Effects of Variable-Frequency Vibration Stress on Chilling Injury and Storage Quality of Blueberries

Mengge Li, Huizhen Chang, Dan Li, Yang Li*

Abstract


In this study, blueberries were subjected to vibration treatments of 3 Hz (3 h), 3-4-3 Hz (3×1 h), and 4-3-4 Hz (3×1 h), then stored
at 4±0.5°C and 90%-95% humidity for 20 days. Physiological indices were measured every 3 days. The results showed that blueberries in the
3 Hz fixed-frequency vibration group maintained better quality, with chilling injury occurring on the 12th day. In contrast, blueberries in the
3-4-3 Hz and 4-3-4 Hz variable-frequency vibration groups suffered more severe damage, with chilling injury appearing on the 8th day, characterized by increased color difference (ΔE) and cell membrane permeability, elevated activities of superoxide dismutase (SOD) and catalase
(CAT), and decreased contents of anthocyanins and ascorbic acid (AsA), as well as reduced activity of peroxidase (POD). The study indicates
that variable-frequency vibration is more likely to damage blueberries than fixed-frequency vibration, providing a basis for reducing quality
loss of blueberries during transportation and storage.
