Yellow Passion Fruit

During ripening, many transformations occur in passion fruits. The ripening stage affects fruit quality and post-harvest properties. Fruits with 65% yellow epidermis present chemical characteristics that meet industrial standards, facilitating harvest estimations and loss avoidance. Thus, this study aimed to evaluate the post-harvest properties of passion fruit species (genotypes of the yellow passion fruit and sweet passion fruit, and yellow passion fruit cultivar FB 200) during ripening. The fruits were evaluated by the color of the epidermis and the chemical characteristics of the pulp (titratable acidity, vitamin C, carotenoids, soluble solids content, and ratio). This experiment was conducted with a completely randomized design and a split-plot arrangement, where the plots were the species and the subplots were the evaluation periods (50, 58, 66, 74 and 82 days after anthesis), with four replications and 10 fruits per plot. The yellow passion fruit genotype and cultivar, harvested at 82 days after anthesis, presented desirable characteristics for the juice industry and for fresh consumption. The sweet passion fruit had a higher soluble solids content and titratable acidity ratio because of its high content of soluble solids and low acidity, which translate to a better fruit flavor.

Yellow Passion Fruit

Because it is a species of tropical climate, the passion fruit is distributed widely in South America, mainly in Brazil. Its cultivation represents approximately 95% of the commercial orchards of the country, nevertheless, it presents productivity below its productive potential, being necessary to obtain cultivars adapted to the climate of the regions of culture. The objective of this work was to evaluate the quality of the fruit pulp of yellow passion fruit produced in Jataí-GO as well as the correlations between some physical and chemical characteristics. The fruits were collected in an experimental orchard and sectioned transversely to obtain the pulp. The characteristics of acidity, vitamin C content, soluble solids content, soluble solids/acidity ratio (Ratio), and pulp color parameters were evaluated through the coordinates L*, a*, b*, C* and h* of yellow passion fruit and of the cultivar FB 200. Data were analyzed by means of analysis of variance and Pearson’s correlation at 5% of significance with the aid of the statistical program Rbio. It is concluded that the characteristics of the fruits of the cultivar FB200 differed from the fruits of yellow passion fruit and that these characteristics correlated significantly and positively.

Abstract the aim of this study was to evaluate the chemical characteristics and sensory acceptance of juices and cuts of ‘Bordô’ and ‘Niágara Rosada’ grapes. The experimental design was in a one-factor scheme, with five levels. Treatments were: T1 – ‘Bordô’ (100%); T2 – ‘Bordô’ (70%) + ‘Niágara Rosada’ (30%); T3 – ‘Bordô’ (50%) + ‘Niágara Rosada’ (50%); T4 – ‘Bordô’ (30%) + ‘Niágara Rosada’ (70%); T5 – ‘Niágara Rosada’ (100%). Chemical analyses were: content of soluble solids, pH and titratable acidity, and sensory analyses were: color, aroma, flavor, body and global acceptance. For the soluble solids content, the highest averages were verified in T1, T2 and T3 treatments. As for pH, the highest value was recorded in T3, T4 and T5 treatments, while the highest titratable acidity was recorded in T4 and T5 treatments. In the sensory analysis, in juice with the highest percentage of ‘Bordô’ grape (T1 and T2) or with the same proportion of ‘Bordô’ and ‘Niágara Rosada’ (T3), the highest mean acceptance values were found. Thus, it could be concluded that the use of 100% ‘Bordô’ grape and ‘Bordô’ juice cut with up to 50% ‘Niágara Rosada’ are presented as alternatives for juice production.

Blueberry (Vaccinium spp.), much appreciated for its exotic flavor and nutraceutical properties, can be consumed in natura and in beverages such as nectar and juice. The aim of this study was to evaluate the chemical characteristics and the acceptance of commercial nectar and blueberry juice elaborated by the steam dragging method. The work was carried out in August of 2016, at the Universidade Federal de Pelotas, Pelotas (RS). The experimental design was in a uniform scheme, with two levels: commercial nectar and juice elaborated with the combination of fruits of cultivars Bluegem and Powderblue. Soluble solids content, titratable acidity and the pH of the samples were evaluated. For the sensorial analysis, a panel of fifty-five judges evaluated attributes such as color, aroma, flavor, body and global acceptance, using a nine-point hedonic scale. Regarding the chemical analyzes, there was a statistical difference for total soluble solids content and the nectar showed the highest content. In the sensory analysis, the juice elaborated with ‘Bluegem’ and ‘Powderblue’ obtained the highest mean for color, while for the flavor and body attributes, the preference of the judges for the nectar was verified. However, both had good overall acceptance, with scores between 7.52 and 7.62. Thus, acceptance of both nectar and juice was considered satisfactory by the evaluators.

