I am living in very moisture and humid environment. The eatbles I bought like rusk(made of wheat and vegetable oil), capture moisture within a day and then become unfit to eat. What should I do so that these eatables can stay longer without affecting by moisture and humidity?

I've lived in tropical climates for many years. We stored things like rusks, cookies, biscuits, and the like in air-tight containers. I'd have a large air-tight container for keeping large quantities in which is only opened infrequently, then a smaller one that stores smaller quantities for more frequent access. It's not perfect, but it does mean these products are still good for a longer period of time than if we did nothing.

  • Thanks LMAshton. That's what I want so instead of changing environment which is very costly.we can do this, to preserve our food material. – vivek Jun 21 '16 at 7:19

There is nothing you can do about the food and keep it the same. So you will have to change the environment. The easiest way would be to get a fridge capable of supporting temperatures in the 15 to 20 Celsius range and use it as a pantry. It will be cool, dark and dry, so the ideal pantry environment. If you have the space, you can choose to keep it in your normal fridge or freezer instead.

The one category for which making conserves will work is fruit and vegetables. So instead of storing apricots, you can cook apricot jam. This has the downsides of 1) the end product being very different from the original, and 2) not being applicable to typical pantry items like your rusk. So you still need to find suitable storage space for those. There is no way to simply stop them being affected by the environment.

  • Thanks for replying. If you can please tell what this suitable storage for rusk and biscuits like items. – vivek Jun 19 '16 at 3:12
  • The best storage is 15 to 20 Celsius and about 40 to 50% relative humidity. They can be stored in a wider range of temperatures and humidity (most European pantries don't have these conditions either), but you have to find out yourself if a given place is good enough or not good enough. – rumtscho Jun 19 '16 at 10:30
