is a reference to the amount of moisture present in a material
Moisture content (MC)
isthe presence of a liquid, especially water, often in trace amounts. Moisture is defined as water in the adsorbed of absorbed phase.
Moisture
the art of measuring the moisture content of air
Psychrometry
is the ambient air temperature that is measured by regular thermometers
The dry bulb temperature
is measured by thermometers that are wrapped in wetted wicks.
The wet bulb temperature
is a measure of the water vapor content of air.
Relative Humidity (RH)
isthe removal of unwanted heat from a selected object, substance, or space and its transfer to another object, substance, or space.
Refrigeration or cooling process
(sometimes called “refrigerated warehouses“) aredesigned for preserving the integrity and shelf life of products that don’t need to be frozen.
Cold storage facilities
It is defined as any processing activity that is or can be done on the farm or by local enterprises in which the farmer has an active interest.
Agricultural processing
It is the general term applied to the handling of crops, whether used for food or other purposes such as seeds, fiber, botanical pesticides and the like, from harvest up to the time they reach the final consumer. It is subdivided into two: primary and secondary processing.
Postproduction
Any activity that involves the handling of crops to make them more suitable to manufacturers, processors or consumers and can still be changed into other forms. The original plant part can still be recognized. It includes raw material handling and minimal processing.
Primary Processing
the postharvest handling of fruits and vegetables specifically intended for food processing, and of florist crops for making dried art forms.
Raw material handling
is the postharvest handling of fruits and vegetables that have been peeled, sliced, cut and packaged in a form that is ready to cook or to eat uncooked.
Minimal processing
A postproduction activity that involve conversion of harvested crops into stable products that can no longer be changed into other forms.
Secondary Processing
Secondary processing
It is also referred to as full processing
