  4. Pickling


Correct Option: C
Explanation:

Curing is a method of food preservation that involves adding salt or sugar to food to inhibit the growth of microorganisms and extend the shelf life of the food. Curing can be done with dry ingredients, such as salt and sugar, or with a brine solution.

Which method of food preservation involves submerging food in a vinegar solution?

  1. Canning

  2. Freezing

  3. Pickling

  4. Dehydration


Correct Option: C
Explanation:

Pickling is a method of food preservation that involves submerging food in a vinegar solution to inhibit the growth of microorganisms and extend the shelf life of the food. Pickling can be done with a variety of foods, including vegetables, fruits, and meats.

Which method of food preservation involves storing food at a very low temperature, typically below 0°F (-18°C)?

  1. Canning

  2. Freezing

  3. Dehydration

  4. Pickling


Correct Option: B
Explanation:

Freezing is a method of food preservation that involves storing food at a very low temperature, typically below 0°F (-18°C), to inhibit the growth of microorganisms and extend the shelf life of the food. Freezing can be done with a variety of foods, including fruits, vegetables, meats, and dairy products.

Which method of food preservation involves heating food to a high temperature and then sealing it in airtight containers?

  1. Canning

  2. Freezing

  3. Dehydration

  4. Pickling


Correct Option: A
Explanation:

Canning is a method of food preservation that involves heating food to a high temperature and then sealing it in airtight containers to prevent the growth of microorganisms and extend the shelf life of the food. Canning can be done with a variety of foods, including fruits, vegetables, meats, and fish.

Which method of food preservation involves adding lactic acid bacteria to food to produce lactic acid, which inhibits the growth of harmful bacteria?

  1. Canning

  2. Freezing

  3. Dehydration

  4. Fermentation


Correct Option: D
Explanation:

Fermentation is a method of food preservation that involves adding lactic acid bacteria to food to produce lactic acid, which inhibits the growth of harmful bacteria and extends the shelf life of the food. Fermentation can be done with a variety of foods, including vegetables, fruits, and dairy products.

Which method of food preservation involves adding sulfur dioxide to food to inhibit the growth of microorganisms?

  1. Canning

  2. Freezing

  3. Sulfuring

  4. Pickling


Correct Option: C
Explanation:

Sulfuring is a method of food preservation that involves adding sulfur dioxide to food to inhibit the growth of microorganisms and extend the shelf life of the food. Sulfuring is commonly used to preserve dried fruits, such as raisins and apricots.

Which method of food preservation involves exposing food to ionizing radiation to kill microorganisms?

  1. Canning

  2. Freezing

  3. Irradiation

  4. Pickling


Correct Option: C
Explanation:

Irradiation is a method of food preservation that involves exposing food to ionizing radiation to kill microorganisms and extend the shelf life of the food. Irradiation is commonly used to preserve fruits, vegetables, and meats.

Which method of food preservation involves adding preservatives to food to inhibit the growth of microorganisms?

  1. Canning

  2. Freezing

  3. Dehydration

  4. Preservation


Correct Option: D
Explanation:

Preservation is a method of food preservation that involves adding preservatives to food to inhibit the growth of microorganisms and extend the shelf life of the food. Preservatives can be natural or synthetic and are commonly used in processed foods.

Which method of food preservation involves coating food with a protective layer to prevent the growth of microorganisms?

  1. Canning

  2. Freezing

  3. Coating

  4. Pickling


Correct Option: C
Explanation:

Coating is a method of food preservation that involves coating food with a protective layer, such as wax or oil, to prevent the growth of microorganisms and extend the shelf life of the food. Coating is commonly used to preserve fruits, vegetables, and meats.

Which method of food preservation involves storing food in a controlled atmosphere, such as a modified atmosphere packaging (MAP) or controlled atmosphere storage (CAS), to inhibit the growth of microorganisms?

  1. Canning

  2. Freezing

  3. Controlled Atmosphere Storage

  4. Pickling


Correct Option: C
Explanation:

Controlled Atmosphere Storage (CAS) is a method of food preservation that involves storing food in a controlled atmosphere, such as a modified atmosphere packaging (MAP) or controlled atmosphere storage (CAS), to inhibit the growth of microorganisms and extend the shelf life of the food. CAS is commonly used to preserve fruits, vegetables, and meats.
