Preserving food has not always been easy.
Centuries ago,people gathered ice from streams
and ponds and did their best to store it year-round
in icehouses and cellars,so they had a ready supply
to keep their food cold,Even with ice people were
often limited to eating locally grown foods that had
to be purchased fresh and used daily.
The Egyptians,Chinese and Indians were some of the
early people to use ice in food preservation.
In 1626, Sir Francis Bacon was also testing the idea
that cold could be used to preserve meat; his chilly
experiment caused him to develop pneumonia,
from which he died on Easter Day, April 9, 1626
保存食物並不總是那麼容易。
幾個世紀以前，人們從溪流收集冰
和池塘，並盡最大努力，以存儲它全年
在冰庫和地窖裏，所以他們有現成的供應
爲了保持食物的低溫，即使是在有冰的情況下
通常只能喫當地出產的食物
新鮮購買，每天使用。
埃及人、中國人和印度人就是其中的一些
早期人們用冰來保存食物。
1626年，弗朗西斯·培根爵士也在試驗這個想法
這種冷可以用來保存肉;他的冷
實驗使他患上了肺炎，
他死於1626年4月9日復活節
