Abstract
The utilization of cottonseed meal and its extracted protein powder as valuable industrial products necessitates leveraging. The surface characteristics and qualitative parameters were evaluated by using FTIR, SEM, color and protein digestibility, lysine content, and microbial analysis respectively. CSPC and MW-CSPI had parallel β plated sheets and an accumulation of tiny particles due to soluble and insoluble pentosans, with changes resulting from the alkali salt protein extraction process. CSPC had superior in-vitro protein digestibility and microbiological analysis showed safe limits for bacterial and pathogenic bacterial count. Cottonseed protein, whether untreated or microwave pre-treated, can be used as an ingredient or supplement in various foods, except for lysine content as specified in Food Safety and Standards Regulations of 2011.
