ABSTRACT This study aimed to evaluate the physico-chemical composition of native fruits of the Ceará coast at different development stages. The fruits of ‘guajiru’, ‘manipuçá’, ‘murici-pitanga’ and ‘murta’ were collected during the year 2014, and the following evaluations were made: total soluble solids, total titratable acidity, pH, total soluble solids and titratable acidity ratio. A completely randomized design was used, with 5 or 6 treatments, depending on the maturation stage and 4 replicates. For total soluble solids, ‘murta’ obtained a minimum of 2.6 °Brix in stage 1 and ‘manipuçá’ obtained maximum of 24.53 °Brix in stage 5. For the total titratable acidity, ‘guajiru’ showed minimum of 0.09% in stages 3 and 4, and ‘murici-pitanga’ showed maximum of 3.29% in stage 6. ‘Murici-pitanga’ had minimum pH of 3.44 in stage 5 and ‘guajiru’, maximum pH of 5.9 in stage 2. For total soluble solids and titratable acidity ratio, ‘murici-pitanga’ exhibited a minimum of 3.25 in stages 1 and 3, and ‘guajiru’ showed maximum of 141.11 in stage 4. It was concluded that ‘guajiru’ and ‘manipuçá’ fruits reached physiological maturity in stage 3, whereas ‘murici-pitanga’ and ‘murta’ fruits reached in stage 4; thus, these are the ideal stages for fruit harvest.

E-mail: [email protected]     1 RESUMO   Devido suas propriedades medicinais e por ser um alimento rico em antioxidantes, o consumo da hortaliça berinjela vem crescendo. Durante o cultivo da berinjela, o manejo da água e do solo são fatores que podem influenciar a qualidade do fruto. Assim, objetivou-se com este trabalho analisar as características físico-químicas do fruto da berinjela ‘Florida Market’ irrigada com águas salobras por gotejamento contínuo e pulsos. O experimento foi conduzido em ambiente protegido com delineamento experimental em blocos casualizados, em esquema fatorial 2 x 4, com cinco repetições. Os tratamentos consistiram de duas formas de aplicação de água: gotejamento contínuo e pulsos, com quatro níveis de condutividade elétrica da água – CEa (0,3 (controle); 1,5; 3,0 e 4,5 dS m-1). Foram avaliadas as variáveis: massa fresca do fruto, teor de sólidos solúveis totais, pH da polpa, acidez total titulável e relação sólidos solúveis totais/acidez total titulável. Com o incremento da salinidade da água de irrigação o teor de sólidos solúveis totais (+3,60%) e acidez total titulável (+9,87%) aumentaram, enquanto a relação de sólidos solúveis totais/acidez total titulável (-4,53%) e a massa fresca do fruto diminuíram. A interação entre a salinidade e a forma de aplicação da água não influenciou as características físico-químicas do fruto.   Palavras-chave: Solanum melongena L., salinidade, sólidos solúveis, acidez titulável.     DAMASCENO, L.

Os atributos físicos e químicos da acerola podem sem influenciados por vários fatores: genótipo, localização do pomar, tratos culturais empregados nas plantas, índice pluviométrico, irrigação, exposição à luz solar, estádio de maturação dos frutos e época de colheita. O presente trabalho avaliou características químicas e físico-químicas de frutos de diferentes genótipos de aceroleira em duas épocas de colheita. A primeira época no período de fevereiro a março de 2014, e a segunda época de dezembro de 2014 a janeiro de 2015. Os materiais genéticos avaliados foram Olivier, BRS 237 - Roxinha, BRS 236 - Cereja, BRS 238 - Frutacor, BRS 235 - Apodi, Waldy – CATI 30 e Okinawa. O delineamento utilizado foi o inteiramente casualizado (DIC) em esquema fatorial, com 7 cultivares em 2 épocas de colheita, totalizando 14 tratamentos, e a repetição sendo 500 g por amostra de frutos maduros para cada genótipo de aceroleira representado por oito plantas em fase de produção e com oito anos de idade. Avaliaram-se os seguintes atributos físico-químicos: pH e sólidos solúveis (°Brix), e químicos: ácido ascórbico, e acidez titulável (expressa em g de ácido cítrico 100 g-1 de polpa). Também foi determinada a relação °Brix / Acidez titulável. Nas duas épocas de colheita avaliadas, a composição da acerola é mais influenciada pelo genótipo que pelas condições climáticas de precipitação e temperatura do ambiente. Todos os clones de aceroleira atendem a legislação brasileira vigente quanto à qualidade de polpa de fruta de acerola.Palavra-chave: Malpighia emarginata Sessé e Mociño ex DC, qualidade, fruticultura tropical. COMPOSITION OF THE ACEROLA OF DIFFERENT GENOTYPES IN TWO SEASONS OF HARVEST ABSTRACT:The physical and chemical attributes of acerola can be influenced by several factors: genotype, orchard location, crop management, pluviometric index, irrigation, exposure to sunlight, fruit maturation stage and harvest season. The present work evaluated the chemical and physical-chemical characteristics of the acerola of different genotypes at two harvest seasons. The first time in the period from February to March 2014, and the second time from December 2014 to January 2015. The genetic materials evaluated were Olivier, BRS 237 - Roxinha, BRS 236 - Cherry, BRS 238 - Frutacor, BRS 235 - Apodi, Waldy - CATI 30 and Okinawa. The design was a completely randomized design in a factorial scheme, with 7 cultivars in 2 seasons of harvest, totaling 14 treatments, and the repetition being 500 g per sample of mature fruits for each genotype of acerola represented by eight plants in production and eight years of age. The following physico-chemical attributes were evaluated: pH and soluble solids (° Brix), and chemicals: ascorbic acid, and titratable acidity (expressed in g of citric acid 100 g-1 of pulp). The ratio ° Brix / Titratable acidity was also determined. In the two evaluated harvest periods, the composition of the acerola is more influenced by the genotype than by the climatic conditions of precipitation and temperature of the environment. All clones of acerola are in compliance with the Brazilian legislation in force regarding the quality of fruit pulp of acerola.Keywords: Malpighia emarginata Sessé e Mociño ex DC, quality, tropical fruticulture. DOI:

