1.1.1.1 there are two type of emulsion. oil droplets in water and water droplets in a liquid.
2 saturated fat
2.1 unsaturated fat

3 Vegetable oils are natural oils find in nuts, seed and some fruit.
4 the oil get extracted by pressing and squishing the oils out.
5 some oils are difficult to be extracted by pressing and squishing, they get dissolve in a solvent. when the oil dissolved the solvent removed and water will remove too to leave the pure vegetable oil.
6 vegetable oils in cooking.
6.1 vegetable oils have higher boiling point than water. this mean that food cook at higher temperature in vegetable oils than in water.
6.1.1 Also food cooked in vegetable oil cook faster and have different smell and flavors from cooked in water .
