Pickling
Pickling, or matt wise, is the process of preserving food by anaerobic fermentation in brine (a solution of salt in water), to produce lactic acid, or marinating and storing it in an acid solution, usually vinegar (acetic acid). The resulting food is called a pickle.
The distinguishing feature is a pH less than 4.6, which is sufficient to kill most necrobacteria[1]. Pickling can preserve perishable foods for months. Antimicrobial herbs and spices, such as mustard, garlic, cinnamon or cloves, are often added.[2]
If the food contains sufficient moisture, a pickling brine may be produced simply by adding dry salt. For example, sauerkraut and Korean kimchi, are produced by salting the vegetables to draw out excess water. Natural fermentation at room temperature, by lactic acid bacteria, produces the required acidity. Other pickles are made by placing vegetable in vinegar. Unlike the canning process, pickling which includes fermentation requires that the food not be completely sterile before it is sealed. The acidity or salinity of the solution, the temperature of fermentation, and the exclusion of oxygen determine which microorganisms dominate, and determine the flavor of the end product.

When both salt concentration and temperature are low, Leuconostoc mesenteroides dominates, producing a mix of acids, alcohol, and aroma compounds. At higher temperatures Lactobacillus plantarum dominates, which produces primarily lactic acid. Many pickles start with Leuconostoc, and change to Lactobacillus with higher acidity.

Pickling began as a way to preserve food for out-of-season use and for long journeys, especially by sea. Salt pork and salt beef were common staples for sailors before the days of steam engines. Although the process was originally used to preserve foods, pickles are frequently eaten because people enjoy the resulting flavor.

Indonesian Acar is usually made from sliced or diced cucumber, carrot, bird's eye chilies, shallots and seasoned with vinegar, sugar and salt. Sometimes Indonesians added other kinds of fruits, such as sliced/diced papaya and pineapple.
In the Philippines, they also have pickles called "achara" which is made from slices of green papaya, shallots, cloves of garlic and vinegar.
Europe
In Turkey, pickles are called "turşu." Turkish people make "turşu" with several vegetables, roots and fruits such as peppers, cucumber, Armenian cucumber "acur", cabbage, tomato, eggplant (aubergine), carrot, turnip, beetroot, green almond, green plum, and etc. Also, they use several spices to flavour their pickles.
In Bulgaria mixed pickles are known as turshiya. They are a very popular traditional appetizer for rakia. Also very popular are pickled tomatoes, cucumbers, peppers, zucchini, eggplants, and sauerkraut.
In Spain, pickled churros has recently become a popular dish.
In Romania, common pickles are cucumbers, green tomatoes (gogonele), carrots, cabbage, bell peppers, melons, mushrooms and cauliflowers.
In Russia, popular pickled food includes: mushroom, various types of tomato, cabbage, cucumber, ramsons, garlic, eggplant (typically stuffed with julienned carrots), custard squash, and even watermelon.
Pickled herring and rollmops are pickled fish dishes popular typically in Scandinavia. Salmon may be brine-pickled.
In Britain, pickled onions and pickled eggs are often sold in pubs and fish and chip shops. Pickled beetroot, walnuts, and gherkins, and condiments such as Branston Pickle and piccalilli are typically eaten as an accompaniment to pork pies and cold meats or a ploughman's lunch.
In Ukraine common garden produce is usually dilled to be consumed in winter. Salt, dill, currant leaves and garlic are used and, after storage in a cool, dark place, give tomatoes and cucumbers a distinctive flavour.
In Italy, giardiniera is a popular dish of pickled vegetables including onions, carrots, celery and cauliflower. Italian giardiniera is different from the American condiment called giardiniera.
Middle East
In Iran, as well as other Arab countries like Lebanon and Egypt, pickles (called mekhallel in Arabic, or torshi in Farsi) are served at almost every meal. They vary, but the most common are made from turnips, peppers, green olives, cucumber, beetroot, cabbage, and cauliflower.
North America
The United States and Canada pickle market is dominated by pickled cucumbers, olives, and sauerkraut, although many pickles popular in other nations are also available (such as the pickled tomato common in New York City delicatessens). Giardiniera, a mixture of pickled peppers, celery and olives, is a popular condiment in Chicago, often served with Italian beef sandwiches. Pickled eggs are common in the Upper Peninsula of Michigan. In the southern United States, pickled okra is popular. In Mexico, chile peppers, particularly of the Jalapeño and serrano varieties, pickled with onions, carrots and herbs are common condiments.
