Current Applications of Ultrasound in Fruit and Vegetables Osmotic Dehydration Processes

Osmotic Dehydration Process for Preservation of Fruits and Vegetables

Osmotic dehydration has received greater attention in recent years as an effective method for preservation of fruits and vegetables. Being a simple process, it facilitates processing of fruits and vegetables such as banana, sapota, fig, guava, pineapple, apple mango, grapes, carrots, pumpkins, etc. with retention of initial fruit characteristics viz., colour, aroma, texture and nutritional comp...

Rationalization of Sucrose Solution Using During the Fruit Osmotic Dehydration

Th e model of sustainable energy production of dried fruit conducted by using combined technology – the model that has been developed at the Faculty of Agriculture in Novi Sad – includes osmotic dehydration of fruit in sucrose solution. During the process of dehydration the moisture content of the solution is increased due to mass transfer of moisture from fruit. Th is article examines diff ere...

The Effect of Ultrasound-Assisted Osmotic Dehydration Pretreatment on the Convective Drying of Apple Slices (var.Golab)

Drying is one of the widely used methods of food preservation and it is a sensitive food processing operation due to undesirable changes in the quality of dried product. In this study the effect of osmotic dyhedration and ultrasound pretreatment prior to convective drying on quality properties of apple slices was investigated. Apple slices were pretreated by osmotic dehydration in two concentra...

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

modeling and optimization of ultrasound assisted osmotic dehydration of cranberry using response surface methodology

in this study, we investigated the effects of osmotic process with or without ultrasound on solid gain (sg) and water loss (wl) of cranberries. response surface methodology was used to model and determine the optimum processing conditions for wl and sg during osmotic dehydration of samples. sucrose (40-60%) and salt (0-8%) concentrations, temperature (30-50°c) and frequency of ultrasound (0-130...
