Shelf life. Commercial sugars (granular, syrup, and honey) have an indefinite shelf life due to their resistance to microbial growth. However, sugars have a best-if-used by date of approximately 2 years for quality concerns.
Sugar, particularly granulated white sugar, does not have a strict expiration date. It can last indefinitely if stored properly in a cool, dry place in an airtight container. Over time, sugar may clump or harden, but it is still safe to consume.
The first way is to check the color of the sugar. If the sugar is brown, it means that it has been exposed to oxygen and is no longer good. The second way to tell if your sugar is bad is to smell it. If the sugar smells sour, it means that it has gone bad. The third way to tell if your sugar is bad is to taste it.
Most white sugars have a best use-by date of about 2 years. After 2 years of being stored in the original packaging, the white sugar may start to clump a bit but it is still just as good to use. If you store your white sugar with optimal storage methods, it will put off clumping much longer.
Granulated sugar can last up to two years in the pantry after opening. Technically, sugar never spoils. While it's recommended that granulated sugar be discarded after two years, chances are it will still serve its baking purpose even beyond that.
However, sugars have a best-if-used by date of approximately 2 years for quality concerns. This is due to lumpiness or hardening in granulated sugars and crystallization of sugars in honey and syrup. It is still safe to use even when lumpy or crystals are present.
All flour has a printed “best by” or “best if used by” date somewhere on the package. This date reflects the manufacturer's suggested date for best quality. You can generally use flour for four to six months past this date, depending on how you've stored it—more on that below!
Psocids (or flour weevils) are tiny brown or black insects which live in dry foods, including flour and sugar.
Baking soda and baking powder are both essential pantry staples for bakers. They have long shelf lives, but can they go bad? The answer is yes. Both baking soda and baking powder will eventually expire.
Essentially, brown sugar hardens when moisture evaporates due to aging or improper storage. But hardened sugar is still safe to eat and use—you just have to soften it back up to a usable texture. If your recipe has the sugar dissolving or melting into a liquid, you can actually use the hardened stuff without issue.
All brown sugars, and for that matter, granulated and powdered sugars, have an indefinite shelf life as they do not support microbial growth. Sellers are required to stamp on their product's bag a 2-year "Best By" date — not a "Use By" date — but it is still safe to consume after that.
Generally speaking, consuming sugar past its expiration date is not a safety issue. Sugar is a stable substance and doesn't harbor bacteria or mold like other foods. The lack of moisture in sugar acts as a deterrent against microbial growth, making it unlikely to become unsafe for consumption over time.
The answer is a definite yes. However, the expiry date is not an absolute indicator of when you need to replace your oil. The expiry date is simply the point at which the motor oil loses its lubrication properties.
Real Salt never expires.
Food only spoils when fungal, bacterial, yeast, or other microbial growth takes place. All of these require water. Salt doesn't contain water, so it doesn't support microbial growth, meaning it won't spoil. In fact, salt is actually used as a preservative for other foods, like meat.
With sell-by dates and expiration dates displayed on packaging, it's easy to assume that all foods—even shelf-stable pantry items—eventually expire. Not so with sugar! According to Domino Sugar, "Sugar... has an indefinite shelf life because it does not support microbial growth."
It has an indefinite shelf life that doesn't technically expire but will degrade in quality over time. If sugar sits in your cupboard too long, it is likely to crystalize and harden. The color and flavor can change too, so it is recommended to use sugar within two years.
“Because sugar is water soluble and harmless, it can go down the drain and not cause blockages, unlike some other materials used in hand cleaners,” said Dr. Francesca Kerton, professor of Green Chemistry at Memorial University of Newfoundland in Canada. “Table salt is an ingredient in some scrubs.
Description. African black sugar ants are a shiny dark brown ant about 2–3 mm in length. The ants are covered in thick blackish bristles and there is a pronounced spine between the thorax and abdomen (these features are only visible under a hand lens or microscope).
Weevils: Weevils are tiny beetles that can find their way into packaged dry goods, including sugar. These pests lay their eggs in the packaging, and once hatched, the larvae can wreak havoc on your sugar stash.
When brown sugar is exposed to air, the moisture in the molasses evaporates, and that is what makes brown sugar hard—the sugar crystals stick to each other as the molasses dries out and becomes a solid mass.
Wheat-based refined flours usually can be used past the expiration date (up to a year at your house), especially if it's been stored in a cool, dry place. 2 You'll want to be careful about self-rising flour, though, as the baking powder that's mixed into the flour can lose its effectiveness over time.
Storing Cornstarch
Despite any date you might see on the package, cornstarch shouldn't go bad or lose its power. As long as you keep it in a cool, dry place, free from moisture, it should last indefinitely on your shelf—that is, if you don't use it up quickly.
If it's expired by several months, it's probably best to toss it. If you're close, you can always proof the yeast to see if it's still active. But if it looks a little sluggish, you might not get enough yeast-y action to make anything.
