DURING 2007, all laying hen producers within the McDonald’s Restaurants UK supply base (McDonald’s Restaurants UK source eggs from free-range UK producers) were required to plant, if not present already, 5 per cent of the total range area in trees. Noble Foods supply free-range eggs into a variety of food retailers not all of which require tree cover on the range. In this study, the authors inv...

Utilization of natural products is radically changing. Changes were mainly due to the outcome in the market of a plethora of new food supplements, and in particular those generally named botanicals for their common plant origin. The validation of these novel products needs powerful analytical devices tailored for the study of herbal extracts in order to assess composition and face their natural...

Oviposition and predation levels by Speciomerus revoili bruchid beetles were quantified on fruits and seeds of the macaúba palm, Acrocomia aculeata, collected from below mother-trees within the Sarah Kubitschek Park of Brasília, DF, Brazil. A maximum of 12 eggs per fruit were found, with high variations observed between samples. No clear pattern was found for the distribution of the number of e...

background: due to high content of unsaturated fatty acids, trout is susceptible to oxidative spoilage. in this study, the effects of thymus vulgaris essential oil (eo) and extract on oxidative stability of cooked rainbow trout fillet during four months frozen storage period were investigated. methods: three groups of fish fillets were treated with thyme eo and three other groups were treated w...

Genetically Modified (GM) plants are rapidly entering the food system in the world. These modifications, which are intended to enhance plant productivity and product quality, make use of genetic engineering. This technology offers enormous potential for creation of plants optimized for food and fiber production in support of human needs. However, there is increasing concern about the use of gen...

The aim of the research project was to identify ways to maximise the flexibility of the plant by varying equipment utilization, while guaranteeing a certain level of profit. A case study was conducted at a company that makes various types of food additives, which are produced in a multi-product multipurpose batch plant. At the time of the research, market demand was exceeding the company's prod...

A convenient, quick and cost-effective method to detect the presence of allergenic components and pathogens is one of the greatest challenges confronting the food processing industry. Biosensors are emerging as a highly promising tool for rapid diagnosis of pathogens and allergenic components in foods. Detection of contaminants, verification of product contents, product freshness and monitoring...

Dietary and clinical surveys carried out in India, Africa and in several countries elsewhere, in Asia and South America, have shown that the diets of large numbers of people are deficient in many essential nutrients such as proteins, vitamins and minerals (Patwardhan, 1952; Autret & Behar, 1954; Gopalan & Ramalingaswami, 1955 ; Brock & Autret, 1952). Protective foods such as milk, eggs, fish an...

Introduction Decision points based on food-specific IgE antibody concentrations have been proposed and are used in the clinic, in order to predict reactivity to foods and reduce the number of high risk food challenges. In the process of screening for eligibility in a study, we started carrying out open food challenges to boiled egg in children with sensitization to egg proteins, independent of ...

Benzene is a volatile organic compound known to be carcinogenic to humans (Group 1) and may be present in food. In the present study, 455 food samples from the Belgian market were analyzed for benzene contents and some possible sources of its occurrence in the foodstuffs were evaluated. Benzene was found above the level of detection in 58% of analyzed samples with the highest contents found in ...
