Optimization of phenolics extraction from sesame seed cake

Effect of pulsed electric fields and high voltage electrical discharges on polyphenol and protein extraction from sesame cake

“…The extracted amount of polyphenols, in the different conditions, ranged between 54.3 and 440.3 mg GAE/100 g and the lignan content varied from 63.9 to 242.9 mg SE/100 g DM (dry matter). These values are in the same range found in our previous studies (Sarkis, Michel, Tessaro, & Marczak, 2014) and in literature (Moazzami et al, 2006b;Suja, Jayalekshmy, & Arumughan, 2005). The extract protein content was between 374 and 2001 mg BSA/100 g DM.…”

“…4(b)). Higher concentrations of ethanol were necessary for extraction of lignans than total polyphenols; this behavior was expected since it has been observed in previous work (Sarkis et al, 2014). Apart from the optimum solvent, results were very similar to what has been previously observed for polyphenols.…”

“…2(b). The mixing of ethanol in the extracting medium has a significant effect on the extraction of polyphenols from sesame seed cake up to a certain amount, as it has been shown in previous work (Sarkis et al, 2014).…”

Stability of 40 phenolic compounds during ultrasound-assisted extractions (UAE)

“…These preliminary temperatures were set with respect to the lowest and highest temperatures that could produce adequate precision by UAE system. A binary solvent of methanol: water was chosen as this normally used for the extraction of phenolics from foods [12][13][14].…”

Avaliação dos compostos bioativos presentes na semente de <i>Passiflora</i> spp. e sua influência sobre marcadores bioquímicos, oxidativos e inflamatórios de camundongos submetidos à dieta hiperlipídica

“…É importante considerar que o papel de cada fator no processo de extração não é sempre óbvio (SARKIS et al, 2014) Assim, a extração de compostos polifenólicos com características antioxidantes pode ser considerada como mais uma alternativa interessante para obtenção de importantes ingredientes industriais e com importância biológica e valoração de um subproduto, que, na maioria das vezes, é considerado um resíduo. …”
