CRISTALASE®
is a liquid preparation of purified papain, standardized with sorbitol.
Papain is extracted from the green unripe fruit of the papaya tree.
CRISTALASE® is available in different standardized proteolytic activities. CRISTALASE® has been developed on the well-known action of papain on the phenoloprotein bindings formed during cold storage of beer and which are causing chill haze.
