source Change of shell color from green to yellow at the base of the fruit. Pineapples are non-climacteric fruits and should be harvested when ready to eat. A minimum soluble solids content of 12% and a maximum acidity of 1% will assure minimum flavor acceptability by most consumers.

- Uniformity of size and shape
- Firmness
- Freedom from decay
- Freedom from sunburn, sunscald, cracks, bruising, internal breakdown, endogenous brown spot, gummosis, and insect damage.
- Tops (crown leaves): green color, medium length, and straightness.
- Range of soluble solids = 11-18%; titratable acidity (mainly citric acid) = 0.5-1.6%; and ascorbic acid = 20-65 mg/100g fresh weight, depending on cultivar and ripeness stage

follow Exposure of pineapples to ethylene may result in slightly faster degreening (loss of chlorophyll) without influencing internal quality. Pineapples must be picked when ripe because they do not continue to ripen after harvest.

- 3-5% O2 and 5-8% CO2
- Benefits of CA include delayed senescence and reduced respiration rate Atmospheres (CA)
- Postharvest life potential: 2-4 weeks in air and 4-6 weeks in CA 10°C (50°F), depending on cultivar and ripeness stage
- Exposure to O2 levels below 2% and/or CO2 levels above 10% should be avoided because of the potential for development of off-flavors.
- Waxing may be used to modify O2 and CO2 concentrations within the fruit enough to reduce incidence and severity of endogenous brown spot.
