Abstract

Cottonseed proteins were acetylated or succinylated to different levels, and N solubility in water or 5% NaCl solution, water absorption and oil absorption capacity, emulsification capacity, foam capacity and foam stability, bulk density, and in vitro digestibility of cottonseed flour were determined. Acetylation decreased N solubility in water or 5% NaCl whereas succinylation increased it. Water absorption capacity did not change due to succinylation but increased due to acetylation. On the other hand, high levels of acetylation or succinylation decreased oil absorption capacity. Emulsifying capacity increased initially on acylation and then decreased. Foam capacity increased but foam stability decreased on acylation. Bulk density increased due to modification but in vitro digestibility was not affected.
