BACKGROUND We studied the antioxidant effects of fresh juice and peel extract of Citrus aurantifolia (Christm). METHODS Low density lipoprotein (LDL) was separated from one hypercholesterolemic human serum by modified Bronzert and Brewer procedure. Oxidation of LDL was measured at 234 nm against 0, 5, 10, 20, 25, 30 and 40 μl of fresh lime juice and 0, 5, 10, 15 and 20 μl of peel polyphenolic...

Zinc oxide (ZnO) synthesized with natural reductants has attracted the attention of researchers because it is environmentally friendly and non-toxic. In this study, ZnO was prepared using Sandoricum koetjape (S. koetjape) peel extract. An aqueous extract S. used as biological reduction agent for synthesis from zinc nitrate hexahydrate. The powder obtained annealed at different temperatures i.e,...

Production of intracellular β-xylosidase was studied in cultures of Penicillium janthinellum grown on citrus fruit waste supplemented cultivation media. Both dried orange peel and sweet lime peel could induce the production of this enzyme. The working strain showed a pronounced optimum pH and temperature for β-xylosidase production at 6.0 and 27 °C, respectively. The enzyme production was found...

Sweet corn has a higher moisture content, making it challenging to store for longer. The edible coating acts as primary packaging. samples were blanched in hot water at 90°C 90 s initially and coated with olive oil concentration 0%–100% 60–300 temperatures of 40–60°C, which makes the kernels acceptable even after 7 days comparison 4 untreated samples. water-blanched sweet increased length, widt...

The objective of this study was to identify the major antioxidative components present in the peel of rambutan (Nephelium lappaceum), mangosteen (Garcinia mangostana) and langsat (Lansium domesticum). The identification and quantification of the major antioxidative components were performed using high performance liquid chromatography at 254 nm. The results showed that ellagic acid and corilagi...

This study reports in vitro lipophilic antioxidant, inhibition of α-amylase and antibacterial activities of extracts of peel and pulp of citrus samples from Aceh, Indonesia. HPLC (high-performance liquid chromatography), phytochemical, and FTIR (fourier transform infrared) analysis detected carotenoids, flavonoids, phenolic acids and terpenoids, contributing to the biological potencies. Most pe...

The main objective of the present study was to investigate the effect of solvent type and ratio as well as the extraction techniques (i.e. supercritical fluid extraction (SFE) and conventional solvent extraction) on betacyanins and antioxidant activity of the peel and fresh extract from the red pitaya (Hylocereus polyrhizus). The peel and flesh extracts obtained by SFE at 25MPa pressure and 10%...
