Abstract: BACKGROUND: Berries are important sources of crucial dietary components (such as vitamins and minerals), as well as various phytonutrients that may be potentially beneficial to human health and could be used against chronic diseases including cancer and cardiovascular disorders. OBJECTIVE: The current study aimed to identify and analyze the 100 most cited papers related to berry research. METHODS: The Scopus database was searched to extract data. Two of the authors independently evaluated the manuscripts for relevance. Bibliometric data, including citation count, were analyzed together with the words in the titles and abstracts of the 100 most…cited berry-related papers. RESULTS: Seventy-two of the 100 most cited papers were research articles. Most of them were published during the 2000 s, and related to subject areas of agricultural and biological sciences (n = 64), biochemistry, genetics and molecular biology (n = 35), chemistry (n = 29), medicine (n = 24), and nursing (n = 10). Journal of Agricultural and Food Chemistry was the dominating choice of publication outlet (n = 26). CONCLUSIONS: Antioxidant and anticancer benefits appeared to be the major subject terms. Berries that were mentioned in at least 10% of the 100 papers were strawberry, blueberry, cranberry, raspberry, blackberry, bilberry, and grape berry. The review could provide a valuable guide for designing future studies based on berries, berry extracts, and bioactive compounds.
Abstract: BACKGROUND: Yerba-mate (YM) and blackcurrant (BC) are rich in polyphenols and anthocyanins with proven health benefits therefore they could be used in functional beverage preparation. OBJECTIVE: To (a) develop a palatable powdered beverage with high physicochemical and nutritional quality using YM/BC, (b) determine the effect of in-vitro gastrointestinal digestion on antioxidant content and activity and (c) evaluate beverage’s acceptance temporal changes and dynamic profile during multiple intakes. METHODS: We determined powder’s water-activity (aw), moisture content, flowability, micro-morphology, color, cold water solubility, glass-transition temperature (Tg), total polyphenols (TP)/anthocyanins (MAC) and ascorbic-acid contents, antiradical activity (DPPH).…RESULTS: Powder’s aw (0.089) ensured biochemical/microbiological stability. Tg(55.64°C) indicated that YM/BC’s vacuum- storage at 20–25 °C was possible without losing glassy state. Powder’s cold water’s solubility was 90%. 1 L (60 g/L) provided 556.8 mg TP/198.11 mg monomeric-anthocyanins. Ascorbic- acid dose was half the recommended daily intake. in-vitro gastrointestinal digestion reduced total polyphenols/monomeric-anthocyanins 59–70 %, but antiradical activity losses were 9%. Overall-acceptance and Time-Intensity curves results were in the Hedonic scale’s “Like moderately to like very much” zone. Berries/Sweet were the only dominant attributes Astringency accumulative effects not detected. CONCLUSIONS: The YM/BC powder had good physical/biochemical/microbiological stability under industrial storage conditions and high antiradical activity after simulated gastrointestinal digestion. Sensory scores suggested that consumer’s acceptance could be high.
Abstract: Fruit berries are one of the most effective source of bioactive food ingredients with multiple health benefits when consumed regularly. Phalsa fruit (Grewia asiatica L.) a native to the Himalayan region grows equally well in tropical areas of the world yet unexplored with regards to its immense nutritional benefits. The phalsa seed, fruit, and pulp contain numerous functional phytochemicals that can be used to treat various diseases, and have be found to be highly effective in improving respiratory and cardiac functioning. Its cultivation has been limited to subsistence cultivation and it is sold in the form of raw fruit…mostly. There are certain challenges as regards to its perishable nature of the berry fruit, and the optimization of the crop yield. Therefore, this comprehensive review is designed to highlight its economic and nutritional potential for the food and beverage industry as an effective source of bioactive functional food/beverage ingredients. Further potential area of research and developments have been identified for the subsequent authentication of health effects of phalsa berry fruit. Moreover, issues related to value addition in food product development have been explained along with proposed solutions.

