Osmotic dehydration combined with hot air convective drying of Aloe vera (Aloe barbadensis Miller) gel
Aloe vera gel is widely used as a functional ingredient in food processing. This gel is very unstable due to its high water activity. Drying process can be used to obtain shelf stable products. Response surface methodology was used to assess the effects of solution concentration (30-60% w/w), solution temperature (30-50°C) and immersion time (4-6h) at atmospheric pressure and constant solution ...
متن کاملOptimization of osmotic dehydration of papaya followed by air-drying
Papayas are a fragile fruit; characteristic that limits large-scale exportation from the producing centers to countries in temperate regions. Loss of fruit ranges from 10% to 40% and could be reduced if papayas were dried. The process of osmotic dehydration followed by air-drying was studied and modeled for papaya preservation, so it could be optimized. The developed model has been validated wi...
متن کاملModeling Wound-induced Respiration of Fresh-cut Carrots (Daucus carota L.)
A mechanistic model based on synthesis and inactivation of enzymes, associated to the respiration pathway, was proposed to describe wound-induced respiration of fresh-cut produce. Carrots (Daucus carota L.) were cut into slices, sticks, a combination of both, and shreds to obtain different wounding intensities, defined by the ratio of new area created to tissue weight (A/W). Respiration rates o...
متن کاملThe 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...
متن کاملstudying drying kinetics of button mushroom pretreated by osmotic dehydration
dehydration is one of the most common preservation methods for button mushroom. dried mushroom slice and powder is used in formulation of soups and sauces. in this study, the effect of osmotic pretreatment on drying kinetics of button mushrooms was studied. thin slices of mushroom were immersed in osmotic solution containing 5% sodium chloride and 0.5% calcium chloride at a temperature 40 °c fo...
