PREPARATION OF CONCENTRATES OF COLOURING AGENTS |
| 摘要 |
Concentrates of natural colouring agents such as carotene are prepared from organic media, particularly from palm oil, by a process in which the oil, together with a volatile solvent, is subjected to gel permeation chromatography. The concentrated colouring agent may then be used in food products such as margarine and ice cream. |
