Paper discusses the effect of vibrations at different frequencies on changes in the content of ascorbic acid and citric acid in blueberry fruit. Fruit was tested under incomplete maturity. The chemical com-position of fruits was compared immediately after harvest, stored and subjected to vibrations. The purpose of the research was to deter-mine the effect of vibrations on the degree of fruit ripeness. Studies have shown that vibrations at low frequencies did not affect changes in the chemical composition of blueberry fruit. Vibrations with a frequency of 28 Hz caused significant changes in the parameters tested in the fruit.
