SANTAMARIA BASULTO, Felipe et al. Postharvest ripening and maturity indices for maradol papaya. INCI [online]. 2009, vol.34, n.8, pp.583-588. ISSN 0378-1844.

Fruit ripening in papaya Carica papaya cultivars varies widely in terms of skin color changes, pulp firmness and shelf life. Most papaya ripening studies have been done using ‘Solo’ varieties. No objective maturity indices have been developed for Maradol papaya, and studies describing color changes during fruit ripening only cover the initial and final maturity stages. Changes in the main quality attributes of Maradol papaya were documented during the ripening process to identify maturity stages and define objective maturity indices to be applied as harvest indices and quality standards. Six maturity stages were identified and quality attribute value ranges proposed as quality standards. Skin color can be considered an appropriate maturity index, b* values are good indicators for early maturity stages, while a* value are better for late stages.
