Nanofiltration treatment of tomato paste processing wastewater: Process modeling and optimization using response surface methodology
Tomato wastewater is characterized by a large amount of suspended solids, red color, and bad smell. In this paper, the effect of transmembrane pressure (10, 15, 20 bar), pH (4, 5, 6) and temperature (30, 40, 50 oС) on the ...
Evaluation of interactions of biopolymers using dynamic rheological measurements: Effect of temperature and blend ratios
Herein, a robust scheme is defined to elaborate interaction behavior of biopolymers and the effect of temperature on it using dynamic rheological measurements. As a case study, sage seed gum-xanthan gum (SSG-XG) interaction ...
بررسی کاربرد پردازش تصویر در ارزیابی ریز ساختار بستنی
بستنی سیستم پیچیده ای است که سلول های هوا، بلورهای یخ و چربی در فاز سرمی آن پخش شده اند و ریز ساختار آن تاثیر زیادی بر کیفیت محصول نهایی دارد. در این تحقیق با استفاده از پارامترهای تصویر(قطر معادل حباب، تخلخل، انتروپی و ...
Rheological characterization of hydrocolloids interaction: A case study on sage seed gum-xanthan blends
In this paper, a first robust scheme for in-depth rheological study on the interaction of two attractive hydrocolloids (sage seed gum (SSG) and xanthan gum (XG) at five blending levels (1-0, 3-1, 1-1, 1-3, and 0-1)) was ...
Temperature dependency of the interaction between xanthan gum and sage seed gum: An interpretation of dynamic rheology and thixotropy based on creep test
The viscoelastic (transient and dynamic) and time-dependent rheological behaviors of XG (xanthan
gum), SSG (sage seed gum) and their blends at various ratios (1-3, 1-1, and 3-1 SSG-XG) and temperatures
(10, ...
Influence of temperature on sage seed gum (Salvia macrosiphon) rheology in dilute and concentrated regimes
Herein, the influence of temperature (10°C, 30°C, 50°C, 70°C, and 90°C) on the dynamic (using amplitude sweep, frequency sweep, and temperature sweep tests), steady-shear, thixotropy (using hysteresis loop, single shear ...
Kinetic Modelling of Hydraulic Resistance in Colloidal System Ultrafiltration: Effect of Physiochemical and Hydrodynamic Parameters
In this work, different kinetic patterns (homographic, exponential-linear and exponential) of hydraulic resistance in ultrafltration process of a colloidal system have been investigated. Exponential kinetic model, as the ...
Thermo-rheology and thermodynamic analysis of binary biopolymer blend: A case study on sage seed gum-xanthan gum blends
In this study, the effect of different temperature sweep modes (gradient (TGS), table (TTS) and profile (TPS) at heating/cooling rates of 1, 11 and 36.53 °C/min, respectively) were elaborated on the interaction behavior ...
Hydrocolloid clustering based on their rheological properties
In this study, we proposed an objective classification of seven commercial hydrocolloids and
four novel hydrocolloids. Total of 74 rheological parameters was generated by steady (flow
behavior, hysteresis ...
