Abstract

The objective of the project is to standardize the production of reduced sodium Prato cheese with bioactive properties, as well as to evaluate the bioaccessibility of the biopeptides formed during ripening. The project will be divided into two stages. First, the effect of the addition of the adjunct culture (Lactobacillus helveticus LH-B02), salt content, and ripening time on the antihypertensive potential, and the peptide profile will be assessed using a 2x2x6 factorial experimental design in completely randomized blocks with three replicates. The peptide profile will be analyzed by Matrix-Assisted Ionization and Laser Desorption Mass Spectrometry (MALDI-ToF MS) and the discrimination of cheeses according to their peptide profile will be performed by chemometrics using principal component analysis. Then, cheeses with higher bioactivity potential will be evaluated for peptides bioaccessibility and for the effect of these compounds on gut microbiota. A dynamic in vitro colonic digestion model (SEMH) composed by 5 double-jacketed vessels simulating the stomach, the duodenum and the ascending, transverse and descending colon, under controlled conditions of pH, residence time and temperature will be used for the simulation of the passage through the gastrointestinal tract. During the simulation of the passage through the gastrointestinal tract, samples will be taken from each vessel for the evaluation of the peptide profile (MALDI-ToF MS) and modulation of the microbial ecosystem.
