range,  the higher  the temperature,    the faster
the enzymes work.   Some    accelerated “aging”
can take    place   during  cooking.    If  meat    is
quickly seared  or  blanched    in  boiling water   to
eliminate   microbes    on  its surface,    and then
heated  up  slowly  during  the cooking —   for
example,    by  braising    or  roasting    in  a   slow
oven    —   then    the aging   enzymes within  the
meat    can be  very    active  for several hours
before  they    denature.   Large   50  lb/23   kg  slow-
roasted “steamship” rounds  of  beef    spend   10
hours   or  more    rising  to  120–130ºF/50–55ºC,
and come    out more    tender  than    small   portions
of  the same    cut cooked  quickly.
Aging   Meat    in  Plastic and in  the Kitchen
Despite the contribution    that    aging   can make
to   meat    quality,    the     modern  meat    industry
generally   avoids  it, since   it  means   tying   up  its
assets  in  cold    storage and losing  about   20% of
the meat’s  original    weight  to  evaporation and
laborious    trimming    of  the     dried,  rancid,
