Sweet Cherry Cultivars

Transportation of sweet cherry fruits to distant markets and further marketing processes often takes approximately 2-3 weeks. The present study investigates the quality changes during this time period at three stages for three sweet cherry cultivars: ‘Early Burlat’, ‘Napoleon’, and ‘0900 Ziraat’. Following pre-cooling, the sweet cherries were placed in modified atmosphere packages and exposed to the following stages for the indicated durations: transportation (T) [8 days at 2 °C and 85% relative humidity (RH)]; distribution center (DC) (4 days at 6.5 °C and 80% RH), and shelf-life (SL) (2 days at 19 °C and 70% RH). Weight losses at the end of the SL stage were 3.11, 3.18, and 2.74%, respectively in ‘Early Burlat’, ‘Napoleon’ and ‘0900 Ziraat’.Fruit firmness decreased after SL as compared to that at other stages and was more remarkable in ‘0900 Ziraat’. Decreased Chroma values which indicates, the intensity or color saturation were observed in all cultivars, whereas decreased hue angle values colours expressed in degrees were observed in the ‘Early Burlat’ and ‘0900 Ziraat’. In addition, a decrease was noted in the titratable acidity of all cultivars at the end of SL. The total soluble solids, total phenolic content, and antioxidant activities were similar for all cultivars at all stages. The visual appearance scores of ‘Early Burlat’ cherries decreased at the end of SL, because of development of pitting on the fruit surface. The fruit quality changes were limited at T and DC stages; however, these changes became more distinctive during the SL period. It was thus concluded that the SL duration and conditions were of the highest significance with regard to maintenance of the sweet cherry fruit quality.

Abstract This research was carried out to evaluate the phenolic composition, antioxidant capacities, sugars and organic acids content of sweet cherry cultivars (Bianca, Burlat, Johanna 1, Johanna 2, Kordia, Kunzes Kirsche, Merton Premier, Napoleon, Orleans, Regina, Rivan, Schneiders Spate Knorpelkirsche, Summit, Trebnitzer Lotkirsche) grown in Poland. Significant differences were observed between tested cultivars for all studied parameters. The sum of total soluble solids ranged from 14.3 (‘Burlat’) to 20.9 g 100 g−1 FW (‘Bianca’) and that of organic acids from 0.43 (‘Burlat’) to 0.76 g 100 g−1 FW (‘Napoleon’). Fruit of Bianca cultivar showed the highest levels of anthocyanin (108.5 mg 100 g−1 FW) while ‘Napoleon’ and ‘Kunzes Kirsche’ contained the lowest levels (1.5 and 1.8 mg 100 g−1 FW, respectively). Total phenolic contents ranged from 101 (‘Napoleon’) to 558 (‘Bianca’) mg 100 g−1 FW, tartaric esters from 26.2 (‘Summit’) to 66.5 (‘Bianca’) mg 100 g−1 FW and flavonoids from 7.9 (‘Summit’) to 49.1 (‘Bianca’) mg 100 g−1 FW. Bianca cultivar has also the highest free radical scavenging activity assayed by ABTS and DPPH methods 88 and 90% respectively.

Background: The xoconostle (Opuntia joconostle Web.) plant is produced mainly in the Central Highlands region of Mexico. The main aim of this research was to determine the effect of pasteurization on chemical and functional properties of xoconostle juice. Methods: Total Soluble Solids (TSS), pH, Titratable Acidity (TA), total phenolic and flavonoid content, betacyanins, betaxanthins, and reducing and non-reducing sugars contents were determined in both unpasteurized and pasteurized xoconostle juices. In vivo assay using Oral Glucose Tolerance Test (OGTT) was done in male rats to evaluate the anti-hyperglycemic effect of juice. Data were statistically analyzed using SigmaPlot. Results: There was a meaningful increasing (p<0.05) in the pigment contents after the pasteurization process, as betacyanins and betaxanthins contents increased to 0.112 and 0.096 µg/g, respectively. In spite of pasteurized xoconostle, the unpasteurized group showed anti-hyperglycemic effects at 60 min of OGTT. Conclusion: Pasteurization temperature had no adverse effect on the antioxidant activities of xoconostle fruit. Although fresh xoconostle juice revealed considerable anti-hyperglycemic properties in rats, this effect was not found in the pasteurized xoconostle juice.

