d) Salting is used for preserving pickles.
Salting
- Pickles are Indian savoury foods made from raw vegetables and fruits. This makes them prone to attack by bacteria and it may foul easily.
- In order to slow down or even eliminate the fouling process, NaCl salt is added to pickles and savoury foods.
- This makes the food items preserved for a considerably long duration. Oil may also be added to make it inert from the atmospheric fouling.
Incorrect options
- a) Pasteurization is a prevalent practice of milk sterilization and is not used for pickle preservations.
- b) Sterilization is the most commonly practised process of making an object free of microbes to a huge extent. It can be done by heating.
- c) Refrigeration is also a preservation step but is not used for pickle preservations.
