Título: Effect of Maltodextrin Concentration and Inlet Air Temperature on Properties of Spray Dried Powder from Reverse Osmosis Concentrated Sweet Orange Juice
Fonte: Braz. arch. biol. technol;63:e20190538, 2020. tab, graf.
Idioma: en.
Resumo: Abstract Sweet orange juice is an important part of diet since it is nutritious beverage offering good taste and play significant part in a healthy diet. High hygroscopicity, thermo-plasticity and presence of low molecular weight components in sweet orange juice offer low glass transition temperature (Tg), likely to form soft particle with sticky surface leading to sticky powder during drying. Maltodextrins are amorphous drying aids that tend to inhibit sugar crystallization and form a high Tg product after drying. In this study, the effect of the different spray drying parameters on the quality of powder derived from control and concentrated juice at three inlet air temperatures 120, 130 and 140 °C and at three levels of juice total soluble solids (TSS): maltodextrin levels at 1:0.5; 1:1 and 1:1.5 were studied. The impact of inlet air temperature and maltodextrin concentration has significantly affected various properties of sweet orange powder. For control juice, process yields increased with increase in inlet air temperature and maltodextrin concentration. However, for reverse osmosis (RO) concentrate, process yield increased with increase in maltodextrin concentration and decreased with increase in inlet air temperature. For control juice, process yields obtained were in the range of 12.59-41.16% and in case of concentrated juice, the process yield obtained was in the range of 21.35-56.95% at different combinations of inlet air temperature and maltodextrin concentrations. Spray-dried powder was considered as "possible" and "fair" in terms of flowability and cohesiveness. Vitamin C retention was high at lower inlet air temperature with lower concentration of maltodextrin.

Resumo: Resumen Los estudios de la araneofauna en los agroecosistemas son cruciales para la implementación de las arañas como agentes potenciales de control biológico de plagas. En este trabajo se analiza la distribución del ensamble de arañas en los microhábitats (follaje, tronco y suelo) de los cultivos de Citrus sinensis, (Rutaceae) de la Provincia de Corrientes, Argentina. Los muestreos se realizaron mensualmente mediante cuatro técnicas de captura: agitación de follaje, tamizado de hojarasca, pitfall y captura manual. En total se obtuvieron 2 160 muestras y 7 194 ejemplares de arañas (2 462 en follaje, 983 en tallo y 3 749 en suelo) pertenecientes a 35 familias y 200 especies de Araneomorphae. Hubo diferencias significativas en la estructura de las comunidades de arañas de los tres microhábitats y entre los meses, según el análisis de similitud (ANOSIM). El follaje presentó mayor diversidad, seguido por el suelo y el tronco. Araneidae, Theridiidae y Salticidae predominaron en el follaje; las especies dominantes fueron: Jessica erythostoma y Cheiracantium inclusum, esta araña es una de las principales depredadoras de las larvas de Phyllocnistis citrella (Lepidoptera) que atacan las hojas de Citrus. En el tronco abundaron: Tetragnathidae, Hersiliidae y Theridiidae, destacándose Iviraiva pachyura, una especie especialista en dicho microhabitat; y Leucauge venusta la cual consideramos que es una especie oportunista, debido a que su abundancia se incrementa notablemente en sitios modificados por el hombre. En el suelo abundaron: Lycosidae, Linyphiidae y Coriniidae; Lycosa erythrognatha fue la especie dominante, seguida de Pardosa plumipedata. El índice de similitud Chao-Jaccard fue mayor entre el follaje y el tronco (J-C = 0.95), asimismo el ordenamiento Escalado Multidimencional no Métrico (NMDS) mostró una clara diferenciación de la composición de especies del suelo con respecto al follaje y al tronco. Además, en el suelo hubo mayor recambio temporal de especies y el método de seriación resultó significativo (z = 3.82, P = 0 .00) por lo tanto hubo una sucesión de especies durante el año de muestreo. Las especies en cada microhabitat probablemente evitan la competencia al utilizar distintas estrategias de caza y recursos ecológicos, además de patrones específicos de distribución temporal. Nuestros resultados sugieren que las modificaciones del ambiente, como en estos cultivos de C. sinensis, tienden a albergar varias poblaciones de arañas que se adaptaron a dicho cambio e interactúan de manera equilibrada en espacio y tiempo.(AU)

