摘　　要：以沙棘籽原花色素为原料、亚硫酸为降解剂,应用均匀设计法设计试验,考察降解时间、降解温度、料液比和亚硫酸用量对原花色素降解效果的影响。结果表明:亚硫酸法最佳降解条件为:温度80℃、时间60 min、料液比1∶8(g∶L)、亚硫酸体积分数为12%,在此条件下亚硫酸降解效果明显,降解前平均聚合度为13.42,降解后平均聚合度为7.53。Proanthocyanidins extracted from sea buckthorn seeds were degraded by sulfurous acid used as degradation reagent. Uniform design was applied to optimize the degradation process. Effects of temperature, time, solid-liquid ratio, and the dosage of sulfurous acid on the degradation of proanthocyanidins were studied. The optimized degradation conditions were obtained as degradation temperature 80 degrees C, degradation time 60 minutes, solid-liquld ratio 1 ： 8, and sulfurous acid dosage 12%. The effect of sulfurous acid on degradation of proanthocyanidius was obvious. The average degree of polymerization reached 7.53 after degradation, while it was 13.42 before degradation.
