Fresh produce is preserved by coating the exterior surface of the produce with a coating composition comprising an aqueous solution of from about 1 to about 20 percent by weight of substantially hydrolyzed cold water insoluble polyvinyl alcohol, about 0.1 to about 10 percent by weight of low molecular weight cold water soluble starch, and about 0.03 to about 5 percent by weight of surfactant. Optional constituents include antimicrobials and plasticizers. The coating composition is effective to control respiratory exchange, i.e., the passage of gases, particularly oxygen, ethylene and carbon dioxide, into and out of the produce, thereby to control maturation and ripening of the produce.
A process for preserving fresh produce comprising the step of coating the exterior surface of the produce with a coating composition comprising an aqueous solution of from about 1 to about 20 percent by weight of substantially hydrolyzed cold water insoluble polyvinyl alcohol, about 0.1 to about 10 percent by weight of low molecular weight cold water soluble starch, and about 0.03 to about 5 percent by weight of surfactant.
A coating composition for the preservation of fresh produce comprising an aqueous solution of from about 1 to about 20 percent by weight of substantially hydrolyzed cold water insoluble polyvinyl alcohol, about 0.1 to about 10 percent by weight of low molecular weight cold water soluble starch, and about 0.03 to about 5 percent by weight of surfactant.
A coating composition for the preservation of fresh produce comprising an aqueous solution containing by weight percent from about 1 to about 10% substantially hydrolyzed cold water insoluble polyvinyl alcohol, from about 0.1 to about 5% cold water soluble starch, from about 6.03 to about 1.5% surfactant, and from about 0.05 to about 5% antimicrobia.
