Advantages
Can be used to destroy or inactivate organisms that cause spoilage and decomposition
Foods that are sterilized by irradiation can be stored without refrigeration for years
Offers an alternative to chemicals for use with grains, potatoes, citrus and tropical fruits, seasonings, and spices
Irradiation kills any bacteria present in the food which prevents it from going off. Irradiation can be performed on food that is already sealed in packaging meaning that it will then be sterile which can give it a very long shelf-life. Irradiation can kill bacteria without heating the food when doing so would destroy or change it e.g. fruit.
Depending on the type of the food many methods of preservation exist: adding sugar, salting, irradiation with gammas, freezing, lyophilisation, pasteurization etc.
irradiation

Some modern methods for food preservation include refrigeration, freezing, canning, vacuum packaging, irradiation, and high-pressure processing. These methods help extend the shelf life of food products by slowing down microbial growth, enzyme activity, and oxidation.

Taste is amazing
There are numerous methods of food preservation, mainly depending on the purpose. Traditional food preservation techniques include curing, drying, refrigeration, freezing, smoking, pickling, canning, bottling and jellying. Industrial techniques include pasteurization, vacuum packing, Irradiation, Artificial food preservatives and bio-preservation.
Pro: Salting food is a cheap and effective preservation technique.Con: The food may taste too salty if it is not properly prepared.
Drying is a method of food preservation that works by removing water from the food
