abstract |
The invention relates to a method for the isolation of contents made from organic material, comprising the following method steps: (a) freeze-drying the organic material, (b) extraction of the contents with a polar solvent or solvent mixture (A) and an organic solvent or solvent mixture (B), whereby the extracts from the extractions with (A) and (B) can form one phase, (c) combination of extracts (A) and (B) to give one phase and (d) carrying out an esterification/transesterification in the non-polar phase with an alcohol. The esterification/transesterification is carried out in the presence of a liquid acid. The method is a high-throughput method. |
