How to Prevent Peach Discoloration

Overview

Peach discoloration can happen for many reasons. Certain chemical sprays may cause the peach to discolor while it is still on the tree. And after harvest, peaches must be handled with care to ensure that discoloration does not occur before they can be sold or consumed. Read on to discover how to prevent peach discoloration from afflicting your crop.

Step 1

Refrain from using foliar sprays or fungicides when your peaches are nearing maturity. These sprays contain metal residues that can discolor peach skin even before it is harvested.

Step 2

Take care when harvesting your peaches. Dropped, squeezed, pinched, rubbed and tossed-around peaches are more likely to develop discoloration.

Step 3

Use plastic baskets to collect peaches. Contact with hard wooden baskets increases the likelihood that your peaches will become bruised and discolored.

Step 4

Dip harvested peaches in absorbic acid before storing them. Absorbic acid can be found in crystalline or tablet form in many stores. Add 1/2 teaspoon (approximately 1500 milligrams) to a quart of water. Dip each peach in the solution for one minute. Allow their skin to dry before storing them.
