Este estudo teve como objetivo elaborar e caracterizar bebidas fermentadas de ata ( Annona squamosa L.), cirigüela ( Spondias purpurea L.) e mangaba ( Hancornia speciosa Gom.), utilizando leveduras comerciais. A partir das polpas dos frutos foram formulados mostos com teores de sólidos solúveis de 16 ºBrix. Esses foram inoculados com levedura seca ativa, estirpe S. cerevisiae var. bayanus e fermentados entre 18 e 21 ºC. Alíquotas dos mostos foram coletadas, diariamente, para monitoramento de pH, acidez titulável, teor de sólidos solúveis totais, açúcares totais e teor alcoólico. As bebidas obtidas foram avaliadas quanto às características químicas, físico-químicas e sensoriais. O mosto de ata apresentou fermentação rápida, atingindo estabilização dos teores alcoólico, sólidos solúveis e açúcares totais no sexto dia de fermentação, tendo o processo terminado no décimo segundo dia. A fermentação do mosto de mangaba foi relativamente rápida, com início da fase tumultuosa no terceiro dia e término do processo no décimo oitavo dia. O mosto de cirigüela apresentou fermentação lenta, estabilizou-se a partir do décimo dia com término do processo após o vigésimo dia. As bebidas atingiram teores alcoólicos de 8,4 ºGL (ata), 9,8 ºGL (mangaba) e 10,0 ºGL (cirigüela). Os resultados da análise sensorial demonstraram melhor desempenho da bebida fermentada de mangaba, tanto para a aceitação global quanto para a intenção de compra, sendo a mais indicada para a obtenção da bebida fermentada. TROPICAL FRUITS FERMENTED BEVERAGES Abstract This work had as objective to elaborate and characterize fermented beverages made from sugar apple ( Annona squamosa L.), red mombin ( Spondias purpurea L.) and mangaba ( Hancornia speciosa Gom.), by using commercial dry yeasts. Pulp fruits were used to formulate musts with soluble solids contents at 16 ºBrix. This were inoculated with the active dry yeast, S. cerevisiae var . bayanus and fermented at 18 to 21 ºC. Samples of musts were collected daily for monitoring pH, titratable acidity, total soluble solids content, total sugars and alcohol content. The obtained beverages were characterized by physical, chemical, physico-chemical and sensory analysis. The sugar apple must presented faster fermentation, reaching stabilization of alcohol, total soluble solids and total sugars contents in the sixth day of fermentation, being the process finished in twelve days. Mangaba must fermentation was relatively rapid, with tumultuous phase starting at the third day and finishing after 18 days. The slowest fermentation occurred in the red mombin must, which begun only after 10 days and finished after 20 days. Alcohol contents obtained were 8,4 ºGL (sugar apple), 9,8 ºGL (mangaba) and 10,0 ºGL (red mombin). Results from sensory analysis showed that mangaba fermented beverage was the most accepted as so in overall acceptance as in purchase intent test, indicating a promissory utilisation of this fruit.

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.

Pineapple is a food rich in vitamins, antioxidants and bromelain, but because it has high water content it becomes a highly perishable fruit. Hibiscus is a plant with flowers rich in phytochemicals that can be used as an ingredient to add value to processed products. The objective of this work was to prepare mixed jams using pineapple with hibiscus extract at different concentrations and to characterize the physicochemical properties of the jams produced. Experimental design was completely randomized with four replicates. The treatments consisted of three concentration levels of hibiscus extract (5, 10 and 15%) in pineapple jelly (50:50). Analyzed physical-chemical characteristics were: water content, water activity, ash, lipids, total sugars, reducing and non-reducing sugars, vitamin C, total titratable acidity, pH and total soluble solids. It was found that increasing concentrations of hibiscus in the formulations significantly influenced resulting jam composition. Increasing hibiscus concentration reduced the total sugars content and increased ascorbic acid content, acidity, total soluble solids and ash, as well as total anthocyanins and flavonoids contents. Among the jams produced, the formulation with 15% hibiscus was distinguished by its high content of ascorbic acid, flavonoids and anthocyanins. The addition of hibiscus to pineapple jelly improves the nutritional and functional value of the resulting jams, so it can be considered a high potential ingredient for this type of product.

