Influence of pre-treatment on the drying process of apricots
ABSTRACT- Drying has been used for the preservation of fruits since ancient times. Dried apricot reduces the damages, weight and volume losses, packaging space, storage and handling costs. In this paper, the effects of hot air dryer on an Iranian apricot cultivar ”Noori” have been investigated. The experiment was conducted at three temperatures (30, 40 and 50oC), three fruit thicknesses (5, 10 ...
متن کاملModeling 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...
متن کاملEffect 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...
متن کاملInfluence of Freeze-Drying and Oven-Drying Post Blanching on the Nutrient Composition of the Edible Insect Ruspolia differens
The longhorn grasshopper, Ruspolia differens (Serville), plays an important role as a food source across Sub-Saharan Africa, where it is consumed as a delicacy in both rural and urban areas. The effect of two drying methods (freeze-drying and oven-drying), employed after blanching, on the proximate, fatty acid and mineral composition of the two most common morphs was determined. Ruspolia differ...
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...
