The Food Pole

Platforms for characterization and transformation of food and raw materials:

✔️ The Dairy Technology Research Platform: the "Milk platform"/ La Plateforme Lait (PFL):

The PFL platform, as a component of the CALIS Food Pole, provides research collaborations, service offerings, and training to all academic and industrial partners:

▶️ Milk transformation methods:

• Thermization and UHT sterilization of milk
• Preparation of milk fractions
• Cheese making and ultra-fresh products
• Preparation of concentrates and powders
• Valorization of milk by-products

▶️ Specific technological processes:

• Membrane separation: microfiltration, ultrafiltration, nanofiltration and reverse osmosis
• Cheese technology
• Concentration
• Drying

✔️ The PLANET Platform:

▶️ The PLANET platform is a specialized component of the CALIS Food Pole.

▶️ The missions of the PLANET platform are:

• to participate in research programs;
• to contribute to the development of methods and processes for the valorization of plant raw materials for various application areas (food, biomaterials and bioenergy);
• to develop scientific collaborations with external partners;
• to support training and knowledge dissemination.

✔️ Platforms of the PROBE Research Infrastructure:

The distributed PROBE infrastructure, as a component of the CALIS Food Pole, includes 4 platforms offering techniques and methods adapted to the chemical, physico-chemical, organoleptic and structural characterization of bio-based raw materials and processed products. This PROBE characterization offer is distinguished by its multi-modal and multi-scale aspect, ranging from molecular scales to those of the plant or organism. Open to academic institutions and industries, the service offer is specialized on food matrices, but it also includes requests in the fields of SEA and HEALTH.

✔️ The Technical platform for in vitro digestive environment simulation (DIGEST-IV):

▶️ The DIGEST-IV platform provides specialized services in the field of in vitro digestion within the CALIS Food Cluster.

▶️ The service offer of the DIGEST-IV platform concerns the screening and development of formulated products as well as the study of fundamental mechanisms with simulation of dynamic digestive systems modulated by physiological, pathological or dietary conditions.

▶️ More precisely, DIGEST-IV offers a service based on the use of static digestion systems (INFOGEST protocol, colonic fermentation in batch) and dynamic digestion to simulate the main gastrointestinal functions - digestive process in the tract and colon - for human and monogastric animal models (pig, piglet, dog):

▶️ Specific analyses and models offered as a service or collaboration:

• Micro-GC: micro-chromatography (with thermal conductivity detector: TCD), HPLC (with diode ultraviolet detectors: DAD, refractometer), electrophoresis
• Gastrointestinal digestion models: TIM1: TNO1 Intestinal Model / ESIN: Engineered Stomach and Small Intestine
• Simulation of colonic fermentation by ARCOL bioreactors
• Aerobic / anaerobic, cultural, molecular microbiology
