Neste trabalho, foram determinados experimentalmente o calor específico, a condutividade térmica, difusividade térmica e densidade de suco de lulo na faixa de conteúdo de água entre 0,55 e 0,90 (p/p em base úmida) e em temperaturas entre 4 e 78,6 °C. A condutividade térmica e o calor específico foram obtidos utilizando-se o mesmo equipamento - uma célula constituída de dois cilindros concêntricos - operando em estado estacionário e não estacionário, respectivamente. A difusividade térmica foi obtida através do método de Dickerson e a densidade determinada por picnometria. Tanto a temperatura como o conteúdo de água apresentaram grande influência nos dados experimentais das propriedades termofísicas do suco de lulo. Os resultados obtidos foram utilizados na obtenção de modelos matemáticos para predizer estas propriedades em função da concentração e temperatura.

Um equino macho, raça Manga Larga, de 20 dias de idade, pesando 55 kg foi atendido no Hospital Veterinário “Luiz Quintiliano de Oliveira” com histórico de queda no dia anterior, apresentando impotência funcional e desvio do eixo ósseo do membro pélvico esquerdo (MPE). Ao exame radiográfico, constatou-se uma fratura classificada como Salter- Harris tipo II, na região distal da tíbia esquerda, com indicação para osteossíntese. Ao exame físico geral, observou-se frequência cardíaca (FC) de 82 batimentos.min-1, frequência respiratória (f) de 60 movimentos.min-1, mucosas róseas, tempo de preenchimento capilar de dois segundos, temperatura retal (ToC) de 38,5oC e hidratação adequada. Como medicação pré-anestésica, administrou-se xilazina (0,5 mg.kg-1) IV. A indução foi realizada por meio da administração de midazolam (0,1mg.kg-1) e cetamina (2mg.kg-1) IV. Seguiu-se a intubação orotraqueal com sonda n o 12 conectando-se a um circuito anestésico com reinalação parcial de gases, e a manutenção foi realizada com isofluorano em fluxo diluente de oxigênio a 100%, sob ventilação espontânea. Realizou-se a técnica de anestesia peridural com o paciente em decúbito lateral direito, introduzindo uma agulha 30x8 percutaneamente até atingir o espaço peridural entre as vértebras L6 e S1, onde se administrou lidocaína a 2% (2,2mg.kg-1) com vasoconstritor, perfazendo um volume de 6 mLs. Adicionalmente foi realizado o bloqueio perineural dos nervos tibial e fibular do membro acometido, com administração de 5 mLs de lidocaína a 2% com vasoconstritor em cada ponto. A administração de anestésicos locais pela via peridural na região L6 – S1 não é rotineiramente usada em equinos, uma vez que provoca ataxia ou perda do tônus muscular, aumentando os riscos relacionados à intervenção anestésica. No entanto, a recuperação do potro nesse relato de caso foi rápida e isenta de complicações, provalvelmente proporcionando anestesia multimodal e consequentemente menor depressão cardiovascular. A associação da anestesia peridural e bloqueio dos nervos tibial e fibular à anestesia geral, pode ser uma alternativa para intervenções cirúrgicas em membros pélvicos de potros, uma vez que demonstrou ser efetiva e de fácil execução.

The objective of this study was to characterize energetically beersmade withhoney. The tests of beer production weremade withninetreatments,threecombination of the originalextract concentrations (11, 13and 15 °Brix) and threepercentagesof honeyin the wort formulation(0, 20 and 40%).The experimentwas completely randomizedwith two replications, totaling eighteenplots.Themashingprocesswas performed byinfusion, with honey added in the boiling step. After clarified, the wort had its extract contents corrected with the addition of filtered water and was inoculated withlowfermentation yeast .The fermentation occurred at 10 ° C. The beer was manually bottled and stored in a freezer at 0 °C for 15 days, formaturation. The beers were chemically analyzed on proximate composition (moisture, protein, lipid, ash, and carbohydrate), alcohol content (% m / m) and then calculated the energy value. The results ofchemical analysis andenergetic valuesof the beerswere subjected to analysisof variance (F test) and the means werecompared byTukey testat 5% probability. The commonbeershad the lowestenergy value (31.05 to 31.95 kcal100g-1) in relation toextra(36.42 to 38.42 kcal100g-1) and strong(38.20 to 40.17 kcal100g-1) beers. Theincrease in the original extractin beerraises theircaloric values. The presenceof honeyin the formulationincreasedthe energetic valuesincommon andextrabeersand decreasedin strong.The levelsof alcohol andcarbohydratewere predominant in thebeer energetic values,beingpossible to observeadirect relation amongthese components ofbeer and theircaloric value.

