If homemade canned yellow peaches are well sealed, they can generally be kept for three to six months. If you buy canned yellow peaches, you can keep them for 24 months. Bought canned yellow peaches with preservatives and other additives, and a good seal, so the shelf life of 24 months. Homemade canned yellow peaches are prone to spoilage because there are no preservatives added, so it is best to store them in the refrigerator. Once the cans are opened for consumption, try to finish them within a short period of time.
