Embodiment 1
[0022] The preparation of embodiment 1 quaternized gluten protein hydrolyzed peptide
[0023] Prepare a 1.5mol / L hydrochloric acid aqueous solution, slowly add N, N-dimethyldodecyl tertiary amine (hereinafter referred to as tertiary amine) in an equimolar amount to HCl while stirring, to generate tertiary amine hydrochloric acid Saline solution (I). Keep stirring the solution, slowly heat it up to 65°C, then slowly add epichlorohydrin (II) dropwise, the molar ratio of epichlorohydrin to tertiary amine is 0.95:1, keep the reaction for about 2 hours, until the pH of the reaction system is basically lower. Change again to obtain the product (Ⅲ). Reaction 2 is the hydroxyl ring closure reaction in quaternization. After the product (II) solution was cooled to room temperature 25°C, NaOH solution with a mass concentration of 25% was added dropwise to adjust the pH value to 12 (±0.1), stirred and maintained for about 3 hours. The product (IV) is obtained after the reaction is fini...