The Impact

This research investigated the impact of the concentration of pineapple juice on the characteristics of pineapple wine during fermentation with Saccharomyces cerevisiae var. burgundy. Three ratios of fresh pineapple juice to water were mixed to obtain three treatments, which were T1—2:1, T2—1:1, and T3—1:2. The °Brix and pH of all pineapple juice and water ratios were adjusted to 25 and 4, respectively. The results showed that changes in alcohol, pH, Total Soluble Solids (TSS), Total Titratable Acidity (TAA, as citric acid), and Volatile Acidity (VA, as acetic acid) during the 10-day fermentation among three treatments were significantly different. The highest alcohol content was obtained from the 2:1 with values of 10.71% (v/v). The mixed ratio at 1:1 and 1:2 obtained the alcohol value of 9.61 and 8.35% (v/v), respectively. After ten days of fermentation, TSS, pH values, TAA, and VA were in the range of 9.7–13 °Brix, 3.56–3.82, 0.384–0.448, and 0.0013–0.0016, respectively. However, the appearance, aroma, and taste of all ratios were not significantly different. Sweetness and overall liking, wine with pineapple juice/water ratio at 2:1 had the highest score (p ≤ 0.05). The total antioxidant activities determined by DPPH and total phenolic content were 0.91 mmol/L TE and 365.80 mg/L GAE, respectively, as confirmed by FTIR spectral analyses.

Sweet Cherry Cultivars

The research concerning the improvement of the cherry assortment, the cultivars’ quality and the avoiding of market crowding with fresh cherries only on a short term are extremely important objectives for cherries’ breeding. To accomplish some of these objectives, during 1981-2017, hybridization and selection of hybrids were performed at the Research Station for Fruit Growing Iași (RSFG Iași), in the N-E part of Romania, concluding with a series of promising hybrid selections. They have been grafted, planted and studied in trial fields. Therefore, during 1994-2016, RSFG Iași released 28 sweet cherry cultivars with high quality fruits and different maturation stages. In the studies performed during 2014-2017, there were analysed three new sweet cherry cultivars (‘Elaiaşi’, ‘Muşatini’ and ‘Croma’), obtained through controlled hybridization. The comparison of these new cultivars was performed against ‘Van’, used as control, this being a well-known cultivar in the orchards from the study area. Observations and measurements concerning the main phenological stages, natural fertility, physical features, organoleptic, quality and chemical traits of fruit were registered. The cultivars with the biggest dimensions of the fruits were ‘Elaiaşi’ and ‘Croma’ (with a weight between 8.9 and 9.4 g and a fruits’ diameter between 25.2 and 26.6 mm), having significantly larger dimensions in comparison with ‘Van’. In the new investigated cherry cultivars, the values of soluble solids content were comprised between 17.0 and 20.2 °Brix, titratable acidity was between 0.46 - 0.57 mg of malic acid 100 mL-1 juice and the total polyphenols content was recorded between 382.87 - 780.25 mg GAE 100 mL-1 of fresh juice.   ********* In press - Online First.

Varietal Variation

Varietal variation in apricot causes differential changes in fruit quality during ripening. A study was executed to evaluate the effect of apricot varietal variation on fruit physico-chemical and sensory attributes during fruit ripening. Fruits of two apricot cultivars, ‘Old Cap’ and ‘Red Flesh’ obtained from Baluchistan were monitored at ambient conditions (25 ± 2 °C and 60-65% RH) during fruit ripening for physico-chemical and sensory attributes. Irrespective to days at shelf during fruit ripening, fruits of ‘Red Flesh’ apricot exhibited significantly reduced fruit weight loss with greater fruit firmness, total soluble solids (TSS), total phenolic content (TPC), ascorbic acid and antioxidant scavenging activity (ASA) than ‘Old Cap’ apricot fruits. However, titratable acidity (TA) of ‘Old Cap’ apricot fruits remained significantly higher than ‘Red Flesh’ apricot fruits during ripening. At eating soft stage, sensory attributes including fruit pulp colour, taste, flavour and overall acceptability of ‘Red Flesh’ apricot fruits were superior to ‘Old Cap’ apricot fruits. In conclusion, ‘Red Flesh’ apricot showed better fruit physico-chemical attributes during fruit ripening and fruit sensory attributes at eating soft stage than ‘Old Cap’ apricot fruits.

Peach breeders need rapid, non-destructive methods to rate fruit quality changes after picking in order to select genotypes that can be delivered to the consumer with the maximum quality. Changes in ground color and firmness over time can be quantified by use of a bouncemeter (which measures coefficient of restitution) in conjunction with a colormeter. During 1991 and 1992, the ripening patterns of over 100 peach and nectarine varieties and selections were measured, allowing comparisons between different genotypes. Ten fruit, picked when firm ripe, were measured both before and after storage for 5 days at 5°C followed by 2 days at 20°C. Soluble solids (%) for each fruit were then measured with a refractometer, followed by determination of titratable acidity on 2 pooled samples. In general ground color changed from green to yellow and firmness decreased over time, but genotypes varied widely in the relationship of ground color and firmness. There also appeared to be differences in rates of change of these parameters.

