RAPID DIAGNOSTIC METHOD OF NATURALITY OF WINE PRODUCTS Russian patent published in 2010 - IPC G01N33/14 

FIELD: measurement equipment.

SUBSTANCE: there prepared is biological test system by mixing 0.1% water solution of mixture of the following amino acids: valine, lysine, asparagine, glutaminic acid, tyrosine, tryptophane and serine, which are taken in equal proportions, 0.5% water solution of dopamine neuromediator, 1 mM of water concentration of nucleotide DNA bases - guanine, cytosine, thymine, adenine, which are taken in equal proportions, and 25% water solution of magnesium sulphate. Components of the test system are used at the following ratio, wt %: mixture of amino acids - 38-42, dopamine neuromediator - 8-12, nucleotide DNA bases - 8-12, magnesium sulphate - 38-42. On microscope glass there put is 0.02-0.03 ml of biological test system in the form of a track which is enveloped along the periphery with a strap of the tested product, exposed, dried and the obtained specimen is tested in polarisation light with quartz compensator, and as per oriented sub-parallel aggregates and structural elements available in biological test system there estimated is naturality of the tested specimen.

EFFECT: invention increases fidelity of information and reduces the time required for analysis.
