Oil from Seeds
Vegetable oils are made from seeds and fruits of many plants growing all over the world, from tiny sesame seeds to big, juicy coconuts. Oil is produced from cotton seeds, groundnuts, soya beans and sunflower seeds. Olive oil is used for cooking, salad dressing etc. Olives are shaken from the trees and gathered up, usually by hand. The olives are grounded to a thick paste which is spread onto special mats. Then the mats are layered up on the pressing machine which will gently squeeze them to produce olive oil
