Default Shelf life of peanut butter...



Advertise Here

with sugar,etc or without? vs. buying peanuts in the shell and bagging them in mylar? I love peanut butter! I know that storing bags of peanuts give you more versatility...

I think generally it's 2 - 3 months after opening and most have a 1 - 2 year 'best buy' date - 'natural' PB, much less.
If I were going to store whole peanuts it would be in the freezer.

Natural brands with nothing but peanuts are about a year.

Common store brands swap out for other oils and get loaded with preservatives are good for a couple years.

Skippy Natural Spread uses palm oil instead and is good for 3 or 4 years. (Freeze for longer)

Defatted peanut flour is good for 5 or 6 years in mylar that you can mix up with coconut oil.

Went though that tonight realizing we were down to 6 jars. Exp date is 2 years from date of purchase.

We're buying Jiffy as that's what my better half likes. Honestly, down to six jars spooked me. We have over 9 months worth of food stored here and similar at the BOL, but the lack of peanut butter got me a bit concerned.

Ordered more Jiffy 2 packs and will continue to by more as rationing allows.

Also, natural brands, as they sit on the shelf, will have more oil rise to the top. Just stir it back in.

Buy natural brands to eat, not store. They don't store up long enough to stockpile.

PB lovers should buy both eating and storing PB, and they are not the same product.

I know. I tend to buy 3 jars at a time. Even at 2 or 3 weeks, by the time I get them from the store, they're oily on top.

I have a small jar of an off brand called Algood Creamy Peanut butter. 18 oz, It's been open for about 2 years now. Best buy date Oct 03 17. I've ate about a quarter of it. Still good after all these years. I get a teaspoon every great once in a while when I get a hankering for some peanut butter. No bad taste yet and no oil has floated to the top all this time.

Ingredients list states. Roasted Peanuts, Sugar, Contains 2% or less of Fully Hydrogenated Oils (Cottonseed, Soybean, Rapeseed) Monoglycerides, Molasses, Honey, Dextrose and Salt.

Manufactured by AlGood Food Company Louisville, Kentucky Made in the U.S.A.

I'm not a big peanut butter fan but every once in a while I get a craving for a taste. I get me a teaspoon full and i'm good to go for a while.

I got regular PB for my husband, soy and sunflower (not together) for me because PB gives me migraines. I was happy I did score all of it when I did.

It's never lasted long enough in our house to find out. Usually the best by date was put there by the manufacturer top scare people into throwing away perfectly good food and buying more food. My wife worked at a senior care center and they always had to throw food away once it hit the best by date. Complete waste of food. Needless to say a good share of it wound up in my cupboard.

Peanut butter is one thing that often tastes old when it goes past the dates. The oils and fats don't last well.

I agree with you though, "best by" dates are NOT "expiration" dates.

I have discovered i use a lot of peanut butter while hunkerd down. Like on track to use a 5 pound jar in less than 2 months pretty much on my own. Peanut butter is scarce now, i avoid the spreads with hydrogenated fat which are most of them and go for adams just peanuts and salt or natural peanut butter with palm oil. Have to start rationing.

The best by dates are there because regulations require it. Simple as that. And in the case of canned foods, several of the manufacturers themselves have come out and said their food is safe to eat far in excess of their best by dates. As long as the can remains sealed, the food can't rot or spoil.

As for peanut butter, it only lasts as long as the oils would last by themselves. Doesn't matter if it's a bottle of peanut oil or a jar of peanut butter. The packaging may have some effect, as in glass is a better barrier to O2, etc. But there is air in the jar just the same.

I've been eating on a jar of Smucker's natural peanut butter that is almost one year old. It is fine and tastes good.

Looks and tasting fine means little.

Research shows the only ingredients in that brand as peanuts and salt. That means peanut oil which starts hitting worrisome rancidity levels in around a year if there are no preservatives or hydrogenation. Your nose and mouth cannot determine unsafe rancidity levels, regardless of you you want to believe.

It's time to finish that jar fast and replace it with a new one. If it typically takes you a year to knock out a single jar then you should consider the palm oil replacement brands, like Skippy Natural Spread. Leave the 100% peanut brands for those who knock out a jar in just a couple months. The Skippy Natural Spread using palm oil lasts several years and stores reasonably well if you want some emergency backstop.

What about peanut butter powder? I am not a big fan, but would the power keep longer?

Based on what? Your taste and smell? You aren't one of those one of every few million genetic freaks that can detect rancidity early.

Peanut oil without preservatives goes rancid in a year. So all 100% peanut butters are one year foods.

If you want longer lasting then you have to use a brand where they swap out oils that last longer or if they load up the preservatives.

As far as I'm concerned, if it takes you a year to finish off a jar then you aren't a purist fan. Just buy the safer stuff and quit posing like you can tell the difference. True fanatics can lick the empty jar clean in week or so, not dither over it for a year.

There are several kinds of powder. They have to be evaluated individually, much like jar brands all need individual scrutiny.

The right kinds of defatted powder can last quite a while because the remaining peanut oil is little in amount the rancidity factor isn't a real risk. You can mylar pack it as powder and later mix it with a long life oil, like palm or coconut.

Sure, if you find a brand that interests you then I'll research it online and opinionate on its potential lifespan.
