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.
The 2 methods of food preservation is refrigeration and canning
Smoking, salting, canning/bottling, drying, freezing, pickling
Food preservation involves preventing bacteria growth using methods that include freezing. Canning, pickling, dry salting, fermenting, and drying are other methods of preservation used for food items.

Some methods of food preservation are acidic, like pickling foods and chemicals like benzoic acid are used to keep food fresh.
Methods of preserving food include smoking and drying. Canning is another common method of food preservation. Pickling is one of the oldest forms of food preservation.
For detailed instructions on canning and pickling and recipes refer to the National Center for Home Food Preservation (NCHFP) website, it is an excellent source for current research-based recommendations for most methods of home food preservation.
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.
Yes, bases can be used in pickling, though they are less common than acids. While traditional pickling primarily relies on acidic solutions, such as vinegar, some modern techniques utilize alkaline solutions to achieve specific textures or flavors. However, it's important to note that using bases can alter the preservation properties and is not typical in traditional pickling methods.
Asian preservation methods often include fermentation, pickling, and drying. Fermentation is used in products like kimchi and soy sauce, enhancing flavor and extending shelf life. Pickling involves soaking vegetables in vinegar or brine, commonly seen in dishes like Japanese tsukemono. Drying, whether through sun-drying or air-drying, helps concentrate flavors and preserve ingredients like fish and fruits, making them last longer.
