How do I keep BAC to preserve it best?

BAC is freeze dried at a low temperature and is crystallized in the process. As such, it will keep for many years at normal room temperature. It is best to keep it away from hot stoves or direct sun exposure. Keeping it in a drawer or cupboard is best. It can also be kept in the refrigerator. We recommend not keeping it in the freezer as repeated thawing may initiate loss of enzyme and nutritional strength.
