Storage of flake foods?

I think we need to distinguish between opened and unopened food.

Properly packed, unopened food stored in a cool place, would probably be fine through its expiration date, and perhaps quite some time beyond.

However, I believe, once you open any food the timer starts immediately. You've exposed the food to air and moisture and the food will degrade. In my experience, it becomes less palatable to the fish and I believe nutrients are lost.

When Doug Sweet, the former curator of the Belle Isle Zoo spoke at a Classic a few years back, he said that 50% of nutrients are lost within one week of opening a package food.

In the short term, I don't think that's too much of an issue since the manufacturers add an abundance of vitamins. Some manufacturers also include chemicals which help prevent oxidation.

So, to be on the safe side . . .

I buy food in a bulk and keep it in the freezer. I only take out enough to feed my fish for about a week. I use screw-top Rubbermaid containers for the food and also add a desiccant pack to keep it nice and dry.

Desiccant is often shipped inside of fish foods (e.g. Dainichi) to absorb moisture.

And there you have it from the man himself! Keep it dry and cool and it will last for as long as you need it.

Pablo is the expert, at least I would hope so considering he designed and created NLS

If all else fails contact the experts I guess:

Donna Landry Office Manager at Headquarters of NLS asked their folks and the over all opinion is-

"Using dry and cool storage NLS flakes will remain completely stable in regards to product nutrition
for 3+ years. "

after about 15 hours of research and data collecting Pablo has stated the below quote:

Most people use their food within 2 years of their purchase, so time frame is not a problem - as long as the food is not moldy. If the container is sealed (never been opened), very little oxidation is taking place, so theoretically it could last as long as 5 years.


followed by the following quote:

If stored in a cool, dry environment, there should be no need to freeze the main pail for the first 12 months of storage.
After 12 months it wouldn't hurt to store the remaining food in the freezer. Either way nutrient loss should be fairly minimal.

We'll all try and do better at meeting your expectations.

ANY natural food source deteriorates over time.  Freezing slows the process, but does not stop it.

I once cleared out an on line seller of all of his Dainichi food (similar to NLS - high quality) that had passed its expiration date.  I used it for 2 years past that date and no fish appeared to suffer a negative impact.

If a big bucket is too much for you - ask a fellow fishkeeper to share it with you.

I'm not sure your going to get a data study on the shelf life of flake food - if you find one, please share. And how do you know its 8 months old - is there a "born-on" date?  I think Danichi does this, but not sure about NLS.  If not, who knows how old your flake is.  Anywho, if the fish are eating it, use it.  Stick the bulk of whatever you have within the freezer and take out portions for short-term, periodic use.  If you are worried that there is a retard of nutrients, mix what you you have with a newer flake food. 

I am on the last portion of flake food that I purchased about 18 months ago and kept within a freezer.  I just made a 4lb order of various flake food from Wet Thumb that I'm sure will last me about the same length of time, if not longer.  My "data," for what its worth.

ANYBODY HAVE ANY DATA  ON HOW LONG IT WOULD KEEP?

I am presently using some NLF in a screw top canister which is 8 months old.
The fish DEVOUR it!!! Is 2 years out of the question?

I pack my flake is ziplock type baggies and put them in the veggie crisper in the fridge.
