Response of "Jonagold "apple to controlled atmosphere storage

This experiment was conducted at Kateholieke University of Leuven (Belgium) in order to determine the effect of controlled atmosphere storage on ethylene production and ripening of Jonagold apple during storage period. Apples were collected from commercial storage of Belgishe-Fruit-Veiling (B.F.V.) which had been under atmospheric controlled condition (1-2°C, 02 %1, CO2 %l.5 and C2H4, 500 to 80000 p.p.b.) during three times storage period (1st, 6th and 15th week). The analysis for each storage period was done on 1st and 7th days after storage for measuring of ethylene production, CO, production, flesh firmness and colour. With respect to statistical analysis, there was significant correlation between flesh firmness and ethylene production, flesh firmness was lower with increasing ethylene production. Ethylene production had no effect on CO, production. Results showed that loss of flesh firmness of apple during atmospheric controlled storage seems to be related to high ethylene concentration in storage rooms at first weeks of storage period. In conclusion loss of flesh firmness by the red side of apple was more than the green side during storage and shelf life period .
