Food Science (MS) Theses
The goal of this research was to determine the effect of irradiation on post-harvest disorders and ripening quality of ‘Bartlett’ pears stored for 3 months in air. ‘Bartlett’ pears were treated at 470 and 940 Gy and held at -1 - 0 ˚C at 95 % humidity. At 0, 45, and 90 days following treatment, the pears were brought to room temperature and allowed to ripen. The pears were then monitored for changes in respiration rate and ethylene production. After reaching the climacteric peak, pears were evaluated for incidence of post-harvest disorders, ACS and ACO enzyme activities, and quality factors …
