Abstract
This research demonstrated the feasibility of incorporating modified atmosphere packaging (MAP) technology into existing mango export handling systems to better maintain the quality of fully mature mangos for the extended transit periods required for export from South America to consumers in the USA. Ataulfo, Tommy Atkins and Kent mangos were packaged in either Apio Breatheway MAP bags or NOW Plastics perforated bags (control) holding approximately 4 kg of fruit at a commercial mango packinghouse in Nayarit, Mexico.
The average initial maturity of the mangos was stage 3.0, 2.5, and 3.1 for Ataulfo, Tommy Atkins, and Kent (1-5 scale), respectively; the corresponding SSC readings were 11.4, 9.6, and 9.3%. The fruit were shipped in commercial truck shipments to an importer in Hidalgo, Texas and on to Gainesville, Florida (8-13°C) plus additional storage (12.5°C) at the University of Florida totaling 3 weeks to simulate long-distance shipping from South America to the USA. After 3 weeks, the atmospheres were: Ataulfo, 4.7% O2 + 13.1% CO2, Tommy Atkins, 3.6% O2 + 11.4% CO2, and Kent, 8.9% O2 + 9.0% CO2. The mangos of all three cultivars were maintained less ripe and with better quality in the MAP bags than in the perforated (control) bags as shown by flesh color and firmness, and SSC and TA measurements after 3 weeks of simulated shipping and after an additional 3 days at 20°C. This research also demonstrated in the Ataulfo shipment that MAP can prevent development of corte negro, a chilling-injury-related disorder.
