GUTIERREZ GUZMAN, Nelson; DUSSAN SARRIA, Saul  e  CASTRO CAMACHO, Jennifer. Postharvest Physiology and Quality Attributes in Guava "pear" (Psidium guajava cv.). rev.ing. [online]. 2012, n.37, pp.26-30. ISSN 0121-4993.

The objective of this study was to evaluate the maturity physiology in pear guava fruits (Psidium guajava cv.) harvested in the north of the Huila department in Colombia at three different stages of maturation, and under two storage conditions. The maturity fruit indices were assessed until the fruit reached consumption maturity. The weight losses described a linear model and the firmness showed a logarithmic model, the total soluble solids content (TSS) increased, whereas citric acid contents decreased; the respiratory rate under ambient conditions ranged from 60 to 100 mL CO₂ • kg^-1 • h^-1 and the climacteric crisis began at 50 hours whereas under refrigerated storage between 75- 90 hours producing between 15 y 20 mL CO₂ • kg^-1 • h^-1.
