1. A method for measuring the gerontological value ofbio-active substances and compositions, mainly foodstuffs and cosmetics, said method including the steps of: determining a melting temperature of an examined supramolecular structure of samples taken from a series of products to be studied; specifying a standard temperature which is less than a minimum melting temperature of the examined supramolecular structure of samples taken from the studied series of products; determining a value of the specific Gibbs function of formation of the examined supramolecular structure for samples taken from the studied series of products at said standard temperature; selecting, by a minimum value of the specific Gibbs function of formation of the examined supramolecular structure, a standard sample for which a gerontological value indicator is assumed to be unity; determining, for an examined sample, a value of-the specific Gibbs function of formation of the examined supramolecular structure at the standard temperature; comparing the values of the specific Gibbs function of formation of the examined supramolecular structure of the standard sample and the examined sample by defining the relation between said values, and judging the gerontological value of the examined sample from the direct proportionality to the value of said relation, 2. A method as set forth in claim 1, wherein said standard temperature is a temperature which is from 2 to 6 degrees lower than the minimum melting temperature of the examined supramolecular structure of samples taken from the studied series of products. 3. A method as set forth in claim I or claim 2, wherein said melting temperature of the examined supramolecular structure is a melting temperature of lipid and/or protein, and/or carbohydrate, and/or nucleotide supramolecular structures of the samples for which the gerontological value is being assessed. 4. A method as set forth, in claim 1, or claim 2, or claim 3, wherein said determining, for an examined sample, of a value of the specific Gibbs function of formation of the examined supramolecular structure at the standard temperature is performed using known calibrating plots of functional relation , through measuring concentration Ci of water in plant and animal tissues, or in supramolecular structures thereof. |
