Sous Vide Tools has launched Sustainapouch, a range of plastic-free compostable chamber vacuum pouches, which it believes to be an industry first.
One of the most common concerns relating to sous vide cooking is the use of plastics, but these new pouches allow the user to dispose of them in the same way that they dispose of food – into the food waste stream, or into their home compost bin.
Made from rice, potatoes, corn, and a fossil fuel copolymer, they are designed for sous vide cooking, as well as steam cooking, microwaving, or pan boiling. After use, the chef should remove any non-compostable contents and add to the food waste stream, or compost bin. The pouches are said to take up to 6 months to disintegrate but can then be used on the garden or vegetable patch.
At 80mu (microns) the food-safe, compostable pouches are designed to be thicker than a standard alternative and can withstand the temperatures of sous vide cooking. This means that they should function in temperatures of up to 85°C for 12 hours, whereas other pouches could swell and delaminate in these conditions. They also come with a globally recognised certification for sustainability.
Available in packs of 200, there are five different sizes of bag in the range – 150mm x 250mm, 200mm x 300mm, 250mm x 250mm, 300mm x 300mm and 300mm x 400mm.
