  1. Proteins were classified by function according to the Panther (www.pantherdb.org/) online program.All of the proteins are eukaryotic from the species Rattus norvegicus. All of the proteins are overrepresented in the saliva of animals without LAB persistence. Only oxidations were searched and were abbreviated as follows: O/OH: Oxidation/Hydroxylation or diO/OH: dihydroxylation. Empty cells indicate no oxidations. Differences in the salivary relative protein levels of animals with and without LAB cheese were compared by ANOVA tests (FDR-adjusted p value and q-value). Proteins with a qvalue <0.05 (p value <0.01) were considered significantly different.
