Interpretive Summary:

Technical Abstract: In spite of the booming market for fresh cut fruit, fresh cut citrus has not been successful commercially due to technical difficulties in peeling the fruit. The USDA and the FDOC have developed a process using enzyme infiltration under vacuum to facilitate citrus peeling. However, the enzymes (cellulase and/or pectinase) continue their lytic action on the slices after the peeling process, hence degrading the slices during storage. The objective of the present study was to investigate solutions to stop enzymatic activity after peeling of Valencia oranges. Also, the enzyme infiltration system was compared to infiltration with water only, a process proven successful in the collaborating laboratory in Italy.