Blackberry fruit are considered highly perishable, having an average shelflife of 2 to 3 days. Fruit of erect blackberry cultivars were stored at 2C for 7 days to determine shelflife and quality changes. Weight loss was 1.8 and 3.4% after 3 and 7 days storage, regardless of cultivar or color stage. Soluble solids concentration (SSC), titratable acidity (TA), anthocyanin content, and skin firmness did not change during storage, but differed between ripeness stages and cultivars. Mottled (50% black) fruit were low in SSC and high in TA compared to shiny or dull black fruit. All dull black fruit were rated softer and lower in overall appearance after storage compared to shiny black fruit. `Choctaw' fruit were less firm and rated softer and of marginal appearance after 7 days storage while `Navaho' fruit remained firm and highly acceptable. Ethylene production ranged from 0.4 (`Navaho') to 2.8 nl/g-h (`Choctaw'). Results indicate that erect blackberry fruit harvested at the shiny black stage are of acceptable quality and have excellent shelflife potential.

Crab apple (Malus baccata (L.) Borkh.) was mainly distributed in Europe as an ornamental plant, but the nutritional properties of its edible fruits were not fully revealed. The aim of the current study was to characterize the phytochemical composition of ripen carb apple fruits and to evaluate their nutritional and antioxidant potentials. The fruits were assayed for moisture and ash content, proteins, lipids, carbohydrates, titratable acidity (TA), pH, total phenolic compounds and natural pigments. Among the analyzed carbohydrates cellulose was found in the highest content (6% dw), followed by sugars (sucrose, glucose and fructose) and 1.8 % dw uronic acids. The total chlorophylls and carotenoids contents in their fruits were 6.51 and 4.80 μg/g fw, respectively. Total monomeric anthocyanins were not detected. The highest content of total phenolic compounds (2.67 mg GAE/g fw) was found in 95 % ethanol extract from fruits, while the total flavonoids were relatively low – 0.1 mg QE/g fw. DPPH assay (17.27 mM TE/g fw) and FRAP assay (14.34 mM TE/g fw) demonstrated in vitro antioxidant activities of crabapple. Malus baccata fruits were evaluated as a rich source of dietary fibers and phenolic compounds with significant antioxidant potential that could be used in human nutrition.

Sensory Data

Sweet cherry (Prunus avium L.) is a fruit appreciated by consumers for its well-known physical and sensory characteristics and its health benefits. Being an extremely perishable fruit, it is important to know the unique attributes of the cultivars to develop cultivation or postharvest strategies that can enhance their quality. This study aimed to understand the influence of physicochemical characteristics of two sweet cherry cultivars, Burlat and Van, on the food quality perception. Several parameters (weight, dimensions, soluble solids content (SSC), pH, titratable acidity (TA), colour, and texture) were measured and correlated with sensory data. Results showed that cv. Van presented heavier and firmer fruits with high sugar content. In turn, cv. Burlat showed higher pH, lower TA, and presented redder and brightest fruits. The principal component analysis revealed an evident separation between cultivars. Van cherries stood out for their sensory parameters and were classified as more acidic, bitter, and astringent, and presented a firmer texture. Contrarily, Burlat cherries were distinguished as being more flavourful, succulent, sweeter, and more uniform in terms of visual and colour parameters. The results of the sensory analysis suggested that perceived quality does not always depend on and/or recognize the quality parameters inherent to the physicochemical characteristics of each cultivar.

The green bean is an important crop worldwide, because it is rich in protein, dietary fiber, vitamins, and minerals, as well as bioactive compounds that provide it with important functional properties; however, the composition of many landraces is still unknown. The purpose of this project was to characterize Phaselus vulgaris and coccineus L. landrace green beans on pH, titratable acidity, total soluble solids, total sugars, color parameters, total phenols, monomeric anthocyanins, and in vitro antioxidant activity (DPPH and FRAP). Regarding the content of total sugars, differences were registered between both species, as opposed to results observed in total soluble solids. Color parameters showed higher reddish tones for P. vulgaris landraces, though P. coccineus had a higher total phenolic content, especially the reddish landraces, which correlated directly to a higher antioxidant activity by DPPH and FRAP. In the protein content, the species P. vulgaris registered the highest content. These results could contribute to a greater use and even promote the genetic improvement of the outstanding pods that serve as one of the main food products in rural regions for higher benefits.
