本研究探讨了不同振幅水平的影响（40、70和100%），超声处理温度（40、50和60°C）和暴露时间（3、7、11 min）对稳态剪切特性、表观粘度（η）、剪切应力（σ）、稠度系数（K）、流动性指数（n）和动态剪切特性的影响;基于葡甘露聚糖的Salep溶液（SS）和Salep饮料（SD）样品的储能模量（G ′）、损耗模量（G ″）、复数粘度（η ε）、复数模量（G ε）和损耗角正切（tan δ）值。此外，稳态和动态剪切性能进行了优化，使用脊分析的振幅水平，超声处理温度和曝光时间水平。增加振幅和超声处理时间可显著降低Salep分散体（SS和SD样品）的η、σ、K、G′、G″和η σ值。然而，超声处理温度并没有对这些性能的显着影响。
The present study investigated effect of different amplitude levels (40, 70 and 100%), sonication temperatures (40, 50 and 60°C) and exposure times (3, 7 and 11min) on steady shear properties; apparent viscosity (η), shear stress (σ), consistency coefficient (K), flow behavior index (n) and dynamic shear properties; storage modulus (G′), loss modulus (G″), complex viscosity (η∗), complex modulus (G∗) and loss tangent (tan δ) values of glucomannan based salep solution (SS) and salep drink (SD) samples. In addition, the steady and dynamic shear properties were optimized using ridge analysis in terms of amplitude level, sonication temperature and exposure times levels. Increasing amplitude level and sonication time decreased considerably the η, σ, K, G′, G″ and η∗values of salep dispersions (SS and SD samples). However, sonication temperature did not have a remarkable effect on these properties.
