Abstract
Disclosed herein are embodiments of a composition for use in forming films or coatings that prevent damage in foodstuffs, including plants, fruits, and vegetables. The disclosed compositions comprise a cellulose nanomaterial and can further comprise a nanoscale mineral compound and one or more additional components. Also disclosed are films or coatings made using the disclosed compositions, as well as methods for making the disclosed compositions and methods for using the disclosed compositions.
Claims19
A plant, fruit, vegetable, or part thereof, coated with a film formed from a composition comprising 0.188 wt % to 2 wt % of a cellulose nanomaterial comprising cellulose nanofibrils, cellulose nanocrystals, or a combination thereof and further comprising cellulose microfibrils, cellulose microcrystals, or a combination thereof;
- wherein the film formed from the composition prevents or mitigates pre- and/or post-harvest damage in the plant, fruit, vegetable, or part thereof.
A method of treating a plant, fruit, vegetable, or part thereof, comprising coating the plant, fruit, vegetable, or part thereof, before or after the plant, fruit, vegetable, or part thereof is harvested, with a composition comprising 0.188 wt % to 2 wt % of a cellulose nanomaterial comprising cellulose nanofibrils, cellulose nanocrystals, or a combination thereof and further comprising cellulose microfibrils, cellulose microcrystals, or a combination thereof to provide a film that prevents or mitigates pre- and/or post-harvest damage in the plant, fruit, vegetable, or part thereof.
A method for processing a coated plant, fruit, vegetable, or part thereof, comprising thermally processing the coated plant, fruit, vegetable, or part thereof at a temperature of at least 80° C., which coated plant, fruit, vegetable, or part thereof is coated with a film formed by a composition comprising 0.188 wt % to 2 wt % of a cellulose nanomaterial comprising cellulose nanofibrils, cellulose nanocrystals, or a combination thereof and further comprising cellulose microfibrils, cellulose microcrystals, or a combination thereof.
