Details are given of the method used for pectolytic enzyme activity determination in Jonathan apples and 11 other fruits and vegetables. Pectinmethylesterase (PME) activity decreased substantially in apple extract stored at 5 deg C whereas polygalacturonase (PG) activity increased. Both PME and PG activities increased in apple and other fruits and vegetables during ripening.
