Abstract

The effect of different pre storage treatments (Arabic gum and potassium silicate combined with modified atmosphere packing (MAP) on polyethylene bags at 40 or 80 mu and heat shrinkable) on berries quality and extending the storage life of Early sweet grape under two different storage temperature (0 and 7 ± 1oC) have been investigated. Results clearly indicated that, potassium silicate and Arabic gum with heat shrinkable under temperature (0 ± 1 oC ) maintaining the discarded berries, reduced weight loss throughout,  reducing respiration rate and total acidity and recorded the high values of soluble solids contain and sensory evaluation of samples, flowed by the same substance with polyethylene bag at 40 mu which give moderate values while the least significant was obtained by wrapped fruit with polyethylene bags at 80 mu were given a value near untreated clusters (control).