Abstract Arachnofauna studies from agroecosystems are crucial for implements spider as biological control agents. In this work we analyze the distribution of spider assemblages at three microhabitats (canopy, tree trunk and soil) in Citrus sinensis orchards (Rutaceae) in the Province of Corrientes, Argentina. Spiders were collected monthly using four sampling techniques: beating foliage, leaf litter sifting, pitfall traps and direct capture by hand. A total of 2 160 samples were examined and 7 194 spiders were collected (2 462 on the canopy, 983 on trunk and 3 749 on the floor) belonging to 34 families and 200 species/ morphospecies of Araneomorphae. There were significant differences among microhabitats and months in the structure of the spider communities, according to analysis of similarity (ANOSIM). The diversity was highest on the canopy, followed by soil and tree trunk. Araneidae, Salticidae and Anyphaenidae were the most abundant taxa in the canopy; the dominant species were Jessica erythostoma and Cheiracanthium inclusum, a predator of the leaf herbivore Phyllocnistis citrella (Lepidoptera) a pest of Citrus spp. The most abundant families on the tree trunk were Tetragnathidae, Hersiliidae and Theridiidae, Iviraiva pachyura was a species specialist in such microhabitat; and Leucauge venusta was an opportunistic species, because their abundance increaseds markedly in anthropic environments that modified by man. The most abundant families on the floor were Lycosidae, Linyphiidae and Coriniidae. In this habitat, Lycosa erythrognatha and Pardosa plumipedata were dominant species. The Chao-Jaccard similarity index was highest between the canopy and trunk (J-C = 0.95), likewise ordination by nonmetric multidimensional scaling (NMDS) revealed strong differentiation between assemblages of soil spiders and canopy and trunk spiders. Also, on the soil the temporary replacement of species was greater and the seriation method was significant (z = 3.82, P = 0.00) therefore there was a succession of species during the year. The different species in each microhabitat probably avoided competition by using different hunting strategies and different ecological resources, in addition to specific patterns of temporal distribution. Our results suggest that anthropic environments, such as in Citrus orchards, tend to harbor populations of spiders able to adapt to those environments and interact in a balanced way in space and time.(AU)

Título: Assessment of pectinase-producing fungi isolated from soil and the use of orange waste as a substrate for pectinase production
Fonte: Rev. ciênc. farm. básica apl;40, 01/01/2019. ilus, tab.
Idioma: en.
Resumo: Pectinases are important enzymes not only for their potential applications in different industries such animal feed, agricultural, textile, beverage, food processing, oil extraction, etc. Ten fungal species were isolated from the soil and screened for production of pectinase enzyme by using the pectin agar medium. Pectinolytic enzymes synthesis were attained at a temperature of 30 °C and activities were determined after a seven-days culture of Aspergillus sp. 391 and Aspergillus sp. 031, in a basic medium containing 2% citrus pectin and as the sole carbon source. The extract enzymatic showed an optimum activity for exo-polygalacturonase (PG) and pectin lyase (PNL) against galacturonic acid and pectin at pH 4.5 and 5.5, respectively. There were variations in PG and PNL enzymes levels produced in culture filtrates obtained of Aspergillus sp. 391 with addition of citrus waste (2.0 and 4.0 % w/v) to the medium. Maximum activity for PNL activity was observed in the medium containing 5% pectin or 4% citrus waste, as sole carbon source, after 7 days of growth. The results showed that the isolate Aspergillus sp. 391 is a promising for pectinolytic enzymes production at the industrial level.(AU)

Resumo: Objetivos: evaluar la composición química, propiedades fisicoquímicas del aceite esencial de la especie vegetal Citrus sinensis L, obtenidos mediante hidrodestilación e hidrodestilación asistida por la radiación con microondas, así mismo realizar una comparación entre los dos métodos de extracción utilizados. Método: los aceites esenciales se obtuvieron por hidrodestilación e hidrodestilación asistida por radiación con microondas, a partir del pericarpio de los frutos; se determinó densidad relativa a 20 °C, índice de refracción; solubilidad de los aceites esenciales en etanol 70 por ciento (v/v). La composición química se evaluó mediante cromatografía de gases/espectrómetro de masa. Resultados: los rendimientos oscilaron entre 0,51 y 0,42 por ciento, dependiendo del método de extracción utilizado. El aceite esencial extraído del Citrus sinensis L presentó como componente mayoritario el limoneno, independientemente de la metodología de extracción utilizada. Se obtuvo un mayor contenido de aceite esencial cuando se empleó la extracción mediante hidrodestilación asistida por microondas, en comparación con la hidrodestilación convencional. Conclusiones: el rendimiento del aceite esencial de Citrus sinensis L (Naranja) es dependiente del método de extracción utilizado para su obtención, se demuestra que la hidrodestilación asistida por microondas es un método rápido y eficiente en comparación con la hidrodestilación convencional(AU)

