he 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 150 kDa. Proximate
and HPLC analyses revealed that the obtained samples were enriched with basic nutrients and well-balanced
amino acids composition, respectively.
