The number of consumers seeking safe and health-beneficial foods is systematically increasing. Consumers demand more environmentally friendly and safe food options coming from organic farming. Blackcurrants fruits are a perfect source of biological active compounds, such as vitamin C, polyphenols and flavonoids as well anthocyanins. Organic agricultural practices have modified the level of bioactive compounds in blackcurrant fruits. The novelty and the aim of the presented study was to compare the concentrations of selected health-promoting antioxidants in fruits of three blackcurrants (‘Ben Adler’, ‘Tiben’ and ‘Titania’) grown in organic and conventional orchards in Poland. For bioactive compound determination, the high-performance liquid chromatography (HPLC) method was used. The obtained results showed that organic blackcurrant fruits contained significantly more vitamin C (9.4 mg/100 g f.w.), total polyphenols (189.2 mg/100 g f.w.), total phenolic acids (10.3 mg/100 g f.w.), and total flavonoids (178.8 mg/100 g f.w.), as well anthocyanins (167.9 mg/100 g f.w.), compared to conventional ones. The selected cultivars and the years of cultivation system affect the concentration of the measured polyphenols, with strong interactions between these factors. The experiment confirms the hypothesis that organic blackcurrants should be a very important part of well-balanced, healthy diet.

Paprika powder is a good source of different carotenoids and polyphenols, which play a key role in preventing certain diseases (some kinds of cancer and cardiovascular diseases). They can also be used as natural food colorants. Organic production is characterized by strict rules, but products obtained in this way contain more bioactive compounds, such as carotenoids and polyphenols. The aim of this study was to measure and identify carotenoids and polyphenols in different paprika samples (sweet, hot, smoked, and chili) obtained by organic and conventional production. Quantitative and qualitative carotenoid and polyphenols analysis showed that the experimental samples contained different concentrations of these compounds.

Anthocyanins are widely distributed secondary metabolites that play an essential role in skin pigmentation of many plant organs and microorganisms. Anthocyanins have been associated with a wide range of biological and pharmacological properties. They are also effective agents in the prevention and treatment of many chronic diseases. Berries are particularly abundant in these compounds; therefore, their dietary intake has health-promoting effects. The aim of this study was to identify and determine the anthocyanin content in selected species and cultivars of berry fruits, such as raspberry, blackberry, red currant, blackcurrant, and highbush blueberry, widely consumed by Europeans. The concentrations of anthocyanins were determined by HPLC, identifying individual compounds: cyanidin-3-O-glucoside, pelargonidin-3-O-glucoside, delphinidin-3-O-glucoside, delphinidin-3-O-rutinoside, cyanidin-3-O-rutinoside, delphinidin-3-O-galactoside, cyanidin-3-O-galactoside, and malvidin-3-O-galactoside. The experimental data showed that the selected species and cultivars of berry fruits differ significantly in the contents of anthocyanins. Among all species tested, blackberry and blackcurrant were characterized significantly by the highest content of anthocyanins (sum), while the lowest content was found in red currant fruits. Additionally, the content of individual anthocyanin compounds in particular species and cultivars was also different. Considering the high content of anthocyanins and their potential positive impact on human health and protection against disease, berries should be part of healthy nutrition.

