抄録

The instrument and control system for measurering the quality of the farm products non-destructively and in real time was developed and the frequency response functions of the farm products were estimated through random excitation. The frequency response function was represented parametrically. Since this parametric model was the non-physical and multi-variable one, then the Mahalanobis generalized distance was introduced as the measure for describing the quality change during storage. And the new technique for the quantitative judgement of the farm products was proposed.<br>The experiments were conducted with the Japanese pears of NIJISSEIKI. The results obtained suggested that the quality changes during thirty or more days' storage were almost detectable.
