Fruits of Eugenia jambolana were analysed for total phenolics and antioxidant activity of three successive development stages viz. 1. Mature green 2. Half - ripened and 3. Fully ripened. The total anthocyanin concentrations were higher in fully ripened stage, the total phenolic content was maximum achieved in mature green stage (354 mg L-1). Antioxidant activity also strongly depended on ripening stages, showing completely opposite compared to that of total phenolics. Since total phenolics and antioxidant activity performed nearly “Object and its reflection in the mirror” trend.

Background. Recently, many studies have been oriented towards improving methods and efficiency of antioxidants recovery from different fruit and their wastes. The aim of the study was to evaluate antioxidant potential of apple seeds and peel, which constitute the fruit industry wastes, and compare it to apple flesh. Antioxidant activity of apples at different maturity and storage stage were analysed too. Material and methods. The Idared and the Šampion cultivars of apples were used in the study. Antioxidant activity was estimated using ABTS and DPPH assays, and polyphenols profile was determined by HPLC method. Results. Seeds of analysed apple cultivars were characterised by a significantly higher antioxidant capacity and by higher concentrations of polyphenols analysed when compared to their peel and flesh. There were present two predominant compounds: phloridzin in seeds (84% and 72%) and quercetin glycosides in peels (54% and 38%, Idared and Šampion cultivars, respectively). No quercetin glycosides in seeds were found. The capacity to scavenge an ABTS radical, but not DPPH, decreased during ripening of apples, while cold storage resulted in enhanced antioxidant potential. Conclusion. It can be concluded that unripe apples together with apple seeds and peel (fruit industry wastes) constitute a valuable source of polyphenols.

The aim of this study was to examine of exogenous calcium uptake by 8 cultivars of apples (Malus domestica Borkh.). Fruits at harvest time were dipped in 1% CaCl2 solution and stored at 18-20 C during 14 days. Apples dipped in water served as control. The results showed significant differences between cultivars in apple calcium content. The least fruit calcium content was observed by cv. Jonagold and the highest by cv. Lobo. It was found significant, positive correlation between fruit calcium content and ability of apples to exogenous calcium uptake. The study showed that intensity of apple surface cracking is not a main factor influencing on exogenous calcium uptake. Apple peel surface without the blush was more sensitive to form the microcrackes than surface with the blush.

Due to the unique taste features and pro-health values of fruits, hot pepper is cultivated in Poland on the commercial scale, most frequently with the use of single harvest which results in fruits at various maturity stage: green fruits, fruits turning colour and physiologically mature fruits (red). This paper, based on the results of 3-year experiments, evaluates utility and biological value of fruits of four Polish cvs.: ‘Bronowicka Ostra’, ‘Orkan’, ‘Cyklon’ and ‘Rokita’. Agricultural study was conducted for three years, during the period 2009–2011. Fruits of various maturity stage consisted of the marketable yield of the and hot pepper from a single harvest. The evaluated cultivars differed in utility and biological value of fruits, quantity and fruit yield structure. The greatest yield was obtained from ‘Orkan’ and ‘Rokita’ cvs. (2.17 kg·m-2 ), yet the greatest yield of physiologically mature fruits (1.16 kg·m-2) from ‘Bronowicka Ostra’ cv. whose share in marketable yield was 65.0%. Biological value of fruits depended on maturity stage and cultivar genotype. Physiologically mature fruits contained most dry mass (13.18%), soluble solids (4.4%), L-ascorbic acid (199.9 mg·100 g-1 f.m.), total sugars (2.92%). Yet more capsaicinoids were proved in green fruits and fruits turning colour. Least dry mass (%) and total sugars (%) were noted in ‘Orkan’ cv., whereas least L-ascorbic acid in ‘Bronowicka Ostra’ cv., in which fruits at every stage of maturity accumulated most capsaicinoids.

Studies were carried out on the plum collection maintained at Research Institute of Pomology and Floriculture in Skierniewice, Poland. Observations conducted in the years 2003-2005. Plum cultivars according to ripening time were divided into 5 groups: early ripening (15.07. to 31.07.), mid-early (1.08. to 10.08.), middle (11.08. to 31.08.), mid-late (1.09. to 25.09.) and late (26.08. to 20.10.). With regard to fruit weight the evaluated plum cultivars were classified as follows: very small (up to 20 g), small (21-30 g), medium (31-40 g), medium large (41-50), large (51-60), and very large (over 61 g). In the case of early ripening plum cultivars with small and middle fruits dominated. In the group of mid-late ripening time cultivars with quite big fruits pay big role. However, in the group of late ripening cultivars with small fruits (represented mostly by ‘German Prune’ types) as well as with very large fruits (e.g. cvs Empress, Oneida, President and others) were present.
