摘要: 以猪血红蛋白为研究对象,研究添加5 g/100 mL的葡萄糖对冷冻干燥血红蛋白色差值和水分含量的影响,分析不同pH值、温度和NaCl浓度对血红蛋白色素稳定性的影响。结果表明:添加葡萄糖能够显著提高血红蛋白的亮度L*值和红绿度a*值,并且降低高铁血红蛋白含量(P<0.05);添加葡萄糖可显著提高血红蛋白对pH值、温度、NaCl浓度的稳定性(P<0.05)。当pH 7、温度低于60 ℃、NaCl浓度为0.6 mol/L时葡萄糖处理组中血红蛋白的稳定性最高。

Abstract: We studied the effect of adding 5 g/100 mL glucose on the color and residual water content of freeze-dried hemoglobin and explored the influences of pH, temperature and NaCl concentration on the stability of freeze-dried hemoglobin. The results showed that glucose could improve the L* and a* values of hemoglobin, and decrease the relative content of methemoglobin. Besides, glucose could significantly enhance the stability of hemoglobin to pH, temperature and NaCl concentration. Meanwhile, the stability of glucose-treated hemoglobin was the highest under the conditions of pH 7, temperatures below 60 ℃ and NaCl concentration of 0.6 mol/L.

Key words: hemoglobin, glucose, freeze-drying, stability
