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.
