Co-extraction of pomegranate seed oil (PSO) with green tea leaves (GTL) (0 [control sample], 2.5, 5, 7.5, and 10% w/w) was conducted by cold-press to evaluate the extracted quality during storage. The extraction yield similar control sample up 5% w/w GTL. Total phenol chlorophyll content were increased in oils increasing level acid peroxide values storage lowest achieved for PSO Rancimat analys...

recently, subcritical water extraction (swe) has been well known as a green technology for extraction of bioactive compounds from plants. in this study, subcritical water extraction, ultrasound assisted extraction (uae) and shaker solvent extraction (sse) were compared for extraction of phenolic compounds from fig (ficuscarica) pulp and skin. antioxidant activity of the extracts was evaluated u...

4 different plant species belonging to the same family mint (Mentha piperita), sage (Salvia officinalis), rosemary (Rosmarinus lavender (Lavandula angustifolia) were harvested from Afyon region. Total antioxidant and phenolic contents analyzed by DPPH Folin-Ciocalteu method. The effect of extra virgin olive oils oxidation stability was tested means rancimat According analysis results, M. piperi...

This study aimed to search for the optimum antioxidant mixture improvement of stability high-oleic sunflower oil. Seven antioxidants including vitamin E, phytic acid, bamboo leaves, rosemary extract, tea polyphenols, ascorbyl palmitate (AP) as well polyphenol (TPP) were used. Peroxide value, free radicals and Rancimat induction time results all proved that TPP was best single antioxidant. There...

Abstract A non-destructive fluorescence method combined with chemometric algorithms has been developed for discriminating between olive oils. The excitation-emission matrices (EEMs) of two oil varieties (Arbosana and Oliana) from crop seasons, which had undergone different irrigation treatments (control strategy regulated deficit (RDI)), were recorded. EEMs analysed using parallel factor analys...
