RESUMEN

INTRODUCTION: The Brazilian psychiatric reform has revolutionized the way that mental health care is provided all over the country, introducing the Psychosocial Care Centers (CAPS) and encouraging care at liberty. The CAPS have been assigned many objectives, such as prevention of hospitalizations and intervention in crises or suicide. This paper aims to describe the correlation between the implementation of CAPS and the rates of psychiatric hospitalizations and suicides from 2008 to 2018. METHODS: This study has an ecological time series design and included residents of the city of Porto Alegre, RS, Brazil, who were hospitalized through the Sistema Único de Saúde (SUS). The data were obtained from official databases (DATASUS, CNES, and IBGE) and indicators were calculated (CAPS coverage, hospitalization rate, and suicide rate). Associations between the indicators were tested using Pearson's correlation coefficients. RESULTS: We found a negative correlation between provision of CAPS and psychiatric hospitalizations (r = -0.607 p = 0.048). CONCLUSION: These results support the hypothesis that there is a negative correlation between implementation of the CAPS and psychiatric hospitalizations. This reinforces the importance of implementing policies related to improving psychiatric reform.

RESUMEN

Ilex paraguariensis A. St. Hil. plants are used for the preparation of food and drinks which are widely consumed worldwide. During the harvest season of these plants, 2-5 ton hec-1 of agricultural residue is generated, which remains underutilized. Therefore, this study aimed to obtain an edible extract with high content of bioactive compounds and antimicrobial properties from the agricultural residue of I. paraguariensis for industrial use in food applications. The extraction conditions were optimized through a multivariate experimental design using ethanol:water. The extracted compounds were characterized by HPLC-ESY-QTOF-MS. In the optimal extraction conditions, 55 compounds were extracted, including 8 compounds that were not previously reported in I. paraguariensis. The method proved to be simple, fast, economical and environmentally friendly, with the use of green solvents. This optimization allowed for the extraction of 15.07 g of phenolic compounds per 100 g of residue. The extract showed high antioxidant activity and the capacity to inhibit Staphylococcus aureus. Results indicate that it is possible to obtain an edible extract with a high content of bioactive compounds, particularly phenolic compounds, from the I. paraguariensis residue, which has high prospects for the valorization of unexplored natural resources.

RESUMEN

The combination of oats such as water-soluble oat extract (SOE) and probiotic microorganisms can add nutritional value to the food and benefits to the consumer's health. The SOE contains soluble fiber, whose major soluble fraction is composed of ß-glucan contains soluble antioxidants such as ferulic acid, avenanthramides and other phenolic acids. The purpose of this study was to develop a fermented dairy beverage containing SOE, evaluating the viability of the probiotic culture, the fatty acid profile, phenolic compounds content and sensory characteristics during the storage. It was verified that Lactobacillus casei remained viable during the 21 days of storage (count above 7 Log CFU.mL-1) and that the addition of SOE does not affect the viability of probiotic bacteria. The levels of bioactive compounds soluble in aqueous medium, increased between the beginning of the experiment and the end, being influenced by the addition of SOE. Seven fatty acids were found in all formulations with a prevalence of C16:0 followed by C18:1. The addition of SOE in the formulation contributes to a significant increase in linoleic acid (C18:2n6). The sensory evaluation of the fermented oat dairy beverage with L. casei (BAC) was positive: the product was highly appreciated by consumers, with acceptance rate of 84.4%. The combination of SOE, with L. casei in the production of novel probiotic fermented dairy beverage, was technologically feasible, improving the functional properties of the product and offering health benefits to the consumer. More studies should be made to evaluate the composition and functional properties of SOE.

RESUMEN

A freeze-dried extract from the bark of mate branches (BMBE) containing high chlorogenic acids (CGA) content (30 g 100 g-1) was produced. Then, chia oil was mixed with 7.5% BMBE and sonicated for 0, 10, and 20 min. Chia oil with or without the addition of BMBE was hydrogelled and used to produce buffalo burgers with 50% reduction in animal fat. CGA levels and the nutritional, oxidative, and sensory properties of the burgers were analyzed. A reduction of ~30% fat and an increase above 60% PUFA/SFA ratio was observed for the reformulated raw and cooked burgers. In addition, the Omega-6/Omega-3 PUFA ratio of the burgers decreased from 20.8 (raw) and 31.9 (cooked) to values lower than 2. The addition of BMBE enriched the burgers with CGA, preventing an increase in lipid oxidation caused by chia oil. The addition of BMBE-enriched hydrogelled chia oil not subjected to sonication did not affect the sensory properties of the burgers.

