Description The aim of the present study was to utilize the protein from pigeon pea milling waste by-product for the
preparation of protein isolate (PPI). The PPI was exposed to pepsin hydrolysis to reveal functional aspects
like increased antioxidant capacity along with gelling ability. Complexation study demonstrated use of PPI as
an encapsulating material for water insoluble bioactive compounds (curcumin). Fluorescence spectroscopy
revealed the formation of a complex through hydrophobic interaction. Ex-vivo digestibility of PPI’s major
proteins resulted in many peptides after digestion with human gastrointestinal enzymes. The peptide
sequences identified may have potential biological activities as revealed by bioinformatic data analysis. The
presence of bioactive peptides and essential amino acids in the ex-vivo digest suggests the role of PPI as a
nutraceutical protein. The study provides a new value addition to the pigeon pea milling waste by-product, as
a novel nutraceutical protein which can be used in functional food formulations.
