Full textA propagação sexuada continua sendo o principal método empregado na produção de mudas para a jabuticabeira (Plinia spp.), o que resulta no longo período de juvenilidade apresentado pelas plantas obtidas, com início de produção podendo ocorrer em até 14 anos. Para essas espécies ainda não foram estabelecidos métodos eficientes de propagação assexuada que permitam a produção em larga escala para formação de pomares comerciais com entrada em produção em poucos anos após o plantio. Assim, objetivou-se com este trabalho avaliar o comportamento de miniestacas semilenhosas e herbáceas de jabuticabeira tratadas com AIB, em relação à indução e formação de raízes adventícias. Foi utilizado o delineamento experimental inteiramente casualizado (DIC) para os dois experimentos com quatro repetições e sete miniestacas por parcela para os dois experimentos. Para o experimento 1 utilizou-se o esquema fatorial 2 x 2, sendo dois tipos de folhas nas miniestacas (par de folhas com limbo intacto e par de folhas com limbo reduzido à metade) e duas concentrações do AIB (0 e 1000 mg L-1). Para o experimento 2 utilizou-se o esquema fatorial 2 x 5, sendo dois tempos de imersão das miniestacas no AIB (30 e 60 segundos) e cinco concentrações do AIB (0; 50; 100; 200 e 400 mg L-1). As características avaliadas foram a porcentagem de miniestacas vivas, com calos, enraizadas, com folhas, número de raízes e comprimento da maior raiz. No experimento 2 também foi avaliado a porcentagem de miniestacas com brotação e comprimento médio da brotação. Os dados foram submetidos à análise de variância e análise de regressão para o tratamento quantitativo, ao nível de 5% de probabilidade, utilizando-se do software R. A escolha da equação de regressão baseou-se na significância dos coeficientes e no maior valor do coeficiente de determinação (R2). Conclui-se que a permanência do limbo foliar intacto nas miniestacas é essencial para o enraizamento e maior formação de calos; a aplicação de AIB é desnecessária para enraizamento de miniestacas herbáceas de jabuticabeira; e o emprego de miniestacas herbáceas obtidas de cepas se mostra viável para a multiplicação comercial de jabuticabeira.
The sexual propagation remains the main method used in the production of seedlings for jabuticaba tree (Plinia spp.) Which results in long juvenility presented by plants obtained with early production may occur in up to 14 years. For these species have not yet been established efficient methods of asexual propagation to enable the large-scale production for formation of citrus groves with entry into production in a few years after planting. Thus, the aim of this work was to evaluate the behavior of softwood and herbaceous cuttings of jabuticaba tree treated with IBA, for induction and formation of adventitious roots. It was used a completely randomized experimental design (CRD) for the two experiments with four replicates and seven cuttings per plot for the two experiments. For the experiment 1 used the factorial 2 x 2, two types of leaves on cuttings (leaf pair with intact limb and pair of leaves with reduced blade in half) and two IBA concentrations (0 and 1000 mg L 1). For experiment 2 used the factorial 2 x 5, two immersion times of the shoots in IBA (30 and 60 seconds) and five concentrations of IBA (0, 50, 100, 200 and 400 mg L-1). The characteristics evaluated were the percentage of live cuttings, calluses, rooted with leaves, root number and length of roots. In experiment 2 was also evaluated the percentage of cuttings with budding and average length of sprouting. Data were subjected to analysis of variance and regression analysis for the quantitative treatment, at 5% probability, using the software R. The choice of regression equation was based on the significance of the coefficients and the higher value of coefficient of determination (R2). It is concluded that the permanence of the intact leaf blade in cuttings is essential for rooting and higher callus formation; the AIB application is unnecessary for rooting herbaceous cuttings jabuticaba tree; and the use of herbaceous cuttings obtained from strains shown feasible for commercial multiplication jabuticaba tree.

