Microbiological aspects
Goat and sheep milk is perishable and fragile. It
can easily be spoilt if the animals are given unsuitable
feed or are handled in the wrong way before
and during milking, or if the milk is handled incorrectly
during and after milking, including the processes
of cooling and transportation (Haenlein, 1987).
Much more research is needed into somatic cell and
bacteria counts in goat and sheep milk in order to
provide reliable data on bacterial populations and
their origins.
organisms in goat milk with the application of ascending
doses of gamma-irradiation. They observed
a decrease in the total bacteria count in raw goat
milk from 15 X lo3 to 14 X 10 after 0.75 M rad
irradiation. There was no marked change in titratable
acidity or pH in goat milk after exposure to different
doses of gamma-irradiation, but there was an effect
on the organoleptic properties of the milk. Goat milk
tasted slightly caramelized after heat treatment, but
became markedly oxidized on exposure to 0.75 M
rad and there were also detectable changes in the
colour (Grover et al., 1987).
