My advice would be to keep that bet low, real low. lol Most commercial fish food is preserved with EQ, listing that fact is law in North America, but skirted around by many manufacturers. In Asia, there would be no such regulation in most countries. If not EQ, then for sure BHA, and or BHT. The more eco friendly alternatives would be too costly, for most Asian producers.
Yeah I'll admit without lab reports (impossible to get from any companies out this way lol) I did leave myself open on the EQ claim -- TBH I was in fact jumping to conclusions, perhaps based on my (limited) knowledge of 2 other brands out this way, both of whom purportedly don't use EQ, Hikari and Azoo.
I haven't been in touch with Hikari, but regarding Azoo's Ultra Fresh I did reach out to their office last year and directly asked if it contained EQ. Of course they could have been lying through their teeth like quite a few companies do -- and not only in Asia to be fair, even if more common here, but also right there in North America with Northfin too and their little EQ PR nightmare lol.
But here was Azoo's reply:
"We don’t add Ethoxyquin preservative in our Ultra Fresh series (or other AZOO fish foods) since we have dry our food down to min. 3% water to keep the food not get moldy."
Now I'm not sure if that's true, I'm not sure if it's even logical, and I'm not sure if like you say they might use some other preservative like BHA or BHT -- but yes I perhaps naively believed them and extended it also to Sianlon given they only target more local markets and don't have to ship half way around the world -- maybe they don't
need EQ was my assumption. But sure, I reckon they would have to use
something as a preservative.
But just for the sake of argument let's say Sialon contained BHA or BHT instead of EQ. Not great maybe, and yeah I wish they used Naturox, but it would nonetheless lead me to ask: which has more potential negative health consquences, EQ or BHA/BHT?
Personally, I'd again bet (lol, double or nothing?) that EQ is the worst of the 3 (in fact BHA & BHT curiously have the potential for both bad and beneficial effects according to this study):
http://www.iffo.net/system/files/Uses of ethoxyquin and alternatives 1993-7.pdf, something I kind of doubt can be said about EQ.
Likewise it's my understanding that at least BHA & BHT are GRAS (generally accepted as safe), and approved for use in human foods/products in US/many countries (even if there are quite a few studies that question this is good or bad) -- while EQ 100% for sure is not allowed as a direct additive for human products, only animal feed, etc. Sure people and fish aren't the same, but I think I'll take the BHA/BHT thanks
That said, I have absolutely no idea if Sialon contains EQ, BHA, BHT or something else, would love to see a lab report but that's wishful thinking.
But what about the king of fish food (popularity wise) Hikari? Are they skirting around such laws as you mention? What are they using instead of EQ as a preservative? Also I wonder if they use different ingredients between their Asian and North American/European products, or are they exactly the same?
And getting back to Sianlon Arowana pellets and my (possibly) lost wager: EQ, BHA & BHT are used as stabilizers, or more specifically as antioxidants, right? (so that fish food doesn't get moldy/go bad too fast, and container ships don't blow up en route to manufacturers).
I could be waaay off base, but could the fungal polysaccharides -- proven natural antioxidants -- that Sianlon contains (and coincidentally Azoo Ultra-Fresh also btw),
possibly be acting in this capacity (so no need for EQ/BHA/BHT), or are we talking about 2 different processes?
I personally don't have a clue, just throwing an idea on the table. But if this were correct, perhaps some of these Asian fish food companies are more progressive than we often them give them credit for.
Or they could all just be a bunch of corporate crooks lol, who don't care if my Aros live 2 years or 20, I really don't know for sure. That said they certainly they do operate with much less governmental control and health/safety oversight compared to Western countries, nobody can argue against this. I hope some day, over time, this will change in Asia/SEA.
