“…Likewise, it has been shown that total soluble sugars and titratable acidity decreased in fruits of blueberry (Aurora, Elliot, and Liberty cultivars), reducing the fruit shelf life (Lobos et al 2014). Postharvest cold-storage also affects antioxidant compounds such as radical scavenging activity (RSA), total phenols, flavonoids, and anthocyanins (Connor et al 2002;Reque et al 2014;Zsivanovits and Iliev 2019). Lohachoompol et al (2004) reported that total anthocyanins decreased in blueberry fruits stored at 5°C for 2 weeks.…”

Highbush blueberry fruits are very perishable, decreasing quality and antioxidant potential during postharvest storage. Several preservation technologies to improve blueberries shelf life have been proposed. We evaluated the impact of fruit cold-storage and UV-C irradiation postharvest treatments on quality and antioxidant properties of berries from different blueberry cultivars grown in southern Chile. Berries of Legacy, Brigitta, and Bluegold cultivars were subjected to cold-storage (4°C, for 28 days) or UV-C irradiation (2.3 or 4.6 kJ m −2) before cold-storage (4°C) during 5 or 10 days. Then, fresh weight (FW), total soluble solids (TSS), titratable acidity (TiA), radical scavenging activity (RSA), total phenol content (TPC), and total anthocyanin content (TAC) were analyzed in whole fruits. During cold-storage, fruit FW was reduced (~20%) from day 7 onward, without variations among storage times. The irradiation of fruits with UV-C light also tends to reduce berry FW (~20%), but only in cultivar Legacy and in response to the highest UV-C doses. No significant differences were found in TSS or TiA of fruits by the effect of any treatments. Interestingly, UV-C irradiation induced greater antioxidant properties of blueberries. Bluegold and Brigitta fruits revealed increased RSA under 4.6 kJ m −2 doses. Also, Bluegold showed the highest levels of TPC at doses of 4.6 kJ m −2 of UV-C. Moreover, fruits of all cultivars exhibited increased TCA in response to the higher doses of UV-C. UV-C irradiation could be an interesting tool to improve antioxidant potential in highbush blueberries, which can negatively affect fruit quality for fresh consumption.

El arándano (Vaccinium sp.) es considerado un buen alimento debido a sus compuestos antioxidantes que le confieren múltiples beneficios a la salud del consumidor. Sin embargo, es susceptible al deterioro, por lo que se propone evaluar el efecto de las condiciones de acondicionamiento y almacenamiento en la calidad y vida útil del arándano. El método consiste en comparar una muestra a distintas temperaturas (1 ºC, 13,1 ºC y ambiental) y envases (polietileno, polipropileno y sin empaque), además de un experimento adicional para comparar el efecto del corte ½ en la fruta. Los resultados muestran que las mejores condiciones de almacenamiento para mantener la calidad del arándano según el olor, color, sabor, textura y presencia de moho fueron a 13,1ºC y utilizando polietileno. Las diferencias fueron significativas (p<0,05) frente a otros tratamientos, logrando prolongar la vida útil de la fruta hasta 21 días. Respecto a la fruta cortada, esta tuvo la menor vida útil (4 días) debido al daño mecánico al que fue expuesto y por su exposición al medio ambiente.
