Researchers at Michigan State University are attempting to develop a way to tell if chestnuts are rotten without opening them.
The aim is to create a method by which it is possible to detect internal decay to ensure that produce reaching the shelves is of high quality.
So far the research seems to favor CT scans over X-rays, MRIs and other techniques trialed.
Known as CT, computerized tomography combines a series of X-rays taken from different angles and computer processing to create cross-sectional images.
Michigan is the leading chestnut-producing state in the U.S.
