“…The phenolic content found in the extract was 5902.89 ± 7.42 mg GAE/L (the phenolic extract had an equivalent of 3300 g of pulp/L). This amount is equal to 177.26 mg GAE/100 g of pulp which falls within the range found for other fruits from the Rubus generum (Zielinski et al, 2015;Ferreira et al, 2010). Rufino et al (2010) suggested a classification scheme where the phenolic content of fruits could be grouped as low if the concentration was <100 mg GAE/100 g of fruit, medium for the range 100-500 mg GAE/100 g and high for >500 mg GAE/100 g. Based on this classification, R. rosaefolius would be classified as having a medium content of phenolic compounds.…”

The glucose and fructose contents of the wild blackberry accession studied in this research were markedly richer compared to the amounts described by Zielinski et al [19] in Brazos and Tupy blackberries grown in southern Brazil: glucose (3.11 and 3.30 g¢100 g ¡1 ) and fructose (2.86 and 2.49 g¢100 g ¡1 ). Sensoy et al [27] quantified the fructose (8.84À16.31 g kg ¡1 ) and glucose (1.48À3.89 g kg ¡1 ) contents in wild blackberries from Van, Turkey.…”

Sugars (glucose and fructose), organic acids (citric acid, tartaric acid, oxalic acid, malic acid, succinic acid and fumaric acid), vitamin C, phenolic compounds (catechin, rutin, quercetin, chlorogenic acid, ferulic acid, o-coumaric acid, p-coumaric acid, caffeic acid, syringic acid, vanillic acid and gallic acid) and antioxidant capacity (Trolox equivalent antioxidant capacity, TEAC assay) were determined in fruits of wild blackberry, black and white mulberries from southern Bulgaria. Malic acid was the predominant organic acid for the black and white mulberries. Citric and malic acids were represented with the highest content in blackberries. The highest fructose concentration was observed in blackberries (16.187 g¢100 g ¡1). Black mulberries showed the highest antioxidant activity (12.230 mmol TE g ¡1), followed by white mulberries (8.6133 mmol TE g ¡1) and blackberries (4.490 mmol TE g ¡1). Chlorogenic acid and rutin were the main phenolics in the analysed fruits. The results illustrated significant phytochemical profiles of the studied berries, which could contribute to the medicinal industry and provide valuable genetic resources for breeding programmes.

“…Blackberry (Rubus fruticosus) is a perennial shrub that is native to Europe (Radovanovi c, Anđelkovi c, Radovanovi c, & Anđelkovi c, 2013) and is characterized by being labor-intensive and also for providing a high economic return (Zielinski et al, 2015). In Mexico, 152,921.52 tons were harvested in 2014, making it the largest producer in North America (SIAP-SAGARPA, 2016).…”

In this article, the effect of direct solar drying, indirect solar drying, and freeze drying on the phenolic compound contents and antioxidant capacities of blackberry fruits was investigated. The solar drying kinetics were determined and fitted to six thin layer different mathematical models. The total phenolic, anthocyanin, and flavonoid contents as well as the antioxidant capacity based on ABTS, DPPH, and OH• assays were determined for the dried blackberry samples. The results show that the Midilli–Kuçuk model provides the best fit to the experimental data of solar drying in both methods tested. Greater antioxidant capacities were observed in the samples dried by using direct solar drying method in all experiments, that is, the ABTS, DPPH, and OH• activities were 36,757 ± 1.27; 21.120 ± 1.33, and 47 ± 7.31 μmol TEAC/g dm, respectively. The creation of compounds during food dehydration at moderately high temperatures can enhance the antioxidant capacities and phenolic contents. Practical applications Rubus fruticosus is a berry with nutraceutical potential by the presence of bioactive compounds. The removal of water from a fruit extends the conservation time of the product during storage and transportation, facilitating the access to such foods when required. One of the most economical and sustainable ways to do the drying is to use solar dryers. Direct and indirect solar drying are technologies that have effects that must be taken into account according to the food that is to be dried and the final characteristics that are desired to obtain. However, the phenolic compounds present in the fruit are sensitive to the thermal process. Thus, it is important to know its consequences phenolic compounds and antioxidant activity for better use of the fruit.
