2.3. Peeling evaluation
2.3.1. Peeling performance
Indicators of the peeling performance consisted of four criteria,
namely the peelability, skin remaining, peeling yield, and moisture
loss. The peelability was used to quantify the degree of peel
removal (Li, 2012), and was calculated as the area ratio of removed
skin (i.e., peel removal by pressurized water spraying and hand
scrubbing) to the overall surface area of the peach. The area of the
