ABSTRACT Blackberry has the potential to be grown in subtropical climates, requiring phenological studies for the indication of cultivars adapted to this type of climate. Thus, the aim of this work was to evaluate the phenological behavior of four blackberry cultivars, as well as to determine the physical and chemical characteristics of fruits produced in mesothermal subtropical climate (Cfa), with more focus on the recommendation of cultivars adapted to this region. The largest production cycle and the best productions and yields were obtained for Guarani cultivar and larger fruits were presented by Tupy cultivar. The best relationship between titratable acidity and soluble solids was presented by Cherokee cultivar.

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.

<p>The current study deals with <em>cacha&ccedil;a</em> irradiation in the presences of grapes, with the use of gamma radiation (Co 60) to evaluate its effects on the physical and chemical characteristics of this beverage. The research had as objective to assess the effects of irradiation in <em>cacha&ccedil;as</em>, in the extraction of compounds present in the pickled grapes in the <em>cacha&ccedil;a</em>. Samples were prepared with grapes type Crimson, in polypropylene bottles, with and without grapes. Both types of samples were irradiated with doses of 0 (control) and 300Gy. Later were performed physical and chemical analyzes (pH, titratable acidity, soluble solids) during a 5-day span after irradiation treatment. Significative statistical difference was noticed in titratable acidity of the samples that contained grapes, larger values when compared with pure samples. However, there was no statistical difference when comparing the pure beverage with control or the beverage containing grapes and control. For pH the values for the samples with grapes is statistically lower than the others. The results for soluble solids (&ordm;Brix) displayed an increase on both types of samples comparing with their respective controls. In conclusion, the 300Gy dose was effective for increasing soluble solids quantity both in pure <em>cacha&ccedil;as</em> as in presences of grapes. Relating to pH and acidity, this dose shows interference when grapes are presents.</p><p>&nbsp;</p><p>DOI: 10.14685/rebrapa.v6i1.199</p>

The fruit physical and chemical characteristics can vary during the maturation period and this variation depends, among other factors, on the weather conditions during fruit development. This study aimed to evaluate the changes in physical and chemical characteristics of eight peach cultivars during two seasons. The cultivars Campinas 1, Coral, Maciel, Marli, Premier, Regis, Rei da Conserva and Tropic Beauty were planted on Okinawa rootstock at the experimental orchard of the Federal University of Viçosa (UFV), Viçosa-MG, Brazil, in 2008 and the following characteristics were evaluated: fruit weight, skin color, firmness, soluble solids, titratable acidity, ascorbic acid and total carotenoids. The experiment was conducted during 2011 and 2012 growing seasons in a completely randomized design with eight treatments (cultivars), three repetitions and 10 fruits per plot. There were differences between the variables for the two seasons, with the largest variations observed for firmness, ascorbic acid and total carotenoids. Cultivars Maciel and Marli produced fruit with higher mass, Tropic Beauty with greater firmness and Rei da Conserva, Coral and Marli with higher soluble solids contents. The cultivar Rei da Conserva presented higher values for most of the evaluated variables in both seasons. The yellow color, evaluated by the hue angle, is associated with total carotenoids content in peaches.

Abstract By considering the few studies related to pineapple cv. Vitória, to know the relationships between the physical and chemical characteristics of the fruits, and they with the “D” leaf, is fundamental. The objective of this work was to evaluate the relationships between “D” leaf, with the physical and chemical characteristics of fruits of pineapple cv. Vitória, under the edaphoclimatic conditions in the North of the State of Espírito Santo. The experiment was carried out in a complete randomized block design in split-plot arrangement with four replications. The data obtained from 433 individually evaluated fruits were analyzed, as it follows: 84 at planting in July and induction at 8 months; 98 at planting in July and induction at 10 months; 84 at planting in July and induction at 12 months; 59 at planting in September and induction at 8 months; 50 at planting in September and induction at 10 months; 58 at planting in September and induction at 12 months. Pearson’s correlation was performed between the characteristics of “D” leaf (length and width) and the physical and chemical aspects of fruits (mass of the fruits with and without crown, fruit length and diameter, pulp volume, translucent area, soluble solids and titratable acidity) for the six treatments. Most of the relationships among the 11 characteristics evaluated were of low magnitude in the six treatments, but correlations of high magnitude and practical application of interest to plant scientists, breeders, farmers and consumers were found. The length and width of the “D” leaf should not be used as indicators of physical and chemical qualities of cv. Vitória. Fruits with higher mass, with or without crown or larger width or diameter present higher pulp content. Fruits with higher mass, with or without crown have lower content of soluble solids.

