The paper presents the results of research on the assessment of mechanical impact in the form of vibrations on the overall quality of raspberry fruits after harvesting, in the context of conditions of their transport to the consumer and the processing plant. The degree of compaction of the raspberry fruits layer was determined in the course of test carried out in laboratory conditions, and the amount of juice leakage resulting from vibrations, to which raspberries were subject, was measured. It was demonstrated that mechanical impact, in the form of vibrations, on the layer of raspberry fruits has a substantial impact on the quantity (mass) of juice leakage, which is smaller in the case of cooled fruits, and significantly bigger in the case of fruits not subject to cooling immediately after harvesting and stored at ambient conditions.
