Abstract:
... The objective of this research was to determine the nature and extent of CO2 injury in apples treated with 1-methylcyclopropene (1-MCP) and stored in controlled atmosphere (CA). ‘McIntosh’ apples were treated immediately after harvest with 0, 60, 300, or 600 nL·L-1 of 1-MCP for 18 to 24 hours at ~20°C, and then placed in CA (3% O2 + 2.5% CCO2 for the first 30 days followed by 3% O2 + 4.5% CO2 ther ...

mechanism of action; 1-methylcyclopropene; diphenylamine; ethylene; apples; texture; total soluble solids; controlled atmosphere storage; modified atmosphere packaging; storage time; pears; ripening; malic acid; cold storage
Abstract:
... 1-Methylcyclopropene (1-MCP), also known as SmartFresh™ (0.14%), blocks ethylene action in harvested fruit. 1-MCP’s mode of action is via a preferential attachment to the ethylene receptor, thereby blocking the effects of both endogenous and exogenous ethylene. This study determined the potential of 1-MCP as an alternative to modified atmosphere (MA) and controlled atmosphere (CA) storage of apple ...

A new internal browning disorder observed in ‘Pacific Rose’ apples stored in New Zealand coolstores in 1999 is characterised by randomly distributed patches of brown flesh between the locules of the core area out into the cortex. Data obtained from a large coolstore operation in Hawkes Bay, New Zealand showed that 6% of 180 lines assessed at the end of regular air storage exhibited the disorder wh ...

Abstract:
... Storage of pears under low oxygen levels (0.5-1.0 kPa) leads to decreased ascorbic acid and ATP levels, a lower ATP-production, and to internal browning, a storage disorder in pears. Addition of 5 kPa carbon dioxide to the storage atmosphere increased the severity of this disorder. Experiments showed that anoxia can result in off-flavours, but not in internal browning. Internal browning is caused ...

Abstract:
... Different possibilities (combination of gas composition and packaging film) of consumer-size modified atmosphere packages for highly perishable strawberries and raspberries, stored at 7°C, were evaluated. All proposed closed packaging systems resulted in a prolonged shelf life compared to the nowadays applied macro-perforated packaging films. A selective permeable film was selected based on the re ...

Abstract:
... Based on the colour development of tomatoes (theoretical) and apples (measured) as an example the approach to biological variance from a new perspective is made more clear and more explicit. The origin of biological variance is traced back to the stage of maturity at the moment of harvest. By modelling the colour development of individual units in a batch in a generic fashion, and using this model ...

Abstract:
... The food that we eat is uniform neither in shape or appearance nor in internal composition or content. Since technology became increasingly important, the presence of biological variance in our food became more and more of a nuisance. Techniques and procedures (statistical, technical) were developed. The most widely used are sorting or grading on large-scale operations. Statistical rules were deve ...

Abstract:
... New economics in this paper stands for the shift in paradigm from a supply-oriented economy in a business complex in which the demand side is determining the development. More demanding consumers forced agribusiness to improve the processes. This requires a more intensive coordination of the processes in the supply chain. Therefor the organization and interaction in the food supply chain is in con ...

Abstract:
... Air movement initiated by evaporator fans is generally considered to flow over and around fruit bins and through the runner spaces. Direct measurement of airflow velocities and patterns in fruit storage rooms is extremely difficult because flow is highly turbulent in some areas and uniform in others. Recent developments in Computational Fluid Dynamics (CFD) simulations have provided a valuable too ...
