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.

Information on antioxidant properties at different ontological stages may help producers and food technologists to identify which cultivar and/or maturity stage are most adequate for their need, therefore this work aimed to study the changes in the antioxidant metabolism during acerola development. Fruit from cv. Flor Branca, BRS366 and Florida Sweet were harvested at different stages: immature green colored (I), physiologically mature with green color and maximum size (II), breaker (III) and full red ripe (IV). After harvest, fruits were selected, divided into four replications with 500 g each and evaluated regarding their titratable acidity, pH, soluble solids, total soluble sugar, vitamin C, polyphenol, anthocyanin, yellow flavonoid, total antioxidant activity and antioxidant enzyme activity. Anthocyanin and flavonoid were determined through LC-DAD-ESI/MS and all analysis followed a completely randomized factorial 3 x 4 design. Fruits of 'Florida Sweet' presented significantly higher soluble solids (9.46ºBrix). Vitamin C content decreased during ripening, but ripe 'BRS 366' fruits showed the greatest values (1363 mg.100 g-1) and highest TAA with 42.36 µM TEAC.g-1FW. Cyanidin 3-rhamnoside (520.76 mg.100 g-1 DM) and quercetin 3-rhamnoside (33.72 mg.100 g-1 DM) were the most abundant anthocyanin and yellow flavonoids found mainly in 'Flor Branca' fruit of acerola, whose antioxidant enzymes activities were also higher. Ripe 'Florida Sweet' fruit presents a great potential for fresh consumption, meanwhile physiologically mature 'BRS 366' fruit seems the best option for the bioactive compounds processing industry. As 'Flor Branca' fruit of acerola kept the highest activity levels, it could be an indicative of greater potential for postharvest conservation.

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.

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.

Unripe Fruits

Five Korean blueberries (’’Nelson’’, ’’Duke ’’, ’’Bluejay ’’, ’’Toro’’, and ’’Elliot ’’) were harvested at two maturity stages (unripe and ripe) to evaluate fruit quality and antioxidant activities. The Hunter L, a, and b color of ripe blueberries was lower than that of unripe fruit. Soluble solid concentration (SSC) and pH increased, and titratable acidity (TA) and firmness decreased as the blueberries matured. The ripe blueberry fruits showed a higher SSC/TA ratio than the unripe fruits. Although total anthocyanin, flavonoids, phenolics content, and antioxidant activity were higher in ripe blueberries than in unripe fruit, the unripe fruit had higher acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibition activities than ripe fruit in all cultivars. Total antioxidant activity was highly correlated with total flavonoids and phenolics. The relationships between the total antioxidant activity and the AChE or BChE inhibitory activity are negative. There were several physicochemical quality and antioxidant activity differences in blueberries, depending on the cultivar and the maturity at harvest. Unripe fruits also contain potential health-promoting bioactive compounds as functional food ingredients.

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 presents the results of a biochemical study of the total antioxidant activity of water during the Clarias gariepinus farming in closed containment aquaculture system, including the dynamics without replacement. For the first time is shown an increasing the total antioxidant activity with the highest values in the lower part of the biological filter. According to the results of daily observation, the fish behavior was adequate until the end of the experiment, which was stopped with the beginning of their mass death (more than 20%). Researches have shown the promise of using the indicator of total antioxidant activity to assess the work of the closed containment aquaculture system for hydrobionts farming. The issues of reducing the cost of farmed fish by the closed containment aquaculture system using aquaponics, which distinguished among other technologies by the high quality of environmentally friendly food products while significantly saving water resources which is an important problem for closed containment aquaculture system are considered. Food plants feed on bacteria from the waste products of fish while they consume the necessary secretion products from water – chemicals (nitrogenous, potassium, phosphorus compounds), naturally purifying the water. Aquaponics simulates the natural whirlpool, using the natural processes of fish vital functions for plants nutrient medium. As food plants can be used Salicornia europaea and glycophyte Nasturtium officinale, which has a high productivity and high content of vitamins, iron and glycosides. Both plants are tested in the closed containment aquaculture system including human, increased degree of isolation.

Tomato lines carrying the genes Aft, atv, Abg, hp-1, and an as yet undetermined gene from the introgression line LA2099 have been combined to produce fruit with elevated anthocyanin content. The antioxidant activity of juice made from anthocyanin-expressing tomatoes was compared to juices made from tomatoes with varied carotenoid content. The contribution of anthocyanin to the total antioxidant activity of the whole fruit in current material is small, but with potential for significant improvement. The increase in flavonoids in the elevated anthocyanin lines has increased water-soluble antioxidant activity of the fruit in vitro.

The paper presents new data on chemical composition and antioxidant properties in extracts of the aerial organs of Saponaria officinalis growing on the territory of the Republic of Buryatia. It was revealed that soapberry leaves extracts contain a number of organic acids such as oxalic, formic, fumaric, succinic, malic, citric, and benzoic ones, the dominant being formic, malic, acetic and citric acids. Of vitamins B2, B3. BC extracted from the plant the dominant one was riboflavin. The method of and Fthigh-performance liquid chromatography helped to reveal five compounds identified as aglycone and glycosidic in character. They are orientin, isoeryentin, isovitinexin-7-О-glycoside, orientin-7-О-glycoside, of which isovitoxin is dominant. The greatest total antioxidant activity was demonstrated by soapberry leaves and inflorescences picked up on abandoned sites of the village of Selenginsk. Extractions from Saponaria officinalis leaves showed showed antiradical and Fe2+-chelating activity comparable to that of the extractions from plants with pronounced antioxidant activity. Thus, the data obtained indicated the antioxidant activity of S.officinalis aqueous extracts due to the presence of natural flavonoids. This fact shows the plant as a promising new source of antioxidants.
