• Extending the shelf life of fresh sliced mushrooms

      The Irish mushroom industry is expanding rapidly as is the demand for sliced mushrooms. To increase the competitiveness of Irish mushrooms for export their shelf life should be extended to compensate for the time lost in transit. The aim of this project was to extend the shelf life of sliced mushrooms by 50 % using novel processing treatments and / or packaging. A method was established to assess the effects of different treatments on mushroom quality. This method was followed using solutions of citric acid, hydrogen peroxide, EDTA, nisin, diacetyl, vitamin E, ascorbic acid, rosemary extracts and sodium metabisulphite.
    • The quality of under-utilised deep-water fish species

      Brennan, Martine H.; Gormley, Ronan T.; European Union; Marine Research Measure (Teagasc, 1999-09)
      The quality of twenty-three frozen under-utilised fish species was examined. The species were spot samples of deep-water fish caught near the Rockall Trough by the Fisheries Research Centre. Their basic composition was 80.8 - 86.4% water, 9.8 - 25.2% protein, 0.18 - 16.2% lipid and 0.7 - 2.0% ash. Lead, cadmium and mercury concentrations were determined for six species and were much lower than the maximum levels set in 1992. Ammonia levels were unacceptably high in three shark species.
    • Upgrading the cold chain for consumer food products

      Gormley, Ronan T.; Brennan, Martine H.; Butler, Francis (Teagasc, 2000-12)
      The prepared consumer foods sector in Ireland is undergoing sustained dynamic growth. Products that are distributed chilled or frozen require a cold chain and there is potential to increase product quality by optimising the cold chain. This potential prompted the current study.