Introdução: Uma das formas de consumo de frutas é na de suco in natura de preparação caseira, sem conservantes e muito consumidos e apreciados em todo o país. Objetivos: Avaliar as mudanças físico-químicas provocadas pelo tipo de armazenamento do suco de maracujá amarelo e do suco de goiaba ‘Pedro Sato’, durante de 48 horas após sua elaboração. Materiais e Métodos: Foram avaliadas quatro condições de armazenamento, em ambiente refrigerado (4 ±1° C) e em temperatura ambiente (22 ±1° C), ambas com e sem luminosidade. O experimento foi conduzido em delineamento inteiramente casualizado, com os tratamentos dispostos em esquema fatorial 2 x 2 x 6, sendo dois ambientes de luminosidade (presença e ausência), duas condições de temperatura (refrigeração e ambiente) e seis tempos de amostragem (0, 6, 12, 24, 36 e 48 horas) com três repetições. Foram analisados, pH, acidez titulável, sólidos solúveis, vitamina C total e cor utilizando-se as variáveis claridade (L*), ângulo de cor (ho) e cromaticidade (C*). Resultados: O tempo de armazenamento influencia negativamente na qualidade do suco de maracujá-amarelo de preparação caseira provocando o aumento do pH, conteúdo de sólidos solúveis e a diminuição dos teores de ácido cítrico e vitamina C, além de promover alterações na cor, principalmente na claridade e cromaticidade. Entretanto se armazenado em ambiente refrigerado e sem luz o suco conserva suas características iniciais por mais tempo. A exposição à temperatura ambiente tem influência sob as características químicas do suco de goiaba ‘Pedro Sato’ durante o armazenamento, principalmente na presença de luz, entretanto mesmo sofrendo influência desses fatores o suco de goiaba de preparação caseira apresentou considerável estabilidade físico-química ao longo do tempo. Conclusão: A exposição à temperatura ambiente e luminosidade tem influência sobre as características químicas dos sucos estudados. Introduction: In natura homemade juices are largely consumed and appreciated in Brazil. Objectives: In this work, physichal-chemical changes caused by the storage of homemade yellow passion-fruit juice and ‘Pedro Sato’ guava juice, over 48 hours after its preparation were evaluated. Materials and Methods: Four storage conditions were evaluated in a refrigerated environment (4 ±1° C) and in room temperature (22 ±1° C) both in the presence and absence of light. The experiment was conducted with a totally random design, with treatments arranged in a factorial 2 x 2 x 6, with two light conditions (presence and absence), two temperature conditions (cooling and room temperature) and six sampling times (0, 6, 12, 24, 36 and 48 hours) with three replicates. pH, titratable acidity, soluble solids, total vitamin C and color using the variables: luminosity (L*), hue angle (ho) and chromaticity (C*) were analyzed. Results: The storage time had a negative influence on the quality of yellow passion fruit or Pedro Sato guava juice causing the increase in pH, soluble solids content and the decrease in the levels of citric acid and vitamin C, and promotes changes in color, especially in clarity and chromaticity. However, if stored under refrigeration and without light juice retains its characteristics longer. Exposure to ambient temperature has an influence on the chemical characteristics of 'Pedro Sato' guava juice during storage, especially in the presence of light. However, even when influenced by these factors, guava juice from home preparation presented considerable physical- chemistry over time. Conclusion: Exposure to room temperature has an influence on the chemical characteristics of juices.

Facing the fruit market’s search for more efficient production systems, this research aimed to identify an arrangement of efficient irrigation systems for the productive and postharvest characteristics of ‘Kent’ mango fruits, under the conditions of the Brazilian semiarid. The research was performed in an agricultural property in the municipality of Petrolina-PE, with the soil classified in Quartzarenic Neosol. Four irrigation system arrangements were tested: a micro sprinkler below the canopy; a micro sprinkler between plants; two lateral dripper lines per row of plant; and a ring-shaped drip strip around the plant in a randomized block design with five repetitions. The productive characteristics were evaluated, such as number and average weight of fruits and productivity; and qualitative parameters (evaluated by plant quadrant): volume, density, firmness, soluble solids content and titratable acidity. A micro sprinkler between plants provided a greater number of fruits and productivity, as well as greater firmness and titratable acidity for mangoes of the South and West quadrants; these characteristics associated with the lowest soluble solids content of the pulp, at the time of harvest, was also obtained with a micro sprinkler between plants and induce a longer post harvest time to the fruits.

The research was done at Aleksandras Stulginskis University (Vytautas Magnus University Agriculture Academy since 2019) in 2017–2018. The research object was kombucha beverage brewed from Camellia sinensis L. black, green, oolong, pu-erh tea and fermented for 9 and 22 days by microorganisms at different room lighting conditions. The soluble solids content, active acidity and titratable acidity were determined in teas fermented for 22 days. The total amount of phenolics compounds, antioxidant activity, yeast colonies and sensory evaluation of tea were determined in teas fermented for 9 days. The research results showed that the quality of fermented tea was dependent on the tea species, but fermentation conditions were not essential. During the fermentation the soluble solids content of tea decreased by an average of 0.60% and the content of acetic acid increased by 0.34%. The highest content of acetic acid was found on the 22nd day of fermentation in all species of teas. The active acidity (pH) of all investigated species of teas decreased significantly during the fermentation process. The total content of phenolic compunds in all species of teas during the fermentation increased from 20 to 57% regardless of fermentation conditions. The highest content of total phenolic compounds was established in teas fermented for 9 days. The antioxidant activity of teas fermented for 9 days varied depending on the fermentation conditions. For black and green teas fermented in the light the antioxidant activity decreased, for oolong and pu-erh teas fermented in the dark the antioxidant activity increased. The number of yeast colonies increased in all tea samples during the fermentation. The best taste was fixed for pu-erh tea, which scored the highest (11.4) in sensory evaluation.

