PURPOSE:To obtain an oligopeptide mixture rich in both highly digestible peptides and glutamine by hydrolyzing wheat protein under specified conditions with an alkali protease produced by Bacillus bacteria. CONSTITUTION:The oligopeptide mixture can be obtained by hydrolyzing wheat protein with an alkali protease at pH8.0-11.0 (pref. 9.0-10.0) at 40-70 (pref. 50-60) deg.C for 5-30 (pref. 10-20) hr. This mixture has the following characteristics: (1) weight-average molecular weight: 200-1000; (2) total content of dipeptide plus tripeptide: >=50wt.%; (3) free amino acid content: <=10wt.%; and (4) glutamine content: >=30wt.%. |