ABSTRACT: Soursop is a well-appreciated tropical fruit, both in natura and in the form of juices and nectars. Despite its wide acceptance, there is lack of its use in the preparation of other products, such as alcoholic beverages. The objective of this study was to prepare soursop liquors by varying the concentrations of pulp and sucrose syrup with different contents of total soluble solids and to evaluate the effects of these on the physical and chemical characteristics of the beverages. In the production process, the pulp (300, 400 and 500 g) was macerated with distilled alcohol for 20 days, after which it was filtered, added to the syrup (50, 60 and 70 °Brix), bottled in polyethylene bottles and subjected to an accelerated aging. All drinks resulted in alcohol levels (15.25 to 16.69% v/v) and total sugars (12.63 to 17.97%) in accordance with the standards required by law. The experiments made with the lowest concentration of pulp showed the highest yields (84.17 and 85.25%). First-order models with interactions and 95% confidence intervals were obtained. The pulp consisted of the most significant factor, influencing the largest number of responses (yield, alcohol content, dry residue, titratable acidity, titratable acidity/soluble solids ratio and luminosity). The larger coefficient of determination (R2) values were found in the models adjusted to the data of yield, dry residue, total soluble solids, titratable acidity and total sugars, which were significant and predictive, showing values greater than 0.97.

Fruits of five regional selections of rambutan (Nephelium lappaceum L.) were characterized to identify those with international marketing quality to promote their propagation in Mexico, improvement and conservation in germoplasm bank. The fruits were harvested in June, July, and August 2008 and, after each harvest, were assessed for shape (length/diameter), firmness, fruit weight, number of fruits per kilogram, weight and percentage of pericarp, seed and aril, total soluble solids, total sugars, vitamin C content, pH, and titratable acidity. In addition, a sensorial evaluation was carried out with 31 panelists who graded each selection for color, sweetness, and acidity. Fruits of five selections were ovoid, and with the following characteristics: firmness values from 43.7 to 51.0 N, fruit weight ranged from 22.4 to 34.7 g, registering from 28.9 to 45.0 fruits per kg; pericarp weight from 10.5 to 17.3 g (45.9 to 49.9% of the total fruit weight); total seed weight from 2.2 to 2.5 g (7.0 to 10.0%); average arils weight from 8.9 to 13.1 g (37.5 to 41.4%). The fruits had high contents of total soluble solids (17.8 to 20.4 ºBrix), total sugars (211.95 to 242.70 mg/100g in the edible portion), vitamin C (37.9 to 69.1 mg/100 g), pH 5.0, and titratable acidity of 0.20 to 0.28%. The fruits from the RT-01 and RT-05 selections had better attributes in fruit weight, total soluble solids and titratable acidity and were better accepted by the panelists. Harvest date significantly affects rambutan fruit quality; at the middle and end of the season harvested fruits had better qualitative characteristics for the marketing.

Volatile Aroma Compounds

An attempt was made to understand the changes in physicochemical quality (total soluble solids, titratable acidity, ascorbic acid, total sugars, total phenolics, anthocyanin content, and cupric reducing antioxidant capacity assay) and total volatile/aroma compounds of two cultivars of strawberry (Camarosa and Chandler) during storage at 5°C for 9 days at an interval of three days. Observations indicated a significant quantitative difference both in the physicochemical and in total volatile content among the cultivars indicating the importance of cultivar for determining the postharvest quality and shelf life. At the end of 9 days of storage significant changes in the physicochemical and total volatile/aroma compounds were observed. Total antioxidants and total phenols were found to increase significantly, whereas total soluble solids and total sugars decreased with the advent of storage period for both cultivars. Total anthocyanin contents however remained almost constant throughout the storage period. Titratable acidity in Camarosa reduced with the increase in the storage period whereas it remained almost constant in Chandler. Ascorbic acid increased in Camarosa whereas the same decreased significantly in Chandler. Significantly higher contents of esters and terpenoids in Camarosa indicated a better retention of the typical fruits flavour of strawberry compared to that of Chandler.

O presente trabalho visou avaliar formulações de néctares de frutas (araçáboi, ata, cajá, camucamu, ciriguela, mangaba e sapoti) nativas das regiões Norte e Nordeste do Brasil. As formulações foram desenvolvidas a partir da polpa dos frutos, empregandose de 30 a 35% de polpa, conforme as características de sabor e aroma. Para cada fruto foram testados dois níveis de sólidos solúveis, variando de 12 a 16 ºBrix, ajustados com adição de sacarose. Os frutos que apresentaram baixos níveis de acidez tiveram seus néctares corrigidos com adição de ácido cítrico, de maneira que a acidez ficasse entre 0,25 e 0,30%. As formulações foram avaliadas por meio de análises de pH, acidez total titulável, vitamina C, açúcares solúveis totais e redutores, sólidos solúveis totais, razão ºBrix/acidez e análise sensorial. De forma geral, somente os sólidos solúveis totais e os açúcares totais apresentaram diferenças estatísticas entre as formulações de cada fruta, o que se justifica pela adição de sacarose no desenvolvimento das formulações. A relação ºBrix/acidez mantevese na faixa de 20 a 60 para todos os néctares. Os maiores níveis de vitamina C foram encontrados nos néctares de camucamu (455,2 e 470,5 mg/ 100 g) e mangaba (48,4 e 52,7 mg/100 g), enquanto os demais apresentaram níveis inferiores a 20 mg/100 g. A exceção do camucamu, todos os atributos sensoriais para os outros néctares receberam notas superiores a 6,0. Os resultados preliminares evidenciaram boa aceitação e possibilidades promissoras no aproveitamento dos frutos. Abstract This work aimed to evaluate nectar formulas from tropical fruits (aracaboi, sugar apple, red mombin, camucamu, yellow mombin, mangaba, sapoti) indigenous of North and Northeast regions of Brazil. The formulations were developed from fruit pulp using 30 to 35% according to their flavor and aroma characteristics. For each fruit two levels of total soluble sugar were used ranging from 12 to 16 ºBrix and adjusted by sucrose addition. Citric acid was added in fruits nectars which had low acidity in order to reach 0.25 to 0.30% acidity. Samples were evaluated by analysis of pH, titratable acidity, total soluble solids, ºBrix/acidity ratio, vitamin C, total sugars, reducing sugars and sensory analysis. Only total soluble solids and total sugars showed statistical differences among formulations for each fruit, due to sucrose addition during nectars preparation. ºBrix/acidity ratio ranged from 20 to 60 for all nectars evaluated. Vitamin C highest levels were observed for camucamu (455.2 and 470.5 mg/100 g) and mangaba (48.3 and 52.7 mg/100 g) nectars. Excluding camucamu, all sensory scores for fruit nectars were higher than 6.0. Results showed good acceptability of fruit nectars and possibilities for industrial processing.

