Non-thermal sterilization method for apple cloudy juice

The invention discloses a liquid food novel non-thermal sterilization method, in particular a non-thermal sterilization method of cloudy apple juice which belongs to the food processing technology field. The technical scheme includes adopting the aseptic operation to send the cloudy apple juice into a reaction vessel and adopting pulse type carbon dioxide with high density for the sterilization. The concrete operation step is: firstly, pumping carbon dioxide with high density into the reaction vessel; secondly, treating for a certain period at the set temperature and pressure condition; thirdly, releasing the carbon dioxide after the treatment to lower the pressure in the reaction vessel to the normal pressure; fourthly, operating the steps from the first to the third repeatedly for more than two times for the pulse type carbon dioxide with high density treatment. The killing effect of Escherichia coli in the cloudy apple juice which is processed in the invention can achieve the result of lowering at least five logarithms to satisfy the commercial aseptic requirement.

Method and apparatus for automated active sterilization of fully implanted devices

The current invention provides this advance in infection control via its unique application of active sterilization to a catheter or implant. While most catheters, and many implants, are passive devices, the current invention will provide an active component as a integral part of the implanted catheter or device to continuously or intermittently sterilize the exposed surfaces / areas of the device. This active sterilization may be accomplished by a variety of mechanisms, including, application of heat, RF, microwave, ultrasound, ultraviolet radiation or other energy capable of sterilizing the device or dislodging any problematic Biofilm that may form. The active sterilization may also employ the pumping of a sterilizing chemical from all attached drug reservoir, the use of electricity or freezing temperatures or any other mechanism for either inhibiting, killing or dislodging any infectious material in contact with the implant. One major advantage of this design is that through the use of small, battery powered or inductively powered sterilization element, the implanted catheter or device can be effectively sterilized without requiring the standard removal surgery, waiting period, then replacement of the infected device. This is expected to translate into greatly improved outcomes (particularly for devices where infection may be catastrophic, ie a prosthetic knee or hip), greatly improved costs, and greatly improved longevity of susceptible devices (ie IV ports, etc.).