Brazil has a large variety of native and exotic fruit species, including the gabiroba, which can be sources of income for the population. The objective of this study was to evaluate the post-harvest behavior of gabiroba fruit by maturity stage and storage temperature. The fruits were divided into two lots and stored at temperatures of 6, 12, 24 and 30°C. The first batch was used for the physical and chemical analysis of acidity, soluble solids, firmness, percentage of green color, and visual analysis; this batch was composed of green and yellow-green fruit. The second lot was intended for breath analysis, composed of green, yellow-green, and yellow fruits. The experiment was conducted in a completely randomized design with five replications. Data were analyzed using descriptive statistics. Considering the evaluated characteristics, the gabiroba soluble solid/titratable acidity ratio values should be approximately 4.0 for the fruits to be considered acceptable for consumption. For the preservation of the post-harvest quality of gabiroba, it is indicated that the harvest is carried out at the green stage of maturation and that they are stored at a temperature of 6°C. The highest respiratory rates were observed in fruits harvested at the yellow stage, not being recommended its storage.

Abstract The study was conducted to determine the effects of Myrobalan rootstock and Blackthorn interstock on fruit physical and chemical traits of five apricot cultivars. The results showed that cultivars grafted on Myrobalan rootstock appear to induce a higher fruit mass when compared with the Blackthorn interstock. Blackthorn interstock showed a tendency to induce a higher soluble solids/titratable acidity ratio than Myrobalan. Values of soluble solids content, total sugars, titratable acidity and fruit firmness between Myrobalan rootstock and Blackthorn interstock were not significant. Regarding cultivars, the greatest fruit mass observed in Roxana in both treatments, and the lowest in Biljana on Myrobalan and in Vera on Blackthorn. The lowest soluble solids, total sugars and soluble solids/titratable acidity ratio were found in Roxana in both variants of grafting, whereas the greatest titratable acidity also observed in Roxana in both cases, respectively. Based on the results from this study, the fruits of Roxana can be recommended for fresh consumption, whereas fruits of the other cultivars can be recommended for processing.

Passiflora alata Curtis (sweet passion fruit) is a native species grown in South America, especially in Brazil. In addition to being aromatic, its pulp is sweeter and less acidic compared to traditional commercial passion fruits, and this makes it highly appreciated for fresh consumption. Its aroma is also very distinct from other passion fruit species but it has not been characterized so far. In the present study, for the first time, the volatile composition of sweet passion fruit was investigated. Two genotypes (BGM004 and BGM163) were evaluated and two SPME fibers were tested. Forty-five volatile compounds were properly identified and semiquantified. The carboxen-polydimethylsiloxane (CAR/PDMS) fiber presented better performance regarding both number and concentration of compounds. Esters and terpenes were the main volatile classes. Methyl butanoate, methyl (E)-2-butenoate, ethyl butanoate, ethyl (E)-2-butenoate, methyl 2-hexenoate, and ethyl-2-hexenoate were among major compounds. As complementary results, sugar content, titratable acidity, pH, and total soluble solids were evaluated.

The effects of prolonged ethylene exposure on external and internal quality parameters of tomato fruits were studied in order to explore the feasibility of its use as a nondestructive technique for screening immature and inferior quality fruit. `Agriset' and `CPT-5' tomatoes were hand harvested at Stage 1 (green) and held at 20°C and 50 ppm ethylene for 1-7 days. Each 24 hours, fruits reaching Stage 2 (breaker) were removed from C2H4 and transferred to 20°C air for subsequent ripening. Tomatoes were considered at edible maturity upon reaching full red-ripe stage and 4 mm deformation and final quality parameters were determined. For both cultivars, fruits which required prolonged C2H4 exposure to reach Stage 2 had lower overall visual appearance. `Agriset' tomatoes which required short exposure times to C2H4 (1 to 3 days) had somewhat higher quality than those requiring prolonged times (4 or 5 days). Days to reach edible maturity were 9.5 and 7.7, respectively. For the short exposure times, peel color was more intense (higher chroma value), while soluble solids content and total sugars were significantly higher (P = 0.05). Quality of `CPT-5' tomatoes was not adversely affected until requiring 6 or 7 days exposure to C2H4. Days to reach edible maturity decreased from an average of 12.5 to 11.0 for 1 to 5 or for 6 to 7 days exposure, respectively. For fruits requiring 7 days exposure, soluble solids content, total sugars and pH were significantly higher than for those reaching Stage 2 in fewer days. There were no significant differences in titratable acidity or ascorbic acid content for either cultivar.
