In this study, cornelian cherry (Cornus mas L.) peel (CCP) was incorporated into a probiotic ice cream formulation containing Bifidobacterium lactis to investigate the potential effect of CCP on the viability of B. lactis in the ice cream after simulated gastrointestinal stress and during 120 days of storage. Furthermore, the effect of the addition of CCP (3, 6, and 9%) on bioactive compounds, antioxidant activity, and physicochemical and sensory attributes of the ice cream was evaluated. The results showed that the addition of CCP significantly enhanced vitamin C, total polyphenols, total anthocyanin content, and antioxidant activity of the ice cream. During frozen storage of the ice cream, phenolic compounds and anthocyanins were quite stable, but vitamin C significantly decreased. The addition of CCP had no significant effect on the viability of B. lactis throughout the freezing process, but increments of 6% and 9% CCP increased the viability of B. lactis in the ice cream and after simulated gastrointestinal processes in all storage periods. These findings imply that CCP is a promising candidate to be used for producing functional ice cream.

The study on the effect of pretreatment (blanch and steam) and ripening stage (ripe and unripe) on nutrient content and antioxidant potential of Lepisanthes fruticosa whole fruit powder was carried out with the purpose to develop a potential functional ingredient. The results showed that blanching and steaming have significantly affected (p<0.05) the fat content, vitamin C, total anthocyanins content and antioxidant activity of L. fruticosa whole fruit powder regardless ripening stage. Both pretreatments could increase the vitamin C content, but blanching treatment alone was observed has lowered the fat content and enhanced the antioxidant activity (EC50). Moreover, the ripe L. fruticosa whole fruit powder that has undergone blanching treatment showed higher retention of total anthocyanins content. However, higher retention of total anthocyanin content was observed in the steamed sample of the unripe stage. Upon ripening, protein and ash content were decreased, contrarily with carbohydrate and vitamin C content. Vitamin C content in the ripe sample showed an increment of more than 80% than that of the unripe sample. Meanwhile, antioxidant activity in the unripe sample showed higher activity than that of the ripe sample, although both stages showed EC50 values ≤ 1 mg/mL. These results might be important for establishing a functional ingredient made with L. fruticosa whole fruit.

The article gives a comparative analysis of the data obtained by Russian and foreign scientists considering the content of vitamins and other valuable substances in raspberry fruit. That determines high antioxidant properties of raspberry. The goal of the study was to generalize information which shows specific nature of that plant in relation to the complex of vitamins and polyphenol compounds which it contains. The author shows that fruit of raspberry R. idaeus L. consists of 5–40 mg/100 g of vitamin C, folic acid - 26-44 mg/100 g. Consumption of only 100 g of raspberries satisfies daily requirement of vitamin C (60 mg) by 8.3 - 66.7%, in folates (200 mg) by 13–22%. Total anthocyanin content in red raspberry varies within wide range (20–100 mg/100 g), in black raspberry – form 200 to 600 mg/100 g. Raspberry accumulates from 38 to 270 mg/100 g of ellagic acid. In small amounts the cultivated red raspberry consists of the following substances: carotenoids (β-carotene – 9.3 mg/100 g, zeaxanthin – 11 mg/100 g, lutein – 320 mg /100 g), vitamin E – 0.15–0.44 mg/100 g tocopherol equivalents, thiamine – 0,020 mg/100 g, riboflavin – 0.034 mg/100 g, niacin – 0.036 mg/100 g, pyridoxin – 0.05 mg/100 g, biotin – 5.7 mg/100 g. Total content of antioxidants in the cultivated raspberry fruit is 1.71 mg/g (standard quercetin). As a result of the analysis of different literary sources the author determined that raspberry antioxidant properties are mainly connected with high polyphenol content. Contribution of vitamin C into total antioxidant activity is relatively low. Though raspberry fruit chemical composition has already been studied quite well it is necessary to perform further more detailed research of different raspberry cultivars considering their total antioxidant activity as well as certain biochemical components which comprise antioxidant complex of raspberry fruit. The obtained results will form the base for further research aimed at investigating phytochemical compounds of fruit crops which have become an essential part of healthy human diet and developing nutraceutical products.

