BluApple works by absorbing ethylene gas, which is given off naturally by fruits and vegetables. If ethylene gas builds up in your food storage area, it speeds the ripening process and accelerates decomposition. Entrepreneur Timmy Chou, who founded BluApple, was inspired by the science applied for years to prevent spoilage in industrial environments like ocean liners, trucks and warehouses. He created a consumer product that makes use of the same non-toxic active ingredient (sodium permanganate). Each BluApple can absorb ethylene gas in a typical home refrigerator, produce bin or storage container for about three months (after that, refill packets are available). Simply place a BluApple where you keep your fruits and vegetables, and then sit back and enjoy them. . . for much longer.
