Comparison of Enzyme-assisted and Ultrasound-assisted Extraction of Albumin from Defatted Rambutan (Nephelium lappaceum L.) Seed

Rambutan fruit is a popular crop widely cultivated in South East Asia. Rambutan seed is an important residue in fruit processing industry. Lipid extraction from rambutan seed has widely been reported while study on protein profile of rambutan seed has not been considered. Our preliminary study showe...
