Talk:Soybean oil

Intro
This article needs a better introduction. Now that's it been split from soybean, the intro doesn't make much sense. I added a summary to soybean as required by WP:MOS. If you come up with a good summary intro, please update soybean accordingly. --UncleDouggie (talk) 09:31, 23 July 2009 (UTC)

I do think so and A table containing Nutritional point of view is very much needed for soybean oil title. —Preceding unsigned comment added by 202.70.74.163 (talk) 06:11, 11 June 2010 (UTC)

CNN just had a clown on complaining about how awful for your health soybean oil was and how much better sunflower oil is. Came here and saw big tables of multiple oils and multiple different oils and fats in them with quantities...and took away absolutely no idea as to what all these things mean. Stay away from saturated...I guess...but soybean seemed like one of the better oils. Needs some light discussion of each column.

History of soybean oil
Something on history would be good - don't have time to write it but I found this: http://www.soyinfocenter.com/HSS/soybean_crushing1.php

I was listening to someone on a podcast claim that seed oils are a new thing, but that link says there are mentions of soy oil from the 11th C in China. --Chriswaterguy talk 18:49, 27 March 2012 (UTC)

Too many decimals
I wonder why the values in the chart are given with three decimals. Variations between natural products will easily be much larger, so any decimals will just be misleading and make the chart too complex. --Sasper (talk) 10:31, 22 April 2012 (UTC) Totally agree, it should also be easier to find the unit (%) — Preceding unsigned comment added by 92.214.151.165 (talk) 18:38, 13 March 2015 (UTC)

Percy Lavon Julian trivia section and copyright violation
I removed an off-topic "Soy Sterols" trivia section about Percy Lavon Julian added on 21 April 2012 and 22 April 2012 by longtime disruptive IP-hopping anonymous editor 71.123.25.175 (aka 141.149.208.54 / 71.123.29.191 / 71.182.123.65 / 71.123.17.215 / 71.182.107.102 / 70.16.52.193 / 70.16.61.75 / 71.182.100.111 / 71.240.244.35 / 71.123.31.25 / 71.240.247.110 / 70.16.49.248 /  71.182.108.43 / 71.182.98.194 / 71.182.111.225) which included this WP:COPYVIO:"A one-pound package of progesterone synthesized from soybean stigmasterol was sent to the Upjohn company under armed guard and valued at close to $70,000.

Random Dangers-esque section in Applications/Food
It appears someone added a laundry list of possible risks from eating soybean oil to the section mentioned. However, I'm not too happy with the quality of the references provided; one is to a blog with no sources cited, the other is to an organization whose apparent stated purpose is cow's milk advocacy (which is only tangentially related to soybean oil by way of soy milk). It also looks like it may have been pasted in from someplace, given the haphazard formatting. Is it safe to remove this? -lee (talk) 03:09, 5 April 2013 (UTC)

Carcinogens
Report on Carcinogens, Twelfth Edition (2011) N‐Nitrosodi-n-butylamine has been measured in soybean oil at a concentration of 290 μg/kg, in cheese at 20 to 30 μg/kg, and in smoked or cured meats at up to 3.9 μg/kg. It has also been detected in tobacco smoke at a concentration of 3 ng per cigarette.

 * I'm having trouble finding the source of that 290ug/kg value. It was cited in IARC 1978, which cited Hedler's 1972 research "detection of n-nitroso compounds by gas chromatography", but I couldn't find that research online. Nevertheless, it's quite old 1972-ish, and there's a footnote in the IARC that says that this number was not confirmed by mass spectrometry. (Other values given alongside this 290ug/kg value were also disputed, for example 3 studies didn't detect any NDBA in cheese, contrary to the cited 20-30ug/kg value.) This 2015 report https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4609975 doesn't mention any NDBA in tofu, 0-0.48ug/kg in soy sauces and soybean pastes, which is strange since soybeans are 20% soybean oil - although this could be due to how soybean oil is processed. I wonder if anyone has any newer more reliable measurements of this, especially given the recent news of other potential problems with this oil, https://medicalxpress.com/news/2020-01-america-widely-consumed-oil-genetic.html which apparently do not apply to other soy products or other vegetable oils.

 * IMO, this is an unnecessary focus analogous to worrying about whether food contains harmful ultratrace elements: of course there is some presence in the food supply, but we trust the scientific process to prove if miniscule concentrations in food are harmful (they is no evidence they do). The Medicalxpress headline and article are examples of sensationalist and irresponsible twisted journalism, reporting of a university lab study presented as though it was conclusive about soy oil properties and human health. Nothing in that Medicalxpress article should be accepted as fact (except for the USDA data). As WP editors, we have to be skeptical of reports like this, and rather use high-quality WP:MEDREV sources or government agency reviews of safety in products like soy oil. In 2017, the US FDA approved a qualified health claim for products containing soy oil (discussed here), a determination that wouldn't have occurred if there were safety concerns, which have never been published by an expert authority. The European Food Safety Authority also has no concerns about soy oil safety, published here. This review of safety for soy oil use (compared to other plant oils) in products for IV nutritional infusions showed acceptable safety based on liver biomarker analyses, presented in the Discussion. --Zefr (talk) 16:11, 22 January 2020 (UTC)

Adulteration
Soybean oil is notable as an adulterant to substitute for more expensive oils (i.e. in peanut butter, olive oil, rapeseed oil, some chocolates, etc). Papers about inspection and detection methods also exist. Perhaps that a subsection about this would be interesting... — Paleo Neonate  – 14:28, 24 May 2018 (UTC)
