What is Pickling Process?
Pickling is one of the oldest methods of food preservation. Before the invention of modern refrigeration, pickling was the only way to preserve various foods for future consumption. Generally, pickling began as a method to preserve foods that are either exotic or seasonal and limited by nature and cultivation.
The process of pickling can be generally traced back to India, as it is believed to have originated about 4,000 to 5,000 years ago. With hot summers and a lack of water during summers, food production decreased during the summer. Thus, there was a need to preserve excess food produced during winters and hence, the process of pickling was invented to overcome this problem.
The traditional way of preparing long-lasting pickles in the oriental style uses ingredients such as salt, oil, and dry chili powder mixed with condiments. These ingredients are added according to set proportions.
Popular Pickles around the World
In India, unripe fruits such as mangoes, Indian gooseberry, unripe tamarinds, and lemons are traditionally used. Apart from these, various vegetables such as gherkin, bitter gourd, carrot, cauliflower, ginger, garlic, onion, jackfruit, and citron are also pickled. In most cases, only one vegetable or unripe fruit is used for pickling. But occasionally, a mix of two or more vegetables or unripe fruits are also made. Generally, pickles made from vegetables and unripe fruits are prepared with utmost care so that they don’t spoil and can be preserved all year long. Non-vegetarian ones are also popular. These pickles are made from chicken, fish, prawns, and mutton.
In Asian countries such as China, pickles are very popular and have also been prepared for thousands of years. Chinese pickles include vegetables such as cabbage, lettuce, bitter melon, cucumber, carrot, and shallot. These and other vegetables are mixed with sugar and salt and put in vinegar. Apart from vegetables, eggs (particularly duck eggs) are stored by applying salt, earth, hay, and other ingredients and sealed to mature for about one month. Some pickling processes include soy sauce for instead of vinegar and in other varieties, condiments such as ginger, garlic, chili, or are also added for a hot and characteristic flavor.
In Korea, kimchi is a common pickled product that is made with fermented spicy cabbage and it also includes a wide variety of vegetables including soybean, fish, oysters and many different ingredients. The Korean pickling process owes its origins to Chinese, but unlike the common Chinese cabbage pickles, the Korean pickling process has its own variations according to the local flavor and available ingredients. Korean pickling processes usually involve two types, one in which the ingredients along with spicy chili pastes are fermented, while the other involves milder varieties pickled in water.
In a similar manner, even the Japanese have their own version of pickles, which include ingredients such as ginger, gingko nut, carrot, eggplant, radish, plum, green apricot, and soybean paste along with parboiled vegetables.

In the USA, New Zealand, Switzerland and many European countries, pickles are generally made from salted cucumbers, gherkins, and various vegetables which are soaked in vinegar. Apart from cucumbers and gherkins, fruits such as peaches, pears, and apples are also pickled. These pickles generally have sweet, sour, and salty flavor, while Indian pickles are generally pungent in taste.
Cucumber pickles can be generally divided into fermented or crock, fresh pack or quick process, andand freezer pickles.
Each of these pickles is made in different ways. For example, in fermented or crock pickles, either vinegar is added or the vegetables are preserved in salt brine for several weeks. Salt-resistant bacteria present in the vegetables help in converting the sugars into lactic acid, or the acetic acid present in the vinegar accelerates the process of fermentation. This is the reason why most cucumber pickles have sour and salty tastes.
Fresh pack or quick pickles, on the other hand, are also very popular, as they are very easy to prepare and are ready to eat. They are not fermented, but heated vinegar and salt solutions are poured onto the vegetables. Fruit pickles and relishes are also prepared in this manner.
Refrigerated and frozen pickles are prepared using the fermentation process. However, instead of storing them at room temperature, they are stored in refrigerators and freezers. In these frozen pickles, the vegetable slices remain crisp. (Ingham, 2002).

We can protect ourselves from these radical attacks by consuming food with high antioxidants.
Probiotic bacteria are those friendly bacteria that are present in our digestive system. These bacteria actually help us in the digestion of food. Sometimes, due to the use of antibiotics, along with invading bacteria, these friendly bacteria are also killed. The fall in their numbers can cause digestive problems that can be solved by eating pickles made without the use of vinegar. Naturally, fermented salt pickles encourage the growth of these friendly bacteria, which will replenish their numbers in our digestive system and restore our health.
