Table 1. Pterostilbene content and enrichment ratio in blueberry peels after high pressure treatment

Pressure	Content (μg/g)
Untreated	0.25c±0.031)
2 MPa	0.33a±0.05
10 MPa	0.33a±0.03
20 MPa	0.29ab±0.04

Each value is mean±SD (n=3).
Mean with the same letter within a column is not significantly different at p<0.05.
