Microwave Cooking Principle and its Benefits

What are the benefits of Microwave Cooking 

How does the microwave work?

  • Microwaves are produced inside the oven by an electron tube called a magnetron
  • The microwaves are reflected within the metal interior of the oven where they are absorbed by food
  • Microwaves cause water molecules in the food to vibrate, producing heat that cooks the food
  • That’s why foods that are high in water content, like fresh vegetables, can be cooked more quickly than other foods
  • Although heat is produced directly in the food, microwave ovens do not cook food from the “inside out
  • When thick foods are cooked, the outer layers are heated and cooked primarily by microwaves
  • Food cooked due to the conduction of heat from the hot outer layers

 

When should I stop using my microwave?

  • Loud noises or alarm sounds are created at the end of the cooking cycle
  • Check for  sparks or smoke is there or not  then  you should stop using your microwave

 

Does Microwave radiate food?

  • The microwave energy is changed to heat as it is absorbed by food and does not make food “radioactive” or “contaminated

 

Utensil for Microwave Cooking

Best Utensils for Cooking

  • Glass and glass ceramic cookware is microwave safe as long as it doesn’t have gold or silver rims.
  • There are several types of utensils that are safe for use in the microwave, including:
    1. Glassware: Pyrex and other types of glass containers are safe to use in the microwave as long as they are labeled microwave-safe.

    2. Ceramic dishes: Ceramic dishes are also safe to use in the microwave as long as they are labeled microwave-safe.

    3. Plastic containers: Plastic containers labeled as microwave-safe can be used in the microwave, but it’s important to avoid containers that are not labeled as they may melt.

    4. Paper plates and bowls: Paper plates and bowls are safe to use in the microwave as long as they are labeled microwave-safe.

    5. Microwave-safe silicone utensils: Silicone utensils like spatulas, tongs, and steaming baskets are safe for use in the microwave.

  • It’s important to follow the manufacturer’s instructions for each type of utensil when using them in the microwave to ensure that they are used safely and correctly.

 

Avoid Metal and Plastic  for Microwave

  • Metal cookware should not be used in a microwave
  • Metal will not allow microwaves to penetrate and properly cook the food
  • When convection cooking in a microwave convection oven, metal and foil can be safely used
  • Microwaving plastic can release harmful chemicals like BPA and phthalates into your foods and drinks. Hence you should avoid microwaving plastic unless it’s labeled for this specific use

 

Different ways of Microwave Cooking

  5. Grilling: Microwaves can also be used to grill food. This is a great option for

 

Electrical Parts of Microwave

  • The cavity magnetron is the main component of a microwave
  • The magnetron is an oscillator where electrons are emitted from a hot cathode and whirl past resonant cavities which are part of the anode at speeds that generate microwave energy
  • The following are parts of microwave
    • Magnetron
    • High Voltage Transformer
    • Waveguide
    • Cooling Fan
    • Cooking Cavity
    • Turntable
    • Power Cord
    • Control panel
