Embodiment 1
[0022] Example 1 Preparation of quaternized gluten proteolytic peptide
[0023] Prepare 1.5mol / L hydrochloric acid aqueous solution, and slowly add N,N-dimethyldodecyl tertiary amine (hereafter referred to as tertiary amine) in an equimolar amount of HCl while stirring to the hydrochloric acid solution to generate tertiary amine hydrochloric acid Salt solution (I). The solution is kept stirring, slowly heated to 65°C, and then epichlorohydrin (II) is slowly added 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 not Change again to obtain product (III). Reaction 2 is a hydroxyl ring-closure reaction in quaternization. After cooling the product (II) solution to room temperature and 25°C, add dropwise NaOH solution with a mass concentration of 25%, adjust the pH to 12 (±0.1), stir and maintain the reaction for about 3 hours. After the reaction, the product (IV) is obtaine...
