The article does not mention what the shelf life is if the container remains sealed.
Anyone know what the storage condition specifics are for the shelf-life statements?
Most PB containers I've encountered have a foil seal thats concave which indicates to me a vacuum, or at most a very minimal amount of oxygen in the lid area. I'll bet low temperature storage would be beneficial as well.
Also, I never buy "adulterated" PB ie: brands with added oil, sugar, stabilizers etc.
I only buy PB which is made from nuts and a little salt. Those are the only two ingredients on the label. Sure, you have to stir it but usually only once. And I never have to put it in the refrigerator either. It gets consumed within a couple of months after being opened.
After eating this kind of PB for years I got a dose of one of the kids' stuff brands and I almost vomited!
It tasted horrible with all the added sugar and oil. It literally tasted like greasy, peanut flavored candy.
I know I loved Jiff when I was a kid. "But when I became a man..."
Sorry, just a little legumor there.
In my opinion, that extra stuff is added for two reasons:
1. To make kids like it (brand loyalty conditioning)
2. To make it easy to spread (parental suffering reduction)
