Not sure how any of the fish food manufacturers get away from any preservative of krill. You literally have hours before the krill is not useable.
It's processed immediately on board their ships. As explained by the rep, vacuum packed with nitrogen, resulting in being naturally preserved.
If the posting of the person who worked for a krill manufacturer is true, then using anything but ethoxyquin would easily raise the price of krill by double. The fish food manufacturers would then increase their prices to be on a higher end than others. I haven't seen much of a difference in price between NF, Tropical, or NLS.
It's true, after initially reading his comment I personally verified the source of that comment. Just using common sense, does it sound like that was someone talking out of their arse? I certainly wouldn't think so. His info was all spot on, from only someone that works within the biz would know.
As far as cost, that remains to be seen, I think you are forgetting that NLS is just switching over to Naturox. The plan was for Sept, but then a hurricane of epic proportions hit the coast of Florida which impacted everyone in the line of fire. New Life is based in Homestead FL.
Secondly, unlike many food vendors New Life owns their own land, equipment, etc, and manufactures their own food on site. By removing the middle man they are able to better control the entire manufacturing process, including costs of raw ingredients. Is the switch to non EQ krill going to increase production costs, absolutely, but from what I was told by the owner they were going to keep retail costs as is. That may change, I honestly have no idea. The owner of New Life is close to 80 yrs of age, not everything is about $$$.
