When transporting food, specially fruits and citrus, these tend to oxidize as time passes due to the moisture and different temperatures found in the environment.

There is a treatment or coating that is given to these citrus fruits so that they last longer and be resistant to the oxidation, as well as to maintain their freshness and gloss.

At Polímeros Sinteticos we manufacture gum rosin derivatives specialized for the fruit coatings and their treatment, such as fumaric resins, which due to their natural origin have FDA acceptance.
