Atmosphere Storage

A controlled atmosphere (CA) is an agricultural storage method. It is an atmosphere in which oxygen, carbon dioxide and nitrogen concentration as well as temperature and humidity are regulated. Glycolysis is the basis of both anaerobic respiration and aerobic respiration, and it occurs in nearly all organisms. It is regulated by three enzymes catalyzing nonequilibrium reactions: Hexokinase, phosphofructokinase, and pyruvate kinase.In this work we studied the effect of controlled atmosphere storage (CAS) of mango at 13°C on the activity of phosphofructokinase (PFK) and on fruit quality. This study was carried out on mango fruits (Mangifera indica L.) cv. Keitt. The storage of fruits under the CA retarded ripening and did not affect the quality attributes of Keitt mango. There was a significant decreasing in the activity of PFK as compared with control under (CAS) used in this work. These results indicate a potential for the application of CA for postharvest ripening control of mango. The optimal CA for long-term storage of "Keitt" mango at 13°C is (3% O2 +6% CO2+ 91% N2); under these conditions the storage life of mango can be extended up to 10 weeks.

Controlled-atmosphere storage had little effect on the quality of fruit of eight cultivars held under 2 kPa oxygen (O2) and 8 kPa carbon dioxide (CO2) versus ambient air. ‘Elliott’ fruit harvested from bushes with only 30% ripe fruit had significantly better storage quality than fruit picked later; however, there was no significant difference in the storage life of fruit that was stored fully blue versus partially green. Fruit from the first harvest of four cultivars had superior storage quality to that of the second. In one comparison of the long-term storability of nine cultivars, ‘Bluegold’, ‘Brigitta’, and ‘Legacy’ performed the best, storing for 4 to 7 weeks. In another postharvest trial of 17 cultivars, ‘Brigitta’ stored the longest (8 weeks) followed by ‘Aurora’ and ‘Draper’ (7 weeks). The most resistant genotypes to Alternaria spp. were ‘Brigitta’, ‘Aurora’, ‘Elliott’, and ‘Draper’, whereas the most resistant genotypes to Colletotrichum spp. were ‘Elliott’, ‘Brigitta’, ‘Toro’, ‘Draper’, and ‘Bluejay’.

We present a method for predicting firmness of `York Imperial' apples after air or controlled-atmosphere storage. Firmness and soluble solids content in freshly harvested fruit can be plotted on a graph showing a “decision line.” If the prestorage firmness and soluble solids coordinates for a given sample are above the decision line, then firmness after storage is predicted to be greater than the target value. Prestorage flesh firmness and soluble solids content were the best predictors of poststorage firmness. There was no significant improvement in firmness prediction when ethylene, starch, or other indicators of maturity were included.
