Can LEDs in refrigerators enhance the nutritional value of vegetables?

“Increase Vitamins, Preserve Freshness In order to enhance vegetables nutritional value, Mitsubishi Electric has installed a photosynthesis LED in the crisper, creating the world’s first refrigerator that utilizes photosynthesis to enhance the nutritional value of your vegetables. For the first time in the industry, we are introducing an amazing function that increase vitamins in vegetables. Vegetables are alive even after harvesting. LED lights is irradiated during preservation, and photosynthesis is encouraged, so nutritions such as vitamin C are increased and foods are preserved with vitamin C that are 1.5 times as good as before. Starting from the concept of controlling nutrition loss, we have been able to achieve increasing nutritional values in a totally new-concept refrigerator. Research showed that the light’s color was important: The orange light creates chlorophll in vegetables without inducing them to grow. A small bank of LEDs in the roof of the vegetable drawer produces lights at a wavelength of 590 nanometers (orange). Mitsubishi Electric found that after three days, the vitamin C level in broccoli sprouts stored in their new refrigerator was 50% higher than in a conventional refrigerator.”

Here’s my question and subsequent challenge:

Can this possibly have value as claimed? I’m a bit dubious, as photosynthesis (as I understand it) cannot continue once the plant and fruit have been seperated (no leaves). But there may still be benefits, even if just to assist in efficacy.

So, if there is SOME benefit, this doesn’t sound too difficult to make at home, as long as you know what you are doing: how to wire into an existing fridge, what LEDs to use, etc.