Abstract: BACKGROUND: Pomegranate (Punica granatum L.) juice is a highly-valued beverage that has been demonstrated to have large quantities of polyphenolic compounds with powerful antioxidant properties. Currently there is limited information related to other components of the juices of USDA germplasm. OBJECTIVE: Preselected pomegranate germplasm was evaluated to identify unique cultivars with consumer-friendly traits and to select candidates that meet or exceed juice quality parameters of ‘Wonderful’ juice. METHODS Juices from 14 cultivars and commercial pomegranate juice were analyzed using a variety of methods. Juice quality was determined by measuring pH, titratable acidity, citrate, malate, total…soluble solids, maturity index, glucose, fructose, γ -Aminobutyric acid (GABA), antioxidant activity, total phenolics, potassium, glutamate, glutamine, and ethanol. RESULTS Candidate cultivars meeting ‘Wonderful’ juice quality specifications and nutritional profile were identified as were candidates with desirable traits not seen in ‘Wonderful’. There were significant differences among cultivars in pH, titratable acidity, citrate, malate, total soluble solids, maturity index, glucose, fructose, GABA, potassium, glutamate, glutamine, and ethanol. There was no evidence for differences in antioxidant activity and total phenolics of juices among cultivars. CONCLUSIONS: Pomegranate cultivars other than ‘Wonderful’ could provide a broader palette of flavors for the consumer, but more research is needed to determine commercial potential of USDA germplasm.
Abstract: BACKGROUND: Charcoal rot of strawberry (Macrophomina phaseolina ) is an emerging disease difficult to manage, a desirable alternative is the use of resistant cultivars. However, little is known regarding the reaction of cultivars to the pathogen under water stress conditions. OBJECTIVE: The aims of this work were to study the effect of water stress on the physiology of four strawberry cultivars during the infection, and to determine the relationship between water stress and cultivar susceptibility. METHODS: Healthy and inoculated plants of ‘Monterey’, ‘Albion’, ‘Camarosa’ and ‘Sabrina’ were maintained under no irrigation and full…irrigation regimes, in greenhouse conditions. Stem water potential (SWP) and stomatal conductance (gs) were evaluated. The disease severity was recorded weekly for seven weeks. RESULTS: The disease detrimentally affected the water relations in ‘Sabrina’, ‘Albion’ and ‘Monterey’. A significant correlation was detected between the evaluated parameters and the disease severity. The disease severity increases in plants with no irrigation, regardless of cultivar. CONCLUSIONS: Our results show that the infection caused by M. phaseolina increases the negative effects of water stress, depending on the genotype, and that the cultivars that were able to maintain more stable water relations respond better to the disease.

Abstract: BACKGROUND: Oxidation is a deteriorating process in foods that affects sensorial quality and nutritional value. As a result, there has been a tendency to develop and consume functional antioxidant foods which delay oxidative processes. Anthocyanins are polyphenols which have been associated with high antioxidant activity. OBJECTIVE: To study the protection effect of corozo and grape extract with high anthocyanin content, on the oxidation time of yogurt. METHODS: Colorimetric and fluorimetric assays were used to determine anthocyanin content and antioxidant capacity in the extracts over time. For the yogurt, total phenol content was evaluated and antioxidant capacity…by ABTS and ORAC. Also, the pH and color parameters (CIELAB - L*a*b*) were determined for the extracts and the yogurt. Finally, the oxidation of lipids and proteins in the yogurt were determined. RESULTS: A mixture of extracts from corozo and grape had good oxidative stability during the first month of study. There was also protection from oxidation in proteins and lipids during the 21 days of study in a yogurt prepared with the mixture of extracts. CONCLUSIONS: The extracts prepared from corozo and grape are adequate to be used as protectors of oxidation of macromolecules in yogurt.
Abstract: BACKGROUND: The worldwide tendency for growing raspberries in different climatic environments demands the need of development new cultivars with good adaptability. OBJECTIVE: The aim of the present study was to study the adaptability of red raspberry selections for tropical conditions. RESULTS: Days to flowering, days from flowering to first pick, days to first pick, and days from transplanting to last pick were from 135 to 183 days, 22 to 49 days, 163 to 222.3 days, 250.0 to 299.5 days, respectively. Harvest period varied among genotypes, and the genotypes S.39 and S.27 had the…longest harvest period and the highest marketable yields, evidencing their good adaptability to tropical conditions. Berry weight varied from 2.74 to 5.37 g, suggesting that the studied selections produced fruits with small and intermedium size. In addition, these results indicated that such genotypes might be suitable for fruit exportation to different international markets. CONCLUSION: The present study demonstrated the adaptability of certain genotypes such as S.39 and S.27 at a tropical environment, which might be a good option for raspberry growers producing for fresh consumption.
