A three days course on Agro-resources Dry Biorefinery in Montpellier

UMR IATE (Agropolymer Engineering and Emerging Technologies)

A large part of our agro-resources (mainly cereal grains) are transformed into food products using dry fractionation methods which are based on the traditional know-how of a number of actors. However, this food-chain has regularly to face with annual variation of the raw matter due to evolution of the genetic selection and changes in the climatic and farming conditions. Moreover, it is also expected to produce more healthy products with reduce costs and loss, but maintaining safety and sensory aspects. It has also to challenge with the demand of innovation. As lands devoted to agriculture tends to decrease whereas consumer demand enlarges both food and non-food uses, it is also more and more important to refine all of the agro-resource parts.

This course presents the new stakes in dry refinery of both types of agro-resources (cereal grains and ligno-cellulosic material) and the way to improve our knowledge to control or develop products adapted to consumer needs.

Presentation of the biochemical composition and structure of different types of agro-resources according to distinct uses will be presented and linked to the possible associated constraints or benefits for food and non-food uses. Methods to better analyze their inner biochemical composition and structure and ways to study their behavior along dry-fractionation are developed.

Methods to characterize their mechanical properties from nano- to micro-scale are presented and link with their behavior along process. Distinct grinding devices and principles are detailed and illustrated thanks to the different equipment available in our fractionation platform.

Different principles for the physical characterization and separation of the divided raw matter are developed and illustrated through presentation of original pilot devices located in UMR IATE and through experimentation.

Approach developed to integrate data and to model fractionation behavior is also shortly presented.

This course is limited to 10 persons and is delivered in English every year around April-May. This course involved 7 different researchers for lessons and 4 researchers and technician for practical experiments. It is first proposed to students of the doctoral school SPSA in Montpellier but is opened to doctoral or post-doctoral students from any country.

First session in 2015 was achieved from May 27th (9:30) to 29th (17:00) and welcomed 8 students with 8 distinct nationalities and encountered a real success.
