Compositional changes and spoilage in fish ‐ an introduction

Presents the compositional and spoilage changes in fish ‐ useful for determining the freshness for eating. Chemical and microbiological methods are focused on. Breakdowns in chemical components lead to detectable changes ‐ odour, flavour and texture. Changes to the fats, protein, nucleotides, non‐protein nitrogen compounds and enzymes are examined. These means are more valid when dealing with preserved and frozen fish and can give accurate assessment as to fish quality.</jats:p

The safe use of recycled and reused plastics in food contact materials ‐ part II

The use of plastic as packaging material has been increasing at an exponential rate with time over the past decades. After use, most of the plastic waste has traditionally been disposed of into landfills, which in turn have led to serious environmental concerns, but landfill sites are decreasing. Discusses options such as recycling and reuse of post‐ consumer plastics, which may contribute to solving these environmental problems and touches on relevant European legislation.</jats:p

Compositional changes and spoilage in fish (part II) ‐ microbiological induced deterioration

Covers the quantitative and qualitative aspects of micro‐organisms present in fish and the factors which affect sea food quality. Several methods can be employed to counter deterioration ‐ low temperature, storage, dehydration, canning, modified atmosphere, packaging, irradiation and chemical or biological preservatives.</jats:p

Chromium in food, nutrition and health ‐ an introduction

Describes chromium’s importance in nutrition and health, pinpointing its sources in diets and facts about its absorption in humans. Outlines the body’s ability to store chromium and the function of the element. Reports on current recommendations of safe and adequate levels of intake. The symptoms of chromium deficiency are discussed as are the toxic effects of too high an intake. Concludes with recommendations for required further research.</jats:p
