Jellied eels are a traditional London snack, where eels are sliced and boiled in water with herbs, then covered in gelatine to make a jelly. Packaging Automation said it adapted its tray sealer for London based eel firm F. R. Bradley, adjusting the temperature and tray shape for the eel tins. Another important feature of the sealer is that it can cope to a wet product, the company said. Dax Bradley, spokesperson for F. R. Bradley, told FoodProductionDaily.com that allowing for wet products is a very important feature in a tray sealer, as liquid often overspills from its tin when the product is being processed. "When filling pots of jellied eels jelly is filled to the top," he said. "Inevitably, some is then going to fall onto the tray below." Other features of the tray sealer include a film feed and heat sealing tools, and it is easy to clean and service, Packaging Automation claims. According to Bradley, his firm needed to improve their processing equipment after UK demand for jellied eels shot up 40 per cent. One reason for the increase is as the fact that eels have a high level of omega 3, he said. Omega-3 fatty acids are a family of polyunsaturated fatty acids associated with a reduced risk of numerous health problems, including strokes, diabetes, heart disease and cancer. There is also a trend of consumers looking to more old-fashioned or traditional British foods, Bradley added. Packaging Automation was established in 1963 and is the UK's leading manufacturer of heat sealing machinery for the food industry. Since the creation of the PC182 in 2003, other food companies that have adapted the machinery to their operations include Glanbia, Baby Chef and Sun Valley Foods.
