And just to be clear, NLS doesn't add preservative of any kind to their formulas, they never have. The Naturox will be used by their suppliers of fish, and squid. The krill will be shipped preservative free. The following was posted on Kmuda's forum by a rep that works for that company.
"Full Disclosure, I work with the largest producer of krill-derived products in the world. At a recent Trade Show I was asked to chime in on the Ethoxyquin issue and whether or not there is actually krill meal available that is properly preservative free.
I can say, definitively, that there is krill meal produced that is preservative-free. The issue with preservatives in fish meal has most to do with the cubic volume of the product being shipped. Fish meal, and krill meal, are highly oxididizable and therefore dangerous to be shipping in an enclosed space like the hold of a freighter. Ethoxyquin is a supremely effective anti-oxidant and well indicated in feeds destined for fish.
Krill Meal behaves differently than fish meal in that the fat is not easily separated from the protein...where fish meal can hover at 6% most krill meal has fat levels over 25%. This is due to the peculiar nature of the Omega3's in krill. While there are Ethoxyquin alternatives, none immediately presents as effective...particular for krill meal. It is likely that given the regulatory trend, producers will move to a blend of some sort or, ideally,utilize larger scale vacuum packers with nitrogen flushing. This however, is very, very expensive.
Our company has been producing a preservative-free krill meal for some time. This product is packaged in 25kg bags which are vacuum packed...the naturally occuring Astaxanthin in the meal provides stability for up to 2 years. This particular meal has undergone an additional sieving process to reduce the shell volume (and thus the flouride levels) making it suitable for mammalian diets.
I am not aware of any other krill producer who offers non-ethoxyquin preserved product in meal form. The only exception being product that has been deep frozen prepped for oil extraction. This type of meal is very, very expensive given the front-loaded cost of said preservation. This is not to say that there aren't some kg's of natural krill meal out there. However, given that the second biggest producer has just gone bankrupt (Olympic/Rimfrost) and two of the other 9 boats previously fishing for Antarctic Krill have been docked, it is unlikely.
For reference, preservative-free krill meal is roughly 2x the cost of ethoxyquin treated product."
Hope that helps.
