During storage and keeping the loss of agricultural products as well as consumption of energy to keep microclimate in storage house is perforce. During the storage of agricultural products it is necessary to test their quality in order to adjust microclimate control. Such test also requires some time and input costs. A number of methods to test quality of storage products is practically used. This article shows the possibility to use nondestructive measurement technique such as measure frequency domain characteristics of the biological objects in testing quality of any agricultural products. The hodographs of frequency transfer function of apple, potato and carrot are significantly different. That means that it is possible to find unique relationships between frequency transfer function and quality parameters of agricultural products
