Sequential fractionation of value-added coconut products using membrane processes

The coconut waste-skimmed coconut milk was employed for sequential fractionation using UF and NF membranes to produce value-added products (coconut proteins, plant hormones – kinetin and zeatin). The retention factors achieved by UF membrane (PS10): albumin (0.9822±0.0799) and globulin (0.9975±0.078...

Summary:The coconut waste-skimmed coconut milk was employed for sequential fractionation using UF and NF membranes to produce value-added products (coconut proteins, plant hormones – kinetin and zeatin). The retention factors achieved by UF membrane (PS10): albumin (0.9822±0.0799) and globulin (0.9975±0.0783); NF membrane (NF1): kinetin (0.9238±0.0345) and zeatin (0.9511±0.0355). Coconut protein powder was obtained after spray-drying process using concentrated coconut protein (UF retentate). SDS-PAGE showed that molecular weights of the coconut proteins were 17, 34, 55 and 150kDa. Proximate and HPLC analyses revealed that the obtained samples were enriched with basic nutrients and well-balanced amino acids composition, respectively.
