D&T Farm said this involved slowly cooling the banana growth cells to -60C (-76F) before thawing them.

“It was created following research conducted by Setsuzo Tanaka who worked on this for a long time as a hobby,” a spokesman for the farm said in an email.

“The motivation for its development was the fact he wanted to eat a banana that was delicious and safe: people can eat the peel because it is cultivated organically without chemicals.”
