A vacuum source is necessary to allow the process of Freeze drying or vacuum concentration to take place more efficiently by removing the air and thus reducing the pressure in the system With Freeze drying in order to start the removal of moisture in the process the pressure surrounding the material has to be brought down to a value below the triple point value whilst still keeping the able to facilitate water absorption improve sensory characteristics (10 10 10 mm) were freeze-dried using a freeze-dryer (DRC-1000 EYELA Tokyo Japan) These freeze-dried samples were kept in a vacuum wrapping until further use Cross-sections of freeze-dried noodles were mounted on the specimen holder and coated with gold–palladium alloy in vacuum for 90 s The morphologies of
