る。When performing a measuring operation with the softness measuring device (handy HIT) 1 for fruits and vegetables having such a configuration, the measuring device 1 is held in one hand and the kiwi fruit is held in the other hand. The tip 5a of the plunger 1
The kiwifruit is applied almost perpendicularly to the surface of the kiwifruit (for example, substantially at the center in the longitudinal direction having an oblong shape), and is slowly pressed until the tip 3a of the guide comes into contact with the kiwifruit surface. Then, the plunger 5 moves while compressing the spring 6 due to the resistance of the kiwifruit at that time, and the maximum displacement of the kiwifruit, that is, the softness,
The pointer 2a of the dial gauge 2 indicates the scale 2b. This numerical value indicates the softness of the kiwi fruit. At this time, the surface of the kiwifruit does not dent at most 1 mm or more, so that the quality is not adversely affected. When the tip 5a of the plunger and the tip 3a of the guide are difficult to reach from the kiwifruit, the tip 5a of the plunger and the indicating needle 2a of the dial gauge 2 are set.
Returns to the original position by the elastic force of the spring 6. In this way, the softness of the kiwifruit is continuously measured.

The result of obtaining the correlation with the measurement result by the T counter (high-precision measuring device) is shown in the graph of FIG. As is clear from this graph, the correlation coefficient was r = 0.83, and it was confirmed that the correlation coefficient can be sufficiently used for kiwifruit quality control and the like. From the relationship between the displacement of the kiwifruit and the softness, the range of the measurable softness was divided equally into 100 parts on the dial gauge (scale 2b) in the measuring device (handy HIT) 1 to determine the softness. As a result, 20 or less is firm and suitable for shipment, 40-60
It was judged that it was about to be eaten, and that 80 or more was soft (overmature = unsuitable for shipment) .
