What is Chekku Oil?
In the earlier days oil was prepared in traditional method using chekku. Bullocks were used to move around the marachekku (wooden pestle) and oil seeds in the chekku were crushed without generating any heat.
In the modern days now, the same system is replicated by replacing Bullocks with a Motor and Gearbox. The wooden pestle revolves at a speed of 14 rotations per minute. This is to ensure that oil is not heated and no nutrients is lost.
WHAT IS WOOD COLD PRESSED OIL?
Traditional chekku consist of a fixed stone bottom and the pestle is made up of a wood called “vagai”. In traditional wood chekku, the seeds are crushed with a wooden pestle. There are other types of chekku where the bottom and the pillar is made of steel.
The advantages of wood chekku over steel chekku is that the oil does not heated. Hence the vitamins and minerals are retained.
