Packaging Systems - Research & Evaluation
Various packaging systems and their effects on the quality of fruit and vegetable products are studied. Experienced with MAP, hot fill pouch technologies and rigid containers (plastic, glass and cans).
Package Integrity/Failure Evaluation
- Glass failure determination via container reconstruction
- Can seam inspection and testing
- Shelf life studies
- Headspace testing
- SQC technique instruction
- Product - film interaction studies
Modified Atmosphere Packaging
Modified atmosphere packaging studies are conducted with fruit and vegetable products to match tissue responses to changes in temperature and gas composition with permeability characteristics of packaging materials. Steady state and transient gas compositions in produce packages are calculated using specially developed computer programs.
Time-Dependent Gas Concentration Profiles
Measurement of Quality Changes
Many techniques are used to monitor quality changes in packaged products. Chemical analysis, physical property measurements and microbiological tests are employed to study package - product interactions.
Change in Hunter L value (Lightness) over time for five containers - 4 polymeric films and glass.