Os compostos bioativos estão presentes em diversos frutos tais como a amora (Rubus sp.), mirtilo (Vaccinium sp.) e na casca de jabuticaba (Plinia jaboticaba). Levando-se em consideração essas frutas e seus altos conteúdos de compostos fenólicos, a indústria de alimentos deve possuir metodologias padronizadas que possibilitem identificar rapidamente sua capacidade antioxidante e teores desses compostos, que sejam eficientes e de baixo custo. Esta pesquisa tem por objetivo a obtenção de modelos matemáticos para a predição da capacidade antioxidante e dos teores de antocianinas e compostos fenólicos totais, dos extratos bruto e purificados, das frutas amora e mirtilo e da casca de jabuticaba por meio de parâmetros colorimétricos. Inicialmente, obteve-se o extrato fenólico bruto de amora e mirtilo e de casca da jabuticaba e, posteriormente, os extratos brutos foram purificados, resultando em outros dois extratos para cada fruta (fenólico e antociânico). Os extratos foram caracterizados por meio de medidas colorimétricas (L*, a*, b*, C* e h*), quantificação de antocianinas totais, pelos métodos pH único e pH diferencial, compostos fenólicos totais, e, capacidade antioxidante, pelos métodos ABTS, DPPH e FRAP. A correlação dos parâmetros colorimétricos, com as demais análises para todos os extratos, foi realizada pelo método de Pearson. A obtenção do modelo matemático para predizer os teores de antocianinas e compostos fenólicos, e, da capacidade antioxidante, foi realizada pelo método Stepwise. O extrato fenólico bruto apresentou coloração mais clara, tons mais avermelhados e amarelos quando comparado aos extratos purificados. O extrato de mirtilo foi o que apresentou maior teor de antocianinas totais, para os dois métodos empregados. Com relação à capacidade antioxidante, tanto para o extrato bruto, quanto para o extrato fenólico, a casca de jabuticaba foi o que apresentou valor mais elevado. Já para o extrato antociânico, os valores encontrados para a capacidade antioxidante, das três frutas, não diferiram significativamente (p > 0,05). Os parâmetros L*, a*, b*, C* e h* apresentaram correlação significativa, ao nível de 5% de probabilidade com os resultados obtidos para as análises de interesse, para o extrato bruto. Para o extrato fenólico, houve correlação para conteúdo de antocianinas totais com as coordenadas colorimétricas, e, para o extrato antociânico, houve correlação entre o parâmetro hue e o conteúdo de antocianinas totais e fenólicos totais. As correlações entre os parâmetros de cor e o conteúdo de antocianinas foram, em todos os casos, negativas, demonstrando que, à medida que o conteúdo de antocianinas aumenta, os parâmetros de cor diminuem. O extrato bruto obteve correlação entre os parâmetros de cor e todas as análises realizadas, o que resultou na obtenção dos modelos matemáticos para predição com elevado r 2 para as análises de conteúdo de antocianinas, de fenólicos e as três metodologias de capacidade antioxidante. Com o extrato fenólico foi possível a obtenção do modelo matemático para predizer o conteúdo de antocianinas utilizando os parâmetros colorimétricos. E para o extrato antociânico, obteve-se modelo para predizer o conteúdo de antocianinas, compostos fenólicos, DPPH e FRAP com as coordenadas de cor, com r 2 pouco significativo. Dessa forma, a predição dos teores de antocianinas e compostos fenólicos totais, e, capacidade antioxidante das três frutas, para o extrato fenólico bruto, utilizando os parâmetros colorimétricos, é viável e muito promissora para economia de custos e tempo.
Bioactive compounds are present in many fruits such as blackberry (Rubus sp.), blueberry (Vaccinium sp.) and jabuticaba skin (Plinia jaboticaba). Considering those fruits and their high content of bioactive compounds, the food industry should have standard methodologies that allow a fast identification of their antioxidant capacity, anthocyanins content and the amount of total phenolic compounds, and that would be efficient and have low cost. The objective of this research was to obtain mathematical models for the prediction of the antioxidant capacity and the anthocyanins and total phenolic contents of crude and purified extracts obtained from fruits of blackberry, blueberry and jabuticaba skins through the color parameters. Initially, the crude phenolic extracts were obtained from the blackberry, blueberry fruits and the jabuticaba skin, and then, they were purified, resulting in other two different extracts to each fruit (phenolic and anthocyanin extract). The extracts were characterized using the following analyses: Colorimetry (L*, a*, b*, C* e h*); Total anthocyanins (unique pH and differential pH); Total phenolic content; and antioxidant capacity, by three different methods, ABTS, DPPH and FRAP. In addition, a correlation was done between the color parameters and the other analyses, for the three different extracts, using Pearson method. Mathematical models to predict anthocyanins and phenolic compounds, and antioxidant capacity, were obtained using the Stepwise method. The crude phenolic extract presented, in general, lighter coloring, more reddish and yellowish tones when compared to the purified extracts. In addition, the blueberry extract was the one that presented greater total anthocyanins content, for the two methods used. The extracts obtained from jabuticaba skins, for both the crude extract and the phenolic extract, presented the highest values of antioxidant capacity. For the anthocyanin extract, the values found for the three fruits did not differ significantly (p> 0.05). The parameters L*, a*, b*, C* and h* showed significant correlation at 5% probability level with the results of the chemical analyses for the crude extract. However, for the phenolic extract, there was correlation only for the total anthocyanin content with the colorimetric parameters, and for the anthocyanin extract there was correlation between the hue parameter and the total anthocyanin and total phenolic content. The correlations between the color parameters and the anthocyanins content were negative in all cases showing that as the anthocyanins content increases, the color parameters decrease. The crude extract had correlation between the color parameters and all the analyses done resulting in a high r 2 prediction models for the analyses of anthocyanins content, phenolics and the three antioxidant capacity methodologies. Prediction models were obtained only for the anthocyanins content when the phenolic extract was used. For the anthocyanin extract, prediction models were obtained for the anthocyanin content, phenolic compounds, DPPH and FRAP, however with a lower r 2 . Thus, the prediction of the anthocyanin content, total phenolic compounds and the antioxidant capacity of the three fruits using colorimetric parameters is viable and very promising from the point of view of reducing cost and time.