Pomegranate juice is popular due to its unique health benefits, sensory characteristics and also a good source of bioactive compounds. Comparative study on processing effect of Not from Concentrate (NFC) and Reconstituted from concentrate (RFC) pomegranate juice on the nutritional and sensory characteristics of ‘Ganesh’ variant was conducted. Results showed that not much differences observed in parameters like pH, acidity, essential elements, protein, total sugars and polyphenol content between NFC and RFC. As per the study NFC had a better antioxidant activity with intracellular ROS inhibition of 11% higher with significant ( p < 0.05) than RFC in HepG2 cell lines. Total anthocyanin content was significantly different ( p < 0.05) in NFC (428.05 mg/l) compared to 326.74 mg/l in RFC expressed as cyanidin-3-glucoside. Iron uptake was 40 units (µg/mg protein) higher in NFC than RFC ( p < 0.05) in HepG2 cells. Sensory flavor profile showed NFC having significant differences with respect to characteristic pomegranate freshness, fruitiness, sweetness and astringency mouthfeel. RFC had higher sweetish and cooked flavor with additional vegetable like notes of beet and carrot. Based on the data better antioxidant activity, iron bioavailability, anthocyanin content and sensory attributes were captured in pomegranate NFC juices over RFC juices.

In present study, fruit weight, fruit firmness, external fruit color, soluble solid content, pH, titratable acidity, vitamin C, total phenolics, total anthocyanins, and antioxidant capacity of eight wild bilberry grown in Coruh valley in northeastern Turkey were determined. The blueberry cv. ‘Bluecrop’ is also included study to make comparison with bilberry genotypes. Antioxidant activity of bilberry and blueberry fruits were comparatively assessed by FRAP (Ferric reducing antioxidant power) assay. Significantly higher content of phenolics and anthocyanins was found in bilberry fruits than in blueberry fruits. However blueberry cv. ‘Bluecrop’ exhibited higher fruit weight and vitamin C content than bilberry fruits. Total phenolic and total anthocyanin content was 327 mg gallic acid equivalent and 142 mg of cyanidin-3-glucoside equivalent in 100 g fresh fruit in cv. ‘Bluecrop’ while it was between 492-563 mg gallic acid equaivalent and 307-342 mg of cyanidin-3-glucoside equivalent in 100 g fresh fruits of  bilberry accessions. Moreover, wild accessions approximately had 2-3 folds higher antioxidant capacity than cv. ‘Bluecrop’. Results suggest the possibility of improving the bioactive and antioxidant properties of bilberry cultivars based food products by using wild ones in cross breeding. It was also concluded that genotypes significantly affect their bioactive content and consequently the possibility of using wild bilberry fruits as a potential source of natural antioxidants in food industry.

The main objective of this research was to compare the retention of antioxidant activity and total anthocyanin content of Saskatoon berries dried by freeze drying, microwave-vacuum drying, thin layer hot air drying and vacuum drying. Antioxidant activity of berry samples was determined by DPPH radical scavenging and ABTS radical scavenging, and the pH differential method was used to determine total anthocyanin content of the berry samples. The results showed that the freeze dried Saskatoon berries exhibited the highest retention of anthocyanin and antioxidant activity among the dried samples, followed by microwave-vacuum dried berries, thin layer hot air dried berries and vacuum dried berries. There were significant differences between the berry samples at P<0.05.  DPPH radical scavenging and ABTS radical scavenging were correlated linearly with an R2 value of 0.99 at P<0.05 showing their effectiveness for the determination of the antioxidant activity of the Saskatoon berries. However, the DPPH radical scavenging assay was more effective than the ABTS radical scavenging assay. The results also showed that antioxidant activity of the berries was highly correlated with the total anthocyanin content of the fruit. The reduction of anthocyanin in dried berry samples was linearly correlated with the reduction of DPPH radical scavenging with an R2 value of 0.97 at P<0.05 and, also, linearly correlated with the reduction of ABTS radical scavenging with an R2 value of 0.88 at P<0.05.

Comprehensive Comparison

Commercial blueberry production has been a viable industry throughout the world for 95 years; because of blueberry is a good source of antioxidant. Blueberries are especially rich in anthocyanin, a flavonoid with potent antioxidant capacity. The aim of this study was to compare the phenolic quantities, antioxidant activities, anthocyanin, sugar and phenolic compounds of blueberries produced in Turkey with those of similar blueberry varieties produced around the world. As a result of the conducted analysis, the total phenolic content (TPC) amount found in the berries was 77.26-215.12 mg GAE/100 g, the total flavonoid content (TFC) was 30.44-91.69 mg QE/100 g and the total anthocyanin content (TAC) was 43.03-295.06 mg c3-GE/100 g. Examining the antioxidant activities of the berries, DPPH between 1.10-5.65 mg/ml, FRAP between 454.93-36832.96 µmol troloks/100 g, β-Carotene between 40.66-86.48%. It was determined that the natural berries contained much more phenolic compounds and higher antioxidant activity than that of the cultivars The result of HPLC analysis, chlorogenic acid is determined to be the dominant compound in all berries. Furthermore, fructose and glucose are found in all fruits in different quantities while sucrose is found in certain varieties of berries as well. At the end of the performed study the data indicate that wild and cultivars of blueberries are rich sources of antioxidants for local as well international industries importing this fruit for food processing and enormous products.
