  Benzoate and Potassium sorbate separately and in combination with different concentration is used for the preservation of pear nectar. The samples were packed in 250 ml transparent plastic bottles at room temperature for a storage period of 90 days. The treatments were P0 (pear nectar with no preservative), P1 (pear nectar+0.1% Sodium benzoate), P2 (pear nectar+0.1% potassium sorbate), P3 (pear nectar+0.05% Sodium benzoate), P4 (pear nectar+ 0.05% Potassium benzoate) and P5 (pear nectar+0.05% Sodium benzoate and 0.05% Potassium sorbate). Samples of pear nectar were evaluated for total soluble solids, ascorbic acid, %acidity, pH, reducing and non-reducing sugar and sensory evaluation (color, flavor, taste and overall acceptability). pH decrease from 4.03 to 3.60, total soluble solids increase (14.90 ..
