| Abstract:
At-harvest fruit quality attributes of four feijoa (Feijoa sellowiana) cultivars (‘Unique’, ‘Triumph’, ‘Apollo’ and ‘Mammoth’) were measured during the 2002 season. Fruit were supplied ungraded and unsorted at optimum maturity as determined by ‘touch picking’ and were sourced from five production regions within New Zealand. The measured quality attributes were grouped into categories: (1) size and shape; (2) storage potential; (3) texture and taste; and (4) fruit maturity. Large variations between individual fruit and fruit batches were observed for most quality attributes. The ratio of the translucent part of the fruit section to overall cross-sectional area appeared to have utility as a measure of fruit maturity. Significant (P<0.05) between-batch differences in average water vapour permeance, titratable acidity, and brix to acid ratio showed potential to be linked in building an overall maturity index. Non-destructive fruit firmness may also be able to be used as a maturity indicator for grading and sorting fruit. | |
