DESAIN DAN UJI PROTOTIPE ALAT PASTEURISASI SUSU BERBASIS TEKNOLOGI IRRADIASI ULTRAVIOLET (Kajian Dosis UV)

Abstract: The  process  of  milk  pasteurization  generally  use  thermal  method.  The  method  can  cause microorganisms  inactive on the other side, the method result in the degradation of quality food. An  alternative  method  that  can  be  used  is  by  using  technology  of  ultraviolet    irradiation. Ultraviolet  light  has  short  wavelength  with  a  very  strong  antimicrobacterialenergy.The mechanism of its wor  is by absorbing the energy by nucleid acid without causing damaged  on the surface of cel. The absorbed energy will cause the bonding of tymine (dimer tymine) so that the  function  of  nucleic  acid  is  disturbed  and  it  cause  the  dead  of  microorganism (Lay  and  of Hastowo,  1992). The  devices used  in  this  research are ultraviolet lamp type  C,  spiral hose, supporting frame, materials containers and the devices for measuring the amount of microbes, fat,  specific  gravity  and  colour. Materials  used in  this  research is  fresh  milk  that obtained  from KUD  DAU  Malang.  The  result  are  pasteurization  process  with  UV  irradiation  decrease microorganisms and fat in milk.
