【摘要】 对温度、日光光照等条件以及不同添加剂对藻蓝蛋白水溶液稳定性的影响进行研究。研究得出,藻蓝蛋白应低于40℃避光保存,应于中性条件下保存;葡萄糖、氯化钠和山梨糖醇可以有效提高藻蓝蛋白的稳定性,分别于室温放置72 h后藻蓝蛋白色素保存率从50.90%提高到了78.10%、67.02%和69.08%;按质量比1∶1∶0.3复合葡萄糖、氯化钠和山梨糖醇作为稳定剂加入藻蓝蛋白后于4℃放置14 d,藻蓝蛋白色素保存率比未加添加剂的藻蓝蛋白提高54.4%;于25℃下放置,加了复合添加剂的藻蓝蛋白色素保存率比未加添加剂的提高16.1%。更多还原

【Abstract】 The influence of temperature,daily light,p H value and different additives on stability of phycocyanin were studied. The results showed that phycocyanin should be stored under 40 ℃ in dark place;and it was appropriate to be stored under neutral condition;glucose,sodium chloride and sorbitol could improve the stability of phycocyanin. Phycocyanin with preservatives consist of glucose,sodium chloride and sorbitol stored in daily temperature for 72 h made the pigment remain ratio of phycocyanin increased from 50.90 % to 78.10 %,67.02 % and 69.08 %;the pigment remain ratio of phycocyanin with composite of glucose,sodium chloride and sorbitol in proportion of 1 ∶ 1 ∶ 0.3(mass ratio)stored in 4 ℃ for 14 days was 54.4 % higher than pured phycocyanin’s;the pigment remain ratio of phycocyanin with additives stored in 25 ℃ was 16.1 % higher than pured phycocyanin’s.更多还原
