Tesco introduces innovative new food packaging
The Indian curry dishes, made by S&R Foods, use MicVac packaging which also does not require consumers to pierce the film prior to placing in the oven or to stir the product half way through the cooking time.
The technology works like a mini pressure cooker with the trays of food being covered with a film prior to cooking which acts as a vacuum seal to retain the flavours and nutrients. It also stops bacteria from entering the trays. A valve is then applied to the film which lets out a whistling noise to indicate that the food is thoroughly heated.
MicVac agent Andrew Niznik told the Grocer magazine: "You put the product in the microwave, don't have to stir it halfway through, hear it whistle and it's ready. It's a step change in the food industry."
He added: "It's a clean product and under vacuum so there's no chance of listeria. We've got a Michelin chef that's been using it in Sweden."
Tesco is the first major UK supermarket to use the technology although S&R featured it in the Whistling Chef range it developed for Makro last year.
