甜菜是藜科(Chenopodiaceae)甜菜属植物,国内外现有的糖甜菜品种,均属于普通甜菜Beta vulgaris L.的糖用甜菜变种Beta vulgaris L.var.saccharifera Alef.,糖用甜菜的根产量和含糖率均较高,含糖可达18%左右,有的高达21%以上,是制糖工业的好原料。甜菜碱是在甜菜根中的一种季胺型水溶性生物碱,在新鲜的甜菜中其含量达0.3～o.7%。在结晶工段糖浆中,甜菜碱积累到3%(对于固物),在废蜜中为8%(对于固物),Kubadinou对某些废蜜样品测得的甜菜碱值为12.5%(对于固物)。在栽培中甜菜碱的
Beet is a plant belonging to the genus Betaopodiaceae of the genus Chenopodiaceae. The existing sugar beet varieties at home and abroad belong to beta vulgaris L. var. saccharifera Alef. which belongs to Beta vulgaris L., and the root yield of sugar beet With high sugar content, the sugar content is up to 18%, and some are as high as 21%. It is a good raw material for the sugar industry. Betaine is a quaternary amine-type water-soluble alkaloid in beetroot. Its content in fresh beets is 0.3-o.7%. In the crystallization section syrup, betaine accumulates to 3% (for solids) and in honey 8% (for solids), Kubandinou measures 12.5% for certain waste honey samples (for solids) Thing). In the cultivation of betaine
