Obesity, the leading metabolic disease, is a prevalent health problem in industrialized countries and is closely associated with coronary heart disease, hypertension, diabetes, and even cancer. In this study, we investigated the effects of dip-sauce for meat containing Garcinia cambogia extract (GC) on the lipid accumulation and body weight reduction in rats fed highfat diet for three months. Eighteen Sprague Dawley male rats of five-week-old were randomly assigned to one of three groups; normal chew diet (NCD) group, high-fat diet plus GC-noncontaining dip-sauce (HFD) group, and HFD plus GCcontaining dip-sauce (HFD+GC) group. Co-administration of GC-containing dip-sauce (5 g/kg body weight/day) with HFD significantly attenuated cumulative body weight gain, compared with NCD or HFD groups. Both epididymal and perirenal fat pad weights in the HFD plus GC group were significantly lower than those of HFD or NCD groups. Administration of GC-containing dip-sauce also resulted in significant reduction in the serum levels of total cholesterol, total lipid, and triglyceride, compared with NCD or HFD groups. Thus, GC-containing dip-sauce confers beneficial effects to pathological states associated with metabolic disorder via its anti-obesity and lipid lowering properties.

For development of premium sauce, fermented sauces containing ferment (with wheat flour and soybean) and extract(s) of Styela clava (Korean name: miduduk) tunic and/or mulberry leaves and/or onion were prepared, and their angiotensin converting enzyme (ACE) inhibitory and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities were evaluated. All sauces containing extract(s) showed increased ACE inhibitory and DPPH radical scavenging activities. Especially, sauces containing extracts of mulberry leaves and onion showed superior activities, with 26.92% and 40.66% relatively increased ACE inhibitory and DPPH radical scavenging activities, respectively, compared to control (no extract was added). These results suggest that extracts of mulberry leaves and onion could improve antihypertensive and antioxidant activities of fermented sauce.
