Solvent mixt. for extracting unwanted lipids anns - from skin consisting of acidified isobutanol with chelating agent

摘要

Solvent for simultaneously extracting lipides and related matls. such as pigments, natural proteic matls. and undesirable metallic ions, consists of lightly acidified isobutyl alcohol. Solvent is vigorously mixed with animal or fish extract at 66 degrees C and the mother liquor is separated. The process is repeated until the liquid is clear, and the residue evaporated. The solvent extracts these matls. without simultaneous dehydration of treated prod. The prod. is used for animal food, Pref. the solvent is mixed with mineral or organic acid (acetic) and may contain a chelating matl. such as a chlorophyll deriv. (Ca chlorophyllinate (I)), An example is 3 lisobutanol mixed with 5 ml acetic acid and 5g (I).
