【摘要】 综述了β胡萝卜素的生产方法,介绍了以C14醛为原料和以维生素A为原料的化学合成品生产方法和天然品的生产方法,包括从天然植物、蚕粪、盐藻中提取和微生物发酵法。β胡萝卜素工业化生产的前提是解决好发酵工艺、细胞破碎技术及高效提取纯化技术。目前天然β胡萝卜素的需求增长率大于化学合成品,天然品的售价约为化学合成品的3倍。更多还原

【Abstract】 The technologies for producing the synthetic β-carotene chemically and natural product based on C 14 -aldehyde and vitamin A are introduced, including the method of extraction from natural plants, silkworm feces, salt alga and the method of microbe ferment. Improving the fermentation technique, cell crash and high efficiency extraction and distillation technology are the prerequisites for commercial production of β-carotene. At present, the increase rate of demand on natural product of β-carotene is higher than that of chemically synthesized, and the price of natural product is 3 times as many as the latter.更多还原
