Cheese is
a solid food made from the curdled milk
of cows, goats, sheep, or other mammals.
The milk is curdled using some
combination of rennet (or rennet
substitutes) and acidification.
History
Cheese is an ancient food whose origins
may predate recorded history. Probably
discovered in Central Asia or the Middle
East, cheese making spread to Europe and
had become a sophisticated enterprise by
Roman times. As Rome's influence
receded, distinct local cheese making
techniques emerged. This diversity
reached its peak in the early industrial
age and has declined somewhat since then
due to mechanization and economic
factors.
Cheese has served as a hedge against
famine and a good travel food. It is
valuable for its portability, long life,
and high content of fat, protein,
calcium, and phosphorus. Cheese is
lighter-weight, more compact, and has a
longer shelf life than the milk from
which it is made. Cheese makers can
place themselves near the center of a
dairy region and benefit from fresher
milk, lower milk prices, and lower
shipping costs. Cheese's substantial
storage life lets a cheese maker sell
when prices are high or money is needed. |