The objective of this work was to perform the physical-chemical characterization of different formulations of the pequi pulp with the addition of different concentrations of whole milk, in order to identify promising products for commercial use. Three formulations of pequi pulp with whole milk were prepared: PL1- 90% pequi pulp and 10% milk, PL2 - 70% pequi pulp and 30% milk, PL3 - 50% pequi pulp and 50% milk. The formulations were evaluated for physical and physical-chemical parameters of color, water activity, water content, ash, total soluble solids (SST), pH, total titratable acidity (ATT), SST/ATT ratio, ascorbic acid, proteins, lipids, total, reducing and non-reducing sugars. The data obtained were subjected to analysis of variance (ANOVA) and comparison between means by the Tukey test at 5% probability. Among the three tested formulations, the best results were obtained for PL3, where it presented lower total titratable acidity, water activity, red intensity, yellow intensity and chromaticity, however, higher content of total soluble solids, ratio SST/ATT, ash, lipids, sugars (total, dimmer and non-dimmer), luminosity and tint angle. The inclusion of milk in the pequi pulp changed the physical and physical-chemical characteristics of the pulp, and it can be an alternative to add nutritional value to the fruit and consequently a promising product for the market.

ABSTRACT This work evaluated the effects of ionizing radiation on the physico-chemical and sensory characteristics of the potato cultivar Ágata (Solanum tuberosum L.), including budding and deterioration, with the end goal of increasing shelf life. For this, four groups of samples were harvested at the maturation stage. Three of them were separately exposed to a Co-60 source, receiving respective doses of 0.10, 0.15 and 2.00 kGy, while the non-irradiated group was kept as a control. All samples were stored for 35 days at 24 °C (± 2) and at 39% relative humidity. The following aspects were evaluated: budding, rot, loss of weight, texture, flesh color, moisture, external and internal appearance, aroma, soluble solids, titratable acidity, vitamin C, protein, starch and glucose. The results indicated that 0.15 kGy was the most effective dose to reduce sprouting and post-harvest losses, under the conditions studied.

Effects of enriching soymilk with pawpaw puree at different ratios (10 – 40%) were evaluated for physicochemical properties, vitamin A and C, mineral contents, and sensory attributes. The results showed increase in total soluble solids (5.5 – 8.5 oBrix), total titratable acidity (0.53 – 0.87 g/kg) and viscosity (19.9 – 26.7 cp), but decreased in pH (7.4 – 6.8). Vitamin A and C contents of the soy-pawpaw beverage increased from 12.4– 20.4 μg/100 ml and 10.9 – 25.8 mg/100 ml, respectively. All the macromineral contents of the enriched soymilk beverages increased significantly except for sodium.Enrichment of soymilk with pawpaw puree improved the sensory attributes of the drink in terms of flavour, taste, mouthfeel and overall acceptance, especially at high supplementation level (40%). Soymilk with pawpaw puree resulted in products with better vitamin A and C and macro-mineral contents than plain soymilk drink, thus, the soy-pawpaw beverage will complement consumers micro and macro-nutrient intake.

