Paper presented at the 52nd CFCS Annual Meeting, Guadeloupe, July 10-16, 2016
The second sub session was about FOOD – ELABORATION OF FOOD. Processed products by fermentation are also of interest like cheese, yoghourt, and sauerkraut. Fermentation could be spontaneous or driven. To prepare products with specific properties, the fermentation parameters have to be controlled, like temperature, to optimize the properties. An example of papaya fruit and papaya leaves fermentation was presented. Organs of interest of Caribbean plant diversity have to be prospected as substrates to elaborate fermented products with checked and listed functional properties. The last sub session dealt: GREEN CHEMISTRY. We had a presentation about utilizations of waste biomass for the production of chemicals and fuels. The potential is important but precise routes have to be determined to produce targeted chemicals from renewable abundant carbon sources, like lignocellulosic biomass. Design of new catalyst systems is required for biomass conversion in an environmentally friendly and economical route. Aqueous Phase Processing (APP) are tested. Furfural conversion in furanone with a 96% yield is quite promising. Furanone has great marketability as it is used in the pharmaceutical industry as an appetite depressant and an immunosuppressive agent, and it is also utilized as a food flavoring agent. The second speaker present results of an interdisciplinary research program in renewable energy production, which aimed at identifying the agroenvironmental, economic and industrial conditions for producing electricity from energy cane in Guadeloupe. Energy cane strains were selected. The introduction of such bioenergy systems under existing conditions and current agricultural models is still rather uncertain and requires achieving several sustainable goals. In order to build new sustainable energy systems, assessment of the conditions for a sustainable and profitable biomass supply is a critical step prior to industrial investment. The third presentation was about pectin. Pectin is one of commercially interesting molecules frequently used as, functional agents in food, cosmetics and drugs making. Common sources of functional molecules are fractions of fruit and vegetable handled in some places of food chains like processing plants. The crop diversity is to be explored. Extraction methods operating in an environmentally friendly and economical route are researched. The last presentation was about an inventory of bioresources products and materials for buildings available on the island wood, paper, fibers, algae, lignocellulosic materials. Potential products and building materials appropriate to be developed, indicating the necessary conditions so required. The history of some failed experiences could be visited in order progress faster. This session, allowed addressing the key questions linked to the contribution of the innovative technologies and the green chemistry in the food and non-food valuation of the tropical bioresources met in the Caribbean. The session pointed out quite particularly, the conditions required to create ad hoc value chains, in the context of the small island economies. This topic constituted a major prerequisite to strengthen during the next congresses, to pursue the construction of a technological sector of the project for a Caribbean bioeconomy.
