説明

The aim of the present study was to investigate the stability of binding mutagenic tryptophan pyrolysates such as Trp-P1 and Trp-P2 to Lactobacillus casei subsp. casei R-52 cells. Stability was estimated by quantifying the amount of Trp-P1 or Trp-P2 dissociated from R-52 cells bound with Trp-P1 or Trp-P2 under the presence of trypsin or bile acid, or various pH conditions (pH2.0-8.0). The addition of trypsin to the assay system did not affect the dissociation of Trp-P1 or Trp-P2 from the cells, whereas the addition of oxgall to the system caused obvious dissociation. Under the presence of 0.3% oxgall, the dissociation rates of Trp-P1 and Trp-P2 were nearly 50% and 85%, respectively.