Abstract: Anthocyanins are plant pigments widely present in fruits and vegetables that exert health benefits as part of human diet. They exist in not glycosylated forms (anthocyanidins) and glycosylated forms . Anthocyanins have been studied for their ability to inhibit polysaccharide metabolism enzymes (such as α -glucosidase) and, therefore, attenuate hyperglycemia and modulate type II diabetes. The aim of the present work was to compare the inhibitory activity of anthocyanins with that of acarbose, a common α -glucosidase inhibitor, by evaluating IC50 and Km , to compare the inhibitory capabilities among different compounds in an in vitro study.…Our results showed that most of the anthocyanins studied presented lower IC50 values than acarbose; only Pn-3-glc presented IC50 value close to acarbose. Moreover, there was no difference in Km between complete competitive and complete non-competitive types of inhibition (T -test, p > 0.05). In conclusion, the anthocyanins and their degradation products work together on attenuating abilities of this sugar metabolism key enzyme, throughout competitive and non-competitive modes.
Abstract: BACKGROUND: Aerobic organisms are equipped with enzymatic defence against oxidative stress. However, protection might be also provided by nonenzymatic antioxidant compounds. Ruminants can make polyphenols bioavailable because of the unique properties of their digestive system. OBJECTIVE: It was assumed that chokeberry pomace may be considered as additive rich in plant antioxidants, able to be deposited in small ruminants muscle tissue. METHODS: The study was conducted, using native breeds of lamb - Polish Merino and Wrzosówka. The experimental animals received chokeberry pomace as an addition in amount 150 or 300 grams per each kg of basic feed.…Muscles obtained from lambs were assayed for antioxidative properties of enzymatic systems (superoxide dismutase, glutathione peroxidase) and nonenzymatic compounds or their equivalents (total nonenzymatic antioxidant capacity, potential to scavenge the free DPPH radical, total polyphenols content) contained in tissues. RESULTS: Obtained results provide novel information about bioactivity, bioretention and potential applications of dietary polyphenols in livestock feeding. One of the important findings concerns activity of glutathione peroxidase in the saddle of Polish Merino’s animals (control group had activity of 376 nmol/min/mL, the group which received 150 g of chokeberry pomace had 468 nmol/min/mL, and 300 g of supplementation resulted in activity of 738 nmol/min/mL). The decreased peroxidation process related with malondialdehyde levels in saddle and leg (respectively) of the Polish Merino (control group - 7.50μ M, 7.75μ M, group with 150 g of chokeberry pomace 5.25μ M, 6.70μ M, and with 300 g of pomace- 3.63μ M, 3.83μ M) and Wrzosówka animals (control group - 5.5μ M, 11.5μ M, group with 150 g of chokeberry pomace addition - 4.25μ M, 10.4μ M, and with 300 g of pomace - 3.48μ M, 5.80μ M) is crucial in the context of animal health and meat quality. CONCLUSION: Since examined parameters related to oxidative status (malondialdehyde level, chemicals and physicochemical parameters) respond to chokeberry pomace addition, the later may bring many benefits connected with antioxidative cellular protection.
Abstract: BACKGROUND: The strawberry is one of the most important small fruits; it is widely cultivated in the world and is sometimes subjected to drought stress. Investigating the effects of drought stress on cultivar related plant physiology is necessary to broaden the knowledge of resistance mechanisms to drought. OBJECTIVE: The present study was conducted to investigate the morpho-physiological characteristics of drought tolerance and the relationships between these and strawberry fruit yield under short- and long-term drought stress conditions. METHODS: The effect of two strawberry cultivars, Queen Eliza and Parus, was examined under four moisture regimes. A short-term…stress for one month and a long-term stress for four months were undertaken in greenhouse condition. RESULTS: The analysis of variance indicated significant differences between the cultivars for carotenoid content, relative water content, relative water loss, stomatal conductance and quantum yield of photosystem II under short-term stress and stomatal conductance, and carotenoid content and membrane stability under long-term stress. Correlation analysis revealed that yield correlated positively with relative water content and quantum yield of photosystem II (Fv/Fm), under short- term and long- term stress. Using factor analysis, totally four factors were identified that accounted for 82.14% of the total variance. The factors were in decreasing order of influence yield components, photosynthesis, physiological characteristics and chlorophyll. CONCLUSIONS: Generally, ‘Parus’ was superior to ‘Queen Eliza’ in terms of measured traits under short and long-term stress conditions. It seems that measuring physiological traits is a convenient, simple and fast tool for screening genotypes for their drought tolerance.
