Hardness of protein gel can be improved by ISP at pH 3.5, 11.0, 11.5 and 12.0
ISP processing at pH 3.5 and 11.0 can efficiently decrease the water loss.
Alkaline treatment contributed to whiter protein gel.
ISP-extracted sample formed low elasticity gel.
ISP have potential to enhance gelation properties of PSE-like chicken meat protein.
