Effect of co-extraction of pomegranate seed oil with green tea leaves on the extraction yield and quality of extracted oil

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 analysis also confirmed PV results, therefore using GTL led providing highest induction period (11.5 h). Consequently, could result an appropriate present higher oxidation stability. This method does not need any antioxidant from herbs is very cost-effective, time-efficient, uses no chemicals.
