| 摘要 |
The invention provides a method for hydrolysing protein with hydrochloric acid in which the hydrolysis reaction is carried out at a temperature of between 60 and 97 DEG C and that the reaction temperature is increased to 100-110 DEG C over a reaction period of between 2-24 hours and that the reaction mixture is kept at such a higher temperature for a period of 15 minutes to 2 hours followed by cooling, neutralizing and filtering. Preferably the temperature is gradually and continuously increased at a rate of 0.01-0.3 DEG C per minute. |
