摘要: 以还原糖得率为指标,研究了水解时间、水解温度和硫酸浓度对红枣多糖水解的影响,在单因素试验的基础上采用正交试验优化红枣多糖水解的工艺条件;对水解产物的吸湿性能和保湿性能进行研究,并考察主要水解产物还原糖含量与其吸湿性能和保湿性能之间的相关性.结果表明:红枣多糖水解的最佳工艺条件为水解时间120 min, 水解温度70 ℃,硫酸浓度0.15 mol/L,在此条件下还原糖得率为97.56%;红枣多糖水解产物具有较强的吸湿性和保湿性,相同条件下与甘油差异不显著;水解产物的吸湿性能、保湿性能与还原糖含量均呈正向线性相关,且线性相关系数分别为0.905和0.919.红枣多糖水解产物在食品、化妆品生产领域有很好的应用前景.

Abstract: Using reducing sugar yield as index, the effect of hydrolysis time, hydrolysis temperature and sulfuric acid concentration on jujube polysaccharide hydrolysis was studied. Based on single factor test, orthogonal test was used to optimize the jujube polysaccharide hydrolysis conditions. Then the hygroscopicity, moisture retention of hydrolysis product were studied. And the correlation between the reducing sugar content of hydrolysis product and its hygroscopicity and moisture retention was investigated. The results showed that the optimization conditions of jujube polysaccharide hydrolysis were as follows: hydrolysis time 120 min, hydrolysis temperature 70 ℃, sulfuric acid concentration 0.15 mol/L. Under this condition, the reducing sugar yield was 97.56%. The jujube polysaccharide hydrolysis products had good hygroscopicity and moisture retention, no significant difference than that of glycerol in the same conditions. The hygroscopicity and moisture retention of hydrolysis product had positively linear correlation with reducing sugar content, and the linear correlation coefficient were 0.905 and 0.919,respectively.The jujube polysaccharide hydrolysis products had a good application prospect in the field of food and cosmetics production.
