TL;DR
This study tracks how the cheese Crema de Chiapas changes during ripening, focusing on its chemical and microbial shifts.
Contribution
The study reveals how microbial diversity and physicochemical properties evolve during cheese ripening using metagenomic and qPCR analyses.
Findings
Protein content influenced sample differentiation more than other properties during ripening.
Microbial diversity shifted with ripening, showing reduced bacterial, fungal, and yeast populations.
Potentially pathogenic microorganisms were not detected at biologically relevant levels.
Abstract
The dynamic changes in the physicochemical, microbiological, and metagenomic profiles of Crema de Chiapas cheese were evaluated across three ripening stages (2, 29, and 58 days). Although the main physicochemical properties —including fat content— remained remarkably stable, salt and protein levels showed noticeable variation throughout ripening. Protein content had the strongest influence on sample differentiation across ripening stages in unsupervised multivariate models, enabling the clustering of microbial diversity according to maturation time. A clear shift in microbial diversity was detected, marked by a reduction in bacterial genera and a concurrent decline in fungal and yeast populations as ripening advanced. The predominant bacterial genera throughout ripening were Streptococcus, Lactobacillus, and Lactococcus. While Streptococcus and Lactobacillus increased over time,…
