Typically, dehydration and irradiation. The causes of most food spoilage is the growth of bacteria in the moist environment of the food. Irradiation can kill all the bacteria, so as long as the package is sealed, no bacteria can grow there. And dehydration removes most of the water from the food so that it takes up less space and weight, and stays edible for longer times.
Depending on the type of the food many methods of preservation exist: adding sugar, salting, irradiation with gammas, freezing, lyophilisation, pasteurization etc.
Cobalt-60 and Cesium-137 are two radioactive isotopes commonly used to irradiate food for preservation purposes. They help eliminate harmful bacteria and pests, extending the shelf life of food products.
- Isotopes are used as sources of radiation in medicine, sterilization, nondestructive control, etc.- Isotopes can be used as tracers- Isotopes can be used as energy source- Isotopes are used for radioactive dating- Isotopes are used in chemical analysis- Isotopes are used in many instruments- Isotopes are used as source of nuclear energy in bombs and nuclear reactorsetc.
Yes, radioactive isotopes are largely used for the treatment of cancer.
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
preservatives are used in foods to keep the food from spoiling in a short period of time
Mainly dried foods are used; they minimize the weight of food at take-off and water can be recycled.
Preservatives are used to keep food from spoiling. The ubiquitous monosodium glutamate is the most famous of these and is found in virtually everything.
Depending on the type of the food many methods of preservation exist: adding sugar, salting, irradiation with gammas, freezing, lyophilisation, pasteurization etc.
First in First Out, also abreviated as FIFO is a process for rotating stock. The first products in, meaning the oldest, are the first ones to be used. This method is used primaraly in the food industry to keep food from spoiling before it is used.
They are used primarily to preserve food. In other words, to slow down the process of food spoiling, becoming "flat," etc.
In the past people used to pickle or cure their foods to keep the food from spoiling. And over the many years the refrigerator and freezer have made these methods less of a necessity than they once were.
in ancient time the people use ice and snow to preserve the food. Then they think about a machine to cool the food . this leads to the invention of refrigerator.
Cobalt-60 and Cesium-137 are two radioactive isotopes commonly used to irradiate food for preservation purposes. They help eliminate harmful bacteria and pests, extending the shelf life of food products.
Food can be preserved by putting into sealed cans. Or frozen, or kept cool in a refrigerator. Vacuum packing, freeze drying, salting, air or oven drying, pickling in vinegar, can also be used.

~Ceppwo The purpose of plastic wrap and aluminum foil is for food, it helps the food to stay good, without the plastic wrap and aluminum foil, it would be harder for us to keep it good, and with out it, the food would mold faster . . . so there's your answer:)
