1
糊粘度和冻融稳定性达到了黑糯玉米淀粉的水平。
The paste viscosity and freeze-thaw stability are close to those of black glutinous maize starch.
2
结果表明，交联度较高时，糊的透明度低，但冻融稳定性较好。
The results indicated that its paste clarity decreases when its degree of cross-linking grows, but its freeze-thaw stability is better.

结果表明，香芋淀粉糊具有透明度低，冻融稳定性差，沉降性好等性质。
The results showed that Colocasia esculenta Schott starch has properties of lower clarity, poor freeze-thaw stability and good retrogradation.

冻融稳定性
冻融稳定性是由于乳液体系主要由聚合单体、水、乳化剂及溶于水的引发剂等基本组分组成，其中约有一半组成是水，乳液及由其配制的涂料在很多情况下要被暴露于冻结的气候条件下，当聚合物乳液遇到低温条件时会发生冻结。
