- Oil can be extracted from plant materials by pressing them or by distillation.
- Vegetable oils are unsaturated. They are used to cook foods because they boil at a higher temperature then water
- they are important foods and fuels as they provide a lot of energy and nutrients.
- Vegetable oils are unsaturated. They are used to cook foods because they boil at a higher temperature then water
- Oils don't dissolve in water, they can be used to produce emulsions.
- Emulsions are thicker than oil or water and have many uses that depend on their special properties.
- they provide better texture, coating ability, and appearance
- Emulsifiers are used to stop water and oil separating.
- they work because different parts of the molecule are attracted to the different liquids.
