  2. Rancidity

  3. Oxidation

  4. Polymerization


Correct Option: A
Explanation:

Smoke point is the temperature at which an oil or fat begins to smoke and break down. This can cause the oil or fat to taste bitter and produce harmful compounds.

What is the best way to store cooking oils and fats?

  1. In a cool, dark place

  1. It will have a sour or bitter taste

  2. It will have a dark color

  3. It will have a strong odor

  4. All of the above

What are some common problems that can occur when using cooking oils and fats?

  1. Smoke point

  2. Rancidity

  3. Oxidation

  4. Polymerization


Correct Option:
Explanation:

Smoke point, rancidity, oxidation, and polymerization are all common problems that can occur when using cooking oils and fats. Smoke point is the temperature at which an oil or fat begins to smoke and break down, rancidity is a process that occurs when oils and fats are exposed to light and air, oxidation is a process that occurs when oils and fats are exposed to oxygen, and polymerization is a process that occurs when oils and fats are heated to high temperatures.

What is the best way to prevent smoke point?

  1. Use a lower temperature

  2. Use a larger pan