RESUMEN

Ilex paraguariensis is a perennial plant used in the production of mate tea, "chimarrão" and "tererê," cosmetics, and other food products. Its leaves are harvested every 12 or 18 months. Approximately 2 to 5 tons of residue are generated per hectare during the harvest. The bioactive composition of this residue has not been characterized to date. Therefore, this paper presents for the first time, the simultaneous characterization of the bioactive compounds of the leaves, thin branches, and thick branches (residue) from I. paraguariensis grown under two cultivation systems: "full sun" and "shaded." The identification and quantification of the compounds was performed using high-performance liquid chromatography coupled to electrospray ionisation and quadrupole time-of-flight mass spectrometer (HPLC-ESI-QTOF-MS). Consequently, 35 compounds were identified. The average dry weight of phenolic compounds in the residue was 4.1 g/100 g, whereas that in the bark of the residue was 12.9 g/100 g, which was similar to the content found in leaves. The same compounds were identified in the two cultivation systems but with a difference in their contents. While the "full sun" cultivation had a higher content of phenolic acids, the "shaded" cultivation had a higher content of flavonoids and saponins. It was found that the I. paraguariensis residue, particularly the bark, is rich in bioactive compounds, such as quinic, 3-caffeoylquinic, 5-cafefoylquinic, 3,5-dicaffeoylquinic, and 4,5-dicaffeoylquinic acids as well as rutin, and their contents vary according to the cultivation system. Therefore, this residue is an underutilized natural resource with a potential for industrial applications. PRACTICAL APPLICATION: Yerba mate producers will be able to choose the best cultivation system ("full sun" or "shaded") to increase the content of bioactive compounds. New products may be developed with yerba mate residue due to its high concentration of compounds that are beneficial to the human health. New destinations may be applied to yerba mate residue from the harvest pruning, adding commercial value to this unexplored natural resource.

RESUMEN

BACKGROUND: Rice bran oil is unique among edible oils owing to its rich source of commercially and nutritionally important phytochemicals, such as oryzanol. γ-Oryzanol performs an important role in the stability of rice bran oil. The crude rice bran oil obtained by solvent extraction is subjected to either chemical or physical refining to meet the specifications of edible-grade vegetable oil. These refining processes can cause the compounds present in rice bran oil to degrade. The aim of this study was to evaluate the stability of γ-oryzanol present in chemically and physically refined rice bran oils, when submitted to temperatures of 100, 140, and 180 °C for a period of 1368 h. RESULTS: The chemically refined rice bran oil presented a lower γ-oryzanol content than the physically refined rice bran oil at all heating temperatures. The losses of γ-oryzanol at 100 °C, 140 °C, and 180 °C at the end of the heating periods for the chemically refined oil were 53.47%, 58.48%, and 97.05% respectively, and for the physically refined oil the losses were 38.11%, 53.58%, and 91.11% respectively. CONCLUSION: Based on the results of the time to reduce the oryzanol concentration by 50% and 100%, it is observed that the oil of rice meal refined physically presents greater stability, in the different temperatures studied and over time, than the oil of rice meal refined chemically. Thus, for situations where the oil needs to be subjected to prolonged heating, a temperature of 100 °C is indicated. In this condition, the physically refined oil is better for maintaining a higher concentration of γ-oryzanol. © 2021 Society of Chemical Industry.

RESUMEN

Due to the appreciable amounts of bioactive compounds in olive leaves and the effect of abiotic stresses on their synthesis, this study evaluated the metabolic profile of leaves of olive cultivars (Arbequina, Manzanilla and Picual) collected in four periods of the year (autumn, winter, spring and summer). The determination of the profile of bioactive compounds (phenolic compounds, flavonoids, tannins, carotenoids and chlorophylls) by spectrophotometry and the individual compounds by liquid chromatography coupled to mass spectrum, as well as antioxidant potential tests were performed. As results it was possible to observe that the leaves of the cultivar Manzanilla presented the highest levels of phenolic compounds and that the leaves collected in the summer presented a number of compounds much more relevant than the others. Thus, it was possible to conclude that the cultivar and the collection season significantly affect the bioactive content and the antioxidant potential of olive leaves.

RESUMEN

It is important to determine the chemical composition of fruits in order to establish their potential health benefits for human nutrition and thus stimulate their cultivation and consumption. Therefore, the objective of this study was to determine the physical and chemical parameters, vitamin C content, phenolic compounds, flavonoids and carotenoids, fatty acid profile and antioxidant activity of fruits from different regions of Brazil. We observed that the different regions and fruits studied presented very distinct characteristics. For example, the cupuaçu pit is rich in unsaturated fatty acids, while the genipap and java plum presented high flavonoid content and the butia had a high concentration of carotenoids. Guava was the fruit with the highest antioxidant activity through the ABTS radical, while the yellow mombim presented the best response when the activity was determined by FRAP.


