K means clustering analysis of differential metabolites

DOI: 10.7717/peerj.14458/supp-4

The present study identified 53 metabolites during Fl that showed significant changes from TA to TB and TB to TC after SPD treatment

DOI: 10.7717/peerj.14458/supp-5

7 vitamins and 11 saccharides and alcohols showing significant changes between the TA and TC stages by SPD treatment were identified

DOI: 10.7717/peerj.14458/supp-6

14 out of 372 differential metabolites changed more than ten times at the different stages of FI treated with SPD, but had no significant changes treated with water
