Talk:Rapeseed

Missing vital information
I can't believe the awful smell of rapeseed fields isn't mentioned in the entire article. It stinks, I grew up in an area where it was grown. Big smelly yellow fields. Rapes your nostrils.

"Now known as canola"?
Not here in the United Kingdom, it isn't — I for one have only ever seen it as "rapeseed oil". I suspect that whoever wrote this section, or the section title at any rate, is suffering the "we are the world syndrome" — the conviction that the world map consists of the USA and "here be dragons". — 188.28.54.179 (talk) 20:08, 26 April 2012 (UTC)
 * I've never before heard the term "rapeseed". Every store around me has CANOLA oil and I live in Philadelphia, only 1.5 hours away from NYC.74.109.49.183 (talk) —Preceding undated comment added 16:52, 20 April 2013 (UTC)


 * hey, don't pin this one on us yanks -- the "can" in canola is for CANADA!!!! 66.105.218.9 (talk) 10:17, 29 September 2012 (UTC)


 * Agreed. Have a go at editing Wikipedia yourself to transfer references of Canola to the article on Canola. This would help to counter systemic bias--Aspro (talk) 16:46, 28 April 2012 (UTC)

Ive never heard of it being called rapeseed oil... I suspect our OP is suffering from the conviction that the world is homogeneous outside the US. PrimalBlueWolf (talk) 09:11, 9 August 2016 (UTC)

GMO?
RE Gmo. If anybody asks if the old type rapeseed with quite a some erucid acid was converted by GMO into modern rapeseed / canola, with just minute traces of erucid acid. Nay, this was done by strict, systematic and controlled selection, long before any GMO was thought off... So it was done in Sweden, and I bet so it was done in USA / Canada too.../StefanZ, Sweden90.231.255.39 (talk) 13:05, 31 May 2021 (UTC)/StefanZ

Is the GMO controversy section really relevant on this page? There is a more level-headed paragraph on the Canola page. «ɧʒχχ (tOk•k«n'trIb) » 16:38, 14 June 2013 (UTC)

Merge with Canola
There is much overlap with the Canola page. I propose Canola deal with the oil and Rapeseed with the plant. — Preceding unsigned comment added by 108.213.76.24 (talk) 05:06, 15 October 2013 (UTC)

Rape reference
Not sure why only one of the names listed in the intro needs a reference, but how is the Encyclopedia Brittanica? http://www.britannica.com/EBchecked/topic/491375/rape 122.106.178.25 (talk) 07:24, 24 November 2013 (UTC)
 * Thanks. You're right the other names need to have citations. Please see the new Common names section I added to the article. Hamamelis (talk) 17:18, 25 November 2013 (UTC)

This reads like a one-sided ad
Excuse me, but this entire article seems to be a one-sided ad for the benefits of Canola oil. It may well as be directly from the financial supporters that tend to turn a blind eye to any problems. Notice how many of the references are from such dubious mono-sources in Canada? A balanced article would include the multitudes of problems associated with the direct human consumption of this product.

It would also include the controversy on how it became elevated to "safe food" status so quickly, with big cash payment to the FDA a waiver on human testing being needed to do so. That's the real reason for the difference in the names: Rapeseed oil (not the greens) was known to be toxic for animal or human consumption for many decades before WWII, and so the term Rapeseed use in the USA is discouraged by the Federal Government, AG universities such as Purdue, and also in the Farm trade magazines, where it is called "oilseed turnip".

From my personal experience, ANY trans-fat acid derived from this plant contains long-term health detriments that are not mentioned, or if brought to light, squashed by paid promoters of this product. 2% is not a low enough level to suit me. How about none? That sounds a lot better. I have eliminated CANOLA from my diet for the last year, and with it I eliminated: Chronic diarrhea, frequent low-level nausea, night-time stomach upset/heartburn, and excessive gas. Now I learn that it can inflame circulatory and cardiac tissues, one of the few negative effects listed in this article, I am even more glad I have removed it from my diet. Canola seems to me to be little better than smoking cigarettes: slow poison to a healthy person, somewhat quicker for a sick or older one.

One other controversy: the forced placement of Canola as a suitable substitute for olive oil. It simply is not. The over all chemical profile of olive oil can be described as anti-inflammatory. The overall chemical profile of Canola is pro-inflammatory. Big difference on long-term health effects. DHS — Preceding unsigned comment added by 75.149.77.237 (talk) 13:54, 8 July 2014 (UTC)

vegetable or oil use?
The opening sentence is quite long and ends with "consumed in China and Southern Africa as a vegetable." As I read it I say to myself "I guess it is most important as a Chinese vegetable, which is why two Chinese names are given, and no African or any other name. Then the last line of the lede says "B. napus is cultivated mainly for its oil-rich seed, the third-largest source of vegetable oil in the world." Now I say to myself "that's certainly what I'm familiar with."  I think the lede should just give some basic intro material to the article.  The article is certainly about the oilseed perspective.  So I recommend that the mention of Chinese names and its consumption as a vegetable be moved to a separate section of the article on "Rapeseed plant as a vegetable" or something like that.  --Richardson mcphillips (talk) 14:11, 24 May 2015 (UTC)

Name change to canola oil.
The section "cultivation and uses" mentions that the name was changed because of the resemblance to "rape". This is not true. The product and name, "rapeseed oil", is still used, but it's toxic and not suitable for human consumption. Canola oil is edible variant.

