Samples of juice from both early and later season New Zealand grapefruit have been analysed for the presence of three enzymes that have been reported in some overseas citrus varieties. While both early and late season juice contained pectinesterase, neither polygalacturonase nor ascorbic acid oxidase was detected in juice extracted from early or late season fruit.
