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.

Este trabalho teve por objetivo a avaliação físico-química e sensorial de diferentes albedos cítricos, processados de maneira artesanal na forma de compotas e de produtos cristalizados. As compotas analisadas apresentaram diferença significativa, principalmente, nos valores de pH, sólidos solúveis totais e vitamina “C”. Nos produtos cristalizados, as principais diferenças ocorreram nos teores de sólidos solúveis totais, acidez total titulável e vitamina “C”. Nos testes de preferência, tanto a compota quanto o produto cristalizado, elaborados com o albedo de Citrus karnas atingiram maiores médias. Conclui-se que a elaboração de compostos com albedos críticos exige que as matérias-primas sejam testadas, pois respondem de maneiras diferentes quando submetidas ao mesmo processo. Dentre as espécies estudadas, os albedos de Citrus karnas obtiveram melhor desempenho nos testes sensoriais e exigiram menor tempo de secagem. A manutenção dos albedos durante quatro dias em solução de NaCl não foi suficiente para a remoção de naringina, sendo necessário prolongar ou revisar essa etapa do processo. A opção pela fermentação como pré-tratamento das cascas poderá conferir ao produto cristalizado textura mais macia. STUDY OF CRYSTALLIZED FRUITS AND PRESERVES ELABORATED WITH DIFFERENT CITRIC ALBEDOS Abstract This work had as objective the physical-chemical and sensorial evaluation of different citric albedos, processed in a crafty matter, in the form of fruit preserves and of dried crystallized products. The analyzed fruit preserves presented significant difference, mainly, in the pH values, total soluble solids and vitamin “C”. In the crystallized products, the main differences occurred in the contents of total soluble solids, total titratable acidity and vitamin “C”. In the preference test, the fruit preserve as well as the crystallized products elaborated with Citrus karnas albedo, reached the highest averages. In conclusion, there is a need to test raw materials once they respond differently when submitted to the same process. Among the studied species, the albedos of Citrus karnas obtained better acting in the sensorial tests for fruit preserves and crystallized products. Besides it requests smaller drying time. The maintenance of the albedos for four days in NaCl solution was not enough for the naringina removal, being necessary to prolong or to revise that stage of the process. The option for the fermentation as pre-treatment of the peels can confer to the crystallized product softer texture.

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.

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.

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.

The experiment of the present research work was conducted during summer season of 2018-19 and 2019-20 at Horticulture Research Farm-I, Department of Horticulture, School of Agricultural Sciences and Technology, Babasaheb Bhimrao Ambedkar University (A Central University), Vidya-Vihar, Rae Bareli Road, Lucknow (U.P.), India. The analysis of variance clearly reveals significant differences among the genotypes for all characters. The observations recorded on various characters showed that the estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient variation (GCV) for all characters. The high phenotypic as well as genotypic coefficient of variation were observed in marketable fruit yield per plant (39.36%) followed by average fruit weight (29.73%) and number of branches per plant (27.18%). High estimates of heritability were recorded for different characters viz., average fruit weight (98.6%) followed by total soluble solids (97.8%), total sugars (97.7%) and days to anthesis of first pistillate flowers (97.2%). The parameters which observed were found to be very high estimate value of genetic advance in per cent of mean of (60.14%) average fruit weight (60.14%) followed by titratable acidity (53.73%), number of branches per plant (53.47%), total soluble solids (52.81%) and marketable fruit yield per plant (47.87%).

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 The demand for organically grown products is increasing because many people are concerned about the environment and believe that organic products are healthier than conventional ones. Some studies have shown that organically produced tomato fruits contain higher levels of antioxidants, polyphenols and carotenoids than those produced conventionally. The objective of this study was to evaluate the influence of organic and inorganic fertilization on agronomic and quality characteristics of the processing tomato. The 2-year experiment was laid out in a randomized complete block design, with three replications and three fertilization treatments (untreated, compost and inorganic fertilizer). The results showed that the highest fruit number per plant (98.5), average fruit weight (63.6 g) and fruit yield (168.0 t ha−1) were obtained under inorganic fertilization. The highest total soluble solids (4.39 °Brix) and total soluble solids to titratable acidity ratio (17.4), L* (43.4) and a* (35.4) values, as well as the highest lycopene content (88.5 mg kg−1 f.w). were achieved through the application of organic fertilizer. Significantly higher total soluble solids and total soluble solids to titratable acidity ratio in organically grown tomatoes are particularly important to the processing tomato industry. Finally, the highest lycopene content produced under organic fertilization as well as the non-significant difference between the organic and conventional tomatoes in terms of lycopene yield make organic processing tomatoes suitable for lycopene production.

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.

Abstract The experiment was carried out in the Garlica Murowana Experimental Station of University of Agriculture in Krakow, Poland, between 2005 and 2008. Fruit yield, mass of 100 berries, content of total soluble solids, vitamin C, anthocyanins and titratable acidity were estimated. It was shown that ‘Atut’ honeysuckle started vegetation, flowering and cropping periods earlier than ‘Duet’. However, greater marketable yield and mass of 100 berries were obtained for ‘Duet’. ‘Atut’ fruit revealed a significantly higher content of anthocyanins. The studied honeysuckle cultivars did not differ if estimated on the basis of total soluble solids and vitamin C content in the fruit.

Fifty-six accessions of white sapote (Casimiroa edulis Llave & Lex.) grown in situ in 11 municipalities in the state of Michoacán, Mexico, were characterized using 14 morphometric variables (six of fruit and eight of seed). There was a high cv for fruit weight (0.50), the number of developed seeds (NDS) (0.48), and total seed weight (0.45). Principal component analysis (PCA) showed that the main differences among the C. edulis accessions were fruit weight, seed projected area, Feret diameter (FD), the length of polar and equatorial axes of the fruit, the number of undeveloped seeds (NUS), the NDS, hardness of the skin (HS), and total soluble solids content of the fruits. Three groups of accessions were determined by cluster analysis (CA). The first group was made up of 53 accessions with intermediate values of fruit size and seed size. The second group, comprising two accessions, had the lowest values of fruit size. The third group showed an outstanding individual with the highest values for fruit size/weight, seed weight, and total soluble solids. Through an in-depth examination of the genotypes of the first group, four genotypes were identified for their positive characteristics. The results indicate an extremely high variability in the fruit and seed characteristics produced by different trees/genotypes of white sapote in Mexico. Hence, an initial, preliminary individuation/selection of five genotypes could be considered for the development of new cultivars for establishing white sapote orchards in Mexico.
