Possible fields of applications for moisture regulating films are fresh
fruits, fresh vegetables, minimally processed food and ready-to-eat meals that are sensitive to
microbial deterioration. The moisture regulating films could help to prevent food waste.
Moisture absorbers
bind water vapour or liquid water, thereby preventing the (food) product from absorbing water
These salts have the ability
to absorb large amounts of water vapour when the RH exceeds a certain value. Different salts have differing absorption properties, and hence the optimum
humidity for storing products can be set by careful selection of the salt
