Abstract

We investigated the anti-obesity and anti-hyperlipidemic effects of extracts of two roasted coffee beans (Vietnam robusta and Ethiopia mocha sidamo G2) and fermented coffee beans with Monascus rubber mycelium (MR) by solid-state culture. C57B/L6 mice were divided into seven groups: normal diet (ND) group, high fat diet (HFD) group, and HFD groups with hot water extracts from Vietnam robusta coffee beans (HFD-VR), MR-fermented Vietnam robusta coffee beans (HFD-VR-MR), MR-fermented Vietnam robusta coffee beans with 10% brown rice (HFD-VRMR- BR10), Ethiopia mocha sidamo G2 coffee beans (HFD-ES), and MR-fermented Ethiopia mocha sidamo G2 coffee beans (HFD-ES-MR). After 6 weeks, body weight gain and food efficiency ratio were higher in the HFD group, but significantly reduced in the coffee extracts-fed groups. The HFD-ES-MR group showed greater body weight reduction than the HFD-ES group. The serum triglyceride, total cholesterol, and LDL-cholesterol levels as well as the atherogenic index and cardiac risk factor all tended to decrease in groups fed Vietnam robusta coffee extracts compared to the HFD group. These results suggest that Vietnam robusta and Ethiopia mocha sidamo G2 may be used to make functional coffee beverages with anti-obesity and anti-hyperlipidemic activities.
