- Abstract
Background: Berberis vulgaris L. is a valuable source of natural antioxidants, polyphenols, and anthocyanins compounds. Advanced extraction methods can increase extraction efficiency. This study investigated the efficiency of pulsed electric field, vacuum-cold plasma, and enzymatic pretreatment for anthocyanins extraction of Berberis vulgaris L. Results: Total polyphenols (TP), total anthocyanin (TA), and physicochemical properties of Berberis vulgaris L. were investigated. The pulsed electric field at three levels of electric intensity (3000, 5000, and 7000 V/cm) and three pulse numbers (50, 75, and 100) were applied. 7000 V/cm with the pulse number of 100 was the best condition for anthocyanin extraction (amounts of anthocyanin and polyphenol extraction were 260.28 mg/L and 462.75 mg/L, respectively). The vacuum-cold plasma was carried out at the power of 60, 70, and 80 w at different times (1, 3, and 5 min). The optimum conditions for vacuum-cold plasma were 80 w for 5 min, and anthocyanin and polyphenol amounts were 256.32 mg/L and 433.71 mg/L, respectively. The optimal conditions of enzymatic pretreatment for the maximum yield were 1.5% enzyme concentration at 60 °C (the values of extracted anthocyanin and polyphenol were 279.64 mg/L and 484.93 mg/L, respectively). Conclusions: Different extractionpretreatments demonstrated that the enzymatic pretreatment resulted in the highest extraction of anthocyanins and polyphenols from Berberis vulgaris L. Therefore, pectinase can act as a potential assisted extraction for the extraction process. Highlights: Pulsed electric field, cold plasma, and pectinase were used for Barbery anthocyanins extraction. Vacuum-cold plasma as novel assisted extraction technology improved anthocyanins extraction. Pulsed electric field enhanced anthocyanins extraction efficiency of Berberis vulgaris L. The enzymatic pretreatment appears as the best pretreatment prior to anthocyanin extraction.
