Abstract

Three trials were conducted to study the optimum conditions required for production of protein hydrolysates from palm kernel meal and Jatropha curcas seed meal. Hydrochloric (HCl) and sulphuric (H2SO4) acids of varying concentrations (2, 4, 6, 8, and 10 moles dm-3) were tested for hydrolysis of each of the two plant sources at different temperatures (65, 80, 95, 110, and 125oC) and for different durations (6, 12, 18, 24, and 30 h). Results indicated that with both acids, protein hydrolysates yield and amino acid decomposition were positively and significantly correlated with acid concentration, temperature and duration of hydrolysis. However, HCl produced higher yield of hydrolysates with lower decomposition of amino acids from both protein sources. High yield of hydrolysates coupled with higher degree of amino acid decomposition were observed in J. curcas seed meal than in palm kernel meal. Optimum yield of hydrolysates was obtained from J. curcas seed meal when hydrolysed with either 6 moles dm-3 HCl or 8 moles dm-3 H2SO4 at 95oC for 18 h. In case of palm kernel meal, optimum yield was achieved at 110oC with either 8 moles dm-3 HCl or 10 moles dm-3 H2SO4 for 24 h and 18 h, respectively.
