Adria Normandie works in the field of health hazard control,
involving the following:
|
 |
Predictive microbiology: running challenge-tests
on various pathogenic bacteria (Listeria monocytogenes, Salmonella,
E.coli O157 H7, Bacillus cereus) and participating in the set-up
of a French database of predictive microbiology (SYM PREVIUS).
The tests are run on a food matrix in pilot manufacturing conditions.
They assess the incidence of processes (heat processing, for
instance), or of the preservation conditions, on the development
of pathogenic microorganisms.
|
|
The Durable-Life Date (DLD) validation through ageing
tests on food products stored in different cold chains (monitoring
of regulation flora) |
|
The set-up of a quality organisation such as HACCP
in a company |
| |
|
| The
Teams |
| A Microbiology Unit at the Research
and Development Department with 1 microbiological engineer and
2 research assistants; Laboratory of Microbiological and Physicochemical
Analysis (1 engineer and 8 technologists); Technological Assistance
Unit with one food technology engineer and one research officer;
Quality Department with one engineer (AFAQ auditor) and 2 project
leaders (training and consulting at companies) |
| |
|
| Equipments |
|
Microbiology: various equipment for microbial cultures,
microscopy, programmable double-boiler for heat resistance measurements,
spectrophotometers, refrigerated rooms, and so on |
|
- Technology Hall (500 square metres) with various
equipment for making convenience food: see the file on Technological
Innovation |
| |
|
| Methods |
|
Counting, non-selective and selective media, isolation
and identification of pathogen and spoilage microorganisms |
|
Counting of legally required flora |
|
Culture in model environments and on food matrixes |
|
Growth measurement (latency and generation time)
and measurement of optimal growth parameters, measurement of heat
resistance (TDT tubes and capillary tubes) |
|
Physical and chemical product control (pH, Aw, composition,
and so on) |
|
Training in hygiene |
|
Audit and hygiene assessment of the site |
|
Analysis of critical points |
| |
|
| Application Examples |
|
Development of Escherichia coli 0157H7 in atmosphere-controlled
packs of lettuce |
|
Optimisation of the challenge-test methodology with
Listeria monocytogenes in food products |
|
Incidence of heating and cooling kinetics on the
heat resistance of Bacillus cereus spores |
|
Incidence of modified atmosphere on the DLD of convenience
food |
|
Set up of the HACCP system in a meat-processing
company |
