds are cleaned and dried to remove any moisture in it

Natural drying using sunlight

2

The seeds are then crushed using a slow grinding machine with a Pestle and Mortar. (Just like pressing juice from a fruit)

Natural squeezing

3

The oil extracted is then filtered to separate the oil from the seed pulp 

Natural gravity sedimentation

 

“Chekku”, “Ghani” & “Kolhu” oil are some colloquial words used in India to describe Cold Pressed Oil machines.  This is THE NATURAL METHOD OF EXTRACTING OIL. Since no heat is applied during the extraction (unlike refined oils) this natural method is known as COLD PRESSED.

In ancient times, a cow was used to grind oil seeds to make oil. These days we use a mechanical oil pressing machine as shown in the image. 

 

REFINED OIL

Other oils seeds such as rapeseed (canola), soybean, corn, sunflower, safflower, etc CANNOT yield oil through natural extraction techniques. These vegetable oils were non-existent until the early 1950s, when chemical treatment and processing (refining) techniques allowed them to be extracted. Because these oils are chemically extracted, they need to be refined. Our bodies weren’t meant to consume chemically extracted refined oil.

Steps

Refined oil processing steps

Short description

1

Oil seeds (groundnuts, sesame, coconut, sunflower seeds, etc) are crushed and then heated in a steam bath – 110 to 2000 Celsius

HIGH TEMPRATURE

2

The mixture of oil and seed pulp is then chemically processed with a hexane solvent to extract any residual oil from the pulp. (Hexane is produced by refining crude petroleum oil)

HEXANE SOLVENT

3

This resulting mixture is then put through a centrifuge and phosphate is used to separate the oil from the seed residues

PHOSPHATE

4

Water degumming: Here water is added. This reaction with water results in hydrated phosphatides, which can be separated by decantation or by centrifuges. 

HYDRATED POPHATIDES

5

Neutralization: The resulting product from the above steps contains fatty acids, phospholipids, pigments, waxes, etc. These impurities are removed by using caustic soda (sodium hydroxide) or soda ash (sodium carbonate). The refined oil is lighter in color, less viscous and easily prone to oxidation

CAUSTIC SODA/SODA ASH

6

Bleaching: This is done to remove off coloured materials. Bleaching agents are used in this process

BLEACHING AGENTS

7

Deodorization: Pressurized steam at very high temperatures (500F) is used to remove volatile compounds which cause off odours and taste in the final product.

HIGH TEMPRATURE

 

This process kills all the nutrition and alters the molecules in unfavourable ways – making it very unhealthy. This chemical process yields “oil” that is very unhealthy, but very consistent in terms of colour, smell, odour and shelf life.

When you take a natural food product and expose it to multiple chemical processes, how can it be natural and healthy?

Multiple studies have linked consumption of refined oils to many chronic diseases. Chemically extracted oils lead to inflammation within the body, elevated blood triglycerides and an impaired insulin response, etc. 

 

These days Refined oils are advertised as “Vitamin +”. Oil should be a natural product!  What is added to make it Vitamin + ?

 

Making oil is such a simple process. Then why do Refined oils exist?

  • Seeds such as rapeseed (canola), soybean, corn, sunflower, safflower, etc CANNOT yield oil through natural extraction techniques. To extract oil from these seeds, only chemical refining process works. Since 1950s, manufacturers also started using refining process for groundnut, sesame, coconut, etc. 

  • Refined oil extraction has higher oil yield. For example, in cold pressed method we need 2.5kg of groundnuts to make 1 litre of groundnut oil. The refined process will extract 1 litre of oil from 2.2 kg of groundnuts

  • Since refined oil is neutralized for taste, colour and odour, very low quality oil seeds are used. (Cold pressed oil has to use only good quality oil seeds; otherwise, a consumer will indentify the lapse in quality)

  • This is the most shocking part. Palm oil constitutes nearly 45% of edible oil consumed in India. Palm oil is the most consumed oil. How?
