Milk Can Last
Everybody knows milk is
perishable but apparently it
is not nearly so perishable as we
had thought.
Under household refrigera
tion (usually 45° to 50° F.)
milk keeps an average of 7
davs. But tests conducted under
ARS research contract show
that simply lowering the stor
age temperature to freezing or
slightly above will extend the
storage life to as long as 7
weeks.
Long-accepted ideas about
milk perishability were in for
even more of a jolt when the
research showed that milk pas
teurized under higher-than
normal temperatures would
keep as long as 20 weeks and
more.
These findings mav well lead
to drastic changes m the stor
age and distribtuion practices
of the fresh milk industry.
The work was done by the Pet
Milk Company under an ARS
icsearch contract Both winter
and summer milks were pas
teurized under normal condi

tions (165° to 172° F. for 16
seconds) at six Southern dair
ies. Then they were cooled to
32° F. and flown in ice to Pet
Milk’s Research and Develop
ment Center, Greenville, Illi
nois, where they were stored at
32 dgrees, 35 degrees, 40 de
grees, and 45 degrees F. Week
ly bacteriological tests and
evaluations by a trained taste
panel indicated that at the two
lowest storage temperatures
some of the summer milks were
still safe and flavorful after 7
weeks, and the winter milks af
ter 4 weeks.
When these tests demonstrat
ed the value of low-temperature
storage for normally pasteuriz
ed milk, the scientists next tried
higher pasteurizing tempera
tures to see if they could extend
the storage life of milk even
further. With their experiment
al equipment they pasteurized
milk at 200° and 220° F. for
the usual 16-seconds.
They also tried flash-pasteu
nzing at these temperatures for
a half-second.

at the same 4 temperatures as
the commercial samples and
subjected to the same weekly
bacteriological and taste tests.
Only the samples pasteurized at
220° for 16 seconds were still
acceptable by both of these cri
teria after 13 to 20 weeks of
