Over in What Have You Done This Week thread, we ran into the topic of rancid oils. Both by themselves or in things like peanut butter or even the whole ground flours and brown rice. Yep, it's the oils in those products that make them 'go bad' before polished white rice, etc.


Here are some links I found in a quick search. [I can't verify the science stated in any of these sites :shrug: ]

Use for old oil?.... Has anyone tried this with old french fry oil??????? If rancid oil - would it stink? :unsure:

Oil

Now you may be thinking, burning vegetable oil must be very smelly. Some oil may be, but olive oil burns very clean and without odour. Smoking oil smells unpleasant, but burning oil does not. So forget the stench of a smoking frying pan. However, even the smellier types of oils can be used economically outdoors. Perhaps you have a bottle of forgotten salad oil at the back of the cupboard. Here is some use for it. Or how do you get rid of the deep frying fat after making a few batches of chips (French fries)? Light your porch, patio or garden path. You could even collect waste oil from fast food joints. Strain it and use it for your lantern. You could also add a few drops of essential oil for a scented light. The volatile oil will evaporate easily with the nearby heat, before the flame can actually burn it.




ANYway...let's be careful of burning oil...of any kind.... :grouphug:

After reading the bit about olive oil, I am really more happy than ever with my lard! LOL

I've never had any luck at all burning olive or other oil in a lamp. My favorite use is to have it handy to pour over the wood in the woodstove on those mornings that I cannot get the stinking thing to catch. (Don't have a woodstove at the moment, but plan to if I EVER move back to someplace cooler.) There are still fast food joints that will let you have 5 gallon jugs of rancid, dirty oil and that is perfect for your woodstove. Don't have to do anything at all to it.


Weevils in grain will make it rancid real fast. All grain has weevil eggs. That is why you need to freeze or seal in an oxygen depleted bag right away. I've even found dead weevils in plastic bags of mixes from the grocery. The eggs survived all the milling and mixing and hatched inside the bags. Eventually they deplete the O2 and die, but then you have bugs in your food and you can usually smell them.

If you are unsure the age of grain and are getting ready to put it in mylar and seal it, take about 1 cup of the grain from the top of the bag (bugs tend to like the top better than the bottom) and pour into a good size bowlful of water. If you see bugs on the top, you will probably either want to return the grain to the store or use for animal feed. Don't bother to put it in buckets or mylar, it won't improve the situation.

If you have a bag of buggy grain and no other choice but to eat that grain, you can improve the situation by washing it. Pour some into a large bucket of water and vigorously rub the grains between your hands. Pour off the water and keep repeating till the water is clear. This will remove most of the bugs and the trash they left. You won't have as much grain but at least it will be more edible.

Rice will go rancid too, but I've found that washing it multiple times till the water is clear will remove the rancidity. It mostly seems to be in the powder coating the rice. Yes, that removes a few vitamins, but that isn't a tragedy if you have another source of vitamins. It seems to me that most rice is rancid when I buy it so I wash it all. I'm not a big fan of rice, but it is one thing daughter can have on her diet.

I just pulled some whole wheat flour out of the freezer and was planning on making some bread with it. Then I looked at the date, June 2008! lol It doesn't smell bad, i would flour smell bad if the oils have gone rancid? It's been in the freezer the whole time.

The flour is fine. Go ahead and use it. It would smell off.

I hear that Crisco shortening is the best to store as far as it not getting rancid. Not that healthy, maybe, but would be better than nothing. I got powdered butter. Hope it works OK.

If I had another freezer I would freeze oils and more butter.
I can, you can, too !

Violet, do you have any info on how toxic....what kind of toxic...the rancid oils are?

CGA.... LOL I thot I was the only one who couldn't get the olive oil ....or other oils to light in most holders. Regular old-fashioned oil lamps with lamp oil or kerosene are fine. But the decorative ones with the round wick.... :shrug: ..they light and go right out.


MtRider [..and I still keep a couple of cute, artsy ones...hoping someday, I can figure how to keep them lit... :rolleyes: ]

Thanks, Mt Rider!
