摘要
草金鱼总色素光谱吸收峰在400～600nm,系类胡萝卜素色素。在不同酸碱度、维生素和有机物作用下,该观赏鱼总色素稳定性各不相同。环境pH值过高或过低对该色素具有强烈的破坏作用,中性pH值溶液利于该色素的有效保存;Vc和VE对该色素具有保护作用,但是当Vc剂量不适时,该色素遭到严重破坏,VK对该色素具较强的破坏作用;乳酸对该色素具有增色作用,苯甲酸、草酸、柠檬酸,丙二酸和反丁烯二酸对该色素具有保护作用,乌头酸、水杨酸、顺丁烯二酸、亚油酸、萘乙酸、溴丙酸和苹果酸对该色素具有破坏作用,其中以苹果酸的破坏作用最强。淀粉对该色素具有保护作用,葡萄糖和蔗糖则具有破坏作用,其中以蔗糖的破坏作用最强。研究结果提示:在提取、保存该色素以及配制增色饵料时,要特别注意避免不良因素的影响,确保试验结论的正确和增色效果的良好。
Carotenoid, as the total pigment in grass goldfish (Carassius aurutus), had spectral absorption peaks at 400～600 nm and varied with pH, vitamins and organic compounds in stability. The carotenoid was destroyed at high or low pH and dosage of vitamin C, while it can be well conserved in neutral condition and in vitamin C and E. Lactic acid, benzoic acid, oxalic acid, citric acid, malonic acid, amylum, and fumaric acid had the effect of protection of the pigment while aconite acid, salicylic acid, maleic acid, linoleic acid, glucose, sucrose, naphthylacetic acid, bromopropanoic acid and malic acid destroied the pigment.
