How To Store Opened Canned Vegetables So They Last Longer - Tasting Table
Briefly

Transferring leftover canned vegetables to food-safe containers is essential for maintaining freshness and preventing spoiling, such as bacteria growth or off-putting odors.
For peak freshness, choose containers with a good seal; this minimizes exposure to air and moisture which can lead to unpleasant surprises like discoloration.
Properly stored, low-acid canned vegetables can last three to four days in the fridge, while high-acid foods might last up to a week.
Glass containers won't retain smells or stains and are microwave-safe, making them an excellent choice for storing leftovers. However, plastic containers often seal tighter.
