Sugar apple, atemoya and soursop are tropical fruits very prized for their pleasant, aromatic and distinctive flavor. In this work, the fresh fruits pulps had high nutritional values, since they contain significant levels of carbohydrates. ), pH (3.41, 3.34 and 3.41) and soluble solids (63.00, 65.00 and 68.60 °Brix). The jams were subjected to Quantitative Descriptive Analysis. A total of 12 trained panelists evaluated the attributes flavor, consistency, appearance and overall acceptability of the jams on a 9-point hedonic scale. Based on sensory evaluation, jams presented a good overall acceptability and atemoya jam was the most preferred by the panelists.Index terms: Tropical fruits, nutritional value, annonaceae. RESUMOFruta do conde, atemóia e graviola são frutos tropicais muito apreciados por seu sabor agradável, aromático e marcante. Neste trabalho, constatou-se que as polpas de frutas frescas tiveram altos valores nutricionais, uma vez que estas continham níveis significativos de carboidratos. Os resultados para a análise da composição química das polpas de frutas frescas, obtidos para fruta do conde, atemóia e graviola foram respectivamente: umidade (79,65, 77,06 e 85,30 g.100 g ), pH (3,41, 3,34 e 3,41) e sólidos solúveis (63,00, 65,00 e 68,60 °Brix). As geleias foram submetidas à Análise Descritiva Quantitativa. Um total de 12 provadores treinados avaliaram os atributos sabor, consistência, aparência e aceitabilidade global das geleias em uma escala hedônica de 9 pontos. Baseado na avaliação sensorial, as geleias apresentaram uma boa aceitação global e a geleia de atemóia foi à preferida dos provadores. Termos para indexação:Frutos tropicais, valor nutricional, anonáceas.

Tetracyclines and sulfonamides are broad-spectrum antibacterial agents which have been used to treat bacterial infections for over half a century. The widespread use of tetracyclines and sulfonamides led to the emergence of resistance in a diverse group of bacteria. This resistance can be studied by searching for resistance genes present in the bacteria responsible for different resistance mechanisms. Salmonella is one of the leading bacteria causing foodborne diseases worldwide, and its resistance to tetracyclines and sulfonamides has been widely reported. The literature review searched the Virtual Health Library for articles with specific data in the studied samples: the resistance genes found, the primers used in PCR, and the thermocycler conditions. The results revealed that Salmonella presented high rates of resistance to tetracycline and sulfonamide, and the most frequent samples used to isolate Salmonella were poultry and pork. The tetracycline resistance genes most frequently detected from Salmonella spp. were tetA followed by tetB. The gene sul1 followed by sul2 were the most frequently sulfonamide resistance genes present in Salmonella. These genes are associated with plasmids, transposons, or both, and are often conjugative, highlighting the transference potential of these genes to other bacteria, environments, animals, and humans.

Fruits and vegetables are essential components of a human healthy diet and there are considerable evidences of the nutritional benefits associated with the regular consumption of fresh fruits and vegetables (Goodburn & Wallace, 2013; Maffei et al., 2013). Consequently, nowadays, there is a growing interest in healthy diets, which increased consumption of vegetables and caused an expansion of the market for minimally processed vegetables. These products meet the needs of their consumers because of changes in the human lifestyle and its tendency to convenience and spending less time on preparing food (Gurler et al., 2015; Santos et al., 2012). Minimally processed vegetables can be obtained from the fresh products through selection, washing, peeling, cutting or slicing, sanitization, rinsing, drying and packaging (Gurler et al., 2015; Onternational Fresh-cut Produce Association, 2015; Tresseler et al., 2009). These products are defined as any fresh vegetable or combinations of them that has been physically altered from its original form, but remains in a fresh state, in order to preserve its nutritional and sensory properties (

Sapote (Quararibea cordata Vischer), also known as a chupa-chupa, is originated from the Brazilian, Peruvian and Colombian Amazon. The pulp of the ripe fruit is edible, fibrous, of intense orange color, sweet flavor and aromatic. Since the fruit is known in the Amazon only in its domesticated state, this work becomes necessary. With the aim of meeting the demand for new products in domestic and international markets, sapota pulp jelly has been developed. The jelly was assessed for moisture, ash, lipids, proteins, carbohydrates, dietary fiber, pectin, pH, total acidity, solids soluble, sugars, organic acids, carotenoids, phenolic compounds and antioxidant capacity. The final product met the standards required by Brazilian law, and 32.68% moisture and 61.06% °Brix. Also, in accordance with the laws attributed to this product, jelly sapota pulp can be considered a food rich in fiber, as presented content above 5%. The jelly, showed content of total phenolics compounds (102 mg GAE. 100 -1) in relation to fresh fruit (21 mg GAE.100 g -1). There was the identification in the antioxidant capacity (9.05% scavering of DPPH radical), giving the final product antioxidant properties. Also were analyzed the microbiological characteristics of the product which was not observed the presence of thermotolerants coliforms, yeast and molds. The sapota can be considered effective raw materials in the preparation of jam and this had an antioxidant activity and source of fiber.Index terms: Fiber, amazonic fruits, DPPH radical. RESUMOA sapota (Quararibea cordata Vischer), também conhecida como chupa-chupa, é originária da Amazônia Brasileira, Peruana e Colombiana A polpa do fruto maduro é comestível, fibrosa, de cor alaranjada intensa, sabor doce e aromática. Por ser conhecida na Amazônia somente no seu estado domesticado, torna-se necessário este trabalho Assim, visando a atender a demanda por novos produtos no mercado nacional e internacional, foi desenvolvida a geleia da polpa de sapota. A geleia foi avaliada quanto aos teores de umidade, cinzas, lipídeos, proteínas, carboidratos, fibras alimentares, pectina, pH, acidez total, açúcares, ácidos orgânicos, carotenóides, além de compostos fenólicos e capacidade antioxidante. O produto final atendeu às normas exigidas pela legislação brasileira, sendo 32.68% de umidade e 61.06 °Brix. Também, em conformidade com a normas legais atribuídas a esse produto, a geleia da polpa de sapota pode ser considerada um alimento rico em fibras, já que apresentou teor acima de 5%. A geleia apresentou maiores teores de compostos fenólicos totais (102 mg GAE.100 -1 ), em relação à fruta in natura (21 mg GAE.100 g -1 ). Houve a identificação na capacidade antioxidante na geleia de 9.05% de descoloração do radical DPPH, conferindo ao produto final propriedades antioxidantes. Foram analisadas ainda as características microbiológicas do produto onde não foi observada a presença de coliformes termotolerantes, bolores e leveduras. A sapota pode ser considerada matéria-prima efetiva no preparo de geleia...
