    Polymer membrane, obtaining procedure, uses thereof and detection method of furfural and/or 5-hydroxymethylfurfural. The present invention relates to a polymeric membrane of acrylate and/or methacrylate type comprising aniline, unsubstituted in the amino group, or a derivative thereof, to the process for obtaining the membrane, and to the uses given thereto. . The present invention relates to the detection of compounds that mark the freshness of foods, such as furfural and 5-hydroxymethylfurfural (5-hmf). More specifically, the present invention describes a method for detecting furfural and/or 5-hmf in a sample by detecting a color change, in a polymer membrane comprising aniline.

    present in a food simulant, water: ethanol (94.6: 5.4;% v / v). The maximum wavelength at 537 nm is taken. DETAILED EXHIBITION OF THE INVENTION
    As mentioned above, one aspect of the present invention relates to a polymeric membrane comprising aniline monomers and acrylate or methacrylate monomers with ethylenically unsaturated groups.
    10 The term "ethylenically unsaturated group" is used here in a broad sense and is intended to encompass any of the groups containing a group -C = C-.
    Examples of methacrylate or acrylate monomers are: 2-hydroxyethyl 2-methylprop-2-enoate (HEMA) or 2- (2-methyl-acryloyloxy) ethyl 2-methyl acrylate (EDMA). Particularly the aniline derivative is 4-vinylaniline.
    Preferably, the thickness of the membrane is between 0.5 mm and 1.2 mm.
    20 Preferably the sample is a food sample.
    In the process for obtaining the membrane of the invention a polymerization initiating compound is used. In the present invention the "polymerization initiating compound" refers to a chemical compound that initiates the polymerization reaction
    25 by radio route through the use of thermal energy or with UV light. Examples of suitable radical initiators include, but are not limited to, 2,2'-azobis (2,4-dimethylpentanenitrile), 2,2'-azobis (2-methylpropanonitrile), 2,2'-azobis (2-methylbutanenitrile), peroxides such as benzoyl peroxide, and the like. Preferably the polymerization initiator is 2.2 azobis- (2,4-dimethylvaleronitrile) (ABDV).
    In addition, in the process for obtaining the membrane of the invention, once the solutions of the different monomers have been prepared, the mixture is deposited on a support. Preferably the support is two glass plates and the polymer is deposited between them.
