It looks like electric shock treatment works on potatoes as well as it does on patients dealing with depression.
Scientists have discovered that zapping potatoes with electricity gives the vegetable new life and vitality. In short, it makes them more nutritious. Scaled up to a commercial level, the apparently inexpensive process could give potatoes a whole new image, writes Fiona Macrae, reporting for the UK’s Daily Mail online.
Inspired by the observation that drought, bruising and other natural challenges, or stresses, led to vegetables making more antioxidants, researcher Dr. Kazunori Hironaka decided to investigate man-made ways to â€˜stress outâ€™ veggies.
Using electric and ultrasound treatments, antioxidant levels increased by up to 60 percent, the study found. Whole potatoes were dipped in salty water, to help them conduct electricity, and then zapped with a small charge for up to a half hour.
Dr. Hironaka noted that potatoes are one of the most important crops, ranking fifth in human consumption. He did not reveal whether the treatments affected the taste of the spuds.
A spokesman for the Potato Council agreed that there may be some potential to this idea of boosting the antioxidant quotient in potatoes.
Aren’t potatoes stressed out by being cut into strips and dropped in hot oil? I know I would be.
