This study evaluated the chemical properties (polyphenol and genistein contents) of soybean extracts obtained by biotransformation and dried by spray dryer at different conditions and their in vivo ability to inhibit 12-O-tetradecanoylphorbol-13-acetate- (TPA-) induced biochemical alterations in the skin of hairless mice. By comparing the obtained data with that of the well-known active soybean...

Diabetes is considered one of the main threats to global public health in this era. It is increasing rapidly in every part of the world; the prevalence of the disease will grow to the point where 366 million people will be affected by 2030. The prevalence of diabetes mellitus (DM) in the Saudi population is high, and the majority of patients suffer from type 2 DM. Marketed oral antidiabetic dru...

The main goal of this research was to develop a mathematical model for co-current spray drying-assisted encapsulation natural extracts from grape pomace and citrus fruit peels, aiming predict both structural features the retention their bioactive constituents. Model validation performed using laboratory scale dryer, analyzing product in terms moisture content, solids total phenolic compounds re...

This work aimed to study the effect of emulsion properties on the microencapsulation of orange essential oil by spray drying. The study was performed using a 2 central composite design, where the independent variables were the total solid content (0-30%), the ratio of oil/total solids (0-30%) and the homogenization pressure used for emulsification (0-1000 bar). Whey protein concentrate and 20 D...

Application of tray dryer is widely used in agricultural drying because of its simple design and capability to dry products at high volume. However, the greatest drawback of the tray dryer is uneven drying because of poor airflow distribution in the drying chamber. Implementing the proper design of a tray dryer system may eliminate or reduce non-uniformity of drying and increases dryer efficien...

In this paper, we develop an economically optimizing Nonlinear Model Predictive Controller (E-NMPC) for a complete spray drying plant with multiple stages. In the E-NMPC the initial state is estimated by an extended Kalman Filter (EKF) with noise covariances estimated by an autocovariance least squares method (ALS). We present a model for the spray drying plant and use this model for simulation...
