The effect of postharvest treatments i.e. chitosan at 2%, citric acid 0.5% and malic acid 150 ppm as well as their combinations on some fruit quality parameters during cold storage at 5°C. 90-95% relative humidity, to assess the effect of treatments on weight loss %, decay, fruit firmness (Ib/inch2), juice TSS %, juice acidity % and respiration rate.
