PRESERVED BY REDUCING WATER ACTIVITY

Scope note

Description


Preservation method that lowers the water activity (relative humidity) of a food product. This is accomplished by using mechanical dehydration equipment, by natural drying, by adding salt, sugar or other agents to the food or by surface drying during a refrigeration or freezing operation. This method of preservation may be used in conjunction with other preservation methods such as preservation by thermal processing.
