Question

which measures will you suggest to prevent the decaying of vegetables

Answer 1

There are many mechanisms of prevent the decaying of vegetables. Following are the list of preservation methods :

• Refrigeration & Freezing : In this method, micro-organisms like bacteria and fungi stop growing. Because in low temperature, their growing process gets slow down.
• Canning and bottling : In this method, fruits and vegetables are kept in airtight container. So that no more micro-organism can get into in it.
• Drying : In this method, drying dehydrates fruits and vegetables and then kept into sealed container. As we know, micro-organisms needs moisture to grow and in dried foods they cannot grow.
• Chemical preservation : In this method, some safe chemicals like salt, oil, sugar or vinegar can be added to food to stop the bacteria and fungi from feeding and growing.

Answer 2

The process of breaking down or decomposition is called decay. Vegetables become inedible after they decay.

There are four types to prevent the decay of vegetables. They are,

• Salting
• Canning
• Pickling
• Freezing

Salting is also called as the drying method of preservation. Excess salt is added or rubbed over the vegetables as it reduces moisture and hence, delays decaying.

Canning of vegetables is another effective method of vegetable preservation when cans or glass jars are used. They prevent entry of decomposers.

Pickling is the process of preservation by turning the vegetables into pickles. The vegetables are placed in a jar containing vinegar where they undergo fermentation process which boosts the vitamins.

Freezing is the process cooling the vegetables beyond their freezing point. Once they are frozen, no decomposers can feed on the frozen vegetables.