Es importante determinar la composición química de las frutas para establecer sus potenciales beneficios para la salud humana y, por lo tanto, estimular su cultivo y consumo. El objetivo de este estudio fue determinar parámetros físicos y químicos, el contenido de vitamina C, los compuestos fenólicos, los flavonoides y los carotenoides, el perfil de ácidos grasos y la actividad antioxidante de las frutas de diferentes regiones de Brasil. De los resultados obtenidos en este estudio se pudo observar que las diferentes regiones y frutas estudiadas presentaban características muy distintas, ya que la semilla de cupuaçu es rica en ácidos grasos insaturados, mientras que el genipapo y la ciruela java presentaron un alto contenido de flavonoides y el butia presentó alta concentración de carotenoides. La guayaba fue la fruta con la mayor actividad antioxidante determinada por el radical ABTS, mientras que el mombim amarillo presentó la mejor respuesta cuando la actividad fue determinada por FRAP

RESUMEN

The Brazil nut is an important commodity that grows in the Amazon rainforest and is notable for its high nutritional value. However, the effect that packaging has on product shelf-life is unclear. This study evaluated the microbiological and nutritional quality of unshelled Brazil nuts packed in (a) nylon and polypropylene under vacuum, and (b) in polyethylene terephthalate and polyethylene aluminized films. The nuts were stored for nine months under natural environmental conditions. The most probable number of total and thermotolerant coliforms and Escherichia coli, and counting of molds and yeast were determined in the unshelled nuts shortly after collection and every three months during storage. Moisture, lipids, ash, neutral detergent fiber, and acid detergent fiber contents were measured by the gravimetric method. Crude protein content was measured using the Kjeldahl method. Coliform levels were within legislated standards in both types of packaging. Mold and yeast growth increased with time in both types of packaging (0.1x10¹ to 9.5x10³ colony forming units g-1), but only nuts packaged in aluminum film showed a significant increase after six months of storage. After nine months of storage, both types of packaged nuts had good nutritional quality. Aluminized packaging resulted in better conservation of the lipid fraction and lower permeability to water vapor, however, vacuum packaging was more effective in controlling fungal growth, possibly due to the lack of oxygen.


As castanhas-do-brasil são um importante produto da floresta amazônica e destacam-se pelo seu alto valor nutricional. Contudo, os efeitos da embalagem sobre a vida de prateleira das castanhas não estão completamente esclarecidos. Sendo assim, neste estudo, avaliou-se a qualidade microbiológica e nutricional de castanhas-do-brasil descascadas, embaladas em (a) nylon mais polipropileno a vácuo e (b) filmes aluminizados de polietileno tereftalato (PET) e polietileno (PE). As castanhas foram armazenadas por um período de nove meses, sob condições ambientais naturais. Logo após a coleta, e a cada três meses, foram determinados nas castanhas o número mais provável de coliformes totais, coliformes termotolerantes e Escherichia coli, e contagem total de bolores e leveduras. Também foram medidos os teores de umidade, lipídeos, cinzas, fibra em detergente neutro e fibra em detergente ácido por métodos gravimétricos, e os teores de proteína bruta por meio do método de Kjeldahl. Os níveis de coliformes termotolerantes estiveram dentro dos padrões da legislação nos dois tipos de embalagem. A incidência de bolores e leveduras aumentou ao longo do tempo nas duas embalagens (de 0,1x10¹ a 9,5x10³ unidades formadoras de colônia; UFC g-1), porém somente a embalagem aluminizada apresentou aumento significativo após seis meses de armazenamento. Após nove meses, as castanhas nas duas embalagens apresentaram boa qualidade nutricional, porém a embalagem aluminizada apresentou melhor conservação da fração lipídica e menor permeabilidade a vapores de água. Contudo, a embalagem a vácuo foi mais eficiente no controle do crescimento de fungos, possivelmente devido à ausência de oxigênio.