Full textJabuticaba tree (Plinia sp.) is a native species that has been widely distributed in almost all regions of Brazil. Recently, different native fruits, including jabuticaba, have been a research aim in order to investigate the best benefit of its nutritional properties. In order to arouse new alternatives for better utilization of agro-industrial by-products with nutritional and functional properties, researchers are seeking to develop innovative and functional bioactive products. By this angle, this study aimed at evaluating whether different jabuticaba juice extraction processes applied to obtain peels interfered on its nutritional properties as well as on the subsequent dehydration in order to turn a nutrient-rich residue, agro-industrial benefitted, in a food product that can be attractive to the consumer, as well as easy to be handled, stored and transported. Thus, this study was divided into three phases: the first one was divided according to the acquisition of jabuticaba fruits, from two identified genotypes as: one genotype as acquired in Clevelândia farm (25°07'20" S and 52°19'15" W) and the other genotype from Verê farm (25°53'1'' S: 52° 55' 11'' W). The fruits underwent through extraction process by crushing and forced steam to obtain peels. Subsequently, peels were submitted to dehydration process in an oven with forced air circulation at 70 °C. Then, after being dehydrated, they were ground and sieved to an 80-mesh size to obtain powder. Analyses were carried out to evaluate the influence of these processes in bioactive compounds and their variations based on samples of fresh jabuticaba peels from each genotype, since they underwent through the extraction process and then dehydration. This research was based on physicochemical analyses of hydroalcoholic extracts of samples. Centesimal composition parameters were evaluated: total soluble solids (TSS), titratable acidity, pH, ash, fiber, protein and moisture content, bioactive compounds (phenols, flavonoids and anthocyanins) and antioxidant activity (DPPH, ABTS and FRAP). The way jabuticaba peel was extracted (fresh or dried - powder) did not influence the obtained physicochemical results, or antioxidant activities measured by ABTS and FRAP. Jabuticaba peels of both studied genotypes, extracted by crushing, showed the best contents concerning flavonoids, phenolic compounds and antioxidant activity by DPPH method. Jabuticaba peels of Clevelândia genotype showed the highest antioxidant content, flavonoids, phenolic, ABTS and FRAP. In the second moment of this trial, there was some effect of storage in anthocyanin content, antioxidant activity according to three different methods (DPPH, FRAP and ABTS), flavonoids, phenolic and physicochemical characteristics (moisture content, total acidity, pH, ashes, protein and fiber) of such waste powder (to obtain jabuticaba peel powder from both genotypes, extracted by steam and crushing). They also were vacuum packed and stored for 135 days. It was observed that the extraction by crushing showed the best results for DPPH activity according to the storage time and jabuticaba peel from Clevelândia genotype showed the highest antioxidant activity when compared to Verê genotype at the start time and over 135 storage days. Likewise this time has not changed, parameters as acidity and total protein content were obtained in both genotypes and their different extraction processes of jabuticaba powder peel. For the third phase, two evaluated waste samples were selected in phases I and II, which powder peel of Clevelândia genotype was extracted by forced-steam process (GCLV) while powder peel of Verê genotype was extracted by crushing (GVRE). Then, microbiological analyses were carried out (coliforms at 45 °C g-1, Salmonella spp. 25g-1 and yeasts and molds) with natural yogurt and selected powder peels of jabuticaba. Subsequently, four formulations were prepared and two of them were for each genotype: 3.6% GCLV and 1.8% GCLV while two ratios were for (3.6% / 1.8%) GVRE samples. The formulations were submitted to sensorial analyses of acceptability, purchase intent, frequency and reason for the evaluated product consumption, with 100 untrained consumers. The quality of jabuticaba peel color (Verê/Clevelândia genotypes) in powder was also evaluated after extraction xi (steam/crushing), and a*, b*, L*, C*, H* and Δab* color coordinates were analyzed. The dehydrated product and yogurt showed a low counting for filamentous fungi, yeasts, thermotolerant coliforms and absence of Salmonella spp., which indicates some good processing conditions. The addition of jabuticaba peel powder in yogurt resulted in good acceptance for samples such as 1.8g GCLV; 3.6g GCLV and 1.8g GVRE, whose answers varied from: “I liked moderately” and I liked very much”. These samples received results of good intention to buy samples such as 1.8g GCLV, 3.6g GCLV and 1.8g GVRE. Concerning color, there was no effect on the quality of jabuticaba peel powder up to 135 storage days. Generally, the obtained peels by crushing showed the highest contents of flavonoids, phenolic compounds and antioxidant activity by DPPH method. Therefore, antioxidants of this product in yogurt is a promising alternative, since the results showed good rates for both genotypes and extraction treatments (steam/crushing). Wherefore, this process not only provides some proper disposal for waste but also uses important nutrients and natural dyes to add value to several kinds of foodstuff.
