Fresh Whole and Prepared Fruit and Vegetable Products

The principal spoilage mechanisms affecting whole and prepared fresh fruit and vegetable products are microbial growth, enzymic browning, and moisture loss.

MAP which results in depleted O2 and/or enriched CO2 levels is very effective at inhibiting these spoilage mechanisms, as well as:

 

  reducing respiration
 delaying ripening
  decreasing ethylene production and sensitivity
 retarding textural softening
 reducing chlorophyll degradation
  alleviating physiological disorders

Unlike other chilled perishable foods that are MA packed, fresh fruit and vegetables continue to respire after harvesting and any subsequent packaging must take this into account. The products of aerobic respiration are CO2 and water vapour (whereas fermentation products such as ethanol, acetaldehyde and organic acids are produced during anaerobic respiration). Respiration is affected by numerous intrinsic properties of fresh produce as well as various extrinsic factors but, generally speaking, the Achievable shelf-life of MA packed produce is inversely proportional to respiration rate. The depletion of O2 and enrichment of CO2 are natural consequences of the process of respiration when fresh fruit or vegetables are stored in an hermetically-sealed package. Such modification of the atmospheric composition results in a decrease in the respiration rate of plant material. If produce is sealed in an impermeable film, inpack O2 levels will fall to very low concentrations where anaerobic respiration will be initiated. Anaerobiosis is usually associated with undesirable odours and flavours and a marked deterioration in product quality.

* The Food Safety (Temperature Control) regulations 1995 states that the maximum Storage temperature for chilled perishable foods is 8°C. There will be flexibility to vary this when scientifically justified. For legal temperature storage requirements, please contact the Campden and Chorleywood Food Research Association.
