The Extraction Of Plant Oils

The video tutorial covers the origins, extraction methods, and structure of plant oils. It explains mechanical extraction, distillation, and steam distillation processes, highlighting examples like olive and coconut oils. The structure of plant oils is detailed, focusing on the glycerol head and fatty acid tails, which can be saturated or unsaturated. The video also discusses the properties of saturated and unsaturated oils, including their physical states and reactions with bromine water. Finally, it summarizes the key points about plant oil extraction and structure.

Which method is used to extract oils from olives?

• Steam distillation

• Mechanical extraction

• Chemical extraction

• Solvent extraction

What is the main characteristic of the glycerol head in plant oils?

• It is made of fatty acids

• It contains double bonds

• It is hydrophilic

• It is hydrophobic

What type of bonds are present in saturated fatty acid tails?

• Carbon-oxygen bonds

• Carbon-carbon single bonds

• Carbon-carbon double bonds

• Carbon-hydrogen bonds

What process is used to harden unsaturated oils?

• Emulsification

• Fermentation

• Hydrogenation

• Distillation

How can you differentiate between saturated and unsaturated oils in the lab?

• By measuring boiling point

• By checking solubility in water

• By testing with bromine water

• By using litmus paper
