Availability and information needs in the chemical contaminants domain – PortFIR assessment

Chemical contaminants (Chc) can be naturally present and/or be introduced in food and feed as result of the various stages of its production, processing and transport and/or due to environmental contamination. The analysis of Chc laboratory data allows to generate information for continuous improvement of food safety and protection of public health. In order to define priorities for development of the Contaminants Database of the Portuguese Food Information Resource (PortFIR), it was decided to identify and assess the availability and information needs on food and feed Chc of the main Portuguese stakeholders in the area.N/

Processing Contaminants in Food Production

Contaminants like acrylamide, furan or PAHs (polyaromatic hydrocarbons) as e.g. Benz(a)pyrene may be formed during food processing. All of the substances are genotoxic carcinogens, and for that reason mitigation strategies to reduce the levels are needed. Examples of the formation of the processing contaminants and factors that influence the occurrence are given as well as suggestions for mitigation

Seafood from Norway : food safety

Since Norway is a major supplier of seafood worldwide, monitoring the food safety of Norwegian fish products is a priority. This commentary gives a brief overview of the food safety of seafood from Norwegian waters. Several preventative measures during harvest/catch, processing and distribution have been established and are implemented regularly. Furthermore, comprehensive monitoring programmes to detect and quantify undesirable substances, such as heavy metals and polychlorinated biphenyls (PCBs), in Norwegian seafood are carried out. Substances with health benefits, such as omega-3 fatty acids, are also analysed. In general, evidence shows the level of undesirable substances in seafood from Norway to be low. In fact, in the majority of samples analysed, levels of undesirable substances were reported to be below the maximum limit set by the European Union (EU). This leads to the conclusion that consumption of seafood originating from Norway involves a low risk of negative health effects and that consumers can have confidence in the products they purchase.peer-reviewe

Bacteriocins: Novel Solutions to Age Old Spore-Related Problems?

peer-reviewedBacteriocins are ribosomally synthesized antimicrobial peptides produced by bacteria, which have the ability to kill or inhibit other bacteria. Many bacteriocins are produced by food grade lactic acid bacteria (LAB). Indeed, the prototypic bacteriocin, nisin, is produced by Lactococcus lactis, and is licensed in over 50 countries. With consumers becoming more concerned about the levels of chemical preservatives present in food, bacteriocins offer an alternative, more natural approach, while ensuring both food safety and product shelf life. Bacteriocins also show additive/synergistic effects when used in combination with other treatments, such as heating, high pressure, organic compounds, and as part of food packaging. These features are particularly attractive from the perspective of controlling sporeforming bacteria. Bacterial spores are common contaminants of food products, and their outgrowth may cause food spoilage or food-borne illness. They are of particular concern to the food industry due to their thermal and chemical resistance in their dormant state. However, when spores germinate they lose the majority of their resistance traits, making them susceptible to a variety of food processing treatments. Bacteriocins represent one potential treatment as they may inhibit spores in the post-germination/outgrowth phase of the spore cycle. Spore eradication and control in food is critical, as they are able to spoil and in certain cases compromise the safety of food by producing dangerous toxins. Thus, understanding the mechanisms by which bacteriocins exert their sporostatic/sporicidal activity against bacterial spores will ultimately facilitate their optimal use in food. This review will focus on the use of bacteriocins alone, or in combination with other innovative processing methods to control spores in food, the current knowledge and gaps therein with regard to bacteriocin-spore interactions and discuss future research approaches to enable spores to be more effectively targeted by bacteriocins in food settings.KE, DF, CH, PC, MR, RR are supported by the Irish Government under the National Development Plan, through the Food Institutional Research Measure, administered by the Department of Agriculture, Fisheries and Food, Ireland (DAFM 13/F/462) to PC and MR, a Science Foundation Ireland (SFI) Technology and Innovation Development Award (TIDA 14/TIDA/2286) to DF, SFI-PI funding (11/PI/1137) to PDC and the APC Microbiome Insitute under Grant Number SFI/12/RC/2273

Pendugaan Tingkat Keamanan Jagung Dengan Menggunakan Pengolahan Citra Digital Dan Jaringan Syaraf Tiruan

Food security is the main problem in food production in Indonesia. One of the reason that the food from corn is not safe to be consumed caused by contaminated by aflatoxins which produced by fungi. Determination of food contaminants is usually carried out by laboratory analysis. This method is very expensive and need a lot of time. The objective of the research was to predict the security of corn due to aflatoxin contaminant by using image processing and artificial neural network (ANN). The image of seed corn was taken by using digital camera and processed by image processing program. ANN model was developed with 10 input parameters, 20 hidden layers and 4 targets. The targets of safety levels was four such as very safe, safe, less safe and not safe. The accuracy of the model was 74%. (peng
