Antioxidant Capacity of Rapeseed Extracts Obtained by Conventional and Ultrasound-Assisted Extraction

Ultrasound-assisted extraction (UAE) and conventional solid-liquid extraction were applied to extract total antioxidants from two rapeseed varieties. The antioxidant capacities (AC) of winter and spring rapeseed cultivars were determined by four different analytical methods: ferric reducing antioxidant power (FRAP), cupric reducing antioxidant capacity (CUPRAC), 2,2'-diphenyl-1-picrylhydrazyl (...

Kinetic modeling of pectin extraction by ultrasound assisted and conventional methods

The goal of this study was to investigate the most suitable kinetic models for pectin extraction by way of ultrasound-assisted extraction (UAE) and conventional heating extraction (CHE) with acid from melon peel. The ultrasound and acidic assisted extraction were performed on powdered melon peel in three different temperatures of 40-55-70°C and 50-70-90°C, respectively. It was observed that, in...

Microwave‐assisted extraction and ultrasound‐assisted extraction for recovering carotenoids from Gac peel and their effects on antioxidant capacity of the extracts

The peel of Gac fruit (Momordica cochinchinensis Spreng.) contains high levels of bioactive compounds, especially carotenoids which possess significant antioxidant capacities. However, the peel of Gac is regarded as a waste from the production of carotenoid-rich oil from Gac fruit. In this study, carotenoids of Gac peel were extracted by microwave-assisted extraction (MAE) and ultrasound-assist...
