Degradable Packaging Film For Fruit And Vegetables
The present invention relates to a degradable film for packaging fruit and vegetables, which comprises a polyolefin-based polymer matrix that incorporates an antimicrobial (biocidal or fungicidal) active ingredient of an essential oil, selected from the group consisting of: carvacrol, cinnamaldehyde, cineol, sabinene, thujaplicin, or a mixture of same, or incorporates the essential oil itself, selected from the group consisting of: cinnamon oil, oregano oil, eucalyptus oil, nutmeg oil, hinoki oil, or a mixture of same. The polymer matrix further comprises degrading agents. The invention also relates to a method for microencapsulating the antifungal or antibacterial active ingredients of the essential oil or the essential oil itself, and to a method for preparing the film.

- 1. Degradable film for packaging of fruits and vegetables with antimicrobial properties, comprising a polyolefin-based polymer matrix incorporating an active antimicrobial agent of essential oil selected from the group consisting of carvacrol, cinnemaldehyde, cineole, sabinene, thujaplicin or a mixture thereof or incorporating said essential oils selected from the group consisting of: cinnamon oil, oregano oil, eucalyptus oil, nutmeg oil, honokitioi oil or a mixture thereof, and wherein said polyolefin-based polymeric matrix is selected from the group consisting polyethylene (PE), polypropylene (PE), polystyrene (PS) and ethylvinylacetate (EVA), and wherein said polymeric matrix also includes a crosslinking agent selected nano calcium carbonate, calcium carbonate, starch, cellulose or a mixture thereof and wherein the nano calcium carbonate is also a reinforcing agent.
- 20. Process for microencapsulating one antimicrobial active of essential oil selected from the group consisting of: carvacrol, cinnemaldehyde, cineol, sabinene, thujaplicin or a mixture thereof or incorporates said essential oil selected from the group consisting of: cinnamon oil, oil oregano oil, eucalyptus oil, nutmeg oil, honokitiol oil or a mixture thereof, β-ciclodextirn, comprising:
a) solubilizing β-cyclodextrin in a water/ethanol solution 2:1 under constant stirring at a temperature of 55oC, and preparing separately a solution of the active agent of essential oil or said essential oil in 10% ethanol v/v; b) adding slowly the solution of said active agent essential oil or said essential oil to the solution with β-cyclodextrin, mixing 55oC then lower the temperature to 25° C. and stirring to thereby refrigerate to 7° C., allowing precipitation cold, and then filtered under vacuum to finally allow drying of the precipitate.
