Finding enough meat was a problem for primitive man．Keeping it for times when it was scarce was just as hard．Three ways were found to keep meat from spoiling：salting，drying，and freezing．

People near salty waters salted their meat．At first they probably rubbed dry salt on it，but this preserved only the outside．Later they may have pickled their meat by soaking it in salt water．

In hot，dry lands，men found that they could eat meat that had dried while it was still on the bones．They later learned to cut meat into thin strips and hang it up to dry in the hot air．

Men in cold climates found that frozen meat did not spoil．They could leave their meat outside and eat it when they pleased．

人類儲(chǔ)存肉的三種方法

對原始人類來說，獲得充足的肉是件難事，而把肉類儲(chǔ)存到缺肉的時(shí)令也同樣不容易。人們找到了防止肉類變腐的三種辦法：鹽腌、風(fēng)干和冷凍。

靠近咸水地帶的居民用鹽腌肉。起先，他們可能是把干鹽擦在肉上，但這只能使肉的外部不腐。后來，他們也許就改用咸水浸泡的辦法來腌肉了。

在炎熱、干燥的地方，人們發(fā)現(xiàn)他們可以食用已經(jīng)變干、但仍連在骨骼上的肉。后來，他們學(xué)會(huì)把肉切成薄條，懸掛起來，讓它在炎熱的空氣中變干。

生活在寒冷氣候下的人們則發(fā)現(xiàn)凍肉不腐。他們可以把肉置于室外，高興時(shí)隨時(shí)可吃。