Abstract: The objective of this work was to evaluate the influence of fig (Ficus carica) cultivars grown in subtropical regions on the physicochemical, rheological, and sensorial characteristics of the canned figs. Fresh fruits of the cultivars were analyzed for length, diameter, unit mass, total soluble solids, total titratable acidity, pH, total soluble solids/total titratable acidity ratio, and color. Canned figs were evaluated for titratable acidity, pH, color, texture profile, and sensory characteristics. The different physicochemical characteristics of the fresh figs influenced those of the obtained canned fruits. The canned figs from 'Lemon' and 'Pingo de Mel' presented the lowest and highest pH, respectively, whereas those from 'Troiano' showed the highest total titratable acidity. As for color, after processing, the canned figs, in general, presented a more greenish and darker color than the fresh fruits. The canned figs from 'Brunswick' and 'Troiano' had the lowest acceptance, whereas those from 'Bêbera Branca' and 'Roxo de Valinhos', the greatest. Less acid and softer canned figs are more widely accepted, which can be obtained from all cultivars, except from Brunswick and Troiano.

Early Harvest

Carambolas (Averrhoa carambola L., cv. Arkin) ware harvested at colorbreak (CB) and light green (LG) ripeness stages, commercially packed and cooled. The next day the fruit were treated as: Control (ungassed): CB, LG; Ethylene pretreatment (ETH) @100ppm: LC for 1, 2 or 3 days at 20°C or 25°. After pretreatment the fruit were stored at 5°. After 1, 2, 3, 4 weeks, 10 fruit from each treatment ware removed from storage and placed at 20°. Fruit color and decay were rated daily until 80% of the fruit in each treatment reached the yellow ripeness stage, at which time external color, total soluble solids (TSS), pH and total titratable acidity (TTA) were determined. Carambolas harvested at the LG stage can be ripened to good quality with ETH pretreatment. For two weeks storage at 5°, 2 days ETH are necessary at 20° or 25° to initiate ripening. For three weeks storage, 3 days ETH are required at 20°, and 2 or 3 days ETH are required at 25°. Fruit stored four weeks were of fair quality. LG with slower ripening initiation developed chilling injury during storage; the fastest initiation had the best color but the shortest marketing life. Fruit harvested CB had slightly higher TSS than ETH-treated LG but pH and TTA were similar.

Surveys carried out in different microregions of Maranhão highlight papaya as one of the fruits with the postharvest losses estimates. In this context, this study aimed to analyze the efficiency of plastic packaging on postharvest conservation of Hawaii papaya to instruct the Maranhão retail market about viable alternatives to mitigate losses related to this fruit. The papayas were purchased from CEASA of São Luís and sent to the laboratory. Posteriorly, they were randomly separated into 65 groups of 2 units, and then, applying the coverings are made. The experimental design was completely randomized in a split-plot at 4x5 times, with four treatment control [(without packaging), plastic film (FP), hermetic-bag (SH), and perforated-bag (SP)] and five evaluation periods (3, 6, 9, 12, and 15 days of storage); four repetitions and 2-fruits per portion (tray). For the individual biometric characterization, was carried out the measuring of the longitudinal and transverse diameters, fresh mass, pulp yield, seed mass, firmness, and fruit mass loss. Furthermore, for chemical analysis, total soluble solids content, total titratable acidity, and pH were measured. It was found, at the end of the study, that the hermetic-bag is efficient for maintaining the loss of fresh mass, firmness, ripening, total soluble solids content, total titratable acidity, and pH, which are relevant attributes of quality for commercialization of the Hawaii papaya. Therefore, the use of the hermetic-bag is recommended to increase the postharvest shelf life of Hawaii papaya fruit under stored at room conditions and at least for 15 days.

Abstract Objectives Tomato is a popular fruit that makes significant contributions to human nutrition for its content of sugars, acids, vitamins, minerals, lycopene, and other constituents. The fruit, however, has a short shelf life due to its climacteric nature. In view of this, an experiment was conducted to determine the effect of postharvest treatment on the physicochemical properties of fresh tomato fruits. Materials and Methods Freshly harvested tomato fruits were subjected to 0, 1, 2, 3, and 4 kGy gamma radiation and stored at 10 ± 1°C and 28 ± 1°C. Parameters analysed during the study include pH, total titratable acidity, weight loss, total solids, and moisture content of the sample. Results At both storage temperatures, results of the analyses were in the range of 2.80%–38.67% for weight loss, 0.23%–0.51% for total titratable acidity, 3.5%–5.0% for total soluble solids, 94.43%–96.53% for moisture content, and pH was generally low in the samples stored at 10 ± 1°C. Generally, gamma irradiation had an effect on the total soluble solids, total titratable acids, pH values, and moisture content and physiological weight loss at both storage temperatures. Conclusion From the study, storing Burkina variety at a low temperature preserves the tomato fruits better than storing them at ambient temperature.
