“…These were made into film packs containing three loadings of asparagus. The loads were chosen using data on asparagus respiration in response to atmospheres (Brash et al, 1995;Bycroft, unpublished) to estimate an ideal load, then a high and a low load were selected (Table 1). The calculations were based on a simple model for modified atmosphere packaging at constant temperature (Zagory & Kader, 1988).…”

Asparagus spears held in warm conditions (20ЊC) for 4 days in controlled atmospheres (CA) ranging from 5 to 10% oxygen with 5-15% carbon dioxide had significantly longer residual shelf-life (Ϸ4.5 days) in air than did check spears (2.6 days). This response was also reflected in sensory characteristics, with lower off-flavour ratings and higher flavour and acceptability ratings for CA-treated than for check spears. The level of response was similar across the range of atmospheres tested. Tests using plastic films differing in permeability demonstrated that modified atmosphere technology can be used to obtain the improvement in spear quality, but the gas permeability of the films tested was too low to provide a commercially useful pack. The potential for microperforated films for this application is discussed.

“…Also, deterioration of asparagus spears appeared to be strongly related to its own metabolic rate (Brash et al, 1995). suggested using metabolic rate as a rate index for quality changes and Hertog et al (1999) applied this approach to explain the effects of MA on spoilage of strawberries.…”

Gas exchange rates and quality changes of avocados (Persea americana , Mill., cv. 'Hass') stored at 7 8C in 32 different modified atmosphere (MA) conditions generated using a flow-through system, were monitored to characterise their functional relationship. An integrated modelling approach was used to link rates of quality loss to the rate of gas exchange. This revealed a close quantitative relationship between the gas exchange of 'Hass' avocado fruit on one hand and weight loss, colour change and softening on the other, indicating a direct metabolical link between these processes. High CO 2 lowered the respiratory quotient of avocado, an effect which, based on literature, could be explained by a shift from oxidative phosphorylation into the alternative respiratory pathway. In the model approach, the rates of quality degrading processes were linked to oxidative phosphorylation only, assuming this is where ATP was being produced. At high CO 2 levels at aerobic conditions, unaccounted weight loss data indicated a considerable volatile production which, however, was not qualitatively characterised. Both weight loss and colour change indicated the involvement of anaerobic processes at low O 2 levels. At 2 kPa O 2 and 0 kPa CO 2 no CO 2 injury occurred, while the change in hue was minimal, weight loss was minimised, and softening was almost completely inhibited. At such low O 2 levels, no additional benefit was found from raising the levels of CO 2 .

“…Given the importance that environmental parameters have in keeping of product quality level during postharvest phases, they have gained the attention of researchers. Brash, Charles, Wright, and Bycroft (1995), for example studied the relation between the respiration rate expressed in terms of CO 2 emissions of a product stored at fixed temperature and its quality in terms of Shelf Life (SL) of asparagus; Zheng and Wolff (2000), focused on the relation between remaining quality, expressed in terms of product deterioration rate, and ethylene production in some varieties of melon. They showed a linear relation between the ethylene emission and the postharvest decay rating assessed through a visual inspection of products.…”
