As farinhas são muito utilizadas no processamento de diversos produtos de panificação e o seu desempenho tecnológico depende de características funcionais previamente descritas. O objetivo deste trabalho foi avaliar as propriedades funcionais tecnológicas de farinhas comerciais de origem vegetal. Foram realizadas análises de índice de absorção de água, capacidade de absorção de óleo, solubilidade em água, capacidade de formação de espuma, estabilidade da espuma, capacidade emulsificante, estabilidade da emulsão e capacidade de formação de gel. A farinha da casca de maracujá apresentou o maior índice de absorção de água (4,85%). Todas as farinhas apresentaram valores satisfatórios para capacidade de absorção de óleo. Os maiores valores de solubilidade em água foram apresentados pelas farinhas de linhaça dourada, feijão branco, linhaça marrom, uva e maracujá. Apenas as farinhas comerciais de trigo integral, feijão branco, banana, trigo branca e soja apresentaram capacidade espumante e estabilidade da espuma durante 120 minutos. Exceto pelas farinhas de uva e trigo branca, as farinhas comerciais avaliadas demonstraram atividade emulsificante interessante para a indústria de alimentos. As farinhas de aveia A e B e trigo branca, apresentaram formação de gel já na menor concentração avaliada. As farinhas vegetais comerciais estudadas apresentaram características que permitem seu uso como ingrediente para diversas aplicações de interesse para a indústria de alimentos.

A aveia é uma gramínea, pertencente à família poaceae e ao gênero avena. Seu grão é amplamente utilizado para a fabricação de produtos de panificação.  O biscoito é um produto que apresenta grande interesse comercial e está em constante desenvolvimento. Com base nos estudos o objetivo no trabalho foi explorar o efeito da incorporação da farinha de aveia no processamento de biscoito tipo cookie, com relação às características físico-químicas e microbiológicas. Foi elaborado biscoito tipo cookie enriquecido com farinha de aveia, com diferentes concentrações de aveia (2%, 4%, 6%). Estes foram avaliados quanto às características físico-químicas (pH, Sólidos Solúveis Totais, vitamina C e umidade) e microbiológica (Coliformes Totais). A partir das análises físico-químicas realizadas nos biscoitos foi possível verificar que houve diferença significativa apenas nas amostras de vitamina C, umidade e no teor de sólidos solúveis totais ao nível de 5% de significância, entre os biscoitos tipo cookie de aveia.

The importance of segment of flowers and ornamental plants in agribusiness are growing. Researches that analyze the situation of different sector of this segment may contribute to establishing politics and actions to stimulate its development. In order to attend this purpose, the aim of this research was to analyze segments of the flower and ornamental plant production chain, focusing on producers and retailers. For that, two different surveys were applied, composed of direct and indirect questions. The application was performed online, using social media or in person, in the company location or in trend fairs. It was observed that the flower and ornamental plant production is mainly a familiar business. Another important issue is that the springtime consists of a new date for flower and ornamental plant commercialization. The number of retailers has been increasing, and this segment had some improvements as sales of different products and services. The flower and ornamental plant commercialization are still, in the majority, in physical location shops, besides of all the technologies available for online sales.

Third molar extraction is a common procedure frequently accompanied by moderate or severe pain, and involves sufficient numbers of patients to make studies relatively easy to perform. The aim of the present study was to determine the efficacy and safety of the therapeutic combination of 10 mg piroxicam, 1 mg dexamethasone, 35 mg orphenadrine citrate, and 2.5 mg cyanocobalamin (Rheumazin ® ) when compared with 20 mg piroxicam alone (Feldene ® ) in mandibular third molar surgery. Eighty patients scheduled for removal of the third molar were included in this randomized and double-blind study. They received (vo) Rheumazin or Feldene 30 min after tooth extraction and once daily for 4 consecutive days. Pain was determined by a visual analogue scale and by the need for escape analgesia (paracetamol). Facial swelling was evaluated with a measuring tape and adverse effects and patient satisfaction were recorded. There was no statistically significant difference in facial swelling between Rheumazin and Feldene (control group). Both drugs were equally effective in the control of pain, with Rheumazin displaying less adverse effects than Feldene. Therefore, Rheumazin appears to provide a better risk/ benefit ratio in the mandibular molar surgery. Since the side effects resulting from nonsteroidal anti-inflammatory drug administration are a severe limitation to the routine use of these drugs in clinical practice, our results suggest that Rheumazin can be a good choice for third molar removal treatment.

