Pickles made from mango and other vegetables are preserved using oil and vinegar. This prevents the spoilage of pickles as oil forms a hydrophobic layer on them, thus preventing the growth of bacteria which otherwise would grow in moist conditions.

Use of oil and vinegar prevents spoilage of pickles because bacteria cannot live in such an environment.

Pickling often involves heating or boiling so that the food becomes saturated with the pickling agent. Fermentation pickling involves microorganisms (starter culture or natural culture) that on growth lower the pH to such a point that bacteria will not grow.

Pickling preserves food in a solution of vinegar, salt, and sometimes sugar. This acidic environment prevents the growth of bacteria, making the pickled food safe to eat and extending its shelf life.

Preservation by Oil and Vinegar Use of oil and vinegar prevents spoilage of pickles because bacteria cannot live in such an environment. Vegetables, fruits, fish, and meat are often preserved by this method.

The oil used in the pickle forms a layer between air and pickle to protect it against the bacteria in the air. This will help to increase the life of the pickle and doesn't allow the bacteria to destroy the pickle.

Vinegar lowers the pH, creating an acidic environment that inhibits bacterial growth, while sugar reduces water activity, preventing bacteria from thriving. This combination effectively extends the shelf life of food products.

Vinegar can repress microbial growth in pickles (Adams, ¹⁹⁹⁸); however, its relatively low concentration used for preparing vinegar‐type senmaizuke (approximately 0.3% acidity) may allow microbial growth, which can affect the flavor and shelf‐life (spoilage).

During the canning process, air is driven from the jar and a vacuum is formed as the jar cools and seals, preventing microorganisms from entering and recontaminating the food. It does not take long at 212 degrees Fahrenheit, the temperature at which water boils, to force air out, create a vacuum and seal a jar.

The chemistry behind using vinegar to preserve food is straightforward. The vinegar's acetic acid raises the acidity of the vegetables, killing any microbes and effectively preserving the vegetables by preventing rotting.

What is the principle behind pickling using vinegar? ›

The main principle of pickling is to add an acid such as vinegar or lemon juice to reduce the pH to low acid foods. The pH range is usually below 4.6. Acid foods include such as tomatoes – green ones work better, all hard vegetables – such as zucchini, onions, cucumbers, cauliflowers, eggplant and so on.

Vinegar: Use white distilled or cider vinegars of 5% acidity. Any kind of vinegar with unknown acidity should not be used. White vinegar is usually preferred when a light color is desirable. The level of acidity in a pickled or fermented product is as important to its safety as it is to taste and texture.

Vinegar is a 5% to 10% aqueous solution of acetic acid that is used for food preservation as well as for flavouring. The acid has the ability to kill a variety of microbes that cause food spoilage. Vinegar keeps pickles from spoiling because bacteria cannot live in such an environment.

Salt is a critical ingredient for fermented products. It helps to prevent undesirable bacteria from growing so desirable bacteria can produce lactic acid needed for preservation.

Exposing foods to an adequate amount of salt during brine pickling prevents the growth of undesired microorganisms while allowing lactofermentation microorganisms to thrive, creating an acidic environment that preserves the food being pickled.

Complete answer: The salt form of Benzoic acid i.e. Sodium benzoate is one of the most common chemical food preservatives. Sodium benzoate is a common preservative used in acidified food such as fruit juices, jams, pickles, preserves, fruit co*cktails, etc. Yeasts' growth is inhibited by benzoate to a greater extent.

Either way, the vinegar's acetic acid will increase the the vegetables' acidity and kill off any existing microorganisms, which will help prevent prevent short-term spoilage.

Vegetables, fruits, fish, and meat are often preserved with oil and vinegar.It prevents the growth of bacteria as they cannot live in such an environment.

The science of using vinegar for food preservation is simple. The acetic acid contained in the vinegar increases the acidity of the vegetables, killing off any microorganisms and effectively preserving the veggies by preventing spoilage.