 * Edible rapeseed is usually known as "cold-pressed rapeseed oil" in the UK. The name Canola is little used. Both articles seem to need attention by an expert. --Mervyn (talk) 10:55, 17 July 2016 (UTC)


 * Just removed non verified connotations to human rape in both articles. The reference given did not mention this linguistic link.--Aspro (talk) 15:40, 18 July 2016 (UTC)

"seed press-cake"
We seem to be on the same wavelength regarding the article Rapeseed. I see where your coming from with Pomace but that is nearly always considered the residue from fruit. Therefore, I add this: A farmer or farm manager tends to like to keep things simple and may refer to "seed press-cake" as simply cattle cake or meal or what ever phrase suffices in polite conversations down at the Pub. When bought in (to feed livestock (cattle, sheep, pigs etc)) this meal (from what ever source) may have have additives like molasses and vitamins added to it  suit the livestock that it is being feed to. So, I think meal is better than  "seed press-cake" which gets processed before the cattle or pigs get to eat it. What we really need, is a farm manager that has gone to agricultural collage (and has enough degrees in this subject to get a job as a greenhouse thermometer) to comment. --Aspro (talk) 15:33, 20 July 2016 (UTC)
 * In the interests of helping the WP consumer, we should link to existing articles which in this case is apparently best-suited to press cake, also supported by WP:SECONDARY references where found, such as here for crushed seeds. Press cake from seeds is not always destined for animal feed, but is also a source of dietary fiber, protein and micronutrients for manufacturing human foods and supplements. --Zefr (talk) 15:50, 20 July 2016 (UTC)


 * Good point but I think it comes down to the vernacular. Farmers refer to it as rapeseed meal because it is meal that comes from processed rapeseed. Pressed cake is more of an industrial nomenclature and thus the  average reader my confuse  pressed cake from sunflowers, with  pressed cake from rapeseed and competently lose the connection with meal.  Never seen humans eating pressed cake ! Comes in large diameter short lengths like this Oil press cake. Now-days gets turned into meal instead. Rapeseed meal.  'Meal' is what ends up in your snack- bars not lumps of cake but I am more than willing for someone with an agricultural and live-stock  degree to correct me.--Aspro (talk) 17:43, 20 August 2016 (UTC)

Rapeseed-Mustard cultivation in India- An Overview
"Rapeseed oil takes between 135 and 150 days to mature, with some varieties only taking 110."Cited PDF This sentence caught my eye because it doesn't make sense, but clicking through to the source it seems to be an overview of "rapeseed mustard", not specifically brassica napus. The section this info appears in starts off specifically mentioning brassica juncea so I'm not sure the information is actually relevant. It also refers to the crop, not the oil. I think this source has potential uses, but not this bit and not here like this. I think I've just convinced myself to delete the line, but I'll leave this here in case anyone has the time to read the source and put in something better. Dichohecho (talk) 14:00, 15 October 2018 (UTC)

ETA: I deleted both uses of the source. Brassica_juncea oil-seed mustard is included in canola along with brassica napus but is definitely not the same thing. I suspect this is where some of the confusion has arisen. There are some references to brassica napus in the source but the specific parts used here (before I deleted them) referred to all of the looser group of brassicas used for oil.

Rapeseed oil -> Canola oil instead?
I only just learnt that 'that North American canola thing' is rapeseed oil - or at least *a* rapeseed oil, still not sure if there's a distinction and if there is that I understand it. But perhaps 'rapeseed oil' should redirect to 'canola oil' rather than to 'rapeseed'? If canola oil is a subset of rapeseed oils, then perhaps that page should be renamed 'rapeseed oil', with a section or whatever on what makes such an oil canola or not.

Rape Link
What is the reason for the link of the word "rape" in this article to the seperate article on (sexual assault) rape. Each article gives an etymology and the word rape appears to derive from two different Latin words, so there isn't even a "language link". 2A00:23C7:5992:4A00:6917:1DF2:E0FC:1066 (talk) 07:30, 21 May 2022 (UTC)

Brassica napus should not redirect to Rapeseed
Rapeseed and Canola are only a few of the many varieties or cultivars of Brassica napus. Brassica napus deserves its own page about the whole species, similar to the pages on Brassica oleracea and Brassica juncea. I remember that Brassica napus used to have its own page instead of redirecting to Rapeseed. What happened to that page? Bengtang (talk) 20:25, 4 September 2022 (UTC)


 * I strongly second that. This page is like as if Brassica oleracea should redirect to Cabbage, ignoring Kale, Cauliflower and Brussel sprouts.
 * Now for instance the page on Rutabaga is orphaned. We need a page on the plant, and one each on the most important cultivars, just like the other Brassicas, and other cultural plants in Wikipedia for that matter. jax (talk) 07:34, 25 June 2023 (UTC)
