I’m a teen and I suspect that the corn oil we are using has gone bad. I can taste it and I can smell it while it’s cooking. How do I test it?

I’m the only one who seems to taste/smell it even though it smells rancid to me.

There isn't any way to specifically test oil to scientifically test oil at home. However, your nose and taste buds remain the best ways to detect when oil has gone- or is going - rancid. It takes on a strong odor and taste, both unpleasant. Some people are more sensitive to these gradual changes than others, which might be why you are the only one currently detecting it. The only thing you can do is suggest that it is time to replace the bottle with a fresh one. In case the reason for not replacing it is because it would waste the old bottle- there are ways to use that so it's not a wasted item. Old oil can be used combined with vinegar to clean, polish and lubricate wood items (not your cutting board though!) like chairs or furniture. It can also clean and polish metal or metal tools, or wicker baskets/furniture. Old vegetable oils can also be burned in a lamp just like lamp oil or kerosene. Drops of it will lubricate and silence squeeky hinges, too. Perhaps if you suggest alternative uses for it, rather than just tossing it- you can convince the family to replace that bottle with a fresh one. Oil usually lasts about a year, if tightly capped and stored dark and relatively cool. However, you can also increase the life of oil you will not use frequently- or if your kitchen is usually very warm- by putting it in the refrigerator. This won't keep it good forever, but it helps. It will thicken and cloud when cold, but should come back to a liquid state fairly quickly at room temperature when you need to use it.

Thank you for your response. I guess it does come down to me trying to convince my family. I have another question, I also taste the smallest resemblance of the rancid taste in other foods with no oil. Would that problem lie with me or with the the rancid oil taste lingering around?

Eeee, that IS a bit odd. I might mention this to your doctor during your next visit. There are certain conditions that can have an effect on your sense of taste and smell (which are actually linked together).

Yeah, I'm with Gammy on this one. If you find yourself experiencing a bad taste in your mouth with other foods, and the cause doesn't seem to be food related- it's time to have a professional look into things. The most common reason for taste changes are in the mouth- teeth and gums. So a visit to the dentist or your doctor might be in order.
