This study examined the effects of freezing, storage, and cabinet drying on the anthocyanin content and antioxidant activity of blueberries (Vaccinium corymbosum L). Fresh samples were stored for two weeks at $\5^\circ$ C while frozen samples were kept for up to three months at $-20^\circ$ C. There were two drying treatments, one including osmotic pretreatment followed by cabinet drying and the...

This study was conducted to evaluate the effects of different levels of osmotic pretreatments prior to drying and different drying methods on nutritional quality of dried mushroom slices. The experiment consisted of sun, solar, and oven drying after dipping the slices in salt solutions of 5 and 10% concentrations for 50 minutes, the control being untreated mushroom sample. Significant differenc...

BACKGROUND Osmotic dehydration is a process of the partial removal of water which is based on immersion of material having cellular structure in a hypertonic solution. Osmotic dehydration is used as a pretreatment for the dehydration of foods before they are subjected to further processing such as freezing, freeze drying, vacuum drying. Management of spent syrup is one of the most important pro...

Amorphophallus paeoniifolius known as Elephant foot yam is a highly potential tropical tuber crop of Areace family. The tubers are rich in nutrients. It is a healthy low-fat food containing a good source of protein as well as starch. It is a natural product that is high in fiber, rich in potassium, calcium (50 mg g-1), phosphorus (34 mg g-1) vitamin A (260 IU g-1), vitamin B6, as well as with t...

Drying is one of the oldest methods for food preservation that removes water from fruit and makes it available consumption throughout year. Dried fruits can be produced by small- large-scale processors, which them a very popular among consumers manufacturers. The most frequent uses drying technology include osmotic dehydration, vacuum drying, freeze-drying different combinations other technolog...

in this study, mathematical modeling of hot air-drying of thin-layer papaya (carica papaya l.) slices with 5±1 mm thickness pretreated in osmotic solution (50% sucrose) was investigated. thin-layer drying was conducted under three different drying temperatures of 40, 50 and 60 °c at a constant air velocity of 0.9±0.1 m/s and absolute humidity of 0.6 ± 0.02 g of water/kg of dry air. it was found...

In this study, the effect of edible coat (carboxy methyl cellulose) before osmotic dehydration anddifferent drying methods on sensory and physical properties of dried apple (V. Golden delicious)rings was investigated. The coated and non-coated samples pretreated with 50% sucrose osmoticsolution and dried in freeze drier (-40 to -50°C, 0.026-0.017 mbar, 24 hr), vacuum drier (70°C, 200mbar, 8-10 ...
