dc.description.abstractHASTURK SAHIN, F., T. AKTAS, H. ORAK and P. ULGER, 2011. Influence of pretreatments and different drying methods on color parameters and lycopene content of dried tomato. Bulg. J. Agric. Sci.,17: 867-881 The effects of drying methods namely hot air drying (at 65, 75 and 85 degrees C drying temperatures and 1.5 and 2.5 m/s air velocity), vacuum drying, freeze drying and sun drying; and pretreatments namely dipping into 1% ascorbic acid + 1 % citric acid (EPSA) and dipping into 2 % sodium metabisulfite (EPSM) after 2% ethyl oleat + 4% potassium carbonate solution application on lycopene retention and color properties of dried tomato samples were investigated. Lycopene content values were determined by HPLC method and color parameters (L*a*b* and yellowness index) were measured directly a Hunter Lab chromatometer. a * / b *, b * L * / a *Delta L *, Delta a*, Delta b*, Delta C *, Delta E * values were calculated by using measured color characteristics. Effects of drying methods, pretreatments and interactions of pretreatments and drying methods on the lycopene values and color parameters were found significant as statistically. Maximum lycopene content was determined in freeze dried tomatoes and sun dried tomatoes followed these samples. Especially EPSA pretreatment increased the lycopene amount of dry tomato at the high temperature drying applications. In respect of color parameters, EPSM pretreatments the better results of L*, a* and b* values.