Objectives: to assess the chemical composition and physicochemical properties of essential oil of the plant species Citrus sinensis L, obtained by hydrodistillation and microwave radiation-assisted hydrodistillation, and to make a comparison between two extraction methods used. Methods: essential oils were extracted by distillation and microwave radiation-assisted hydrodistillation from the fruit pericarp; relative density at 20 °C, refractive index and the essential oils solubility in ethanol (70 percent v/v) were determined. The chemical composition was assessed using chromatography mass spectrometer/gas. Results: the yields ranged from 0,51 to 0,42 percent, depending on the extraction method used. The essential oil of Citrus sinensis L. by both methods had limonene as a major component. A higher content of essential oil was obtained when the microwave radiation-assisted method was used compared with the conventional hydrodistillation. Conclusions: the yield of the essential oil from Citrus sinensis L. (Orange) depends on method of extraction used; microwave-assisted hydrodistillation is faster and more efficient method than the conventional hydrodistillation(AU)

Resumo: ABSTRACT Objective We investigated the postprandial response of lipid markers to a high-fat meal (HFM) with two different beverages in apparently healthy normal-weight and overweight/obese women. Subjects and methods This crossover, randomized study enrolled 36 women, of whom 21 had normal weight (body mass index [BMI] 22 ± 1.8 kg/m2) and 15 had overweight/obesity (BMI 31 ± 3.7 kg/m2). In two different test days, the participants ingested a HFM (37% of energy as saturated fat) with 500 mL of water (HFM-W) or 500 mL of orange juice (HFM-OJ). Blood samples were collected at baseline (12-hour fasting), and at 2, 3, and 5 hours postprandial. The analysis included fasting and postprandial total cholesterol, HDL-c, LDL-c, triglycerides (TG), uric acid, and complement C3. Brazilian Clinical Trials Registry (ReBEC); Primary Identification Number: RBR-2h3wjn (www.ensaiosclinicos.gov.br). Results TG levels increased at 3 hours with HFM-OJ in normal-weight women (p = 0.01) and returned to normal levels at 5h. TG increased at 3 hours with HFM-W (p = 0.01) and HFM-OJ (p = 0.02), and remained high at 5 hours (p = 0.03) in overweight/obese women. Complement C3 remained unchanged, but showed different responses between meals (p = 0.01 for positive incremental area under the curve [piAUC] HFM-OJ vs. HFM-W, respectively). Conclusions In apparently healthy overweight/obese women compared with normal-weight ones, the concomitant intake of orange juice with a HFM prolonged postprandial lipemia but had no effect on postprandial complement C3 concentrations.

Resumo: Este estudo avaliou a capacidade antioxidante e os indicadores físico-químicos de néctares caseirosde laranja, manga e maracujá, mantidos sob refrigeração (5 ± 2 oC) por 24 horas. Os néctaresforam preparados em laboratório e mantidos sob refrigeração, simulando as condições domésticas.As análises foram realizadas após o preparo (T0) e durante o acondicionamento sob refrigeração(1 h, 4 h e 24 h). Os sólidos solúveis, pH e cor foram determinados respectivamente por refratometria,potenciometria e colorimetria. Carotenoides e ácido ascórbico foram analisados por cromatografialíquida de alta eficiência; a concentração de compostos fenólicos foi determinada utilizando-seo reagente de Folin Ciocalteau e a atividade antioxidante pelo teste do DPPH. Ácido ascórbico,β-caroteno e compostos fenólicos foram identificados em todos os néctares. Foram encontradosα-caroteno e β-criptoxantina no néctar de laranja e licopeno no néctar de manga. Durante 24 horasde refrigeração, os compostos analisados e a atividade antioxidante mantiveram-se estáveis. De formageral, os parâmetros físico-químicos também se mantiveram estáveis durante o período avaliado.Em conclusão, sob as condições utilizadas no presente estudo, os néctares não apresentaramalteração da capacidade antioxidante, podendo ser considerados fontes de carotenoides e vitamina C,mesmo se consumidos após 24 horas de preparo.

