Description
Summary:Grape is an important crop spread around the world and present high contents of bioactive compounds. Large amounts of grape pomace are produced by food industries and are considered as rich sources which can contribute to health-promoting phytochemicals such as anthocyanins. These compounds can be separated using different adsorbents. Macroporous adsorption resins (MARs) have been reported as the most efficient method for polyphenols recovery. In this study, the adsorption and desorption characteristics of anthocyanin using six MARs were evaluated. XAD-7HP showed the highest adsorption and desorption capacities. The kinetic and isotherm tests indicated that the adsorption mechanism was better explained using pseudo-first-order kinetic and the Langmuir isotherm model. The adsorption process presented exothermic behavior on XAD 7HP when performed at 30 °C in relation to 40 °C and 50 °C. The initial and purified extracts were rich in acylated anthocyanins (67.06%) and (71.33%), respectively, the results of antioxidant tests indicate that purified anthocyanins extracts showed high antioxidant capacity in the both methods of FRAP and DPPH 12.75 and 12.06 mg TE g −1 respectively. According to HPLC analyses, MARs have shown great potential as an efficient technology for the separation and purification of anthocyanins from food waste and as raw material for different applications in the food and pharmaceutical industries.