RESUMO:Neste trabalho foi realizada a caracterização fitoquímica e avaliada a atividade antibacteriana in vitro dos extratos de Ageratum conyzoides L. (mentrasto), Gossypium hirsutum (algodão), Phyllanthus tenellus (quebra pedra), e Polygonum hydropiperoides (erva de bicho) frente à Staphylococcus aureus e Escherichia coli. Para a avaliação da atividade antibacteriana foi utilizado o método de difusão em ágar. Os testes foram realizados com o extrato nas graduações alcoólicas de 0 a 100% (v/v), na proporção de 20% (m/v -massa/extrator). Os testes fitoquímicos constataram a presença de açucares redutores, compostos fenólicos, flavonoides, taninos, triterpenos, e esteróides nas quatro espécies. O crescimento das culturas de S. aureus foi inibido por todos os extratos, com exceção do extrato de Mentrasto. A maior atividade de inibição foi observada pelo extrato de quebra pedra. Entretanto, nenhum dos extratos foi capaz de inibir o crescimento das cepas de E. coli. Os resultados são promissores, visto que três das quatro plantas selecionadas demonstraram possuir substâncias antibacterianas, o que motiva estudos subsequentes para o isolamento e identificação dos princípios ativos responsáveis por essa atividade, com potencial de uso na indústria farmacêutica. Palavras-chave: Fitoterapia, Escherichia coli, Staphylococcus aureusABSTRACT: In vitro antibacterial activity of four plant species at different alcoholic contents. In this study, phytochemical characterization was conducted and the in vitro antibacterial activity of extracts of Ageratum conyzoides L. (whiteweed), Gossypium hirsutum (cotton), Phyllanthus tenellus (shatterstone) and Polygonum hydropiperoides (swamp smartweed) was evaluated against Staphylococcus aureus and Escherichia coli. To assess the antibacterial activity, the agar diffusion method was used. Tests were performed with the extract at alcoholic contents from 0 to 100% (v/v), at 20% proportion (m/v -mass/extractor). Phytochemical tests indicated the presence of reducing sugars, phenolic compounds, flavonoids, tannins, triterpenes and steroids in all four species. The growth of S. aureus cultures was inhibited by all extracts, except for whiteweed extract. The highest inhibitory activity was observed for shatterstone. However, none of the extracts was capable of inhibiting the growth of E. coli strains. Results are promising since three of the four selected plants showed to have antibacterial substances, which stimulates further studies for the isolation and the identification of active principles responsible for this activity, with potential to be used in the pharmaceutical industry.

Due to the importance of the flower and ornamental plants sector in Brazilian agribusiness, studies that analyze the situation of its different segments can help to understand and establish policies and actions that support and stimulate their development. The objective was to analyze the profile and behavior of consumers in the productive chain of flowers and ornamental plants. For this, a questionnaire with direct questions was prepared and directed to consumers of flowers and ornamental plants. The application was made personally with direct approaches in places of great movement and specialized technological fairs, and also online through social media, using Google platform. The results were analyzed by comparing qualitative variables using the Chi-Square test. It was identified that the profile of consumers is concentrated in women who live in large cities, consuming an average of R$ 100.00 to R$ 200.00 over a period of one year.

This study aimed to evaluate the anti-inflammatory and antinociceptive effects of hydroalcoholic extract of P.gonoacantha leaves (EPG). The toxic effect of the EPG was tested against A.salina in order to determine a secure dose for subsequent assays. The antinociception was evaluated using the acetic acid-induced writhing and hot plate tests in Wistar rats. The anti-inflammatory effect of EPG was evaluated by carrageenan-induced paw edema tests in rats. The bioassay with A.salina showed low toxicity of EPG (LC 50 =1,508mg/L). Oral administration of EPG (50, 100 and 150mg/kg) significantly decreased the number of acetic acid-induced writhes, around 61.3%, 71.8% and 64.9% respectively. However, EPG failed to prolong the latency time in the hot plate test, suggesting that EPG predominantly inhibits peripheral pain mechanisms. The oral administration of EPG at doses of 50 and 100mg/kg significantly inhibited paw edema at 3rd h after the injection of the phlogistic agent by 34.5% and 37.5%, respectively. These data suggest that EPG has both antinociceptive and anti-inflammatory activities, and these effects may be attributed to inhibition of COX-2 and prostaglandin release.
