This thread is hasn't been used in awhile but I am just now reading it. I've always gone along with FAN's statement that refined peanut oil is safe to eat. We've been living life accordingly for the past three years. My daughter has probably eaten at chick-fil-about twenty times without a reaction. She has had several airborne peanut reactions and reactions to foods with peanut flour (her preschool inadvertantly fed her a cheap assorted cookie without reading the label.) The website: [url="http://www.anapylaxis.org"]http://www.anapylaxis.org[/url] agrees that eating peanut oil (refined) is safe. The only way to show that it is 100% safe is to test every peanut allergic individual. I feel comfortable going by that advice. Does anyone agree-or should I rethink my thinking? A mom from Paducah

My allergist informed me that peanut oil (hot-pressed) has not caused any allergic reactions in peanut allergic persons. However, many foreign countries produce cold-pressed peanut oil and companies in the U.S. may purchase it. Cold-pressed peanut oil could cause a reaction because the peanut proteins are not heated and broken down during manufacturing. There could be enough of the protein to cause a reaction. There is really no way to easily tell if a food manufacturer is using hot or cold-pressed peanut oil so I avoid peanut oil products for this reason.

Does heat really destry the peanut proteins and make them non-allergic/ If this where they case them roasted peanuts would be non-allergic?

No, heat does not break down the protein in peanut. This protein is one of THE most stable of all proteins which is why it is such a problem. I don't know why "hot-pressed" peanut oil is okay. I'm not quite sure what "hot-pressed" means except that it is some type of manufacturing process to extract the oil. Maybe it uses heats higher than are normally achieved in normal manufacturing or food preparation. Maybe we need to do more research on this peanut oil issue.

I know that this is an older thread but I did find a study that discusses the use of peanut oil and testing in allergic people
It states
"Randomised, double blind, crossover challenge study of allergenicity of peanut oils in subjects allergic to peanuts
Jonathan O'B Hourihane, clinical research fellow,a
Simon J Bedwani, medical student,a
Taraneh P Dean, senior research fellow,a John O Warner, professor a
a University Department of Child Health Mailpoint 803 Southampton General Hospital Southampton SO16 6YD
Correspondence and reprint requests to: Dr Hourihane
Objective: To determine the in vivo allergenicity of two grades of peanut oil for a large group of subjects with proved allergy to peanuts.
Design: Double blind, crossover food challenge with crude peanut oil and refined peanut oil.
Setting: Dedicated clinical investigation unit in a university hospital.
Subjects: 60 subjects allergic to peanuts; allergy was confirmed by challenge tests.
Outcome measures: Allergic reaction to the tested peanut oils
Results: None of the 60 subjects reacted to the refined oil; six (10%) reacted to the crude oil. Supervised peanut challenge caused considerably less severe reactions than subjects had reported previously.
Conclusions: Crude peanut oil caused allergic reactions in 10% of allergic subjects studied and should continue to be avoided. Refined peanut oil did not pose a risk to any of the subjects. It would be reasonable to recommend a change in labelling to distinguish refined from crude peanut oil.
Key messages
Peanut (groundnut) allergy is the most common cause of deaths related to food allergy. Peanut oil is often suspected of causing reactions to meals in which a more obvious source of peanut cannot be found
Refined peanut oil is odourless and flavourless and is commonly used in catering. Crude peanut oil, which is known to contain considerable amounts of protein is used only rarely, when a peanut flavour is deliberately required
In vivo challenges of 60 subjects with proved peanut allergy showed no reaction to refined peanut oil, but six (10%) reacted to the crude peanut oil
If refined peanut oil is used properly and is not reused after cooking peanuts, it seems to be safe for most people with peanut allergy; crude oil represents a risk
The confusing use of the term groundnut oil should be stopped, and food labelling should distinguish between refined and crude oils"
Hope this clarifies a bit ...

Hi Mary! Thought you might be interested in this site. They had an article on peanut oil you may have already seen. (You're very well read.) [url="http://www.anaphylaxis.org.uk/whom.html"]http://www.anaphylaxis.org.uk/whom.html[/url]
