Does the chitosan oligosaccharide powder have a shelf life?

Big props to OO as well, I'm a smarter person because of you, thanks for sharing.

I didn't want to go there but that was just great!

Yes, it does. But if stored properly (protected from light, moisture, and heat) it should be at least +5 years, likely a lot more. The main issue is the amine group which can bet oxidised. This should result in a colour change (yellowish at first, later reddish or brown) which you will only see with white high quality stuff and it should also start to smell bad. If you have a colour-, smell-, and tasteless powder, then it's easy to tell when it's degrading beyond usability .
If you have a salt form such as the lactate, the the stability is considerably increased compared to the free base. The hydrochloride on the other hand might be somewhat more susceptible to humidity resulting in slow de-polymerisation (though, that's just an estimate).
I'm sitting on some glucosamine HCl (that's the monomer) since 2008 and it just looks the way it did when I first got it.

If you have too much and don't know what to do: seal it and store it in the fridge or even the freezer. Most pure compounds will live a very long life like that but only if you thaw them well before opening the 'container' or you get condensations and then *RIP*.

EDIT:
BTW properly done whole cockroach hydrolysate will also contain amino acids, sugars, and hydrolysed fat which also functions as surfactant/wetter/sticker. An elaborate workup beyond filtration and pH adjustment won't be needed .
And here a few pics from my former cockroach collection... unfortunately, I had to stop that hobby as they didn't like the climate after moving and with the passing of my last bearded dragon there was no one left to eat 'em.

Crustaceans also contain chitin. Crab meal is an excellent source of Ca and chitin. Crab hydrolysate would be good

Microbial activity breaking down Chitin creates the Chitinase enzyme and it's this enzyme that prevents insect eggs from maturing thereby preventing the larva to mature.

Chitosan is manufactured using bacteria to harvest this enzyme. I've never used the manufactured products.

Im with Coot on this. Plus, if you add malted barley teas you will ramp up the chitinese levels tremendously. $60 for 50 lbs of malted barley...used at 1 oz per gallon. You do the math. What's a better deal?

Me not so much: The statements

Microbial activity breaking down Chitin creates the Chitinase enzyme

and

Chitosan is manufactured using bacteria to harvest this enzyme.

are pure nonsense...

Do you happen to have a reference for your claim that malted barley tea induces chitinase expression and could you elaborate why this is the case (e.g. active constituents?)? Thanks!

Safe to use ?
Did some One make à chart to use it?
C Lear with pic with and not?

Hey Chine
It is good to see you around.
Are you still working your finger down to the chop sticks?
Here is a nice pic explaining things a bit also


Don't worry about killing your crop as OO says it is very safe I just added 1000 ppm 1 gram per liter of Chitosan Oligosaccharide lactate
For the last week and I noticed a decent increase in trichome production. but start at 100 PPM and work your way up.
Chitosan Oligosaccharide lactate is so safe you can eat it.
Here https://www.ebay.com/itm/CHITOSAN-Oli...item27f7a4b8b4
Supposedly this stuff is 14 times more effective in bio-activity than any other form chitosan
I have also read they use Chitosan to replace skin on wounds and even used on the human eye...wow!
This stuff is very versatile and an amazing compound not just for growing.
Try not to work so hard Master Chine, maybe we will see you around more!

Just pointing this out, but glucosamine is the mono unit of chitosan (monosaccharide vs polysaccharide). They're both made from the same stuff, chitin. Actually I'd be surprised if the glucosamine you buy in pill form is 100% broken down to the monomer. There's probably a percentage of chitosan in it. It's readily available and cheap everywhere. Might not hurt to give it a try instead as a foliar treatment.

[Unicorniclops]

I was reading patents on how the above is made (crustaceans). It looks like the fermentation process produces roughly a 1:1 ratio of glucosamine:chitosan which is present in the water layer when they centrifuge it. I'm not sure how this is further processed, but I did find an agricultural patent that used a foliar spray consisting of about 2% chitosan and 2% glucosamine.
