The purification of papain using a reversed phase expanded bed adsorption chromatography (RP-EBAC)
using a FastlineTM 10 EBAC column packed with AmberliteTM XAD7HP has been carried out in this study.
An efficient large scale direct recovery of papain was developed and optimized from unclarified papaya
juice feedstock in batch adsorption system. Enhancement of papain purity was further investigated in
EBAC by stepwise elution strategy. High papain purity of 74.98% and high purification factor of 7.04 were
obtained. This study shows a great potential of using two step elution RP-EBAC system to purify papain
from unclarified papaya juice.
