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.

Sequential decreases or increases in the levels of O2 in controlled atmosphere (CA) were investigated as techniques to improve fruit quality of `McIntosh' apples (Malus ×sylvestris [L.] Mill. var. domestica [Borkh.] Mansf.), a cultivar that tends to soften rapidly in storage. Precooled fruit that were harvested at optimum maturity for long-term storage were placed immediately in different programmed CA regimes. In the first year, CA programs consisted of 1) `standard' CA (SCA; 2.5–3.0% O2 + 2.5% CO2 for the first 30 d, 4.5% CO2 thereafter) at 3 °C for 180 d; 2) low CO2 SCA (2.5–3.0% O2 + 2.5% CO2) at 3 °C for 60 d, transferred to low O2 (LO; 1.5% O2 + 1.5% CO2) at 0 or 3 °C for 60 d, and then to ultralow O2 (ULO; 0.7% O2 + 1.0% CO2) at 0 or 3 °C for 60 d; and 3) ULO at 3 °C for 60 d, transferred to LO at 0 or 3 °C for 60 d, and then to SCA or low CO2 SCA at 0 or 3 °C for 60 d. In the second year, the regimes sequentially decreasing in O2 were compared with continuous ULO and SCA. After removal from storage, apples were held in ambient air at 20 °C for a 1-week ripening period. Fruit firmness was evaluated after 1 and 7 d at 20 °C, whereas the incidence of physiological disorders was assessed only after 7 d. Lowering the temperature while decreasing O2 was the best CA program with significant increased firmness retention during storage and after the 1-week ripening period. Reduced incidence of low O2 injury in decreasing O2 programs and absence of core browning at the lower temperature were also observed.

ABSTRACT Controlled atmosphere storage allows for the long-term and short-term storage of fruit without a significant decrease in quality, resulting in a longer shelflife of fresh fruit. The Department of Horticulture at the West Pomeranian University of Technology in Szczecin conducted research on the effects of post-harvest precooling (3-4°C within two hours) and storage conditions (conventional cold room and controlled atmosphere storage) on fruit firmness, chemical composition, colour and weight loss. After six weeks of storage, it was found that the quality of fruit had declined. In comparison with fresh fruit, the harvest was found to have lost weight and darkened in colour. In addition, a decrease in firmness and the content of ascorbic acid and polyphenolic compounds was also observed. The fruits that were stored in a cold room with a controlled atmosphere and rapidly chilled immediately after harvest were the least affected. In addition, the research showed that there was a high correlation between the anthocyanin index and the polyphenol content in the fruits. To maintain the high quality of the fruit, the fruit must be very rapidly cooled soon after harvest and stored under optimal conditions - a cold room with a controlled atmosphere.

`Ginger Gold' is a high-quality summer apple with potential for processing and fresh markets. Although summer cultivars typically exhibit poor storage quality, data from three seasons indicate that storage potential is high for `Ginger Gold' in low-O2 controlled atmosphere storage. In 1995, fruit harvested 25 Aug. (85N) were stored in air (0 °C), 3% O2/<2% CO2 (0 °C) or 0.7% O2/1% CO2 (0 °C) for 4 or 7 months. After 4 months, firmness of fruit stored in air, 3% O2 and 0.7% O2 were 53N, 67N, and 80N, respectively. After 7 months, apples stored in air were soft (45N) and had excessive decay (55%), cracking (48%), and breakdown (61%). However, fruit stored in 0.7% O2 were of good quality (76N, 4% decay, 4% cracking, and no breakdown). No low-oxygen injury occurred. Apples were harvested on 14, 21 and 28 Aug. 1996 (85N, 80N, and 76N, respectively) and stored in air (0(C), 1.5% O2/1% CO2 (0(C), 1% O2/1% CO2 (0 °C) or 0.7% O2/1% CO2 (0 °C). Soluble solids were (9.5 at harvest, with starch scores of 3.5–4.5. After 2 months in air the firmness began to decrease rapidly and after 4 months ranged from 49–62N. Apples stored for 4 months in CA (≤1% O2) maintained firmness >70N. In 1997, fruit were harvested 14, 21, 28 Aug. and 4 Sept. (102, 96, 89, and 82N, respectively and 12–13.3 °Brix). After 4 months in CA, fruit were still of high quality (>83N, > 13.2 °Brix).

Long term storage of a variety of crops as well as long-distance transport, has allowed meeting the consumers' expectations in the supply of many types of fresh fruits and vegetables throughout the year. This is only possible with the use of several postharvest technologies. This chapter starts with a brief historical context followed by an overview of the technologies used for fruits and vegetables storage, including refrigerated and controlled atmosphere (CA) storage as well as the most recently developed technologies for storing these produces. We also address the innovation requirements in the refrigeration systems when integrating cold storage with CA, including the need for higher refrigeration capacity, use of air tight storage chambers, CO2 scrubbers and atmosphere generators. The effects of these methodologies on fruit physiology and quality during storage are further discussed. Finally, the current recommendations for long term storage using ‘Rocha' pear as a case study are presented.
