EFFECT OF ETHYLENE CHEMISORPTION ON REFRIGERATED STRAWBERRY FRUIT |

| Abstract:
Treatment of strawberry cv. "Chandler", from Huelva region, by 3 g of a siliceous material (sepiolithe) impregnated with KMnO4 (commercially sold as "Green Keeper", in form of extruded round rods) per 500 g of berries, as ethylene absorbant, reduces the losses by fungal attack from 26.3 % to 10 % after 13 days at +2°C. Acid levels increased during fruit storage up to 8th day and then declined, and sugars were higher at the end of the storage period. Moreover, a firmness advantage was still evident in the fruits packed with the ethylene absorbant, for which the atmosphere into the bags had a higher CO2 concentration. These observed effects suggest that ethylene removal may be of commercial value for extending the storage life of refrigerated strawberries. | |
