动物的身体、植物的体内多少都含有脂肪。脂肪由各种脂肪酸构成,其构成比例因不同种类而有差异。如果使用气体色层谱装置分析,就可以了解到这一比例。动物的死亡或植物的枯死,其脂肪随即分解消失,这在过去已成定论。但是,最近联邦德国科学家推翻了这一结论。明确了即便千、万年以前的动物、随物也含有微量的残存脂肪。这一发现预示着史前时代考古中饮食生活等多领域的研究将会大大地前进。 Animal body, plant body contains fat in the body. Fat is composed of various types of fatty acids, and its composition ratio varies depending on the species. If you use the gas chromatography device analysis, you can understand this ratio. The death of an animal or the withered plant, its fat decomposition immediately disappeared, which in the past has become a conclusion. However, a recent federal German scientist overthrew this conclusion. Even if the thousand, thousands of years ago, the animal also contains traces of residual fat. This finding indicates that research in many fields such as dietary life in prehistoric archeology will greatly advance.
