Abordaje práctico sobre cómo mejorar el bienestar en los bovinos

Current challenges of humanity require a new paradigm for animal production, and invest time and attention to the development of new production techniques that take into account the principles of sustainability and animal welfare science. To do this, we must be committed to promoting animal welfare and health, ensure environmental sustainability, consumer satisfaction and profitability for producers. To change our relationship with animals there is no need for changes in market conditions or large investments, it is enough to know better the needs of the animals we raise, the management system adapted to its characteristics. Even in the most favorable management conditions, on farms that have technological resources and trained personnel, there is much to change, especially in the daily management of the animals. Some of the risks more evident in the traditional systems of beef production are: problems during parturition, morbidity and mortality of calves, lack of shade in the pastures, improper handling of animals, risk of injury, inadequate infrastructure, poor management practices during routine processing (marking, castration, vaccination, dehorning), poor welfare during loading, transport, unloading and slaughter. To remedy this, you can adopt good management practices, which have been shown to reduce risk and improve the welfare of cattle in different stages of the production chain. The objective of this review is to show some of the risks that reduce the welfare of cattle and examples of how the adoption of best management practices impact on improving the productivity of these production systems. Finally, some indicators for assessing welfare in production systems are shown.

Influencia de la deshidratación osmótica y de la adición de cloruro de calcio en la conservación de kivis minimamente procesados

Este trabalho teve como objetivo estudar o efeito combinado da desidratação osmótica e a influência do cloreto de cálcio em rodelas de kiwi submetidas ao processamento mínimo. Amostras com e sem desidratação osmótica foram armazenadas a 5 °C em embalagem PET. A adição do cloreto de cálcio foi realizada durante a desidratação osmótica. Foram avaliados a perda de peso, acidez, sólidos solúveis, pH, umidade, coliformes, fungos e leveduras nas amostras até 15 dias de armazenamento. A avaliação microbiológica e sensorial definiu a vida de prateleira do produto. Os resultados mostraram que o pré-tratamento osmótico com adição de cloreto de cálcio aumentou a vida útil em até 15 dias, enquanto as rodelas tratadas por osmodesidratação, sem a adição do sal apresentaram vida útil de 12 dias. Sensorialmente, os consumidores preferiram as rodelas de kiwi processadas com pré-tratamento osmótico e adição de cloreto de cálcio.

Influencia de la deshidratación osmótica y de la adición de cloruro de calcio en la conservación de kivis minimamente procesados

Este trabajo tubo como objetivo estudiar el efecto combinado de la deshidratación osmótica y la influencia del cloruro de calcio en rodajas de kivi sometidos al proceso mínimo. Muestras con y sin deshidratación osmótica fueron almacenadas a 5 °C en embalajes PET. La adición de cloruro de calcio fue realizada durante la deshidratación osmótica. Se evaluaron la pérdida de peso, acidez, sólidos solubles, pH, humedad, coliformes, hongos y levaduras en las muestras hasta 15 días de almacenamiento. La deshidratación osmótica consistió en la inmersión de las rodajas de kivi en solución de sacarosa a 60% y en solución de sacarosa (60%) con adición de cloruro de calcio (0,1 M), ambos tratamientos se realizaron a temperatura ambiente (25 °C) por 24 horas y relación fruta:solución de 1:5. Los resultados mostraron que el pré-tratamiento osmótico con adición de cloruro de calcio aumentó la vida útil hasta 15 días, en cuanto las rodajas tratadas por osmodeshidratación sin adición de sal presentaron vida útil de 12 días. Sensorialmente, los consumidores prefirieron las rodajas de kivi procesadas con pré-tratamiento osmótico y adición de cloruro de calcio.

Aspectos tecnológicos dos substitutos de gordura e suas aplicações em produtos lácteos

The consumption of fat related to the incidence of diseases has motivated the development of food with less or even no fat. However, fat is important for the full functioning of the human body and sensory characteristics of food. Therefore, making food with little or no fat and at the same time maintaining the desired quality is a challenge for the industry. Fat substitutes were created to achieve this objective. Fat substitutes can be more effective in their applications when mixtures of different types of them are used. The number and variety of these ingredients are still growing, expanding options of choice when a fat substitute is required in a certain type of food. Considering the importance of fat substitutes nowadays, this paper presents an overview of functions and implications of fats in the human body and food, the terminology used to refer to fat substitutes, the categories of different types of fat substitutes available in the market and their applications in dairy products.

Avaliação da qualidade de óleos de fritura utilizados em restaurante universitário

Frying is a widely used method of preparing food, because it is a very fast and convenient process, and because it provides specific characteristics of color, flavor, odor, and texture, besides having great consumer acceptance. Therefore, the interest in the physiological effects that oils heated at high temperatures can cause to the human body arises. The aim of this work was to analyze the levels of frying used oil alteration in different kinds of foods served at the university restaurant at “Instituto de Biociências, Letras e Ciências Exatas” (IBILCE), in São José do Rio Preto-SP. In addition, it aims to make the restaurant aware of the good ways to fry and the commitment of providing good quality food to students and professionals of the Institute. With this purpose, determination of total polar compounds, conjugated dienoic acids, peroxide value, and fatty acid profile were analyzed. Two rapid tests were also used: 3M Fat Monitor and Oil Test kit. The results were compared with limits recommended for the disposal of oils and fats used in frying by the Brazilian Health Surveillance Agency (ANVISA), by other countries, and by other researches. Thus, it was concluded that the university restaurant provides the consumers with fried food of good quality, since none of the analyses showed results above recommended, although there is a need of improvement in the quality control of the oil used, in order to avoid unnecessary costs to the university restaurant.

Reflexões sobre o conceito de atendimento humanizado em Odontologia

Humanization at dental care is highly important due to uneven relation between scientific / technical advances in dentistry and thequality of human contact. The dental treatment goes beyond the field of scientific knowledge. Therefore, the dental treatment requiresbalance among technical skill, scientific training, and humanist vision of health promotion. Contemporarily, humanization is understoodas tripod based on user's rights, dental practice and organization of a humanized model. Curriculum integration of ethical, humanistic,scientific and technical contents is an important and current challenge on teaching / learning process for professionals at Dentistry. Thispaper aims to, guided by the literature review, to present some considerations on human care in dentistry, with emphasis on theimportance of professional /patient relationship for promoting oral health. It is suggested that dentists reflect on the urgent need ontheoretical basis of humanization and patient-professional relationship for health care.Descriptors: Humanization of Assistance; Dental Staff

A estética da imagem na TV digital

This text reflects on the techniques and the process of image production and its artistic composition to digital television in high defini- tion, whereas the 4:3 and 16:9 formats will exist until shutdown of the analog signal. Within this period, consumers of television programming that have analog receivers will continue to see the images in 4:3 format. That fact determines that the productions in high definition, while capturing images with larger viewing area and have high contrast ratio (>1000:1) must be main- tain the elements of visual storytelling within the smallest area and with the contrast ratio of the analog tv (30:1), at the risk of distorting visually the messages produced by the directors.
