In recent times cold-pressed oils have become all the rage. The willingness to try and incorporate these traditional health foods in cooking is definitely making it popular among the health conscious.
Increasing rates of obesity, its associated diseases and awareness of how oil is extracted are few reasons why cold pressed oils are again finding place in our kitchen pantries.
With our markets offering a plethora of options in cooking oils (like gingelly, rice bran, canola, olive oil and so on), it is important to make informed choices. A surefire way to do this right, would be to go the local, non-blended and chemical free route. And if this seems liked a lot of work- ask your grandmother! What they have been traditionally consuming before all the modernisation is the ideal choice.
Extraction by industrial methods, involves various processes like bleaching, steaming, distillation and hydrogenation - the seeds are exposed to extremely high temperatures to get clear bland oil and chemicals like phosphoric acid, calcium hypo chlorite are added to increase the shelf life of the product which in turn affects not only the flavor and aroma but also strips the oil of all its nutritive values. The more refined an oil is the less nourishing it will be for our bodies.
Before said refined oils we were traditionally using cold pressed oils- in our local terms, “Chekku ennai/Ghani tel”. No heat or minimal heat was used for crushing/pressing the seeds and the process of production was simple without the addition of any solvent. The end product, thereby was qualitative with nutrients intact - making it ideal for cooking
