Fruits & Vegetables
Fruits and vegetables are significantly vulnerable to temperature and relative humidity. Atmosphere conditions are important to extent products life and ensure high product quality.
Appropriate temperature in process and storage areas is crucial.
Inappropriate temperature can cause:
Relative humidity is another key factor. Fruits and vegetable consist mainly of water (almost 90%), for this reason they require high relative humidity 85-95%.
If relative humidity is not high water is extracted from the fruit leading to loss of weight, shrinkage and unpleasant view and finally damages the value of the product.
Produces that are ethylene sensitive may be ruined in the presence of ethylene or undergo unpleasant alterations in their physical characteristics. Some products suffer premature ripening (such as plants and cut flowers) or others turn yellow or brown (such as cucumber and celery). It is recommended never to store together ethylene sensitive products with products which produce ethylene.
Controlled atmosphere conditions:
Controlled atmosphere conditions aim to extend the product market life by lowering its respiration rate and eliminating CO2 and/or ethylene in case the product is sensitive to these substances.
