| 摘要 |
The invention relates to a method for analysis of fat-soluble components, in particular fat-soluble dyes, from biological materials, in particular foods and feeds, having facilitated extraction of the fat-soluble components from the biological materials with use of suitable dilution solutions and of the extractability using pertinent organic solvents or organic solvent mixtures and also an enrichment and separation method, with subsequent digital evaluation and documentation. It is proposed to treat the biological materials first with a dilution medium which makes the fat-soluble components more readily extractable from the complex biological matrix and subsequently with at least one organic solvent which extracts the components; the substances extracted into the organic supernatant are subsequently chromatographically enriched and separated and then visually assessed and/or measured. |
