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.
