The object of research is the process convective and combined drying apple raw materials treated before dehydration in an ultrasonic bath. use pretreatment solves issue intensifying maintaining quality product. Sonication for 5 min reduces by 13.7 %, at 10 processing – 27.8 % compared to traditional drying. With increasing time 20 minutes, rate deteriorates. minutes under heating does not inten...

the aim of this study was to investigate the effect of ultrasound and drying pretreatments on apparent density as well as modeling apparent density during deep-fat frying of potato slices. ultrasound pretreatment was performed at 28 and 40 khz for 15 min and drying pretreatment were conducted at 80°c for 8 and 15 min. then, the frying process was done at 150, 170 and 190°c for 60, 120, 180 and ...

The article is devoted to the effect of pretreatment with a solution carrageenan on enzymatic activity cherry fruits in period storage. For purpose research between 2019-2020, Alpha and Pamiat Artemenko varieties same color were selected, sorted, washed, dried, covered that included (1−2 g/100 ml solution), glycerin (0.6 solution) according options: without treatment (control) treated solutions...

In the present study, the application of a BP neural network for prediction of the moisture content of barberry fruit (berberis vulgaris) during drying was investigated. The important parameters namely, pretreatment (heat shocking, olive oil + K2CO3 and NAT), air drying temperature (60, 70 and 80oC), air drying velocity (0.3, 0.5 and 1 m/s) and time (s) were considered as the input parameters a...

drying properties of high moisture potato slices with initial moisture content of about 4.06 (db) under thin layer fixed, semi fluidized and fluidized bed conditions were studied. drying air temperatures of 40, 50, 60 and 70°c were applied in experiments using a laboratory fluidized bed convective dryer. in order to predict the drying behavior of potato slices, seven thin layer drying models we...

On farm walnut drying is often a major bottle neck during the start of walnut harvest. The recommended maximum drying air temperature for English walnuts is 110 of. This limit is based on tests by university personnel during the introduction of heated air drying (Batchelor, 1924) which demonstrated that long term exposure to temperatures higher that 110°F caused walnuts to turn rancid. This pro...

An experiment was conducted to standardize the post harvest technology for Tinospora during the year 2006-07 at Medicinal Plants Unit, Horticultural College and Research Institute, TNAU, Coimbatore. The stems of 18 months old climbers were harvested and cut into pieces of different sizes (2.5, 5.0 and 7.5 cm) and subjected to sun drying in temperature ranging from 29 to 34°C during day time and...

Changes in vegetation and soil properties following permafrost degradation and thermokarst development in peatlands may cause changes in net carbon storage. To better understand these dynamics, we established three sites in Alaska that vary in permafrost regime, including a black spruce peat plateau forest with stable permafrost, an internal collapse scar bog formed as a result of thermokarst, ...

prove the dissolution property and oral bioavailability of poorly water-soluble drugs, solid dispersion methods have been extensively used and numerous approaches have been reported such as fusion, solvent evaporation, and spray-drying methods. However, these methods involve various problems. Solid dispersions prepared by fusion usually have the shortcoming of being tacky and unstable, and solv...
