英語時(shí)差：歷史最悠久的甜味劑（上）

Honey has been around for a very long time. Cave paintings in Spain from over ten thousand years ago show people harvesting honey. Today honey is mostly used for its distinctive flavor, but for baking it has another advantage as well: baked goods made with honey take longer to get stale. Honey helps baked goods stay fresh longer because, unlike common table sugar, honey is made of two so-called “simple” sugars: glucose and fructose. Table sugar also has glucose and fructose, but they’re chemically bonded together in a double sugar called “sucrose.” Having two single sugars instead of one double sugar means that ounce-for-ounce honey contains more sugar molecules, which is why honey is also a little sweeter than table sugar.
