Pyrotechnic salad
I don't usually have a question that is appropriate to
rec.food.cooking, rec.woodworking, rec.pyrotechnic and sci.med.nutrition. But I've been wondering about flaming salad. I've been researching flax seed oil. It's great nutrition; it's very high in omega-3 unsaturated fats, which are the very good kind. But it's hard to work with; it oxidizes - goes rancid - very quickly. People in the know say that the fresh oil, and oil that has been well tended, tastes delicous. But that a lot of the flax seed oil you buy has gone rancid already. Along the way I found out that flax seed oil == linseed oil. Wow, I said. They use that for drying paint and finishing furniture. When I lived in Atlanta, they were doing furniture-finishing at the the house next door to me. It burned down. The cause was linseed oil-soaked rags, improperly stored. See, this stuff oxidizes so fast it actually can ignite. Any rags that have linseed oil on them should be placed in an old paint can, with a metal lid tightly closed. So I've been wondering - if I use flax seed oil as a healthy salad dressing, can I get it to burst into flames at the table? I realize that this may alter the taste some, and the nutrient balance. But it sure would an attention-grabber at the next church potluck. What nontoxic thing could I do to speed up the ignition and make it more certain? David Throop |

Even so, it will not oxidize quickly enough in air to ignite a salad because the heat is not trapped (by the insulating rags). So perhaps you could add something like manganese heptoxide to act as an oxidizer *and* catalyst. I can't find anything about its acute toxicity. Bob |

Boiled linseed oil uses cobalt (which is a lousy drier) because the alternatives are either lead, or a mixture or lead and manganese compounds. The cobalt is there for "safety" ! I can't imagine eating anything made from linseed oil. The stuff is horrible, even when freshly pressed. The seeds alone aren't too bad, but concentrated into the oil their taste is just overpowering. -- Smert' spamionam |

Yup. It's very nutritious. Almost as rich in omega 3's as hempseed oil or
salmon oil. That said, I think you'd be hard pressed to get an edible auto-ignition. You might try fueling floating, oil-fueled candle at a dinner with said oil to make a point if you care to. The company for which I work has done much research into these oils. We recommend salmon oil for nutritional purposes. We do not manufacture these oils, but only provide them to patients. There is on the horizon, vegetable oil made from genetically engineered plants that will have a more favorable omega-3 / omega-6 balance. These are probably a few years off, though. If you're not a strict vegetarian, fish oil is still your best bet. One decent brand is Tyler "Eskimo 3." Another that is usually good, but has had some reports of rancidness is Coromega. For vegetarians, hempseed and flax oil are decent (though not up to fish oil standards). Don't know about flax oil, but hemp seed oil tastes like crap. Too bad, since it is at present the best source of vegetarian omega 3 oil. One can get them encapsulated. Remember to put them in the fridge after opening to retard oxidation. "David R.

Great - I was expecting something like that but hadn't heard anything. I have been trying to find an oil that was high in mono-unsturated omega-3. Olive oil is great as far as it goes, but it's mostly Omega 6. I'm not vegetarian and I eat lots of oily fish. Why swallow caps when I can have sardines for breakfast?

It works well for wine; thought I'd try it for the oils too. Plus the refrigeration. David Throop Followups set to sci.health.nutrition, where this seems to be heading. |

Grind them up in the coffee grinder as needed, otherwise they do degrade rather quickly. Mostly they get used to make Bran/Flax muffins. These are actually very tasty and we make ours with Almond Flour and Sugar Twin, so they're low carb. The ground seeds also make an "edible" porridge substitute, which is very healthy. Also they make a good coating for oven fried chicken (if you can stand the smell), but the heat destroys the Omega 3 I believe. > My sister bought me a device for keeping wine fresh - a hand-operated > pump and a set of rubber stoppers through which you can pull a vacuum. > It works well for wine; thought I'd try it for the oils too.

Hard to make a call on this. Personally I use one oif the highly refined
brands -- Eskimo 3. There is a rumor about that my company may be switching to another brand, but I don't think purity is the deciding factor. I doubt that for a man of middle age or later that heavy metal contamination would be much of an issue -- not nearly as much as risk of coronary disease from dyslipidemia. This would be an interesting project for someone with a heavy duty chromatogrphy set up and a big government grant: assay various oils being sold for purity, conformance to contents as stated on label, etc. Since these are natural products, by-products of commercial fisheries and so forth, there might well be great variation among different batches depending on ultimate source, season of year, processing, and so forth. Me, I take my chances on the metals on the bet that I might stave off that coronary a while longer. "Rick Cook" > wrote in message ... > > > W Klofkorn wrote: > >> Yup. It's very nutritious.

It > does take longer to dry, but hey, I live in Arizona! Truly "raw" linseed oil will never completely dry, because of the fats and fatty acids in it. If you want true boiled linseed oil, cook your own. It involves heating the raw oil in a water bath (double boiler)for several hours, until all the fats agglomerate and float to the top. Then it's skimmed, like a greasy soup, and the clear, fat-free oil is decanted. Commercial "boiled" oil has those drying additives primarily to force the fats to cure like varnishes. But oil with dryers in it never performs like real boiled oil when doing a French polish on top of shellac. LLoyd |

It's entirely different to the boiled-oil processes of traditional cabinetry. They're cooked at a higher temperature and they involve the addition of a metal salt; lead or manganese. >But oil with dryers in it never performs like >real boiled oil when doing a French polish on top of shellac.

"Andy Dingley" > wrote in message ... > What on earth is a drying oil doing mixed in with French polish ? Brain-finger-infarction. Not mixed in... The French polish is done with the shellac, but it doesn't hold very well in the presence of moisture. A very, very thin rub-out with linseed oil and super-fine wool over the shellac doesn't detract at all from the appearance, but protects better. You have to wool it once more after drying to kill the gloss. Done with chemically "boiled" oils, the coating never really dries. With the real stuff, it's totally dry and "micro-varnished" overnight. LLoyd |

I don't hold with this whole idea of using linseed oil in French polishing at all. I use mineral oil, because I _know_ it's not going to cure and will come off easily once I've finished. > The French polish is done with the shellac, but it doesn't hold very well >in the presence of moisture. A very, very thin rub-out with linseed oil and >super-fine wool over the shellac doesn't detract at all from the appearance, >but protects better. Interesting idea - can't say I've tried it. I don't French polish much. Most of my stuff is shellac over oil (tung) because I don't want such a "formal" finish as a high-gloss French polish. I must give this a go, because I really can't imagine it working to deliver what I expect as French polish. I'm working on a couple of cremation urns at the moment; sarcophagus "tea caddy" style, one in walnut, one in mahogany. I might give it a try. >Done with chemically "boiled" oils, the coating never really dries. With >the real stuff, it's totally dry and "micro-varnished" overnight. I still don't agree that this is is "the real stuff". What's "chemically boiled" oil ? To my mind, the real stuff is hot-boiled with lead or manganese salts, and neutralised with limestone chips. This is still a process involving the addition of chemistry, but it's the classic recipes for cabinetry. Do you have any references for low-temperature purely heat-polymeriseed oils ? I'm interested in collecting these. -- Smert' spamionam |
