This study aimed to evaluate the impact of widely grown fruits (wild roses, elderberries, sea buckthorns, rowans, chokeberries, and hawthorns) as a functional ingredient in wheat-flour cookie formulation on antioxidative properties with a simultaneous reduction of the carcinogen-like compound acrylamide. The organoleptic features of the cookies were assessed by a panel of consumers. The following parameters were measured: chemical composition, total polyphenols, polyphenolic profile, antioxidant activity, and acrylamide content. The overall ratings of the tested cookies with the addition of chokeberries, hawthorns, sea buckthorns, and elderberries were more than satisfactory, while wild rose and rowan cookies were the most widely accepted and best rated by the panelists. The antioxidant activity of the tested cookies was 1.1-15.22 μmol trolox·g-1 dm and 2.46-26.12 μmol Fe (II)·g-1 dm as measured by the ABTS and FRAP methods, respectively. All the fruit-enriched cookies had significantly higher antioxidative properties (p < 0.05) in comparison to the control cookies, but among the fruit-enriched cookies, there were differences in the quality and quantity of particular polyphenols. The acrylamide content was significantly decreased by 59% (hawthorn), 71% (rowan), 87% (wild rose), 89% (sea buckthorn), 91% (elderberry), and 94% (chokeberry) compared with the control cookies (p < 0.05). Cookies enriched with wild-grown fruits could constitute a promising novel snack food.
V extraktu kůry Sorbus aucuparia byl stanoven metodou GC-MS kvantitativní obsah 40 karboxylových kyselin s prevalencí hexadekandiové, lignocerové, behenové, azelaové, palmitové a benzoové kyseliny, a 39 složek silice. V etanolickém extraktu kůry Sorbus aucuparia byl metodou HPLC kvantitativně stanoven obsah šesti fenolických sloučenin, tj. kyseliny chlorogenové, kávové a galové, katechinu, kvercetinu a apigenin-7-glukosidu.
The quantitative contents of 40 carboxylic acids, with the prevalence of hexadecanedioic, lignocerinic, behenic, azelaic, palmitic and benzoic acids, and 39 components of essential oil were determined in the extracts of the bark of Sorbus aucuparia by the GC-MS method. The quantitative contents of 6 phenolic compounds, i.e., chlorogenic, caffeic, and gallic acids, catechin, quercetin, and apigenin-7-glucoside were determined by the HPLC method in the ethanolic extract of the bark of Sorbus aucuparia.
In this study, biochemical profile of fruits of 9 Sorbus genotypes was analyzed. The content of total sugars ranged from 69.7 g/kg ('Titan') to 217.5 g/kg (Sorbus torminalis) and total organic acids from 17.7 g/kg ('Businka') to 40.2 g/kg (S. torminalis). The highest content of total anthocyanins had 'Burka' (871 mg/kg FW) and 'Businka' (856 mg/kg FW). Quercetin derivatives represented more than 95% of total flavonols. 'Alaja krupnaja' had 3.5- to 29-fold higher rutin content than other analyzed genotypes. S. torminalis fruits had the greatest diversity of isorhamnetin and kaempferol derivatives. Chlorogenic acid was the major hydroxycinnamic acid and its share was 33% to 73% of total analyzed hydoxycinnamic acid derivatives. The richest in chlorogenic acid were 'Krasavica' and 'Alaja krupnaja' fruits. Cultivar 'Businka' had the highest content of epicatechin (40.7 mg/kg) and neochlorogenic acid (1061 mg/kg). Different procyanidin oligomers were detected among flavanols in Sorbus fruits. The highest content of total flavanols was measured in 'Alaja Krupnaja' fruits. Cultivars 'Krasavica' (84.5 mg/kg) and 'Burka' (85.1 mg/kg) had 1.2- to 6.9-fold higher amount of total carotenoids. 'Businka' was highlighted as the richest in total tannin and phenolic contents (3768 mg GAE/kg) and consequently, it had the highest antioxidant activity (57.6 mM TE/kg FW). Being abundant in polyphenolics, some extracts of Sorbus genotypes, for example, 'Businka,' 'Burka,' and 'Alaja krupnaja' could serve as valuable resource of bioactive compounds to food and pharmaceutical industries.
