“…Sugar concentration and pH are important parameters for evaluating blueberry quality. This fruit had low pH (2.6), titratable acidity (TTA) of 1.6%, and high amount of soluble sugars (11.2 °Brix), according to the expected range of pH 2.7–3.8, TTA values between 0.3% and 1.3%, and >11 °Brix reported for other blueberry cultivars, these values also being influenced by environmental and growing conditions [ 26 , 27 , 28 ].…”

The aim of this study was to evaluate Andean blueberries (Vaccinium floribundum Kunth) from Ecuador as a potential functional ingredient for the food and pharmaceutical industries. The analysis of bioactive compounds by HPLC–DAD–MSn determined a high content of (poly)phenols, mainly anthocyanins, and the presence of the carotenoid lutein. Regarding its biological properties, Andean blueberry did not show toxicity by the zebrafish embryogenesis test, showing also a lack of the antinutrients lectins. Moreover, the results of in vitro and in vivo antioxidant capacity evaluation suggested its possibility to be used as natural antioxidant. This fruit also exhibited antimicrobial activity toward Staphylococcus aureus and Escherichia coli in low doses. Finally, in vitro gastrointestinal (GI) digestion showed a partial bioaccessibility of (poly) phenols (~50% at the final step), showing high antioxidant capacity in the different GI phases. These results revealed Andean blueberry as an interesting candidate for being used as a functional ingredient and the development of further in vivo and clinical assays.

“…The value for the fruit (2.92) was intermediate to those of Highbush cultivars (Molina et al, 2008) (2.80 to 3.20) and similar to those of other cultivars in the Rabbiteye group (Saftner et al, 2008) (2.80 and 3.00).…”

“…vázquez-Araújo et al (2010) found values of 10.4, 12.9 and 10.8 °Brix in the juices of blueberry, blackberry and raspberry fruits, respectively. For mature Lowbush blueberries, Kalt & McDonald (1996) found a mean value of 11.15 °Brix, while Molina et al (2008) showed an average of 11.63 °Brix for Highbush blueberries, and Saftner et al (2008) reported an average of 11.75 °Brix for cultivars of the Rabbiteye group.…”

The objectives of this study were to physicochemically characterize and determine the antioxidant activities and anthocyanin contents of organic Rabbiteye blueberries grown in Southern Brazil and its derived products, in order to investigate the utility of food processing wastes as raw materials for developing products with beneficial health properties. The antioxidant capacity of the blueberries was superior to that of other fruits and juices. The pomace exhibited high activity, albeit lower than that of the fruit, while the flour and the dried blueberries lost 66% and 46% of the original antioxidant activity, respectively. The average anthocyanin contents of the fruits were moderate compared to other sources and species of blueberries. The pomace contains a large amount of anthocyanins while the flour and dried blueberries exhibited a 32% and 42% loss in anthocyanin content, respectively. The use of agro-industrial residues, in addition to adding value and minimizing the impact caused by the accumulation in the environment, can be directed toward the development of new products with bioactive properties.Keywords: blueberry; processing; physicochemical characterization; antioxidant capacity; anthocyanins; HPLC.Practical Application: Knowing that the blueberry is a fruit with high antioxidant capacity and great productive potential in southern Brazil, the characterization and determination of bioactive substances of blueberry fruits and its derived products showed that the utilization of agro-industrial wastes as raw materials can be an interesting alternative for developing new products with health promoting properties and technological applications, such as antioxidants and food dyes, besides minimizing the impact caused by their accumulation in the environment.

“…All evaluated cultivars were from the same field conditions (Summer 2009-2010) in order to avoid the influence of growing conditions such as soil, pH, and water that could affect the pH of the fruits [ 17 ]. The pH and °Brix obtained from each fresh cultivar are shown in Table 1 .…”

“…The initial pH (fresh fruits) founded in “Duke” (pH = 3.74 ± 0.11) was higher than other blueberry cultivars, while the lowest value was obtained for “Elliott” (pH = 2.9 ± 0.06). The reason for these differences would be the citric acid concentration present in each cultivar, which also depends on genetic differences [ 17 ]. The pH values obtained for all the cultivars were in the range of 2.75–3.81, in agreement with previous literature reports for other different blueberry cultivars [ 18 ].…”

Background. Blueberries are considered an important source of health benefits. This work studied six blueberry cultivars: “Duke,” “Brigitta”, “Elliott”, “Centurion”, “Star,” and “Jewel”, measuring quality parameters such as °Brix, pH, moisture content using standard techniques and shape, color, and fungal presence obtained by computer vision. The storage conditions were time (0–21 days), temperature (4 and 15°C), and relative humidity (75 and 90%). Results. Significant differences (P < 0.05) were detected between fresh cultivars in pH, °Brix, shape, and color. However, the main parameters which changed depending on storage conditions, increasing at higher temperature, were color (from blue to red) and fungal presence (from 0 to 15%), both detected using computer vision, which is important to determine a shelf life of 14 days for all cultivars. Similar behavior during storage was obtained for all cultivars. Conclusion. Computer vision proved to be a reliable and simple method to objectively determine blueberry decay during storage that can be used as an alternative approach to currently used subjective measurements.
