Abstract
Advances made in the past three decades in online grading are reviewed in context of fruit quality attributes.
Commercial sorting capability has expanded from weight to external colour and shape sorting and then to external defect recognition, while internal defect detection has been enabled through use of UV and particularly NIR wavelengths.
Disparities between commercial application and the scientific literature base are highlighted.
The potential for packhouse use of other non-invasive sensor technologies is summarised, primarily in context of at-line biosecurity applications.
The translation of technologies from packhouse to orchard is described in context of instrumentation for assessment of optimum harvest timing through assessment of fruit maturity, e.g., using hand-held spectroscopy, and harvest load, i.e., fruit size and number.
These technologies also provide a foundation for development of other capabilities in the orchard, including automated harvesting.
These topics will be illustrated with application examples from the Australian mango industry.
