For decades it was a given that a fridge light turns off as soon as the door was closed, but fresh thinking at Mitsubishi Electric was the catalyst for keeping the light on, at least in the vegetable case. Mitsubishi Electric has developed a new technology, Vitalight, to increase the vitamin content of vegetables with the ultimate aim of keeping food fresher for longer. Energy efficient amber LED lights at the back of the vegetable case mimics photosynthesis and creates chlorophyll in vegetables, allowing them to absorb energy from the light, increasing Vitamin C levels for fresher, tastier food.
