Abstract
Provided herein is a method for extraction of crude coffee oil (CCO) from spent coffee ground (SCG) using Mechanical Hydraulic Press Machine. The extraction includes a preliminary step of reducing moisture content of the raw material followed by mechanical extraction of the spent coffee ground to obtain crude coffee oil. Also provided herein is a chemical-free method for purification of crude coffee oil to obtain pure coffee oil.
Claims11
A method for extraction of Crude Coffee Oil (CCO) from Spent Coffee Ground (SCG) using a Mechanical Hydraulic Press Machine, the method comprising the steps of:
- a. reducing moisture content of the raw material to obtain a SCG raw material having 19-26% moisture content;
- and
- b. extracting the SCG raw material obtained at the end of step (a) to produce crude coffee oil;
- wherein extraction of the SCG raw material involves compression of SCG raw material obtained at the end of step (a) at a pressure of about 400-600 bars and at a temperature of 36-39° C.
A method for production of pure coffee oil (PCO) from spent coffee ground (SCG) the method comprising the steps of:
- a. reducing moisture content of the raw material to obtain a SCG raw material having 19-26% moisture content;
- b. extracting the SCG raw material obtained at the end of step (a) to produce Crude Coffee Oil (CCO);
- and
- c. purifying the crude coffee oil (CCO) to obtain pure coffee oil (PCO);
- wherein extraction of the SCG raw material involves compression of SCG raw material obtained at the end of step (a) at a pressure of about 400-600 bars and at a temperature of 36-39° C.
