Abstract
Controlled-release delivery compositions/systems are disclosed for use in the reduction in postharvest spoilage of fruits, vegetables, and plants by utilizing at least one matrix in which at least one volatile shelf-life extending agent is contained. Assemblies containing the controlled-release delivery composition/system, as well as methods of producing and using the controlled-release delivery composition/system, are also disclosed.
Claims21
A controlled-release delivery composition for extending life of at least one produce item, wherein the controlled-release delivery composition comprises:
- at least one volatile shelf-life extending agent, wherein the at least one volatile shelf-life extending agent is selected from the group consisting of an antimicrobial, an immunostimulatory compound, an ethylene inhibitor, and combinations thereof;
- and
- at least one matrix, wherein the at least one matrix is in a substantially solid or semi-solid physical state, wherein the at least one matrix is selected from the group consisting of an emulsifier, a wax, a polymer, and combinations thereof,
- wherein the emulsifier is selected from the group consisting of monoglycerides, diglycerides, fatty acids, fatty acid salts, fatty alcohols, lecithin, glycerol, sterols, and combinations thereof,
- wherein the wax is a beeswax, a lanolin, a Carnauba wax, a Candelilla wax, a Bayberry wax, a soy wax, or a combination thereof,
- wherein the polymer is a polysaccharide or a synthetic polymer,
- wherein the polysaccharide is selected from the group consisting of cellulose, pectin, chitosan, chitin, alginate, starch, carrageenan agar, shellac, hyaluronic acid, inulin, lignin, and combinations thereof,
- wherein the synthetic polymer is selected from the group consisting of polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, ABS, silicones, polyethylene glycols, poly-vinylacetate, poly-caprolactone, nylon, PVC, and combinations thereof;
- wherein the at least one volatile shelf-life extending agent is contained within the at least one matrix and released from the at least one matrix at a controlled rate;
- and
- wherein the controlled-release delivery composition is designed for positioning on at least a portion of at least one surface of the at least one produce item or for positioning within a container in which the at least one produce item is disposed.

- at least one volatile shelf-life extending agent, wherein the at least one volatile shelf-life extending agent is selected from the group consisting of an antimicrobial, an immunostimulatory compound, an ethylene inhibitor, and combinations thereof;
- at least one antioxidant selected from the group consisting of vitamin A, vitamin C, vitamin E, thiols, tocopherol, catechins, anthocyanins, polyphenols, resveratrol, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), and combinations thereof;
- at least one release-rate modifying agent selected from the group consisting of sodium salts, potassium salts, magnesium salts, calcium salts, ferrous fumurate, iron pyrophosphate, ferrous sulfate, ferrous fluconate, ammonium bicarbonate, ammonium sulfate, guanidinium chloride, macrocycles, and combinations thereof;
- and
- at least one matrix, wherein the at least one matrix is in a substantially solid or semi-solid physical state, wherein the at least one matrix is selected from the group consisting of an emulsifier, a wax, a polymer, and combinations thereof,
- wherein the emulsifier is selected from the group consisting of monoglycerides, diglycerides, fatty acids, fatty acid salts, fatty alcohols, lecithin, glycerol, sterols, and combinations thereof,
- wherein the wax is a beeswax, a lanolin, a Carnauba wax, a Candelilla wax, a Bayberry wax, a soy wax, or a combination thereof,
- wherein the polymer is a polysaccharide or a synthetic polymer,
- wherein the polysaccharide is selected from the group consisting of cellulose, pectin, chitosan, chitin, alginate, starch, carrageenan agar, shellac, hyaluronic acid, inulin, lignin, and combinations thereof
- wherein the synthetic polymer is selected from the group consisting of polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, ABS, silicones, polyethylene glycols, poly-vinylacetate, poly-caprolactone, nylon, PVC, and combinations thereof,
- wherein the at least one volatile shelf-life extending agent, the at least one antioxidant, and the at least one release-rate modifying agent are contained within the at least one matrix, and
- wherein the at least one volatile shelf-life extending agent is released from the at least one matrix at a controlled rate;
- and
- wherein the controlled-release delivery composition is designed for positioning on at least a portion of at least one surface of the at least one produce item or for positioning within a container in which the at least one produce item is disposed.
