糖料植物的“后起之秀”长期以来,人们的食糖几乎全部由甘蔗提供的。直到1747年,德国科学家马格拉夫发现甜菜根里也含有蔗糖。在1800年前后,有的国家才开始建立甜菜制糖工厂。算起来,甜菜制糖的历史一共只有一百几十年。利用甜菜作为制糖原料的优点在于:甘蔗只能在热带和亚热带气温较高的地区生长,而且生长期长,世界上有许多地区不能种植;而甜菜原产温凉 The “rising stars” of sugar plants have long provided sugar for people. Until 1747, the German scientist Maglaf found that beetroot also contained sucrose. Before and after 1800, some countries began to build sugar beet sugar factories. In fact, the history of sugar beet is only a hundred years. The advantage of using sugar beet as a raw material for sugar production is that sugar cane can only grow in areas with high temperatures in the tropics and subtropics, and it has a long growth period. Many regions in the world cannot grow;
