Overview of Seafood Research at Ashtown Food Research Centre (1990 - 2007)
End of project reportIn recent years, the Irish seafood industry has faced stringent quotas and dwindling fish stocks. The introduction of fish farming added a new dimension but falling prices also created difficulties for this sector. However, the recent report of the Seafood Industry Strategy Group on ‘Steering a New Course’ and the Sea Change Programme of the Marine Institute will add new impetus to the industry. The current report summarises R&D on seafood conducted at Ashtown Food Research Centre (AFRC) in the period 1990-2007 and represents a major portion of seafood R&D conducted nationally during that period.Thanks are also extended to the European Union
(and especially the SEAFOODplus project), Bord Iascaigh Mhara, Marine
Institute, Enterprise Ireland and various seafood companies for their support
and part-funding of elements of this research
Adding Value To Under utilised Fish Species
End of project reportTightening fish quotas and supply shortages for conventional species are causing major difficulties for both fishermen and seafood processors. There is a need, therefore, to explore the potential of underutilised fish species both as fillets or portions and as added-value products. The current project at Ashtown Food Research Centre (AFRC) addressed this issue for a number of underutilised species via (a) sous vide processing (with savoury sauces),(b)marinating (salt- and sugar-based marinades) and (c) via a combination of freeze-chilling and modified atmosphere packaging (MAP).A range of physico-chemical and sensory tests was conducted on the products and their shelf-life status was also determined.National Development Plan (NDP
Status Report on Acrylamide in Potato Products
End of Project ReportThis status report was conducted as part of Task 1 of a research project (RMIS No. 5265) on the development and quantification of acrylamide in potatoes and potato products funded under the Food Institutional Research Measure (FIRM) of the Department of Agriculture and Food as part of the National Development Plan. Teagasc acknowledges the support of theDepartment of Agriculture and FoodAcrylamide is a toxin that can potentially occur in high concentrations in heated starchy foods especially potato products such as crisps and french fries. In model systems isotopic substitution studies have demonstrated that acrylamide is formed via the Maillard type reaction between the amino acid aspargine and a carbonyl source such as the reducing sugars glucose and fructose. Levels of acrylamide in cooked potato products are primarily influenced by the levels of reducing sugars in the product and this in turn is influenced by storage time, temperature and variety of potato used. During cooking acrylamide formation begins to occur at temperatures above 100°C and increases up to temperatures of 220°C but decreases thereafter due to thermal degradation of the compound. Risk assessment studies on acrylamide intakes have been conducted in a number of countries and mg/kg body weight daily intakes have been estimated to be between 0.2-0.8. Adequate analytical techniques exist for quantification of acrylamide in potato and are mainly based around liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) and gas chromatography mass spectrometry (GC-MS) techniquesDepartment of Agriculture, Food and the Marin
Acrylamide formation in potato products
End of Project ReportAcrylamide, a substance classified as a potential carcinogen, occurs in heated
starchy foods at concentrations many times in excess of levels permitted in
drinking water. Early surveys indicated that levels of acrylamide in potato
products such as French fries and potato crisps were the highest of the
foodstuffs investigated. The present project addressed this issue by
determining levels of acrylamide precursors (asparagine and reducing sugars)
in raw potatoes and levels of acrylamide in (i) potato products from different
storage regimes, (ii) spot-sampled potatoes purchased from a local
supermarket, (iii) samples that received pre-treatments and were fried at
different temperatures and (iv) French fries reheated in different ovens.A risk
assessment of the estimated acrylamide intake from potato products for
various cohorts of the Irish population was also conducted
Developing Sous Vide/Freezing Systems for Ready-Meal omponents
End of project reportSous vide cooking involves sealing raw or par-cooked food in a vacuumised laminated plastic pouch or container, cooking by controlled heating, rapid chilling and then re-heating for consumption. The chilled storage period is up to 21 days at 0 to 3oC. The recommended thermal process for sous vide products is 90oC for 10min or its time-temperature equivalent. Concerns about the safety of sous vide products, mainly due to the potential for temperature abuse in the chill chain, has prevented the widespread use of this technology. The role of the current project, therefore, was to investigate sous vide cooking followed by freezing, as a safe alternative to sous vide/chilling for 10 ready-meal components i.e. carbohydrates (potatoes, pasta, rice), vegetables (carrots, broccoli) and muscle foods (salmon, cod, chicken, beef and lamb).National Development Plan (NDP
A Structured Debate on the Safety of Red Meat
A structured debate was held at The National Food Centre, Teagasc between 17 consumers and 3 scientists/experts on the safety of red meat as part of the ongoing FLAIR-FLOW 4 dissemination project. The areas of BSE (bovine spongiform encephalopathy), CJD (Creutzfeldt-Jacob disease), meat and bonemeal, meat traceability, ritual vs conventional slaughter, antibiotic residues in meat, the effects of freezing and cooking on E. coli 0157:H7, and lastly crosscontamination of meat at retail outlets were debated in-depth. The consensus was that red meat is safe, provided the necessary safeguards and codes of practice are adhered to. The interaction, intensity and depth of the debate was excellent and both the consumers and scientists/experts found it an informative exercise.European CommissionFLAIR-FLOW 4 dissemination projec
Feeding the Recovery: FoodDrinkEurope leads the way
30th Anniversary Congress of FoodDrinkEurope, Brussels, Belgium, 17 - 18 October 2012FoodDrinkEurope represents Europe’s food and drink industry and has as its members 25 national food federations, 26 European food sectors and 19 companies. Its mission is to facilitate the development of an environment in which all of Europe’s food and drink companies, whatever their size, can meet the needs of consumers and society, while competing effectively for sustainable growth (www.fooddrinkeurope.eu/) FoodDrinkEurope evolved from the CIAA (Confédération des Industries Agro-Alimentaire de l’EU, which was established in 1982 and became FoodDrinkEurope in 2011.Deposited by bulk impor

Relating starch properties to boiled potato texture
Basic information on starch properties may help to explain the different textural characteristics of potato cultivars, and also their suitability for different forms of processing. The study involved tests on both raw potatoes, and on starch separated from potatoes, and embraced three main activities:
(i) to relate boiled-potato texture with the other test variables;
(ii) to develop a rapid crush-test for assessing cooked-potato texture;
(iii) to study the effect of chilling and freezing on the development of
resistant starch (RS) in boiled potatoes.Teagasc acknowledges with gratitude grant aid under the Food Sub-Programme of the Operational Programme for Industrial Development. The programme is administered by the Department of Agriculture and Food supported by national and EU funds
