New US technology which can gauge not just the ripeness of fruit but also inspect it for residues has been unveiled to the Washington State Horticultural Association.
The north west US is one of the largest deciduous national production areas for apples, pears, and cherries. The system uses electromagnetic waves and Wal-Mart has asked its suppliers to consider the potential.
The North West Pear Bureau has also completed successful tests on a New Zealand system which monitors the ripeness of pears. It believes four million cartons of Anjou will be labelled within two to three seasons.
