Answer:
PRESERVATION OF FOOD
Explanation:
*DONOT WASTE FOOD
Answer:
1.Minimal Processing – Temperature Storage
Cool storage and room temperature storage are the easiest home food preservation options. This includes cool, dry storage, such as an unheated pantry or porch, and root cellaring, i.e., cool, damp storage.
2.Drying/Dehydrating
Food drying is one of the oldest home food preservation methods. Food can be dried using:Commercial dehydrators, such as the Excalibur or American a)Harvest Dehydrator
b)Solar dehydrators
c)Sun Ovens
d)Baking sheets in the oven
e)Air drying/hang drying
Dried foods are great when storage space is tight, but not all foods dehydrate well. Store dehydrated foods in a cool, dry location in an airtight container for longest shelf life.
3.Freezing
Freezing foods typically produces flavors and textures most similar to fresh, and requires little specialized equipment. Most vegetables require blanching or cooking before freezing to stop enzyme action and ensure best quality.
Preserving foods in salt and sugar was more common before modern canning, freezing and dehydrating were available. Salt and sugar draw liquid out of the food. This interferes with microbe growth. Bacteria and molds need water to grow, just like us.
Because they dramatically change flavor and texture, salt and sugar preserving are useful for those with adventurous palates.