High Density Linkage Map

AbstractFruit quality traits play a significant role in consumer preferences and consumption in blueberry (Vaccinium corymbosum L). The objectives of this study were to construct a high-density linkage map and to identify the underlying genetic basis of fruit quality traits in blueberry. A total of 287 F1 individuals derived from a cross between two southern highbush blueberry cultivars, ‘Reveille’ and ‘Arlen’, were phenotyped over three years (2016–2018) for fruit quality-related traits, including titratable acidity, pH, total soluble solids, and fruit weight. A high-density linkage map was constructed using 17k single nucleotide polymorphisms markers. The linkage map spanned a total of 1397 cM with an average inter-loci distance of 0.08 cM. The quantitative trait loci interval mapping based on the hidden Markov model identified 18 loci for fruit quality traits, including seven loci for fruit weight, three loci for titratable acidity, five loci for pH, and three loci for total soluble solids. Ten of these loci were detected in more than one year. These loci explained phenotypic variance ranging from 7 to 28% for titratable acidity and total soluble solid, and 8–13% for pH. However, the loci identified for fruit weight did not explain more than 10% of the phenotypic variance. We also reported the association between fruit quality traits and metabolites detected by Proton nuclear magnetic resonance analysis directly responsible for these fruit quality traits. Organic acids, citric acid, and quinic acid were significantly (P < 0.05) and positively correlated with titratable acidity. Sugar molecules showed a strong and positive correlation with total soluble solids. Overall, the study dissected the genetic basis of fruit quality traits and established an association between these fruit quality traits and metabolites.

ABSTRACT: Dehydration is an important alternative to making the most of the use the surplus of production and take advantage of the seasonality of tropical fruits. Thus, this study aimed to evaluate the physicochemical composition of the yellow mombin pulp (Spondia mombin L.) powder, obtained by spray drying, and evaluate its sensory acceptance in the form of reconstituted juice. The physicochemical analyzes of the yellow mombin powder were: pH, soluble solids, titratable acidity, ascorbic acid and moisture, with all results in accordance with the current legislation. The addition of maltodextrin in the process reduced the sensory analysis values (color, appearance, and taste). The tested formulations, (powders with 25 and 27.05% maltodextrin) preserved, and even favored the aroma. These formulations had the following values (7.66 and 7.68) higher than the values found for integral juice (6.60).

Hancornia speciosa is a fruit tree, popularly known as mangabeiras. The mangaba, fruits of this tree, are quite appreciated for their organoleptic characteristics. Because it is a climacteric fruit, this fruit has very high perishability. The use of products that extend the useful life is necessary. Calcium chloride (CaCl2) has been shown to be an alternative in post-harvest because it promotes few changes in fruit quality and increases the storage period. Thus, the objective of this work was to evaluate quality attributes of mangaba fruits in two stages of maturation, 'Immature' and 'Mature', submitted to CaCl2 application, in four storage times (0, 2, 4 and 6 days) under ambient atmosphere. During the experiment, the loss of fresh weight, color, pH, titratable acidity, soluble solids and SS/TA ratio were evaluated. It was verified that the 'mature' fruits showed a higher acidity and soluble solids content, even with the application of CaCl2, the difference that the loss with the application of CaCl2 was smaller. Unlike '‘Immature’ and ‘Immature’ fruits with CaCl2 in which these characteristics were acquired as the experiment was conducted, in addition to presenting lower values for weight loss, pH and color.
