The public-health community views mandatory Front-of-Pack (FOP) nutrition labels and nutritional taxes as promising tools to control the growth of food-related chronic diseases. This paper uses household scanner data to propose an ex-ante evaluation and comparison of these two policy options for the fromage blanc and dessert yogurt market. In most markets, labelling is voluntary and firms displ...

The purified capsids of echovirus I2 were found to contain radioactivity when radioactive glucosamine was provided for virus-infected cultures. Radioactivity was identified with glucosamine, after recovery from the virus particles by acid hydrolysis and paper chromatography. Although the label was not removable from the isolated virus particles without destruction of virus, polyacrylamide gel e...

The majority of vitamin B6 in the body is in skeletal muscle, bound as the cofactor pyridoxal 5'-phosphate to one abundant protein, glycogen phosphorylase. Previous work has established that radiolabelled vitamin B6 can be used as a turnover label for glycogen phosphorylase. In this study, a stable isotope derivative of pyridoxine {dideuterated pyridoxine; 3-hydroxy-4-(hydroxymethyl) -5-[hydrox...

Regulation (EC) No 1829/2003 on GM food and feed foresees labelling requirements. Decisions on labelling are taken by risk managers with the aim of offering the consumer an informed choice and are outside the scope of EFSA’s work. With the letter of 15 March 2007 (ref. SANCO/E1/SG/cc(2007)D/510144), the European Commission informed EFSA about a petition to label food products (such as meat, mil...

In the reaction catalysed by deoxyribose 5-phosphate aldolase (2-deoxy-D-ribose 5-phosphate acetaldehyde-lyase, EC 4.1.2.4) from Salmonella typhimurium, almost complete equilibration of the methyl-group protons of the product, acetaldehyde, occurs before its release from the enzyme surface. This phenomenon does not allow the stereo-chemical course of the reaction to be determined by using hydro...