A growing demand for organic foods is driven by consumers′ perception that they are more nutritious. However, while there is a number of scientific studies showing some superior qualities of organically grown fruit and vegetables, including, i.e., higher content of phenolics, some vitamins and antioxidant activity, scientific research looking into the quality of processed organic products is very limited. At the same time the consumption of processed, convenient foods, with a long shelf-life, is rapidly increasing all over the world. Among the processed fruit-based products, dried fruits are recognized by consumers as one of the best snacks, highly nutritious and containing a large amount of fibre. In the presented experiment, four types of organic and conventionally produced dried fruits were examined: Apricots, apple rings, cranberries, and prunes. The concentrations of polyphenols (in all products) and carotenoids (in apricots) were measured using high performance liquid chromatography (HPLC). The study confirms that dry fruits can be undoubtedly considered as a rich source of polyphenols, however, a large variation in the concentrations of these compounds among different brands of products was also pointed: 219.03 ± 3.90–296.96 ± 2.86 mg 100 g−1 in dried apricots, 95.24 ± 15.12–627.71 ± 48.64 mg 100 g−1 in dried apple rings, 14.64 ± 0.43–203.09 ± 7.96 mg 100 g−1 in dried cranberries, and 134.65 ± 12.27–422.44 ± 9.00 mg 100 g−1 in prunes. Carotenoids concentrations in dried apricots ranged from 2.72 ± 0.31 to 17.49 ± 0.17 µg g−1. Among the tested dried fruits, only in the case of apricots organic products were characterized by the higher contents of phenolics and carotenoids compared to the conventional brands. In the case of other products there was either no consistent significant production system effect, or the concentrations of the analyzed phenolic compounds were higher in conventional products.

The apple (Malus domestica Borkh.) is one of the most widely cultivated temperate fruits globally, gaining scientific interest as a rich source of antioxidants with a demonstrated beneficial human health impact. Since a growing number of consumers are increasingly seeking safe and healthy food options, alternative fruit production systems such as organic farming, and their potential to provide safe and nutritious foods, have been gaining increasing attention in the last decades. The aim of the presented study was, therefore, to analyse and to compare the concentrations of selected health-promoting antioxidants, such as phenolic acids, flavonols, and vitamin C, in fruits of three apple cultivars (Champion, Gala, and Idared) grown in conventional and certified organic orchards in Poland. All analyses were performed using the high-performance liquid chromatography (HPLC) method. Organic apples tested within the study, compared to the conventionally grown ones, were characterised by significantly higher concentrations of phenolic acids (av. >31%) and flavonols (av. >66%) with the identified differences being consistent in all three cultivars and two seasons. The greatest production system effect was observed in the case of Idared. Significant cultivar and production season effects on the concentration of the measured fruit phenolics, with strong interactions between the two factors, were also identified. Vitamin C content in the fruits was strongly dependent on the year-to-year differences in the fruit growing conditions. The study suggests that the organic production system has a potential to provide apple fruits rich in selected health-promoting phenolic antioxidants.

Food allergies are a very serious problem among consumers. The most common food allergies involve animal products, but they can also involve fruits such as berries. We aimed to determine whether organic farming is useful for the production of high-quality and safe fruits. Three varieties of raspberries ‘Laszka’, ‘Glen Ample’ and ‘Polka’ from organic and conventional production (neighboring farms) were collected over the two years of the experiment. Quantitative and qualitative analysis of phenolic compounds was carried out, and the content of Bet v1 and profilin was determined. The organic raspberries contained a lower level of phenolic compounds, especially anthocyanins. Conventional fruits were characterized by a higher allergenic potency than organic ones. We found a strong link between their anthocyanin content and the allergy status of conventional raspberry fruits. Therefore, organically produced raspberries are safer for consumers.

Raspberry fruit is a source of vitamin C. Vitamin C has antioxidant properties and can neutralize the negative effects of oxidative stress. The aim of this study was therefore to compare the content of vitamin C, sugars and organic acids in organic vs. conventional raspberries and to determine the effects of harvest time and cultivar on the contents of these compounds. The experiment was carried out in 2013–2014. Fruits from four raspberry cultivars ('Laszka', 'Glen Ample', 'Glen Fine' and 'Tulameen') were collected in the summer, and fruits of the 'Polka' cv. were collected in the autumn. The experiment was carried out on three organic farms and three conventional farms. The vitamin C, sugars and organic acids contents were determined using the HPLC method. The conventional raspberries grown in 2013 contained a significantly greater vitamin C (40.5 mg/100 g FW) and dehydroascorbic acid (35.8 g/100 g FW) content compared to organic raspberries (33.7 mg/100 g FW and 29.2 mg/100 g FW, respectively). We observed an effect of the cultivar on the total organic acids and citric acid content in raspberry fruit in 2013 and 2014. ‘Laszka’ cv. (1720 mg/100 g FW and 1650 mg/100 g FW) and ‘Glen Fine’ cv. (1740 mg/100 g FW and 1710 mg/100 g FW) fruits contained significantly more total organic acids and citric acid (1680 mg/100 g FW and 1610 mg/100 g FW) as well (1680 mg/100 g FW and 1670 mg/100 g FW) compared to the other experimental cultivars. However, the 2014 ‘Tulameen’ cv. was characterized by the highest levels of total sugars (14.9 g/100 g FW) and sucrose (5.0 g/100 g FW) content. The conventional raspberry fruits (55.4 mg/100 g FW) harvested in the autumn of 2014 contained a significantly greater malic acid content compared to organic fruits (46.2 mg/100 g FW).

