摘要:
According to the present invention, it has been found that long-chain alkyl cyclic acetals made from sugars can be obtained by a method that comprises the steps consisting of: - dehydrating a hexitol in a mono-anhydro-hexitol substrate; - reacting the obtained mono-anhydro-hexitol substrate with an alkyl aldehyde reagent containing between 5 and 18 carbon atoms, by means of an acetalisation reaction with a substrate/reagent ratio of between 5:1 and 1:1, or with a derivative of an alkyl aldehyde reagent containing between 5 and 18 carbon atoms, via a trans-acetalisation reaction with a substrate/reagent ratio of between 1:1 and 1:3, in the presence of an acid catalyst and in an environment that is free of solvent or that consists of a non-aqueous polar solvent; - recovering the long-chain alkyl acetal hexitane from the obtained mixture.
摘要:
The invention relates to a composition of isomers of mono-alkyl ethers of monoanhydro-hexitol having an alkyl ether radical (OR) at C-3, C-5 or C-6 of the monoanhydro-hexitol, in which the alkyl group (R) is a linear or branched, cyclic or non-cyclic hydrocarbon group comprising between 4 and 18 carbon atoms. The invention also relates to the method for producing such a composition, as well as to the use thereof as a non-ionic surfactant, an emulsifier, a lubricant, an antimicrobial agent or a dispersing agent.

An extended shelf-life proteinaceous meat analogue comprises at least one inclusion included in a matrix which comprises vegetable proteins including at least wheat gluten and a plasticizer. Said proteinaceous meat analogue has a water content of less than 20% (w/w) and a torque value at 10 mn of at least 6 gram meter (g*m), as determined by a test A. A method for obtaining an extended shelf-life proteinaceous meat analogue comprises the step of (i) mixing vegetable proteins, including at least vital wheat gluten, and a plasticizer for obtaining a dough, (ii) shaping said dough by at least cutting the dough in dough pieces and agglomerating said dough pieces with at least one inclusion to obtain an agglomerate, and (iii) heating said agglomerate, wherein said extended shelf-life proteinaceous meat analogue has a water content of less than 20% (w/w). A food stuff comprises said extended shelf-life proteinaceous meat analogue and the method for obtaining said foodstuff.
