    Abstract: A solid material is treated, the chemical structure of which defines reactive protogenic hydrophillic functions accessible to gases, by applying at least one gas stream (3) onto at least one microdispersion (5) of at least one grafting reagent RX produced on the solid material, R being a hydrophobic group, X being chosen so that HX is volatile under normal conditions, R and X being chosen so that the reaction of RX on the hydrophillic functions produces covalent grafting of the hydrophobic group R with formation of the compound HX, it being possible for the reaction to be carried out in a solid/gas heterogeneous medium on all the reactive hydrophillic functions accessible to gases and only on these. The invention extends to the hydrophobic solid material obtained, and is applicable to the obtaining of natural or artificial fibrous or inorganic structures impermeable to water and to aqueous solutions and/or absorbing fats.

    Abstract: A biodegradable particulate vector for transporting biologically active molecules is prepared containing a nucleus for containing a biologically active molecule, a first layer of fatty acid compounds covalently bonded to the nucleus and a second layer of phospholipids hydrophobically bonded to the first layer. The nucleus is between 10 nm and 10 .mu.m in size and is formed of a cross-linked polysaccharide or oligosaccharide matrix onto which ionic ligands are uniformly grafted. The cross-linked polysaccharide may be dextran, cellulose or starch cross-linked with epichlorohydrin. The ligand may be an acidic compound selected from succinic acid, phosphoric acid, citric acid, glycine, alanine, glutamic acid and aspartic acid, or a basic compound such as choline, hydroxycholine, 2-(dimethylamino)ethanol or 2-(dimethylamino)ethylamine fastened onto the matrix via the acidic compound. The polysaccharide or oligosaccharide may be co-cross-linked with a protein such as keratin/collagen or elastase. The vector may be prepared by reacting succinic acid monochloride in aqueous solution with a cross-linked polysaccharide or oligosaccharide matrix to graft succinic acid onto the matrix to form the nucleus, grinding the nucleus to a size between 10 nm and 10 .mu.m, drying the ground nucleus, coupling fatty acid compounds to the nucleus to form a first layer and hydrophobically bonding phospholipids to the first layer to form a second layer. The succinic acid monochloride is preferably prepared by reacting succinic acid dichloride with free succinic acid to form pure crystalline succinic acid monochloride.

    Abstract: The invention relates to a process for preparing a food solid, in which is prepared a mixture: of an amount of a flour comprising at least one polysaccharide, named heteromannan, chosen from the group formed from glucomannans and galactomannans, and of an amount of an aqueous liquid composition, characterized in that said heteromannan is in an amount such that the ratio of the mass of said heteromannan in the mixture to the mass of said aqueous liquid composition in the mixture is between 5 % and 35%, and in that the mixture is prepared by vigorous stirring, via which a substantially homogeneous dispersion is formed, named pourable dispersion, of the flour in the aqueous liquid composition, and having a dynamic viscosity of less than 100 Pa·s, said pourable dispersion spontaneously changing to form an aqueous cohesive solid which is substantially free of free aqueous liquid composition and which has a dynamic viscosity greater than the dynamic viscosity of said pourable dispersion, and then a step of maturation of the aqueous cohesive solid and of hardening of the aqueous cohesive solid is performed so as to form the food solid, the formed food solid being non-adhesive and non-coalescent; and in that, since said heteromannan comprises at least one glucomannan, said heteromannan is not subjected to any treatment with an alkaline agent, notably to any treatment with calcium hydroxide (Ca(OH)2) or with sodium carbonate.