Apple is a fruit that offers promising prospect for industrialization as it has favorable characteristics for this purpose and can obtain products with good acceptance. In Brazil, approximately 15% of the production is processed into juice, and a portion is exported. Among the fresh fruit and juice, apple adds US$ 30 million annually to the Brazilian foreign exchange earnings. The aim of this study was to characterize, using chemical analysis, concentrated juices, commercial apple juice, nectar, and soft drink. In addition, to compare them with their respective Quality and Identity Standards (PIQ) published by the Ministry of Agriculture, Livestock and Food Supply (MAPA) and Codex Alimentarius. Concentrated juices and commercial beverages were analyzed in triplicate for soluble solids content (Brix), pH, total acidity (AT), and ratio. In concentrated juices, the Total Sugar Reducer (ART) was also assessed. The results obtained in the laboratory were compared with the PIQ and Codex Alimentarius to verify compliance with applicable regulations. Seven concentrate juices, five juices, six nectars, and three apple-flavoured soft drinks were analyzed. The Brix of pulpy and clarified concentrated juices were, respectively, 71.16±1.29 and 40.40±0.57°Brix. In all concentrated juices, the Brix was in accordance with Codex Alimentarius. The Brix and AT in sweetened clarified juices were 11.50±0.14°Brix and 0.18±0.04g of malic acid/100g sample. In pulpy whole juices the values ​​were 11.20±0.70°Brix and 0.30±0.06g of malic acid/100g sample. The values of Brix and AT in apple-flavoured soft drinks were 11.03±0.93°Brix and 0.18±0.04g of malic acid/100ml sample. Commercial juices and soft drinks also presented °Brix and AT in accord with the PIQ established by MAPA. The apple nectars could not be compared with the standards because they are not published by MAPA or Codex Alimentarius. The definition of the PIQ is an important tool for quality control of beverages manufacture in Brazil. Therefore, it is recommended for the control agencies to define the parameters that are not established.

Mulberry (Morus nigra L.) is a fruit with a great potential for technological uses, which could be employed to manufacture of syrups, ice cream, candies, yoghurts, beverages, jam, etc. Only the leaf from mulberry trees is commercially used for silkworm feeding. This tree is cultivated on many agricultural environments such as small rural proprieties and settlements. Small farmers waste a great amount of their production for not knowing about mulberry technology. Thus, the objective of this work was to access extraction yield and physical-chemical properties of mulberry whole juice from ripe, green and a mixture of both by using press and depulper. Statistical analysis of results was carried by media and standard deviation calculations. 173 kg of mulberry were picked being 49.31% ripe and 50.68% green. Press delivered greater extraction yield of whole juice (80.50% to 81.60%) when compared to press (71.43% to 77.50%). Whole juice obtained from both equipments has shown the following values: soluble solids 7.45% - 12.11%, titrable acidity 0.45 – 1.23%, ratio 6.03 – 26.84, pH 3.69 – 4.35, total reducing sugar 4.05% – 9.96%, reducing sugar 3.95% - 9.15%, sucrose 0.00% - 0.04%, turbidity 221.25 NTU - >4,000 NTU. Whole juices obtained from both equipments has shown similar physical-chemical characteristics except turbidity. The authors concluded that press was the best extraction equipment due to its greater yield and whole juice quality regarding turbidity
