Colorimetric change of assai (Euterpe oleracea Mart.) after preservation and thermal processing of the fruit.

Amazonian areas is far from the consumer center. Those characteristics promote a decline in visual quality of the fruit at the time of commercialization and consequently of the beverage processed. The aim of this study was to evaluate the influence of the assai fruit conservation and heat treatment, usually applied before its transformation into a pulp or beverage by artisan processing. Assai fruits were collected in 2013 in Mazagão, Brazil, packed in polypropylene bags, vacuum sealed and refrigerated (8-10°C) during four days. The treatments consisted of i.) fruits packed under vacuum (T1), ii.) fruits softening with potable water at 45°C for 20 minutes before bleaching (T2), ii.) fruits which have not been softened before bleaching (T3), iii.) fruits bleached at 80°C for 10 seconds (T4) (Rogez et al., 1996) and iv.) packaged fruit pulps prepared in the presence (T5) and iv). absence of vacuum (T6). The instrumental color of fruits and pulps was evaluated by colorimeter CR- 400 Konica Minolta. Fruit pulp preserved in vacuum (T5) showed the darkest luminosity (L*29.39), well as a more reddish color (a*8.51) and also more blue (b*-4.10). Considering ?E 12.55, there was a significant difference between vacuum packed fruit (T1) and without vacuum fruit pulps (T6). Otherwise, pulps from vacuum packed fruits (T5) and ones with absence of vacuum packed fruits (T6) also presented statistical difference (?E 7.80). The highest value C* was observed in vacuum packed pulps (T5) (9.45), which presented with a brighter and stronger color than the fruit pulp without vacuum (T6) (C*7.01). Regarding H°hue, the pulp from fruits without vacuum (T6) showed higher values (H°78.36) when compared to the pulp from fruits under vacuum (T5) (H°73.84). Compared to thermal processing, bleaching was not statistically influenced by purity of the color (C*) of softened fruit pulps (T2) (C*8.50) and fruit pulps that were not softening (T3) (C*8.00). The highest total color difference was observed in the bleached pulps that were previously softened (T4) (?E12.85). Assai fruits vacuum packed retain the best attributes of drink produced. Softening of the fruit before bleaching also influences the change in color of the drink, which may represent significant quality loss for the product and value for the merchant and consumers.UP371

Prevalência de anticorpos contra o vírus da hepatite B em população urbana do nordeste brasileiro

A sample of 1,288 inhabitants of Salvador, Bahia, Brazil, were submitted to the determination of anti-HBs using radioimmunoassay procedure, and analysed according to age, sex and income. Overall prevalence of anti-HBs was 11,8%. ranging from 6,7% among children aged less than three years old to 26,1% among those aged 30 years and older. Males presented prevalence of anti-HBs similar to female individuals, and those with a higher income showed frequencies of anti-HBs greater than those with a lower income level. The following conclusions were drawn: The high prevalence of anti-HBs observed among children suggests early contact with hepatitis B virus, possibly due to vertical transmission and intrafamiliar dissemination of the disease; the frequency of anti-HBs increases with age; the lower prevalence of anti-HBs among those with low income suggests that this group may present higher prevalence of carriers of the hepatitis B virus surface antigen.Um grupo de 1.288 indivíduos, residentes em Salvador, Bahia, Brasil, foi examinado para a determinação de anti-HBs, utilizando-se a técnica do radioimunoensaio. Os resultados foram analisados de acordo com a idade, o sexo e o nível de renda. Uma prevalência de anti-HBs de 11,8% foi observada, variando de 6,7% nas crianças com idade inferior a três anos, a 26,1% para aqueles com idade superior a 30 anos. A prevalência de anti-HBs foi similar em indivíduos do sexo masculino e feminino. Aqueles com nível de renda mais alto tiberam prevalência de anti-HBs maior que o grupo de renda baixa. Dos resultados conclui-se: a alta prevalência de anti-HBs em crianças sugere o contato precoce com o vírus da hepatite B, possivelmente relacionado com a transmissão vertical e a disseminação intraíamiliar do vírus; a freqüência de anti-HBs aumentou com a idade; a baixa prevalência de anti-HBs entre aqueles com baixo nível sócio-econômico sugere que neste grupo pode ser alta a prevalência de portadores do vírus B da hepatite

Invited review: Compost-bedded pack barns for dairy cows

Compost-bedded pack barns (CBP) are receiving increasing attention as a housing system for dairy cows that has potential to improve animal welfare. This article reviews current scientific knowledge about CBP with the aim of providing a comprehensive tool for producers and researchers using this housing system. In CBP, cows are provided with an open bedded pack area rather than the individual stalls and concrete alleys found in freestall systems. The bedded pack, a mixture of organic bedding and cattle excreta, is cultivated frequently (1–3 times per day) to incorporate fresh manure and air into the pack, thus promoting an aerobic composting process. To function well, CBP generally require a large area per cow. Optimal animal densities over the bedded area range from 7.4 to more than 15 m2/cow depending on several factors, including climate, bedding, pack management, and cow characteristics. Studies have indicated that CBP, compared with conventional systems such as freestall barns, have the potential to improve the welfare of dairy cows. In particular, the main reported benefits include improved comfort during resting, better foot and leg health, and more natural animal behavior. Research has also indicated that adequate udder health can be achieved in CBP. However, because the bedded pack has been shown to contain high bacterial concentrations, proper management is essential to maintain adequate cow cleanliness and reduce the risk of mastitis. Controlling pack moisture is consistently indicated as the most important issue with CBP. Especially under cold and humid weather conditions, large amounts of bedding may be necessary to keep the pack adequately dry and comfortable for the cows. Nevertheless, the improvements in cow health may offset the higher costs of bedding.</p

Efeito de indutores de resistência na incidência do mal do Panamá em banana maçã.

O mal do Panamá ou murcha de Fusarium, causado por Fusarium oxysporum Schlechtend.: Fr. f.sp. cubense (E.F. Smith) W.C. Snyder & Hansen, é uma das doenças mais importantes da bananeira (Musa spp.). Primeiramente relatado na Austrália, esta doença está presente em todas as regiões produtoras do mundo. Nas décadas de 1950 e 1960, o mal do Panamá dizimou a bananicultura da América Central e Caribe, então constituída unicamente da variedade Gros Michel (Daly & Walduck, 2006). No Brasil, onde foi detectado em 1930 sobre banana Maçã (Cordeiro et al., 2003), essa doença causa perdas acentuadas na produção de frutos em todo o País (Cordeiro et al., 1993), notadamente na variedade Maçã e naquelas do subgrupo Prata.pdf 202
