It's a common kitchen conundrum: You're whipping up a hearty chili or anItalian tomato sauce but find you only need half the can of black beans or just a tablespoon or two of tomato paste for the recipe. Perhaps you've opened a can of pineapple slices for a fruit salad but don't need to use the entire can, or you're making a stir-fry and want to add a few canned corn kernels. So, what should you do with the open can? Is it necessary to transfer the contents to an airtight container, or will plastic wrap or a silicone lid over the can suffice in the refrigerator for a few days? And, if you go the can-storage route, is it safe? It appears that experts seem to agree that storing an open can of food in the refrigerator doesn't present a major health concern. Still, it may not be the best option for your leftovers.
Canned foods typically come in standard-sized containers, and if you're cooking for a smaller number of people or making a recipe that doesn't require the entire can, you'll use only a portion and need to store the rest for later use.Critics say storing an open can of food in the fridge can be problematic for a few reasons, primarily related to food safety and food quality, but the facts don't necessarily back up that argument.
An oft-repeated reason to avoid sticking an open can in the fridge is that chemicals from the metal can and packaging could seep into the food and contaminate it with Bisphenol-A (BPA). This synthetic compound has hormone-like properties, which can build up in humans and potentially affect metabolism and disease rates.
However, the U.S. Food and Drug Administration maintains that, at currently approved levels, any BPA present in cans or containers is safe. The agency continues to review new data on the subject. "We reassure consumers that current approved uses of BPA in food containers and packaging are safe," the agency reports on its website, adding, "FDA continues to monitor the scientific literature for new research that helps enhance our understanding of BPA, and will consider new data as it continues to ensure the safe use of BPA in food packaging."
There is also the possibility that a particularly acidic food — think stewed tomatoes — could trigger a chemical reaction that breaks down the inside of the can and actually dissolves away some of the metal. However, these foods will typically have a shorter shelf life than their low-acidity counterparts, and that sort of corrosive effect can take years, according to the USDA.
Preserving Flavor And Taste
Another argument among the anti-can-in-fridge contingent has more to do with the flavor and taste of the food. Storing an open can in the fridge can leave the food inside tasting tinny or "canned," Cornell University food microbiologist Carl Batt told ScienceNotes.org. He added that, without a good seal, the canned item is more likely to dry out or absorb potentially funky odors or flavors from its fridge neighbors.
But the bottom line is best covered by the USDA's Food Safety and Inspection Service, which offers a definitive answer to our original question: "Unused portions of canned food may be refrigerated in the can, but to preserve optimum quality and flavor, place the unused portion in a glass or plastic storage container." If refrigerating a can, the agency encourages consumers to cover it with some sort of lid and to be sure to eat the food within four days.
Of course, there is always the option to transfer canned contents into a glass or plastic container, which provides a better seal against air and contaminants, reducing the risk of spoilage and foodborne illness. Additionally, glass or plastic containers won't react with the food, preserving its flavor and quality.
Information. Yes. Unused portions of canned food may be refrigerated in the can, but to preserve optimum quality and flavor, place the unused portion in a food-grade glass or plastic container. Use within 4 days.
Low-acid canned goods, such as meat, poultry, fish, gravy, stew, soups, beans, carrots, corn, pasta, peas, potatoes and spinach) can be stored three to four days. Although it's safe to store the food in the can, it will retain better flavor if transferred to a glass or plastic storage container.
If you decide to put a half-full can in the fridge, it's important that you cover it well. Never leave the opened uncovered can sitting there on the shelf to absorb smells from other foods. Or worse, have something fall inside.
And the real reason you shouldn't leave open cans. in the fridge is because some of the tin and plastic. from the edge of the open can can seep into your food. This can be especially true.
Unopened canned corn can be stored in the pantry for 2-5 years from the date of purchase. After opening, store in the refrigerator for 3-4 days. Did you know? Canned corn is fully cooked, so it is safe to eat without further cooking.
Open beans can be stored in the refrigerator for 3 to 4 days; while it may be tempting to store them right in the can, the USDA recommends transferring them to plastic or glass containers. Beans have a low acid content and this makes them slightly more perishable than more acidic canned foods.
If you regularly refrigerate foods unwrapped or uncovered, you may want to ditch the habit, says Le. Some microorganisms (such as molds and yeasts) can thrive in the cold temperature of the refrigerator, where they can circulate in the air and land on food.
Low-acid foods are the most common sources of botulism linked to home canning. These foods have a pH level greater than 4.6. Low-acid foods include most vegetables (including asparagus, green beans, beets, corn, and potatoes), some fruits (including some tomatoes and figs), milk, all meats, fish, and other seafood.
Metal containers: You will not often find metal containers meant for the fridge. You need to be mindful of what type of metal you use to store food inside the fridge. It is generally recommended to use a 100% stainless steel container to store food if using it as a fridge container.
Your pet's bowl should be emptied of moist or canned food not eaten by your cat or dog within 4 hours if the ambient temperature is above 50°F. Opened cans should be stored in the fridge, at temperatures between 40-45°F, for a maximum of 5-7 days. Any cat or dog food remaining after that time should be thrown out.
Eventually flavor and carbonation will decrease. For best quality, consume unopened diet sodas within 3 months after the date expires; regular sodas within 9 months. After opening, sodas may be safely stored in the pantry or refrigerator.
Store in a cool, clean, dry place where temperatures are below 85 F (between 50-70 F is good) but not freezing temperatures. Rotate foods so the oldest is used first. Try not to keep canned foods more than 1 year. Use canned meats and seafood within 3 years of the date on the package.
An oft-repeated reason to avoid sticking an open can in the fridge is that chemicals from the metal can and packaging could seep into the food and contaminate it with Bisphenol-A (BPA). This synthetic compound has hormone-like properties, which can build up in humans and potentially affect metabolism and disease rates.
It's best to use your corn the day you buy or harvest it. However, you can keep it fresh longer by storing it, unwashed and unpeeled, in a sealed plastic bag in the crisper drawer of your fridge.This'll keep it usable for about five to seven days.
Once you buy your fresh corn, it's important to keep it cool and humid—no matter if you bought it refrigerated at the grocery store or fresh from the farmers market. “Store in the fridge and in the husk until use,” says Walczak.
While opening the jar, smell for unnatural odors and look for spurting liquid and cotton-like mold growth (white, blue, black, or green) on the top food surface and underside of lid. Spoiled low-acid foods, including tomatoes, may exhibit different kinds of spoilage evidence or very little evidence.
In most cases, the reasons for canned food going bad are: Exposure to air, leading to bacteria growth. High humidity or moisture in the air, causing mold. Hot weather, leading to rancidity.
Leftovers can be kept for 3 to 4 days in the refrigerator. After that, the risk of food poisoning goes up. If you don't think you'll be able to eat leftovers within four days, freeze them right away. Frozen leftovers will stay safe for a long time.
High-acid canned goods such as tomato, juice, fruit, pickles, sauerkraut and foods in vinegar-based sauces can be stored 5–7 days. Low-acid canned goods, such as meat, poultry, fish, gravy, stew, soups, beans, carrots, corn, pasta, peas, potatoes and spinach can be stored 3–4 days.
