✦ Synopsis

Lipase-catalysed irreversible conversion of jatropha oil to ethyl esters with diethyl carbonate.

Transesterification of jatropha oil and diethyl carbonate in a solvent-free system with Lipozyme TL IM, Lipozyme RM IM, or Novozyme 435 has been examined. Optimum reaction conditions are reaction time 13.3 hours, temperature 44.58C, lipase amount 13.7%, carbonate to oil ratio 3.75:1, with no need for added water, and use of Novozyme 435. Under these conditions the yield of ethyl ester was 96.2%. /fg

The term phenolics covers about 8000 natural compounds all containing one or more phenolic hydroxy groups and some times also a carboxyl group. Examples include flavonoids, stilbenes, and tannins. They may react in three ways to exhibit antioxidant behaviour: by hydrogen atom transfer, by single ele

## Effect of c-ray irradiation on the fatty acid profile of irradiated beef meat It is known that c-ray irradiation of beef meat leads to changes in fatty acid composition especially of polyunsaturated acids. The authors show that these changes can be determined by 1 H NMR more easily than by the p

Do production methods (intensive or free range) affect fat and fatty acid composition in chicken meat? Consumption of poultry meat in the UK has risen from around 15 to 375 g/person/week in the last 60 years. Fat content varies with the portion of meat consumed and particularly on the presence or a
