Abstract
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.
