Does Vegetable Broth Need to Be Refrigerated? Opened or Unopened

[Vegetable Broth Storage: Professional Guidelines for Refrigeration and Shelf Life]

The carton of vegetable broth has sat in the pantry for months without a problem. Then you open it for tonight’s soup, use a cup, and stare at the rest. Does it go in the refrigerator? What about the jar of stock you simmered from carrot ends last weekend? The answer depends on which kind of broth you have and whether it has been opened. Here is what USDA, extension, and brand guidance says, and how to read your label.

Does vegetable broth need to be refrigerated?

The Short Answer: Opened vegetable broth needs to be refrigerated, and so does homemade broth. Unopened shelf-stable broth, the kind sold on the ordinary pantry shelf, doesn’t need refrigeration until it is opened. Broth labeled Keep Refrigerated or Keep Frozen needs cold storage even before opening. After opening, refrigerate it promptly and follow the time on your label. With no label time, 3 to 4 days is a conservative default based on USDA’s general guidance, which has no separate time for opened broth cartons. Refrigerate homemade broth within 2 hours, or 1 hour when the air is above 90°F. Extension recipes give it 3 to 4 days.

Key Takeaways

• USDA’s Shelf-Stable Food Safety page defines aseptic packaging as a process that keeps microorganisms out of a package: a commercially sterile food is filled into a sterilized package and sealed in a hygienic environment. It names soups and broths among aseptically packaged products and says to store shelf-stable foods in a cool, dry place.
• The same page says unused portions of opened canned food must be refrigerated and may stay in the can, though glass or plastic is better for quality. It lists opened low-acid canned food, which includes soups, at 3 to 4 days.
• USDA’s Keep Food Safe chart has no vegetable broth row. It lists soups and stews at 3 to 4 days in the refrigerator, and it says to refrigerate perishable food within 2 hours, or 1 hour above 90°F.
• Oregon State Extension and a University of Maine Extension recipe sheet both give homemade vegetable broth or stock 3 to 4 days in the refrigerator. Both say to save vegetable scraps for broth in the freezer.
• The manufacturer FAQs and product-label directions we read give opened times of 4 to 14 days. These are product-specific manufacturer directions, so follow your own label.
• USDA says hot food can go directly into the refrigerator or into an ice or cold water bath first, so homemade broth doesn’t need to cool on the counter. It also says to divide a large pot into smaller containers.

How to Tell Which Kind You Have
As a rule of thumb, which is our own reading, a carton on an ordinary shelf whose label says to refrigerate after opening is shelf-stable. A carton whose label says keep refrigerated or keep frozen needs to stay cold even before opening. Store placement alone doesn’t settle it. If you can’t tell, read the label, and if it still isn’t clear, we’d keep it cold while you check with the manufacturer, which is our own suggestion. Concentrates, pastes and bouillon are different products with their own labels. For a related staple, see whether gravy needs to be refrigerated.

Does Unopened Vegetable Broth Need to Be Refrigerated?

Not if it is shelf-stable. USDA’s Shelf-Stable Food Safety page defines aseptic packaging as a process that keeps microorganisms out of a package during and after packaging. A sterilized package is filled with a commercially sterile food and sealed in a hygienic environment. In the cartons USDA describes, a thin aluminum layer also blocks light and oxygen. Together, the sterile food
