CAS号：

性质： 又称番茄烯。系类胡萝卜素化合物之一，但无维生素A的活性。深红色针状结晶。熔点172～175℃。溶于苯、氯仿、三氯甲烷、二硫化碳、乙醚、石油醚、己烷等。几乎不溶于甲醇、环己烷、乙醇；可在二硫化碳加乙醇中结晶，从二氯甲烷加甲醇中重结晶。其光吸收特征(反式)：446nm，472nm，505nm(2250，3450，3150)。番茄红素在溶液中易发生异构化，结晶后不易发生异构，但易自氧化，特别在空气中，故应真空保存于-20℃，暗处或保存在干燥、不含酸的氮气或二氧化碳气体中。番茄红素广泛存在于自然界中，尤以番茄、粉红色葡萄柚、棕榈油中含量较丰富。可从成熟番茄中提取(1kg新鲜成熟番茄约可得0.02g)或由化学合成法制得。为一种红色素。用合成法制得产品，主要作为食品添加剂的人造色素。
