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.
Uncured hot dogs do not contain artificial nitrates or nitrites. The meat in an uncured hot dog is preserved with celery juice or celery powder, which happen to be a naturally occurring source of nitrates. Uncured hot dogs, like cured hot dogs, are fully cooked and should be prepared the same way. The one thing to remember with uncured hot dogs is to keep them refrigerated until you are ready to use them since they contain no artificial preservatives.
