| Abstract | ||||
| The drying characteristics of apricot were determined using Open Sun and three Greenhouse Drying (Black Mesh Shading, white and black poly film plastic in as absorbers plate covering greenhouse. pretreatments (control, sucrose syrup and Sodium bicarbonate) were used before drying conditions at ( Open air , White and Black poly film plastic greenhouse and Black Mesh Shading). total soluble sugar and moisture content were also measured for the different fresh and dried apricot. The fresh apricot fruit initial moisture content was 80.03% d.b. Results showed that the moisture content and total soluble sugar were highest in sodium bicarbonate blanched sample, immediately after dehydration. Under using Black polyethylene greenhouse dryer for untreated apricot, the drying time was 660 min. where losses in moisture content decreased from 79.25 at 60 min to 26.5 % at 660 min. The maximum value of Total soluble sugar in Black poly film plastic greenhouse was 0.417 mg/ml for treated by Sodium bicarbonate while the minimum value was 0.173 mg/ml for un-treated apricot, in White poly film plastic greenhouse | ||||
