Question

how are they preparing pickles? what are the causes involved in that? ​

Answer 1

Answer:

Pickles can be prepared using one of two main methods: lactic acid fermentation of vegetables, either with or without the addition of salt the preservation of vegetables in acetic acid (vinegar). The products made by these two methods are very different -each one has its own distinctive taste and texture.

Answer 2

It may be a normal reaction during fermentation caused by bacteria. If the pickles are soft, they are spoiled from the yeast fermentation. Don't use them. Using too weak a salt brine or vinegar solution may cause soft or slippery pickles, as can using moldy garlic or storing the pickles at too warm a temperature.
