  This work will aim at carrying out microbiological analysis of beef hamburgers, which will determine if this product is suitable or not for consumption in the hygienic and sanitary point of view, in other words, if conform the standards set by the relevant national legislation. To evaluate the microbiological quality, it will be collected samples of beef hamburgers in supermarkets in the …

• Abstract

  The deuterium- and oxygen-18-doubly labeled water technique, is the gold standard for determiningtotal energy expenditure (TEE). The progress of researches with this technique happened in parallel with many other analytical techniques using isotopes in aqueous samples. A new analytical method is being implemented at the Stable Isotope Center (SIC) of the Institute of Biosciences ofBotucat…

• Abstract

  Traceability is the ability to find out in the history, use or origin of certain food. It is fundamental for the concept of food safety, quality and animal welfare to assure the authenticity and origin of food and final products (meat, milk, eggs), then consumers may know and evaluate the productive chain of the food they consume, as the population expects more reliable information from p…

• Abstract

  Since the crisis of bovine spongiform encephalopathy or "mad cow" disease, and recent outbreaks of avian influenza in Japan, Russia and Europe, concerns about the use of poultry by-products in animal feeding has increasing. Because of the consumer's worry about the safety of food, were created by countries new laws and barriers to boost the consumer confidence in markets. However, due to …

• Abstract

  The use of animal byproducts in feed have been widely discussed today. In part this has been due to insecurity consumer after the outbreaks of "mad cow" and the problems of products contamination. Allied to this, religious and cultural influences of different markets buyers of chicken dictate trends regarding the production and products consume such as, for example, green or alternative …

• Abstract

  The demand for organic food has increased sharply in recent years, especially dairy products. Therefore, procedures for authentication of then, without knowing their origin, have a great importance for consumers to assure that food they are purchasing is genuinely organic. However, it is necessary more researches about analytical parameters that distinguish between organic and conventiona…
