“…Moreover, the critical ethanol level of 200 mg/100 mL of juice, which has been associated to build-up of off-flavors in citrus fruit (Ke and Kader, 1990;Hagenmaier, 2002), was not exceeded. These results are in agreement with those of other authors working with different mandarin cultivars (Abdellaoui et al, 1995;Miller et al, 2000;Mahrouz et al, 2002;Ladaniya et al, 2003;Alonso et al, 2004Alonso et al, , 2007. Nevertheless, volatile synthesis in response to irradiation has been found to be cultivar-dependent (Miller et al, 2000) and in some cases irradiation can lead to unacceptable contents.…”

“…In a study on the effects of γ-rays at doses ranging from 150 to 450 Gy on the quality attributes of selected mandarin cultivars, Miller et al (2000) found a wide range of tolerance to irradiation damage (from 1.7 to 100% peel pitting in 'Minneola' and 'Sunburst' mandarins, respectively). Ladaniya et al (2003) observed no rind disorders in 'Nagpur' mandarins after γ-irradiation at 1,500 Gy. In contrast, unacceptable damage on 'Fortune' mandarins was noticed after electron irradiation at 1,000 Gy (Alonso et al, 2002).…”

In the present work, survival of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) on artificially infested 'Clemenules' clementine mandarins (Citrus reticulata Blanco) was assessed on fruit subjected to integrated quarantine treatments consisting of irradiation with X-rays at doses of 0 (control), 30, 54, and 164 Gy followed by exposure to 1°C for 0 (control), 3, 6, 9, or 12 days. Additionally, physico-chemical (rind color, firmness, and physiological disorders, soluble solids concentration, titratable acidity, maturity index, juice yield, and ethanol and acetaldehyde content) and sensory (sweetness, acidity, sensory maturity index, off-flavors, and mandarin-like flavor) fruit quality of 'Clemenules' clementines were assessed on X-irradiated fruit exposed to 1°C for 0 (control), 6, or 12 days. Complete insect mortality with no negative effects on fruit quality after 7 days at 20°C of shelf life was obtained on clementines firstly X-irradiated at 30 Gy and subsequently exposed to 1°C for 2 days. This combination of treatments considerably reduced quarantine time if compared to standard cold quarantine treatments (1.1-2.2°C for 14-18 days) and therefore showed promise as a potential commercial treatment for Spanish citrus exports.Additional key words: Ceratitis capitata, citrus disinfestation, clementines, fruit quality, integrated quarantine treatments, sensory analysis, X-irradiation. ResumenCombinación en poscosecha de rayos X y frío para el tratamiento cuarentenario de mandarinas 'Clemenules' contra la mosca mediterránea de la fruta En este trabajo se evaluó la supervivencia de la mosca mediterránea de la fruta Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) en mandarinas clementinas 'Clemenules' (Citrus reticulata Blanco) infestadas artificialmente y sometidas a la combinación de tratamientos ionizantes con rayos X a dosis bajas (0, 30, 54 y 164 Gy) con exposiciones a frío de corta duración (1°C durante 0, 2, 4, 6, 8, 10 ó 12 días). Adicionalmente, se determinó la calidad físico-química (color, firmeza y alteraciones fisiológicas de la corteza, concentración de sólidos solubles, acidez total, índice de madurez, rendimiento en zumo y contenidos de etanol y acetaldehído) y sensorial [dulzor, acidez, índice de madurez sensorial, malos sabores y 'flavor' (sabor + aroma)] de clementinas 'Clemenules' tratadas con rayos X y expuestas a 1°C durante 0 (control), 6 ó 12 días. Con frutos irradiados a 30 Gy y expuestos a 1°C durante 2 días se obtuvo una mortalidad completa de C. capitata sin efectos negativos en la calidad del fruto medida después de un período de simulación de la comercialización de 7 días a 20°C. Por tanto, esta combinación de tratamientos redujo sensiblemente los tiempos de cuarentena necesarios con los tratamientos de frío estándar (1,1-2,2°C durante 14-18 días) y mostró buen potencial como tratamiento comercial para los cítricos españoles de exportación.Palabras clave adicionales: análisis sensorial, calidad de fruto, Ceratitis capitata, clementinas, de...

“…Irradiation increased (P < 0.05) the respiration rate (CO 2 production) (P < 0.05) of the broccoli. The same behavior was observed in other fresh produce undergoing irradiation treatment such as lettuce, citrus, mango, and blueberry (Han et al, 2004;Landaniya, Singh, & Wadhawan, 2003;Moreno et al, 2006aMoreno et al, , 2006bMoreno, Castell-Perez, Gomes, Da Silva, Kim, & Moreira, 2007; …”

“…Application of ionizing radiation for preservation of fruits and vegetables was suggested in the early 1990s and is effective in improving the shelf life of banana, mango, and papaya by delaying the process of ripening (Thomas 1986; Moy and Wong 1996). Of late, several researchers have demonstrated successful use of ionizing radiation in hygienization of minimally processed fresh produce without affecting the nutritional, textural, and sensory qualities (Niemira and others 2002; Ladaniya and others 2003; Mishra and others 2004; Dhokane and others 2006; Song and others 2007).…”

Radiation processing of minimally processed pineapple at a dose of 2 kGy was investigated. Effect of this treatment on different quality parameters like vitamin C content, total carotenoids content, sensory attributes, texture, and color was determined over a storage period of 12 d at 8 to 10 °C. Results showed that the irradiation treatment showed no significant effect (P > 0.05) on total vitamin C content of pineapple samples but a significant decrease (P≤ 0.05) in vitamin C during storage period in both controls as well as irradiated samples was observed. However, total carotenoids were not affected by irradiation and were stable during the whole storage period as well (P > 0.05). Sensory evaluation studies revealed that irradiation had no significant effect (P > 0.05) on the ratings of any of the sensory attributes of pineapple samples. Taste panelists could not differentiate between control and irradiated samples. Textural studies showed no significant effect (P > 0.05) of irradiation as well as storage period on the firmness of the central edible region of pineapple samples. Color attributes of both control and irradiated samples showed slight variation during the storage period of 12 d. However, irradiation at 2 kGy did not have a significant effect (P > 0.05) on all color coordinates. Thus, radiation processing with 2 kGy did not affect significantly the nutritional value as well as the sensory quality of minimally processed pineapple samples.
