Does ethoxyquin (E) dissipate when heated? I ask this question because I know alot of YTer's have tried to stay away from food that contain E but it seems that one has to do alot of digging to uncover the truth about E and foods that contain it. Below is a website by Iams that states that "E remains stable at high temperatures". While Natural Balance claims that "by the law of the US Coast Guard all fish meal transported must contain E" but this is okay because "once it is heated during processing it dissipates," so which is it? Understanding Ethoxyquin |
That's a bit scary that the government mandates that specific compound... I recently switched over to a Canadian brand of food-- hopefully there's not a similar law in Canada. :( As far as thermal stability of ethoxyquin, I tried poking around a little and found an abstract of an article that claims that its effect as an antioxidant decreased by 60% at 150 degrees Celsius, but I couldn't find anything that suggested how much heat for how long would be needed to "burn off" ethoxyquin entirely. Any chemists in the crowd? |
It is so irritating that you almost need a degree in chemistry or food science to figure out if you are poisoning your dog or now. :( I have no answer but would really like to know because I didn't know Natural balance contained ethoxyquin at all. Because dog food manufacturers who use ethoxyquin as a preservative add it before cooking (I would guess?), it would have to stay stable at the temp they use to be effective...:confused: |

The problem is both companies probably have just enough scientific data to back up their particular findings , which just adds to the confusion. How are we to really suppose to know which study (if they even conducted a full study) is correct and which results are skewed slightly to favor the companies philosophy. So frustrating :mad:. |
Somebody could contact Monsanto, the producer of ethoxyqin, and ask. |

Just to be sure I email Natural Balance and received the exact same email. That is exactly my thinking, why use it if it breaks down during heating? The whole purpose of its existence as a preservative no longer matters if it no longer exists after being heated. PennysMum: I too am feeding a Canadian brand right now (Acana) and I have emailed them about E as well. On their food they say they do not use E, but that does not mean their suppliers do not use it. It is perfectly legal to put the statement on the bag as long as they do not personally add it during processing. I got an automated email saying they would get back to me with in 10 days. I will be looking into this matter more thoroughly. |

That is my concern with all fish kibbles. A lot of fish is preserved with it. Come to think of it, Ellie eats whitefish. It is preservative free but that doesn't mean that it wasn't used when they were caught.:mad: I'm so tired of all of this. |
Here is information about people who experienced Gulf War Syndrome symptoms after consuming fish meal with E. http://www.ask.com/bar?q=History+of+...2F95071985.txt Article from 1197 about ethoxyquin and talks about Canadian pet food. CBC Marketplace: 30th Anniversary |

Dogears: I'd be curious to hear Acana's response if you get one; that's the brand I've been feeding my dog too. I'm hopeful that the food may prove to be all right, especially since it is labeled for sale in the EU, and food standards in Europe tend to be much higher over all than they are here. |
Interesting. This is why I've always liked Orijen's 6-Fish, as far as kibbles go. They claim to be ethoxyquin free: Q: ETHOXYQUIN: Does ORIJEN contain ethoxyquin? A: No. ORIJEN fish meats arrive FRESH; which means they are never frozen and have no preservatives what-so-ever. We work directly with our fish meal suppliers and pay them a premium to have ORIJEN fish meals preserved naturally with Vitamin E, Citric acid and Rosemary extract instead of the commonly used ethoxyquin preservative. |
On the website Champion Petfoods | ACANA | Our Focus is Fresh in the descriptions of the fish they clearly state that the Salmon, Flounder, and Herring are delivered fresh never frozen and w/o preservatives. But the walleye, whitefish, and pike do not say they are delivered fresh w/o preservatives. When I hear back from Acana I will post what they have to say about this. FYI: The Acana Pacifica, we can safely conclude that it DOES NOT contain ethoxyquin because it contains only salmon, flounder, and herring. |
