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.
Some people buy raw, uncured ham, others packaged and fully cooked or fully cooked and packaged ham slices. The question that is common for those people is whether or not they can freeze ham. Short answer to this question is: yes, you can freeze ham, cooked or uncooked, packaged or not, sliced or whole. The only situation when you shouldnât freeze ham is when itâs canned and itâs still unopened. Once you open the can, you can always take the meat and freeze it (not in the can though).
