Effect of edible coatings with essential oils on the quality of red raspberries over shelf-life.

BACKGROUND: The objective of the present work was to develop strategies for increasing the shelf-life of red raspberries (Rubus idaeus L.), by preventing microorganism growth. RESULTS: Fruits coated with alginate plus lemon essential oil (0.2%) or orange essential oil (0.1%) after 15 days of storage had less red skin than the remaining samples. The less red color verified in these samples was also coincident with the lower concentration of anthocyanins at the end of the experiment as well as the lower capacity for scavenging ABTS free radicals or quenching singlet oxygen. Cyanidin and pelargonidin glucosides were found in raspberries fruits. The edible coatings supplemented with the essential oil of orange either at 0.1% or 0.2% were very efficient for controlling yeast and mold growth after 15 days of storage. To control the development of aerobic mesophilic bacteria the use of essential oil of lemon 0.2% and essential oil of orange 0.1% were the most efficient. CONCLUSION: The application of the film improved post-harvest quality of raspberry, since the addition of essential oils of citrus films promoted to the inhibitory effect of fungi and bacteria growth after 15 days of storage, without changing quality parameters. © 2016 Society of Chemical Industry.

Estratificação do risco cardiovascular em cadeirantes jogadores de basquetebol / Cardiovascular risk stratification in wheelchair basketball players

Objetivou-se estratificar fatores de risco para doenças cardiovasculares (DCV) em dez anos em jogadores de basquetebol em cadeiras de rodas. O percentual de risco cardiovascular foi estratificado pelos escores de Framingham (ERF) e de Risco Global (ERG). Dos treze jogadores avaliados, 38,46% apresentava sobrepeso e obesidade e 77%, alterações na porcentagem de gordura corporal e na circunferência abdominal. O ERF identificou 15,38% dos jogadores com risco intermediário para desenvolvimento de DCV e pelo ERG, 15,4% dos homens apresentava risco intermediário, 7,7% alto risco por diabetes e 7,7% muito alto risco por doenças ateroscleróticas. Os resultados de composição corporal demonstram uma predisposição para desenvolvimento de DCV, sendo que o ERG identificou indivíduos com alto risco e muito alto risco. Conclui-se que a identificação dos fatores de risco é útil para que ocorra uma maior prevenção das DCV e aconselhamento adequado sobre adoção de hábitos de vida saudáveis por esses indivíduos.

The objective of this study was to stratify risk factors for cardiovascular diseases (CVD) in ten years in wheelchair basketball players. The percentage of cardiovascular risk was stratified by the Framingham Score (FS) and Global Risk Score (GRS). Of the thirteen players evaluated, 38.46% were overweight and obese and 77%, presented changes in body fat percentage and waist circumference. The GRS identified 15.38% of the players with intermediate risk for developing CVD and according to GRS, 15.4% of men presented intermediate risk, 7.7% high risk for diabetes and 7.7% very high risk for atherosclerotic diseases. The results of body composition demonstrate a predisposition for the development of CVD and the ERG identified individuals with high risk and very high risk. It is concluded that the identification of risk factors is useful for a greater prevention of CVD and appropriate advice on the adoption of healthy lifestyle habits by these individuals.
