a)Food preservation is the process of treating and handling food to stop or slow down Food spoilage , loss of quality, edibility or nutritional value and thus allow for longer food storage
Methods of food preservation of food
Stored in sugar solution
preserve from oxygen
By treating with nitrogen gas
Refrigeration of food
By pasturation method
b)1. Canning. There are two ways to can your food. The first is a water bath method, which is used for acidic fruits, jams, jellies, syrups, and pickling. Water bath canning is immersing canning jars with food in a bath of boiling water. This is a great way to get your feet wet with canning.
2. Dehydrating. Dehydrated food takes very little storage space. It’s lightweight enough to take with you on the go. To prolong its shelf life, it should be stored in a cool, dark, dry area. We dehydrate our herbs the old fashioned way, by hanging them in a warm dark area, but we use an electric dehydrator for our fruits and vegetables. You can dehydrate meat as well.
3. Cold storage or root cellar. This simply requires a cool, damp, and dark area for root crops, such as potatoes, carrots, beets, parsnips, cabbage, and apples. Winter squash and pumpkins prefer it a bit warmer and drier
4. Freezing. Freezing food allows it to keep
for many months and sometimes years if packaged properly. We use a deepfreezer for our beef, chicken, and some fruits and vegetables. Many
foods can be frozen that people don't typically think of. You can freezebutter, milk, cheese, and even eggs. Yep, you read that right. In the
summer when the hens are laying like crazy, you can put some of the eggsinto the freezer to use later.
5. Salt Curing. Before refrigeration and theinvention of the Mason jar in 1858, salt was used to cure meat. Salt draws the moisture out of the food. This is excellent for pork and fish, but can be done with beef as well. You'll need quite a bit of salt, some glass jars, and/or crocks. Learn how to salt water brine your pickles here
6. Immersion in Alcohol. Many foods can be immersed in alcohol to preserve them. Herbs and fruits are immersed in alcohol to create extracts. We make our own mint, vanilla, and lemon extracts this way. Your summer fruit can also be preserved in alcohol for summer baking.
