The ANR Redlosses project begins to bear fruit

Advances of Redlosses
The dataset of 714 samples was deposited on the INRAE ​​data portal and published in a data paper. A quantitative review of the spoilage literature and a first research article on the effect of lactate and protective atmosphere on spoilage in poultry and pork sausages were recently published.
redlosses

Context and challenges: The spoilage of meat products by the proliferation of bacteria and their metabolic activity leads to significant losses and waste. This is a major economic stake for the agro-food industries. Defects in appearance, texture, smell and flavor lead to non-compliance with quality criteria and cause loss of products. Spoilage, appearing at the end of the process or during storage, affects the entire production chain and impacts the sustainability label of the meat sector.
Results: Ten batches of pork and poultry sausages were produced by the two industrial partners of the project according to three lactate formulations, and packaged under three different atmospheres (air, oxygen-enriched atmosphere, oxygen-depleted atmosphere). Multivariate data was generated by all partners throughout storage. All of the datasets represented 714 samples, including the collection of data from sensory analysis, volatiloma, and bacterial communities by amplicon sequencing. These data were deposited on the INRAE1 data portal and published in a data paper2. The use of the data has started to bear fruit: a first PLS model allowed the selection of potentially altering and non-altering microbiotas; this model is currently undergoing experimental validation. A quantitative analysis of the spoilage literature3 and a first research article on the effect of lactate and modified atmosphere on spoilage in poultry and pork sausages4 were recently published.
Perspectives: Several other valuations are also underway: on the modeling of pH using a Bayesian approach, on the causal links between sensory, volatiloma and microbiota in poultry sausages, and finally on the effect of process on the microbial ecology and the sensory evolution of poultry and pork sausages.
