Abstract

This research work was conducted to study the effect of sucrose solution with different chemical preservatives on overall quality of the strawberry fruit kept at ambient temperature. The treatments were : S0 (Control), S1 (Strawberry fruit + sucrose solution (30o brix) + Sodium benzoate 0.1%), S2 (Strawberry fruit + sucrose solution (30o brix) + Potassium sorbate 0.1%), S3 (Strawberry fruit + sucrose solution (40o brix) + Sodium benzoate 0.1%), S4 (Strawberry fruit + sucrose solution (40o brix) + Potassium sorbate 0.1%), S5 (Strawberry fruit + sucrose solution (30o brix) + Sodium benzoate 0.05% + Potassium sorbate 0.05%), S6 (Strawberry fruit + sucrose solution (40o brix) + Sodium benzoate 0.05% + Potassium sorbate 0.05%). All these treatments were examined physicochemically (Titratable acidity, pH, ascorbic acid, TSS, reducing and non-reducing sugar) and organoleptically (Texture, flavor, color and overall acceptability) at each 15 days interval for three months. Storage results shown that Decreased was found in pH from (3.49 to 3.32), ascorbic acid from (54.82 to 30.08 mg/100 g), non-reducing sugar from (20.41 to 13.36%), color score from (9 to 4.96), texture score from (9 to 5.14), flavor score from (9 to 5.23) and overall acceptability score from (9 to 5.40) while increased were found in TSS from (17.17 to 21.01oBrix), titratable acidity from (0.38 to 0.53%) and reducing sugar from (8.35 to 11.16%) throughout storage period. The highest mean value for pH was occurred in treatment S1 (3.45), titratable acidity in S3 (0.50%), TSS in S6 (24.76oBrix), ascorbic acid in S5 (46.30mg/100g), reducing sugar in S6 (11.69%), non-reducing sugar in S1 (19.65%), color in S5 (7.60), texture in S1 and S5 (7.46), flavor in S3 and S5 (7.60) and overall acceptability in S2 (7.83). Statistical results revealed that treatment S5 followed by S1 were found adequate both physicochemically and organoleptically.
