黄油的历史可以追溯到人类驯养动物并开始采集牛奶的时期,至今已有数千年的历史。在古代,黄油被视为珍贵的物品,用于宗教祭祀和医药,不同文化对黄油的重视程度也不同,有些文化将其视为珍宝,有些则轻视之。 制作黄油的过程相对简单,只需将奶油搅打,使脂肪与乳清分离即可。这一过程涉及到乳液的相转化,最终形成固态的黄油。 黄油的起源难以确定,但很可能在不同地区被独立发明。在古代美索不达米亚、埃及和印度,黄油的用途各异,有的用于宗教仪式,有的用于医药,有的则成为重要的食物来源。古希腊和罗马人则更偏爱橄榄油,将黄油视为野蛮人的食物。 中世纪时期,天主教的四旬斋规定限制了黄油的食用,但由于黄油在北欧地区是重要的食物来源,人们会花钱购买许可证,允许在四旬斋期间食用黄油。 文艺复兴时期,随着贸易的增加,黄油在南欧地区逐渐普及。在早期美国历史上,黄油是农村生活中重要的食物和商品,家庭会自己制作黄油用于自用和交易。 19世纪,黄油生产实现了工业化,离心式奶油分离机和机械搅拌机的发明提高了黄油的生产效率,冷藏技术的进步使得黄油能够长距离运输和保存。黄油的工业化生产使其价格降低,并成为欧美饮食中的主要食物。 20世纪,人造黄油的出现对黄油市场造成冲击,但21世纪,随着手工食品和传统烹饪方法的复兴,黄油重新受到欢迎,成为高品质食品的象征。 如今,黄油产业规模庞大,并在不断发展,它不仅是重要的食物来源,也承载着丰富的文化内涵。

Chapters
Butter is a dairy product made by churning cream. This process separates the milk fat from the liquid buttermilk, creating a solid emulsion with about 80% fat. Making butter involves agitating cream to disrupt its emulsion, causing fat globules to clump together and form a solid mass.
  • Butter is about 80% fat.
  • Cream is 18-40% butterfat.
  • Homogenization prevents cream from separating in milk.
  • Churning cream causes fat globules to clump and form butter.

Shownotes Transcript

Ever since humans domesticated animals and realized they could extract milk from them, they have been making and consuming butter. 

While we might not think much of butter today, at one point, it was so prized that it was given as an offering to the gods. 

While some cultures prized it, others looked down upon it and some elevated the production and use of it as an art form. 

Learn more about butter, what it is, how it is made and how it has been used throughout history on this episode of Everything Everywhere Daily.
