cold pressed gingelly oil

The edible oil that we currently use for cooking is generally hot pressed oil. However, in the recent period, once people gained awareness about the importance and benefits of Cold Pressed oil, it became very popular.

The major difference lies in preparing the input material used to press the oil, rather than pressing techniques. The input we feed to the press the oil has the overall influence to a great extent on the properties of the oil. Of course, the way of pressing also impacts the benefits and properties of the oil.

  • Cold Pressed oil means the inputs (seeds) are pressed in low temperature. To put in a lighter note, the seeds are pressed raw without roasting.
  • Hot pressed oil means the seeds are roasted and pressed under very high temperature.

3 Differences of Hot Pressed Oil and Cold Pressed Oil

  1. Processing Technology
  2. Nutritional Value and Properties
  3. Market Value

Processing Technology

Cold Pressed Oil

  • No need for pre-preparation or preconditioning of the seeds/input materials.
  • Pressed directly under the room temperature.
  • Low temperature is preferred to press the oil and should be below 49 degree celsius.

All these collectively make the oil low in acidic value, which does not require refining the oil. Oil is just ready to use immediately after precipitation and filtration.

Hot Pressed Oil

  • Just opposite to the Cold Pressed oil.
  • The seeds are heated by roasting.
  • In order to retain the fragrance of the raw seeds (which might go away during roasting), some chemicals are added. Chemicals are also added to increase the yield.
  • After treating with chemicals, the seeds are pressed under high temperature and the color of the oil extracted remains dark.
  • Besides, the acidic value of the oil is very high due to the use of chemicals, which almost resembles crude oil.
  • The oil is refined by the removal of dust particles, stone particles, reducing the acidic value and so on.

Nutritional Value

Cold Pressed Oil

So, it is very apparent that Cold Pressed oil is more nutritious than hot pressed oil. Since it is not processed under high temperature and retains most of the natural active ingredients, it is nutritious. Besides, it also retains the original taste and aroma. To lead a healthy life, Cold Pressed oil is highly recommended.

Hot Pressed Oil

At every stage of processing, hot pressed oil is likely to lose the nutritional value. Especially, extraction under high temperature, chemical treatment as well as the refining process reduces the nutritious value of the oil. However, in some seeds, the hot pressed oils retain the fragrance for a longer time and yield more.

Market Value

Cold Pressed Oil

Cold press oil is very light and the aroma is fresh. However, it may not have the fragrance while used in cooking equivalent to the hot pressed oil. It carries the mild to moderate unripe flavor which is not preferred by many. Due to yield, the cost of Cold Pressed oil is high.

Hot Pressed Oil

Usage of hot pressed oil is wide spread. The flavor and ability to withstand the aroma for a longer period makes it comfortable to cook. However, the refinement of hot pressed oil makes it inferior in terms of healthiness.
