Abstract: The effects of sodium benzoate in chilling storage on tomato juice were studied. For the control the soluble solidsand reducing sugars decreased 20% and 60% respectively , and alcoholic flavour produced seriously after eight weeks storage.By adding 0.09% sodium benzoate the soluble solids and flavour of samples remained constant and reducing sugars decreasedabout 35% . Vitamin C and total colonies in all samples decreased during the storage, but the total colonies in the samples treatedwith sodium benzoate decreased much more. Hence adding 0.06%~0.09% potassium sorbate was suitable in the chilling storageof tomato juice .

Key words: tomato juice, storage, sodium benzoate, citric acid