<p>Este trabalho teve como objetivo avaliar os parâmetros físico-químicos de polpas de fruta produzidas e comercializadas na cidade de Petrolina-PE, tendo como referência a Instrução Normativa nº 1, de 7 jan. 2000, do Ministério da Agricultura que define as características físicas e químicas estabelecendo limites mínimos e máximos específicos para cada polpa de fruta. Foram avaliadas duas marcas (1 e 2) de polpas de abacaxi, cacau, caju, graviola, maracujá e umbu, analisadas quanto aos parâmetros de pH, sólidos solúveis totais (SST), acidez total titulável (ATT), ácido ascórbico, relação SST/ATT e sólidos totais. Os resultados permitem inferir que a marca 2 apresentou qualidade superior na maioria dos parâmetros avaliados quando comparado com a marca 1. Entretanto para alguns sabores de polpa as duas marcas não atenderam os valores padrões. Entre as polpas o único sabor que apresentou os padrões exigidos foi a polpa de caju em ambas as marcas, e a que apresentou resultado de pior qualidade diante dos padrões foi a polpa de maracujá principalmente da marca 1. Dessa forma constata-se que há grandes variações entre as marcas, e entre alguns parâmetros, o que compromete a qualidade das polpas, prejudicando assim o consumidor.</p><p align="center"><strong><em>Physicochemical parameters of fruit pulps produced in Petrolina – PE</em></strong></p><p><strong>Abstract</strong><strong>: </strong>This study aimed to evaluate the physicochemical parameters of fruit pulps produced and marketed in the city of Petrolina-PE, with reference to the Instruction Nº 1 of 7 January 2000 of the Ministry of Agriculture, which defines the physical and chemical characteristics setting minimum and maximum limits specific to each fruit pulp. We evaluated two brands (1 and 2) of pineapple, cocoa, cashew, soursop, passion and umbu fruit pulp, analyzed for pH, total soluble solids (TSS), total titratable acidity (TTA), ascorbic acid, TSS / TTA and total solids parameters. Results show that the brand 2 showed superior in most evaluated parameters when compared to the brand 1. However, for some pulp flavors of both brands did not reached the standards values. Among the pulps, the only flavor that presented the required standards was the cashew pulp in both brands, and presented the results of lower quality on the standards was the passion fruit pulp mainly brand 1. Thus, it appears that there are great variations between brands and between some parameters, which compromises the quality of the pulp, thus impairing the consumer.</p>

<p>O processamento de polpa e a fabricação de geleias são produtos de interesse para a região nordeste do Brasil. A baixa precipitação e os altos índices de luminosidade anuais, associado ao desenvolvimento da irrigação localizada na região, atraíram grandes empresas nacionais e internacionais para a produção de variados tipos de frutos, incluindo a acerola e o melão. O objetivo do presente trabalho foi avaliar as características físico-químicas de geleia simples e mista (50% de melão e 50% de acerola) de melão e acerola, por ocasião do preparo e após o armazenamento por 30 dias. Utilizou-se o delineamento inteiramente casualizado. O tempo de armazenamento aumentou o teor de sólidos solúveis (SS) e o pH, mas reduziu a acidez titulável e o teor de ácido ascórbico das geleias. A geleia de melão apresentou o maior teor de SS após o armazenamento. E a geleia de acerola obteve valores superiores de pH, acidez titulável e vitamina C, nas duas épocas de análise. Já a geleia mista apresentou pH igual à geleia de melão, mas quanto às demais características situou-se entre às geleias simples.</p><p align="center"><strong><em>Physical and chemical characteristics of acerola and melon jellies during storage</em></strong></p><p><strong>Abstract: </strong>The pulp processing and the manufacture of jellies are products of interest to the northeastern region of Brazil.

The guava (Psidium guajava L.) is a fruit plant that is widely distributed in Brazil. In the state of Mato Grosso, the culture adapted well in an irrigated system, however, there are still few studies related to the quality of the fruits produced in the state. In this way the objective of this work was to evaluate the physical and chemical characteristics of guava fruits cultivated in the region of Tangará da Serra - MT and establish the correlation between these characteristics. A randomized complete block design with three cultivars (Rica, Ogawa and Paluma) was used, four replications with six plants, where the following characteristics were evaluated: fresh mass, length, diameter, length / diameter ratio, pulp percentage, Total soluble solids, titratable total acidity, pH and ratio. The fruits of the cultivars Paluma, Rica and Ogawa cultivated in Tangará da Serra-MT have quality both for the in natura market and for the industry, in addition, a correlation of the physical and chemical characteristics of the guava fruits was observed, allowing the use Of simpler feature evaluations to aid the selection process.

Vineyards of ‘Niagara Rosada’ have shown great productive potential. However, the grape production has been affected by factors related to climate adversities. Thus, this study aimed to evaluate the effect of plastic cover and bagging of bunches of ‘Niagara Rosada’, in Almirante Tamandaré, PR, Brazil. Plastic cover used was of polyethylene with 250 µm of thickness and bagging of the bunches with white non-woven fabric bags. The treatments were: without plastic cover over the vineyard and without bagging of bunches (control); with plastic cover over the vineyard and without bagging of bunches; with plastic cover over the vineyard and with bagging of bunches; and without plastic cover over the vineyard and with bagging of bunches. To determine the quality of the grapes, we evaluated weight of the bunches and berry, width and length of the bunch, number of berries per bunch, total soluble solids (SS), titratable acidity (TA), pH, and SS/TA ratio. In both crop seasons, treatments with the protected plants or bunches were superior in all evaluated traits. The plastic cover and bagging of bunches delayed maturation and improved the physical and chemical characteristics of bunches and berries of ‘Niagara Rosada’.

The objective of this work was to evaluate the influence of different proportions of jambolan pulp, sugar and water on the physical and chemical characteristics to obtain information that allows the use of jambolan and, consequently, the evaluation of these fruits. Six jambolan nectar formulations were established through Simplex design. Ingredients significantly affected luminosity (32,14-34,24), apparent viscosity (7.8-73.8 cP), total soluble solids (8.87-26.43 °Brix), titratable acidity (0.55 -0.83g citric acid 100g-1) and the TSS / TA ratio (16.05-34.96) in jambolan nectars. Jambolan nectar with 55g 100g-1 of jambolan pulp, 15g 100g-1 of sugar and 30g 100g-1 of water has the highest desirability in relation to physical and physicochemical properties, 85.1% DPPH inhibition, 10526.12 μg TE mL-1 and 27014.25 μmol TE mL-1 by ABTS and ORAC method, respectively. It could be concluded that it is possible to produce jambolan nectar which can increase the possibilities of applying fruit as an ingredient in the food industry.
