高酰基结冷胶与κ-卡拉胶复配胶的质构特性研究
Texture properties of high acyl gellan and κ-carrageenan mixed gels
摘要
Abstract
Compression tests and texture profile analysis(TPA) were used to test the strength,deformability and hardness of mixed gels with high acyl gellan and κ-carrageenan.The influences of Ca2+,Mg2+,K+,Na+ and different HA∶CA ratios on the texture properties of the mixed gels were investigated.The total polymer concentrations of the gels in our study were all at 1%(w/v).Ion concentrations of the samples were set as 2~80mmol/L,and the ratios of HA∶CA were 25∶75,50∶50 and 75∶25.The result showed that divalent cations significantly influenced the texture of the mixed gels compared with monovalent cations,and Ca2+ was the most effective cations in the study.The strongest synergistic interaction occurred when the ratio of HA∶CA was 75∶25 and the mixed gels of high acyl gellan and κ-carrageenan had a good deformability.关键词
