Obesity is the leading metabolic disease in industrialized countries and is closely associated with coronary heart disease, hypertension, diabetes, and cancer. The objective of this study was to evaluate the anti-adipogenic effects of two roasted coffee beans, Vietnam robusta (VR) and Ethiopia Mocha Sidamo G2 (ES), as well as fermented coffee beans with Monascus ruber (MR) mycelium on differentiation of 3T3-L1 preadipocytes. Treatments with 1,000 ${\mu}g/mL$ of hot water extract from coffee beans significantly reduced intracellular lipid accumulation. In addition, VR more effectively inhibited transcription factors such as $PPAR{\gamma}$, $C/EBP{\alpha}$, FAS, and aP2 compared to ES. Further, ES fermented with MR showed more effective anti-adipogenic activity than non-fermented ES. These results suggest that VR and ES inhibit adipocyte differentiation which may contribute to their anti-adipogenic properties.

Three mushroom mycelia, Ganoderma lucidum, Hericium erinaceum, and Phellinus linteus, were separately diluted with the natural culture media Acanthopanax senticosus. Solid-state fermentation was used to produce three different A. senticosus-fermented mushroom mycelium groups: G. lucidum mycelia, H. erinaceum mycelia, and P. linteus mycelia. The resulting mycelia were analyzed to assess their efficacies as health functional foods. Optimized fermentation conditions were determined by considering the density and growth speed of mycelia in each A. senticosus-fermented mushroom mycelium group. The cultured mushroom mycelia under the optimized conditions were extracted using water and 70% ethanol. Extraction was followed by filtration, concentration and freeze-drying to produce extract powder of A. senticosus-fermented mushroom mycelia: Water extracts (FM-5111, FM-5121, and FM-5131) and 70% ethanol extracts (FM-5112, FM-5122, and FM-5132). Analysis of extract powder of A. senticosus-fermented mushroom mycelia was performed using the maker compounds eleutheroside B and eleutheroside E. Analysis of ${\beta}$-glucan contents was performed by enzymatic procedures.