RESUMEN

Research has indicated the antifungal activity of ethanol extracts from propolis (EEP) on fungi of the genera Phakopsora, Colletotrichum, and Cercospora. Here, chemical compositions and antioxidant activity of three EEP (propolis from Scaptotrigona polysticta stingless bee and two types produced by Apis mellifera - red and brown) were evaluated and their action against Aspergillus flavus was investigated. Ash, dry extract, total phenolic and total flavonoid contents were determined. Phenolic composition was evaluated by high performance liquid chromatography, with using the following reference substances: gallic acid, caffeic acid, -coumaric acid, ferulic acid, quercetin, kaempferol, and apigenin. Tests on mycelial growth, sporulation, and germination of spores were performed to assess the biological activity of the EEP on A. flavus. All EEP showed low dry extract content (<11%) with adequate amounts of ash (<5%). The red EEP (Apis mellifera) showed the highest contents of total phenolic and total flavonoid (5.38 and 2.77 g 100 g-1), while the highest recorded antioxidant activity was exhibited by brown EEP (92.9%). The EEP of S. polysticta presented higher levels of -coumaric acid (10.99 mg g-1), while red and brown extracts from A. mellifera stood out with the highest levels of quercetin (27.26 mg g-1) and gallic acid (5.88 mg g-1), respectively. No extract was effective in inhibiting mycelial growth and sporulation of A. flavus, but red EEP inhibited spore germination. On the basis of these results, it is suggested that the inhibitory effect of red EEP on spore germination may be associated with increased levels of flavonoids found in it as compared with the other extracts investigated here.


Outros estudos apontaram a ação antifúngica dos extratos etanólicos de própolis (EEP) sobre fungos do gênero Phakopsora, Colletotrichum e Cercospora. Neste estudo, avaliou-se a composição química e a atividade antioxidante de três EEP (própolis produzido pela abelha sem ferrão Scaptotrigona polysticta e dois tipos de própolis produzida pela Apis melífera: marrom e vermelha) e sua ação contra o Aspergillus flavus. Foram determinados os teores de cinzas, extrato seco, fenólicos e flavonoides totais nos EEP. A composição fenólica foi determinada por cromatografia líquida de alta eficiência, empregando-se as seguintes substâncias de referência: ácido gálico, ácido p-cumárico, ácido ferrúlico, quercitina, kaempferol e apigenina. Para avaliar a atividade biológica dos EEP sobre A. flavus foram realizados os testes de crescimento micelial, esporulação e germinação de esporos. Todos os EEP apresentaram baixos teores de extrato seco (< 11%), porém quantidades de cinzas adequadas (< 5%). O EEP vermelha apresentou os maiores teores de fenólicos e flavonoides totais (5,38 e 2,77 g 100g-1), enquanto que a maior atividade antioxidante registrada foi do EEP marrom (92,9%). O EEP de S. polysticta apresentou maiores teores de ácido p-cumárico (10,99 mg g-1), enquanto que os de A. mellifera, vermelha e marrom, destacaram-se com os maiores níveis de quercetina (27,26 mg g-1) e de ácido gálico (5,88 mg g-1), respectivamente. Nenhum extrato foi eficaz na inibição do crescimento micelial e esporulação de A. flavus, porém observou-se inibição na germinação de esporos pelo EEP vermelha. Sugere-se que o efeito inibitório na germinação de esporos pode estar relacionado com os maiores níveis de flavonoides encontrados na própolis vermelha, quando comparado com os outros extratos investigados.

RESUMEN

Devido a poucos relatos da qualidade das castanhas-do-brasil oriundas do estado de Mato Grosso avaliaram-se as condições microbiológicas e nutricionais de amêndoas coletadas e beneficiadas, com e sem casca, por produtores de Itaúba/MT. Foram adquiridas 18 amostras em 3 locais distintos (6 amostras por local - 3 com casca e 3 descascadas). Foi investigada a qualidade microbiológica (coliformes totais, termotolerantes, Escherichia coli e bolores e leveduras) e nutricional (peso de 100 amêndoas, umidade, lipídios, proteína bruta e minerais totais). Os níveis de coliformes termotolerantes apresentaram-se abaixo do limite de tolerância preconizado pela legislação brasileira, contudo foi encontrada alta contaminação por bolores e leveduras, sendo as amêndoas sem cascas as mais contaminadas (627,27UFC.g-1). Observaram- se teores apreciáveis de lipídeos (63,25g.100g-1), proteína bruta (15,44g.100g-1) e minerais totais (2,69g.100g-1), porém elevados níveis de umidade (5,55g.100g-1), que podem estar relacionados com a alta contaminação fúngica encontrada. O descascamento influenciou na qualidade nutricional do produto, pois foram observadas diferenças significativas nas castanhas com e sem casca para os teores de lipídios, proteína bruta e cinzas entre os locais de amostragem e as formas de comercialização (teste Tukey p≤0,05).
