The natural pH of white peaches or nectarines can exceed 4.6, making them a low-acid food for canning purposes and a potentially hazardous food, therefore not allowed as a cottage food product.
Can white nectarines be canned?
The natural pH of some white-fleshed peaches or nectarines can exceed 4.6, making them a low-acid food for canning purposes. At this time there is no low-acid pressure process available for white-flesh peaches or nectarines, or research to support adding acid for safe boiling water or atmospheric steam canning.
Can nectarines be canned?
If you’re canning a lot of nectarines, you can pack the hot nectarines in quart-size jars and then process them for 25 minutes. Unlike peaches, nectarines don’t really need to be peeled before canning, but feel free to do so if you wish.

What is the difference between peaches and nectarines?
