What effects does temperature have on the rate of spoilage of milk?I am supposed to plan and design a lab report on this so the answer must have a...

Milk like most other foods that we can consume allows the
growth of micro-organisms that use the nutrients in milk and in many cases are harmful
for our health. To extend the useful life of milk it is pasteurized. But just
pasteurization alone does not allow the milk to be stored at any temperature. The rate
of growth of harmful bacteria increases as the temperature at which the milk is stored
is increased.

Milk can be safely stored for up to two weeks
if the temperature it is kept at is close to 32 F. Harmful bacteria cannot grow in milk
when the temperature it is kept at is below 45 F.

At higher
temperatures, the rate of growth of harmful bacteria is very fast. It has been observed
that with every 18 F increase in temperature above 45 F, bacteria grow at twice the
rate.

To design your report you could keep the milk exposed
to the environment and at different temperatures. Record how long it takes for the milk
to get spoiled, this can be inferred from the milk splitting.
