METHOD AND APPARATUS FOR quantitative determination of wax and wax-like substances in refined vegetable oil

摘要

1. A method for the quantitative determination of waxes and wax-like substances in refined vegetable oils, wherein the measuring cuvette is placed in a previously prepared sample of oil at a given initial temperature, measured optical transmittivity of the reference and the test oil sample by irradiating the samples and the concentration of wax compounds wherein that the measuring cell is placed hot vegetable oil sample produced simultaneously irradiating the sample and edited nenie its temperature, the sample was cooled from an initial temperature to complete solidification of the sample is continuously measured light flux passing through the sample, and a light flux scattered by the sample volume and the inner surface of the cell, is calculated depending on the temperature ratio of the transmitted and scattered light fluxes and the maximum this ratio at a given temperature cooling section samples based on previously obtained calibration curve of standard samples determined quantitatively wax content and wax-like substances in the test sample of vegetable masla.2. Process according to claim 1, characterized in that the sample is cooled from an initial temperature at a predetermined cooling rate of about 0,3 ° C / p.3. A method according to claim 1, characterized in that the measuring cell is placed the previously prepared oil sample at a predetermined initial temperature of about 120 ° C.4. Apparatus for the quantitative determination of the content of waxes and wax-like substances in refined vegetable oils, comprising a housing with a thermoelectric module as a device oh
