Biological Heart Valves. Biological Heart Valves are made of tissues and valves derived from animals or human donors. Their biggest advantage is that they do not cause blood clotting on their surface and truly replicate the form and function of the normal human valve.
The biggest difference between cured and uncured is the fact that the uncured uses natural curing agents, such as celery powder, which transforms into nitrite when it is processed. Thus, uncured products have labels with: âNo Nitrates or Nitrites added except those naturally in celery powder or juiceâ.
Hams may be fresh, cured, or cured-and-smoked. Ham is the cured leg of pork. Fresh ham is an uncured leg of pork. Fresh ham will bear the term fresh as part of the product name and is an indication that the product is not cured. Turkey ham is a ready-to-eat product made from cured thigh meat of turkey.
