Drying of vegetables in Egypt

Ali, H.M. et al. [1982]

A solar dryer was used to dry Jew's mallow (Corchorus olitorius L.) and okra (Hibiscus esculentus L.). The drying procedure depends on using heated air of 60 degrees celius on average. The results revealed that the rate of drying was high in the first 3 hours and then slowed down during the remainder of the drying time. The duration of drying for both Jew's mallow and okra was on average 22.5 ...

Vegetables were analyzed for vitamin C and carotene content. Four selected species were subjected to solar dehydration with and without photoprotection. Two pretreatments, steam blanching and sulfiting, were applied and carotene retention in the resulting dried products was evaluated. A control study was conducted with ambient temperature shade dried material subjected to the same pretreatment ...
