In particular when extracting tea, coffee, bonito or dried shiitake the residue from the dimethyl ether extraction may be extracted with water which is then evaporated to produce a further extract (i.e. as in "instant" tea or coffee) to which is added at least a portion of the initial dimethyl ether extract, which may have had only part of the dimethyl ether and water removed, finally removing any remaining dimethyl ether or water. Preferred foods and flavors include pepper, nutmeg, turmeric, laurel, anise, thyme, coffee, tea, dried bonito, dried shiitake, lemon, lime, citran, roast chicken, roast beef, roast pork, egg yolk or a flaver belonging to Rosaceae, Oleaceae, or Compositae. |
