Developments in osmotic dehydration of fruits and vegetable-a review
Received: 15/11/2013 Revised: 13/12/2013 Accepted: 16/12/2013 Abstract Osmotic dehydration is a process of water removal by immersion of water containing cellular solids in a concentrated aqueous solution of sugar/ salt. This results in intermediate moisture product with lower water activity. At low water activity, most of the chemical reactions which deteriorate the food as well as the growth ...
متن کاملMethods to increase the rate of mass transfer during osmotic dehydration of foods.
Traditional methods of food preservation such as freezing, freeze drying (lyophilization), vacuum drying, convection drying are often supplemented by new technologies that enable obtaining of high quality products. Osmotic dehydration is more and more often used during processing of fruits and vegetables. This method allows maintaining good organoleptic and functional properties in the finished...
متن کاملFactors affecting mass transfer during osmotic dehydration of fruits
Research applications of osmotic dehydration to food processing in technology and in component transfer mechanisms are being carried out in several countries. Osmotic dehydration is a traditional process applied to food dewatering. It leads to attractive products that are ready to eat or can be applied as a pretreatment to the next process such as drying or freezing. The new osmotically dehydra...
متن کاملAn Investigation of Mass Transfer Phenomena during Osmotic Dehydration of Orange Slices
The osmotic dehydration causes water removing from food and also a soluble solid uptake into thefoodstuffs. However, large penetration of solute into the food becomes a major problem in osmoticdehydration.Pre-coating the food to be dehydrated with an artificial, edible barrier was also explored as a wayto efficiently hinder solute penetration. In this study the effect of edible coating (CMC),co...
متن کاملOsmotic dehydration technique for fruits preservation-A review
Fruits are important sources of vitamin and minerals. They are got rotten before the final consumption due to lack of preservation and storage facilities. Osmotic dehydration is an operation used for the partial removal of water from plant tissues by immersion in an osmotic solution. This is a useful technique to extend the shelf life and decrease the energy cost. It also helps to improve the s...
