Program Areas — Dr. Randy Beaudry, Professor

Fruit - Pomology

• Modeling respiration of apple slices in modified-atmosphere packages
• Inhibition of fungal activity and enhancement of aroma biosynthesis in apple slices
• Changes in chlorophyll flurorescence of apple fruit during maturation, ripening and senescence
• Respiratory and fermentative metabolisms in asparagus tips under low O2/High CO2 atmosphere
• Regulation of the steady state oxogen in asparagus spears tips: responses of glycolytic metabolism and sucrose-metabolizing enzymes under low oxogen/high carbon dioxide atmospheres
• Phosphate and nucleotide metabolism under low O2 and high CO2 partial pressures in the tips of harvested asparagus spears stored at 1 degree Celsius
• Aroma biology and biochemistry

Post-harvest

Dr Beaudry's research activities focus on preserving the postharvest quality of fruits and vegetables. Specific areas of expertise include modified atmosphere packaging, controlled-atmosphere storage, non-destructive quality assessment, flavor analysis, apple scald physiology and use of volatiles to inhibit decay. Spinoffs from research have lead to the development of a number of practical devices or methods for which patent applications have been submitted.
