Homemade techniques to dehydrate fruit and vegetables

 

A very old method of preserving seasonal foods is to dehydrate fruit and vegetables. The farmers are experts in the use of these homemade techniques. In times of abundance of products, dehydration allows them to be available when they are no longer fresh.

Food alterations and decomposition are produced by the action of microorganisms and chemical and enzymatic reactions that occur in the presence of moisture. By removing that moisture, the problem is eliminated.

The technique of dehydrate fruit and vegetables consists of eliminating the water that the products naturally contain. In this way, the factor of deterioration and putrefaction, which is humidity, is eliminated.

No humidity, microorganisms that break down products do not work and processed fruit or vegetables last until needed. When it is time to consume it, it is rehydrated by keeping it in water for a while and it is ready to consume.
