Effect of walnut peptide‐ZnO nanocomposites on the colon adhesion behavior of Lactobacillus rhamnosus LRa05
Abstract When the nanoparticles (NPs) in food contact materials are exposed, they may be ingested with the food matrix, resulting in unknown impacts. Here, the biological response of the nanocomposites of nano zinc oxide (nZnO) and walnut protein‐derived peptides (i.e., PW5, WN5, AE6, and WE7) on th...

| description | Abstract When the nanoparticles (NPs) in food contact materials are exposed, they may be ingested with the food matrix, resulting in unknown impacts. Here, the biological response of the nanocomposites of nano zinc oxide (nZnO) and walnut protein‐derived peptides (i.e., PW5, WN5, AE6, and WE7) on the Lactobacillus rhamnosus LRa05 growth and adhesion was studied. In an in vitro mouse intestinal adhesion model, we first spotted that the probiotics LRa05 primarily adhered to and colonized the colonic segment. nZnO effectively inhibited the growth and adhesion properties of LRa05 at high concentrations (≥ 1000 μg/mL). Fortunately, when compared to the individual nZnO, the nZnO‐walnut‐derived peptides nanocomposites significantly increased the growth of LRa05. It was found that the alterations in the adhesion ability of LRa05 after treatment with various substances (nZnO and nanocomposites of nZnO‐walnut peptides) were related to the auto‐aggregating property on the LRa05 surface. These results shed light on the effect of food matrices on the safety of nanomaterials in food, and they may have far‐reaching implications for the use of nanomaterials in the food industry. |
