Vesicle formation in the membrane of onion cells (Allium cepa) during rapid osmotic dehydration.
BACKGROUND AND AIMS Optimization of osmotic dehydration in different plant cells has been investigated through the variation of parameters such as the nature of the sugar used, the concentration of osmotic solutions and the processing time. In micro-organisms such as the yeast, Saccharomyces cerevisiae, the exposure of a cell to a slow increase in osmotic pressure preserves cell viability after...
متن کاملEffect of process parameters on the effectiveness of osmotic dehydration of summer onion
The present study was carried out to investigate the effects of solution concentration, immersion time and temperature on the osmotic dehydration (OD) of summer onion. OD was done using sucrose, salt and combined (sucrose-salt) solution. In this study three sucrose (40,50 and 60%), five salt (5,10,15,20 and 25%) and five sucrosesalt (combine) solution (40:15, 45:15, 45:20 50:15 and 55:15 %) wer...
متن کاملDevelopments 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 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...
متن کاملOnion, a Potent Inhibitor of Xantine Oxidase
Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...
