Adsorbent and flavor stabilizer for coffee liquor using supercritical fluid extraction residual of roasted and ground coffee beans

摘要

PURPOSE:To enable effective utilization of the subject residue while improving the stability of the residue with time, etc., by extracting roasted and crushed coffee beans with a supercritical fluid and using the extraction residue as an activated carbon material for industrial use or as a food additive such as an additive to instant coffee. CONSTITUTION:Roasted and crushed coffee beans are extracted with a supercritical fluid. The extraction residue is used as an activated carbon material for industrial use or as a food additive to be added to an instant coffee or liquid coffee (including concentrated coffee) as an agent for enhancing the taste and flavor of coffee. The above residue can be effectively utilized as an inexpensive agent having excellent decoloring and deodorizing effect and improved stability with time.
