  A process for extraction of a peptide from a reaction mixture resulting from a peptide coupling reaction, the reaction mixture containing the peptide and a polar aprotic solvent selected from the group consisting of N,N-dimethylformamide, N,N-dimethylacetamide and N-methyl-2-pyrrolidone, whereby the process includes a step a) and a step b): step a) including the addition of a component a1) and a component a2), whereby component a1) is 2-methyltetrahydrofuran and component a2) is water, to the reaction mixture, so that a biphasic system with an organic layer and an aqueous layer is obtained; step b) including the subsequent separation of the organic layer containing the peptide from the aqueous layer. In an embodiment, a combination of 2-methyltetrahydrofuran and an organic solvent 1 selected from the group consisting of n-heptane, toluene, ethylacetate, isopropylacetate, acetonitrile and tetrahydrofuran is used for the process for extraction. The extraction step is preferably used in a process for preparation of a peptide in liquid phase.

  Described herein is a peptide with an amino acid sequence comprising a Leu-Leu moiety. Also described is a composition having a mixture of such peptides, and foods and beverages containing such compositions including, for example, roast and ground coffee, coffee brew, coffee creamer, and tea. The addition of one or more of these peptide(s) to coffee brews made from instant coffee, liquid coffee concentrate, or decaf coffee demonstrates that these peptides improve the taste profile of such coffee brews.
