CANOLA OIL -- do you detect any "fishiness" or funky smell/taste? YEA OR NAY?

alkapal Oct 12, 2013 09:28 AM

Here is your chance to weigh in on this very important topic!

I'm asking purely about the aesthetics, not the politicization/science aspect (GMO type issues). So, please, if you have no problems with canola in the aesthetics sense, please do answer that you have no problem with the oil.

I'll answer first: YES, I do detect a funky "fishiness" to canola -- esp. when cooking with it.

    I haven't used Canola oil in years but I don't recall any fishiness. It was very neutral so I used for things like popcorn, cakes, etc.

      I used to and stopped using it. But then back in the spring I took an Asian dumpling class from Andrea Nguyen. She uses it and suggested keeping in the fridge. I do that and have had no problems since. So maybe it gets "funky" if left at room temp for 'too long.'

        No, never have.

              Yes, I do taste and smell a funkiness, so I never use canola oil.

                  Only when it's old, and then it can get really nasty. My late father-in-law didn't believe in refrigerating any kind of oil, and when we were clearing out the house an elderly jug of canola was one of the items I rescued. I use it only to put in the ant trap I made for my hummingbird feeder …

                  I don't use it at all anymore, with too many other, better choices for most uses. I did like it used 50-50 with olive oil when I made mayonnaise - the two oils together gave a pleasantly nutty taste.

                        Not uncooked, but if it overheats (not to its smoke point, even) I definitely think it tastes fishy. I wish I could throw out a degree number for when this happens, but there's a clear difference.

                                No, never. But I've heard this complained about so often out here that I suspect it's like how some people find that fresh cilantro tastes like soap, while most do not. A genetic predisposition.

                                  Maybe but. A few years ago I had some, that had been around a while, that had a somewhat fishy smell. Now that I keep it in the fridge it doesn't have that smell.

                                        Yes! For the longest time, I thought it was a problem with my cast iron until I read about the phenomenon here. I notice it when it first heats up, but not in the finished dish (note I do not profess to have the most discerning palate).

                                          This is from a Cooks Illustrated test:

                                          "Oddly enough, heat has the opposite effect on other oils. When subjected to high temperatures, the unsaturated fatty acids in canola oil break down and take on a subtle fishy taste; in soybean oils the effect is a slightly metallic cast. That said, while some tasters picked up on these off-flavors, these negatives did not markedly affect the oils’ overall rankings."

                                            I never did until I seasoned my Debuyer pan with about 1.5" of the stuff. Now I notice it every time I use it. The oil, not the pan.

                                                Yes. I detect fishiness, and never use it at home for this reason.

                                                  Yes. To me it tastes a little fishy and a little rancid.

                                                      And that's presumably not including the manifold comments on the previous canola threads to which I had linked.

                                                        I commented without voting - no funkiness for me.

                                                          It smells fishy when I cook with it, but I don't taste it in the finished food. But the smell is enough to put me off.

I think it was around the time I started reading other people with the same issue, so it might be the power of suggestion, but it's very noticeable to me now so I just don't use it.

                                                                    1. team_cake RE: alkapal Oct 16, 2013 01:31 PM

But, I no longer use canola for that method of cooking--to my nose, the smell will linger in the kitchen for days after frying.

                                                                      If I'm making a quick bread or similar recipe that calls for a 1/4 or 1/2 C. of oil, I'll use canola because I don't taste it in the final product AND I have a ginormous bottle of it to go through that I bought at Costco before I realized I had this aversion to canola's smell.

Ever since I switched to grapeseed and safflower for everyday use, I find many store made products with canola oil to have an off-flavor. This mostly applies to products where oil is a primary ingredient as in marinated tomatoes as opposed to where it's juts another ingredient among other strong flavored ingredients where I don't notice the taste. I remembered this thread as I tried to figure out why the marinated tomatoes and garlic I just bought just didn't seem to taste right.
