The Natural Way to Cheese.
Thistlezyme® is a 100% thistle, (Cynara cardunculus), rennet extraction produced by Enzyme Development Corporation at our factory in Scranton, PA, USA. The powder and the liquid versions have standardized activities based on the Milk Clotting Assay. With consistent enzyme activity, the guess work regarding the potency of the enzyme is removed. The activity is the same from batch to batch. This allows the cheesemaker to concentrate on the variables within the milk and not worry about the rennet.
