How Do You Understand The Meaning Of “Go Bad”?
“Go bad” should be understood as a process, not an outcome. Regardless of the type of food, there will be changes after a period of time depending on many factors.

How To Tell If Peanuts Go Bad? 3 Indicating Signs You Should Know
Although the signs that peanuts are spoiled are not so obvious compared to other root vegetables, if you are observant, you can still see if your peanuts are still fresh enough or not.
When it comes to peanuts that go bad, people usually don’t use the word “spoiled” but instead, use the word “rancid.” “Rancid” is defined as the term for foods with oxidized oils and fats.
In peanuts, there is a very high oil content. That’s why people use the word “rancid” to talk about peanuts when it goes bad. When this happens, it changes some of the peanut’s characteristics in terms of appearance, smell, and taste.
The peanut kernel is dry and shriveled. At the same time, the shell will become moldy and gradually turn gray. This happens because peanuts are placed in a humid environment, leading to mold.
If you smell the peanuts have a sour or strange smell like chemicals, this is a sign that the peanuts have gone rancid. The smell of peanuts should be the fatty smell of the oil inside, not the sour or musty smell.
If you’re still not sure about these two signs, give them a try. Rotten peanuts will have an unusually bitter and sour taste. Fresh peanuts should have a fatty taste. Just taste it, and you’ll instantly know if your peanuts are still good enough.
Don’t worry. Just trying a few peanuts won’t land you in the hospital. And if you still insist on eating all those rancid peanuts, I’m not sure.