Raspberry fruits are a perfect source of polyphenols, including flavonols, anthocyanins. Some experiments have indicated that organic fruits contain more bioactive compounds than conventional fruits. The aim of this study was therefore to analyse and compare the concentration of bioactive compounds in organic vs. conventional raspberries and to determine the effects of harvest time and cultivar. Three cultivars of raspberry ('Laszka', 'Glen Ample' and 'Glen Fine') that were harvested in summer and one 'Polka' cv. that was harvested in autumn time from organic and conventional cultivation methods were used in the experiment. The contents of dry matter and polyphenols in the fruits were determined. The organic samples contained significantly more dry matter, phenolic acid and flavonoids, including myrycetin, quercetin, luteolin and quercetin-3-O-rutinoside. Harvest time was an important factor in raspberry fruit quality.

The aim of this study was to evaluate and compare the content of a number of bioactive compounds and antioxidant activity of fruits of selected local and commercial sweet cherry (Prunus avium L.) cultivars. The experiment showed that the selected cultivars of sweet cherries differ significantly in the content of polyphenolic compounds and carotenoids. The fruits of commercial sweet cherry cultivars were, on average, richer in polyphenols (the sum of phenolic compounds determined chromatographically), flavonoids, as well as anthocyanins and were characterized by higher antioxidant activity when compared to the local, traditional cultivars. In the group of the traditional sweet cherry cultivars, particular attention could be paid to Black Late cv., showing the highest antioxidant activity of fruits. In the group of commercial sweet cherry cultivars, Cordia and Sylvia fruits could be recognized as being rich in bioactive compounds with high antioxidant activity. Yellow skin cultivars were characterized by the highest concentrations of carotenoids. Strong positive correlations between the identified bioactive compounds and antioxidant activity of fruits were also found. Although different cultivars of sweet cherries show a high variability in phenolics and carotenoids profiles as well as in the antioxidant activity of fruits, they all should be, similarly to other types of cherries, recognized as a rich source of bioactive compounds with an antioxidant potential.

: Raspberry leaves are a source of carotenoids and polyphenols, including ellagic acid and salicylic acid. The results of scientific research suggest that they have potential pro-health properties that contribute to human health. The aim of this study was to determine the polyphenolic and carotenoid profiles in the leaves of selected raspberry cultivars and their in vitro activity. The second aim was to determine the impact of organic and conventional farm management on the polyphenol, carotenoid, and chlorophyll contents in different raspberry cultivars: ‘Polana’, ‘Polka’, ‘Tulameen’, ‘Laszka’ and ‘Glen Ample’. Compared with conventional raspberry leaves, organic raspberry leaves were characterized by a significantly higher content of dry matter, total polyphenols, total phenolic acids, chlorogenic acid, caffeic acid, salicylic acid and quercetin-3-O-rutinoside; moreover, the organic leaves were characterized by higher antioxidant activity. Among examined cultivars, ‘Polka’ c. was characterized by the highest antioxidant status. However, raspberry leaves from conventional farms contained more total carotenoids, violaxanthin, alpha-carotene, beta-carotene, total chlorophyll and individual forms of chlorophylls: a and b.
