Effect of Chemical Additives on the Shelf Life of Cucumber Juice
نویسندگان
چکیده
Cucumber (Cucumis sativus L.) is a commercially cultivated worldwide as a seasonal vegetable crop. The aim of the experiment was to compare the effect of different chemical additives namely Sodium benzoate, Potassium metabisulfite( KMS) and their combination, on the physicochemical and phytochemical parameters and antioxidant activity of cucumber juice. The storage was done for 6 months at room temperature and the analysis was conducted at the interval of one month. For the physicochemical parameters like TS, TSS, acidity, color values (Lab), a very slight but non-significant change was observed. Vitamin C, total phenols and antioxidant activity changed significantly (p≤0.05). The variation was found in the color of different samples. Considering all the parameters, samples treated with potassium metabisulfite maintained the maximum nutrient stability.
