Chitosan

[mikefrommichigan]

I am making a Winexpert Malbec, and was about to use the bag of Chitosan that is included, as per the instructions, and noticed stringy pieces in the bag. I have not seen this before so I decided not to use this bag and found another bag that I had spare.

From wine maker Magazine Oct/Nov 2007.
Chitosan (positive charge): As the name implies, it is composed of chitin, which is the structural element of the exoskeletons of crustaceans, such as crabs, shrimp and other shell fish.

What are the stringy pieces and should they be there? Is the bag safe to use?

Thanks

On Monday I would contact WineExpert with your picture. My guess (and it is really just a guess) is that it is fine. I am sure they will give you a definitive answer.

Good idea Cmason.

I called Winexpert this morning and was told that this sometimes happens. The representative said that before opening the packet you should press and rub the membrane between your fingers for a while and it break up and return to a liquid state. I did this for a short while and it did start to break up slowly. Not sure how long I need to do this for if I want to dissolve it all.
