Hypocholesterolemic properties of cape gooseberry

Chemical composition and some physico-chemical parameters of the Physalis peruviana fruit juice were investigated. The antioxidative potential of fruit juice was assessed by means of bleaching of the stable 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. The yield of juice is extremely high and the juice is rich sources of sugars as well as water- and fat-soluble bioactives. Goldenberry pomace (seeds and skins) represent the waste obtained during juice processing (ca. 27.4% of fruit weight). In the present contribution, the potential of goldenberry pomace for use as a substrate for the production of edible oil was evaluated. Toward developing goldenberry as a commercial crop, the results provide important data for the industrial application of goldenberry. The study also covers the chemical composition and some fractional properties of pomace oil including fatty acid profile and other fat-soluble bioactives (i.e. sterols, tocopherols and phenolics). Pomace oil was tested for its radical scavenging activity toward the stable 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and their oxidative stability.
