Abstract
A method for extending shelf life of a biological soft tissue of an object includes introducing one or more cell protecting agents into the extracellular and intracellular space of the biological soft tissue; by impregnating the biological soft tissue by applying a vacuum to the biological soft tissue and then releasing the vacuum, wherein the step of applying a vacuum is performed while the biological soft tissue is immersed in an impregnation solution containing said one or more cell protecting agents, and by gradually decreasing the pressure from atmospheric pressure to a minimum pressure in a pressure falling step during a time of from 1 second to 15 minutes, then optionally keeping the minimum pressure in a pressure holding step during a certain time, and then rising the pressure to atmospheric pressure again in a pressure rising step during a time of from 1 second to 15 minutes.
