Methods of preparing oil:

Heat Process:

In this process oil extraction involves supplying a lot of heat about(230 c). In this seed is crushed, the pulp is heated under pressure. Due to this(poly cyclic aromatic hydrocarbons) are formed which strips off nutritional value. In this solvent hexane is added which is hazards to health.

Mechanical Process:

This method is called as expeller pressing where no heat is added but heat can be produces which alter the natural chemical compostion of the oil.oil.

Disadvantages of above methods:

• 1. In Thermal process or chemical treatment the nutrients tend to get destroyed by heat.
• 2. Processed oil changes the chemical make up & fats are no longer good for health.
• 3. For colour oil is bleached & Oil is over heated.
• 4. Chemically processed to increase the shelf life.

Wood Pressed:

Wood press or cold pressed oil is the natural & traditional method. A long cylindrical contraption called a Ghani was used. The oilseeds were placed inside and ground with a wooden pestle, which rotates at very minimal low temperature and extract oil. In this method for cold pressing the oil out of a seed because it doesn’t involve the generation or addition of heat.

Advantages:

• 1. Retain anti-oxidants which are otherwise destroyed by heat. It prevents the growth, tumors.
• 2. Rich in Vitamins, proteins, minerals & low in coastal. Vitamin E has anti-inflammatory healing properties.
• 3. A good source of oleic acid, which strengthens our immune system.
• 4. Prevents cancer & heart diseases, preventing hair fall.
