Gamma And X-Ray Irradiation Improve Postharvest Shelf-Life In 'Bartlett' Pears, Matthew Garcia
Gamma And X-Ray Irradiation Improve Postharvest Shelf-Life In 'Bartlett' Pears, Matthew Garcia
Food Science (MS) Theses
The objective of this study was to investigate the effects of gamma and x-ray treatment on ‘Bartlett’ pear physiology during postharvest storage. Freshly harvested ‘Bartlett’ pears were irradiated with gamma irradiation at 0.412 and 0.819 kGy and x-ray irradiation at 1.03 and 1.94 kGy, then stored at 0-1 ⁰C and 95% relative humidity. The pears were removed from cold storage at 45 and 75 days and allowed to ripen at room temperature for four and two days, respectively. Respiration rate and ethylene production were measured during fruit ripening. Color, firmness, titratable acidity, soluble solids contents, and occurrence of superficial scald …

Impact Of Gamma Irradiation On Post-Harvest Disorders In 'Bartlett' Pears, Michelle Tu
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 …