The objective of the study was to evaluate the antioxidant capacity and the physical-chemicalindicators of homemade nectars of orange, mango and passion fruit, kept under refrigeration(5 ± 2 °C) for 24 hours. The nectars were prepared in laboratory and kept under refrigerationsimulating the domestic conditions. The samples analyses were performed after their preparations(T0) and during the refrigerated storage (1 h, 4 h and 24 h). Soluble solids, pH and color weredetermined by refractometry, colorimetry and potentiometry, respectively. Carotenoids andascorbic acid were analyzed by high performance liquid chromatography, the concentrationof phenolic compounds were determined by using Folin Ciocalteau reagent, and the antioxidantactivity by the DPPH test. Ascorbic acid, β-carotene and phenolic compounds were identified inall of the analyzed nectars samples. The α-carotene and β-cryptoxanthin were found in orangenectar and the lycopene in mango nectar samples. During the refrigeration for 24 hours,the analyzed compounds and the antioxidant activity remained stable. In general, thephysical-chemicals parameters also remained stable during the storage for 24 hours. In conclusion,under the conditions used in this study, the nectars might be considered as antioxidant sources,even if consumed after being prepared 24 hours before.

Resumo: Background: Gene expression analysis via microarray is widely used in phytobacteria to validate differential gene expression associated with virulence or to compare biological profiles of wild type and mutant strains. Here, we employed DNA microarrays to study the early stages of the infection process (24, 72 and 120 h post-inoculation) of Xanthomonas citri subsp. citri (Xac) infecting Citrus sinensis to interrogate the expression profiles of hypothetical genes. Results: Under infective conditions, 446 genes were up- and 306 downregulated. Outstanding among genes upregulated during infection were those involved in synthesizing the Type 3 Secretion System and effectors, xanthan gum and quorum-sensing induction, and flagellum synthesis and regulation. Additionally, 161 hypothetical genes were up- and 100 were downregulated, 49 of which are known to have a significant biological role. To understand hypothetical gene co-regulation or -expression, nine expression profiles including 158 genes were identified during the three infection phases. Of these, 47 hypothetical genes were identified as having expression profiles associated with at least one connected to a gene associated with adaptation and virulence. Conclusions: Expression patterns of six differentially expressed genes were validated by quantitative reverse transcription polymerase chain reaction, thus demonstrating the effectiveness of this tool in global gene expression analysis in Xac.

Resumo: Background: Biotechnological processes are part of modern industry as well as stricter environmental requirements. The need to reduce production costs and pollution demands for alternatives that involve the integral use of agro-industrial waste to produce bioactive compounds. The citrus industry generates large amounts of wastes due to the destruction of the fruits by microorganisms and insects together with the large amounts of orange waste generated during the production of juice and for sale fresh. The aim of this study was used orange wastes rich in polyphenolic compounds can be used as source carbon of Aspergillus fumigatus MUM 1603 to generate high added value compounds, for example, ellagic acid and other molecules of polyphenolic origin through submerged fermentation system. Results: The orange peel waste had a high concentration of polyphenols, 28% being condensed, 27% ellagitannins, 25% flavonoids and 20% gallotannins. The major polyphenolic compounds were catechin, EA and quercetin. The conditions, using an experimental design of central compounds, that allow the production of the maximum concentration of EA (18.68 mg/g) were found to be: temperature 30°C, inoculum 2 × 107 (spores/g) and orange peel polyphenols 6.2 (g/L). Conclusion: The submerged fermentation process is an effective methodology for the biotransformation of molecules present in orange waste to obtain high value-added as ellagic acid that can be used as powerful antioxidants, antibacterial and other applications.

Resumo: Foi avaliada a atividade antimicrobiana do eugenol contra Alicyclobacillus hesperidum, Alicyclobacillus cycloheptanicus, Alicyclobacillus acidiphilus, Alicyclobacillus acidoterrestris e de Alicyclobacillus spp., isolados em indústrias de sucos de laranja de várias regiões do Estado de São Paulo. O teste de suscetibilidade para o eugenol foi realizado determinando-se a concentração inibitória mínima (CIM)pela técnica de microdiluição em placas de 96 cavidades. A CIM do eugenol variou de 66,65 a >1066,4μg/mL, evidenciando-se a atividade inibitória forte e moderada frente a todas as amostras testadas e a atividade bactericida. Este estudo demonstrou ser significativa a fonte de isolamento das linhagens de Alicyclobacillus spp. nas indústrias. Conclui-se que o eugenol possui eficaz atividade antimicrobiana contra Alicyclobacillus spp. e sugere-se o uso deste composto para prevenir a deterioração de bebidas acidificadas e para diminuir o custo do controle microbiológico mais especificamente em suco de laranja.
