(A) All metabolites measured. (B) Metabolites with significant difference in average concentrations among the processes. Error bars indicate the standard error. *, significant difference (P < 0.05) with Bonferroni correction for multiple testing. I, initial raw vegetable group (n = 8); P, pretreatment group (n = 8); S, salt stock preparation group (n = 8). Ala, alanine; Arg, arginine; Asn, asparagine; Asp, aspartic acid; Glu, glutamic acid; Gln, glutamine; Gly, glycine; His, histidine; Ile, isoleucine; Leu, leucine; Lys, lysine; Met, methionine; Phe, phenylalanine; Pro, proline; Ser, serine; Thr, threonine; Trp, tryptophan; Tyr, tyrosine; Val, valine; 2KG, 2-ketoglutaric acid; Cit, citric acid; Lac, lactic acid; Pyr, pyruvic acid; Suc, succinic acid. P-values for metabolites with significant difference were as followed: *a, 0.001; *b, 0.001; *c, 0.0002; *d, 0.002; *e, 0.0002; *f, 0.010; *g, 0.007; *h, 0.010; *j, 0.010; *k, 0.0002; *m, 0.001; *n, 0.0002; *o, 0.001; *q, 0.0002; *r, 0.0002; *t, 0.005.
