Time and energy reduction on grape dehydration by applying dipping solution on freeze drying process

Modeling and Optimization of Ultrasound-Assisted Osmotic Dehydration with Finished Freeze Drying on Black Cherries – The Effect on Antioxidant Activities

ABSTRACT: In this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. Freeze drying is a separation process based on the  sublimation phenomenon. This process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...

Sperm freeze-drying; effects on sperm parameters

Today, sperm cryopreservation is a routine practice in infertility clinics. One of the alternative methods to preserve sperm is freeze-drying. This process consists of three steps. The first step is sample freezing, during which the solvent is separated from the solvent. Water forms ice crystals and the solute is placed between the ice crystals. Freezing may be done in a separate device or in a...

Changes in the nutritional content of fruit and vegetables during the dehydration process of freeze drying

Effect of Carboxylmethyl Cellulose Coating and Osmotic Dehydration on Freeze Drying Kinetics of Apple Slices

The effect of different concentrations of sugar solution (hypertonic) (30%, 45% and 60% w/v) and carboxyl methyl cellulose (CMC) (0%, 1% and 2% w/v) coating on freeze drying of apple slices was studied. In total, nine treatments with respect to concentrations of hypertonic solution and coating layer were prepared to analyze their influence on the physical and chemical properties of freeze dried...

Freeze-drying Process Development for Protein Pharmaceuticals

This chapter provides an overview of the impact of protein formulation variables on different stages of the protein freeze-drying process and offers guidance for selection of critical process parameters during protein freeze-drying cycle development, optimization, and scale-up. There is particular focus on practical considerations including large-scale process development, scale-up challenges, ...
