Europe leads the way for food safety law

Europe leads the way for food safety law

| September 15, 2015 | 1 Comment

Two of this week’s news stories provide an interesting insight into how the regulatory environment in which the food industry must operate varies around the world. In the USA, the FDA announced that it had finalised two of the seven major rules contained in the Food Safety Modernisation Act (FSMA) that was signed into US […]

EU researchers highlight varying regulatory approaches to nanotech in food

| September 15, 2015

Newly published research by the European Commission Joint Research Centre (JRC) has revealed big differences in how the safe use of nanotechnology in food and feed production is regulated in different parts of the world. The research is based on information gathered by the JRC, RIKILT-Wageningen and the European Food Safety Authority (EFSA) from published […]

Oregano oil nanoemulsion could help control pathogens on fresh produce

Oregano oil nanoemulsion could help control pathogens on fresh produce

| May 5, 2015

Researchers at Wayne State University in the USA have been investigating the use of nanoemulsions of antimicrobial essential oils from plants as an alternative to chlorinated water for decontaminating fresh produce. The research team looked at essential oils from plants such thyme, oregano and clove as natural antimicrobials that could potentially reduce levels of bacterial […]

Researchers develop meat spoilage nano-sensor

Researchers develop meat spoilage nano-sensor

| April 17, 2015

A team of chemists from the Massachusetts Institute of Technology (MIT) in the USA has developed a new portable sensor based on chemically modified carbon nanotubes, which is able to detect the volatile chemical by-products of microbial meat spoilage. The MIT researchers modified the carbon nanotubes with a metalloporphyrin containing a central cobalt atom bound […]

MEPs call for nano-food moratorium

MEPs call for nano-food moratorium

| December 2, 2014

Members of the European Parliament (MEPs) have amended European Commission plans for a simplified authorisation procedure for novel foods and proposed a moratorium on the use of nano-materials in food until their safety has been fully assessed. The draft legislation is intended to encourage food innovation in the EU and sets out clear deadlines and […]

Antimicrobial edible films could improve food safety

Antimicrobial edible films could improve food safety

| May 6, 2014

Researchers at Penn State College of Agricultural Sciences in the USA have published the results of a study to investigate how edible films incorporating antimicrobial compounds affect the growth of pathogenic bacteria on meat products. Experiments with edible films made from pullulan and incorporating essential oils from oregano and rosemary and zinc oxide and silver […]

Research highlights nano-silver risks

Research highlights nano-silver risks

| February 28, 2014

A newly published study by researchers at the University of Southern Denmark has demonstrated that nano-silver particles are able to enter human cells, producing potentially harmful free radicals and changes in certain cell proteins. The researchers, led by Associate Professor Frank Kjeldsen and Dr Thiago Verano-Brava, looked at the effect of two sizes (100nm and […]

New biosensor could speed up foodborne pathogen detection

New biosensor could speed up foodborne pathogen detection

| January 30, 2014

A newly published study by a team of researchers from the USA, UK and Thailand has developed a potentially rapid new detection method for pathogenic bacteria using a biosensor made from an array of microcantilevers. The “nanomechanical cantilevers” made from silicon are fixed at one end and have phage-derived peptides attached to them. These peptides […]

Study raises concerns over silver nanoparticles in food

Study raises concerns over silver nanoparticles in food

| September 15, 2013

Recent research by scientists at the University of Missouri in the USA has highlighted a potential hazard to human health from the increasing use of silver nanoparticles as a pesticide in agriculture. The team, led by Associate Professor of Food Science Mengshi Lin, developed a number of different techniques to detect silver nanoparticles, including electron […]
