Fats and oils (Plant Oils)

The video tutorial explains the extraction and structure of plant oils. Plant oils are derived from various parts of plants and can be extracted using mechanical extraction, distillation, or steam distillation. Mechanical extraction, also known as cold pressing, is used for oils like olive and coconut oil. Distillation is used for oils that are harder to extract, while steam distillation is used for floral oils. The structure of plant oils includes a hydrophilic glycerol head and hydrophobic fatty acid tails, which can be saturated or unsaturated. Saturated oils are solid at room temperature, while unsaturated oils are liquid. The video also covers the hydrogenation process and how to test oils with bromine water.

Explain the significance of hydrogenation in the context of plant oils.

How can one differentiate between saturated and unsaturated oils using bromine water?
