Does Protafloc expire?

I'm using Protafloc Copper Finings for clearing the brew from proteins by adding it to the boil 15 minutes before the end of it. The product's made from red seaweed (Eucheuma Cottonii): http://www.brupaks.com/protafloc.htm.

According to what it says on the package, best before date of this product expires next month. I've read that a similar product - Irish Moss - almost never expires (Does Irish Moss expire?) How is it with Protafloc - should I worry about that expiry date, for how long would it still do its work? Could I extend the period by keeping it in the fridge or freezer? If it does start to lose its potency, is it OK to just increase the amount or are there some drawbacks?

  • Store in cool conditions, away from direct sunlight
  • Keep containers sealed when not in use
  • Maximum storage temperature - 30°C
  • Recommended storage temperature - 10 to 15°C
  • Minimum storage temperature - Not applicable
  • The shelf life at the recommended storage temperature is 2 years from date of manufacture

Increasing the amount is NOT recommended (see the links above).

I am not sure what happens when it expires, but I might test it with a small batch of beer to ensure that it does not ruin the beer.

Otherwise, email the manufacturer and ask them.
