“…This browning incidence generally increased due to low energy production by fruit storage under low oxygen levels (Ho, Verboven, Verlinden, Schenk, Nicolaï, 2013). In 2012, fruits stored under CA showed the highest flesh breakdown, differing only from DCA-CF (Table 3).…”

The aim of the present work was to compare the effect of ultralow oxygen (ULO) with dynamic controlled atmosphere (DCA) and controlled atmosphere (CA) on the post storage quality of 'Royal Gala' and 'Galaxy' apples after long-term storage. Two experiments were carried out with 'Royal Gala' and 'Galaxy' apples, in the years 2012 and 2013, respectively. A higher internal ethylene concentration was observed in fruits stored under CA; intermediate concentration in fruits under ULO; and the lowest by fruits stored under DCA-CF (DCA based on chlorophyll fluorescence). Flesh firmness was higher in fruits stored under DCA-CF and ULO differing from CA, in the year 2012, but in 2013 fruits stored under ULO showed the highest flesh firmness, differing from CA fruits. DCA-CF is efficient in quality maintenance of 'Royal Gala' and 'Galaxy' apples. Both 'Gala' mutants stored under ULO show a similar quality maintenance to those stored under DCA-CF.

Nicolai  It has been demonstrated that fan and refrigeration cycling works to save energy. Load shifting of controlled atmosphere stores for saving energy costs seems worthwhile. AbstractEnergy cost concerns have led to question the temperature and air flow regimes in cool store facilities. In this paper, a CFD model of the air flow and temperature dynamics inside an apple fruit Page 1 of 33 1 cool store was developed, validated and used to analyse energy cost saving alternatives. Load shifting was attempted by cycling the temperature set point between 1.2 °C and 0.6 °C following a day/night regime. Discontinuous use of the cooling operation, including 12 h on / 12 h off; 10 h on / 14 h off; and 8 h on / 16 h off were also investigated. The study showed that the air circulation fan is the major source of heat load. Hence, an attempt to reduce energy cost should first deliberate on reducing the fan operation time. The study developed a generic tool to analyse temperature control options inside an apple cool store in response to energy use concerns.

The effects of several pre-and postharvest factors on apple cv. Braeburn browning disorder (BBD) incidence using a nine-factor experimental design has been investigated. The design allowed the determination of the effects of single factors as well as their interaction with growing season and storage time. BBD increased in severity with storage duration. BBD incidence was reduced with calcium and potassium fertilizers application, while it was increased when triazoles were used. Delayed controlled atmosphere (DCA) application resulted in less BBD in storage, while treatment with 1-methylcyclopropene (1-MCP) increased BBD incidence. More BBD was observed in fruit stored at above optimal CO 2 levels. BBD incidence was increased when O 2 concentration in CA was increased from 1 kPa to 3 kPa (optimum CA) or 6 kPa. Finally, the various factors showed a different effect for different growing seasons and storage time. These findings suggest a possible mechanism for the development of BBD. Further work should focus on extending the experimental design to include the interactions between the different pre-and postharvest factors.Keywords: Braeburn browning disorder; fertilizers; triazoles; controlled atmosphere; 1-methylcyclopropene Malus domestica Borkh., cv. Braeburn is a popular apple cultivar worldwide. To facilitate year-round availability of fruit, apples are stored at low temperature under controlled atmosphere (CA) conditions. Under the commercial storage conditions, apples can be stored well as a result of their reduced metabolic rate. The storability of cv. Braeburn is, however, limited by the development of internal browning (Elgar et al. 1999). Affected fruit show patches of brown tissue which can result in cavity formation (Elgar et al. 1998). The combination of brown flesh and off flavours makes brown apples unacceptable in the market, resulting in economic losses.Different apple varieties vary in their susceptibility to browning (Streif 2008). Cv. Braeburn has a high skin resistance (Rajapakse et al. 1990) turning the skin into a stronger diffusion barrier as compared to some other apple cultivars. Together with a dense cellular organization this results in relative high internal CO 2 concentration (Herremans et
