Resumen de: EP4666997A1
The present invention discloses a process for producing yeast cell wall extract hydrolysate using organic acid. The process removes color and odor substances and inorganic salts carried by yeast after fermentation and cultivation through preliminary hydrolysis with acetic acid and purifies the yeast cell wall extract at the same time. Then, the yeast cell wall extract from which color and odor substances and inorganic salts have been removed is hydrolyzed with formic acid to make the produced yeast cell wall extract hydrolysate more easily soluble in water. Through the above organic acid hydrolysis process, the present invention provides a production process for a colorless, odorless, salt-free and easily soluble product containing substances in yeast cell walls that are beneficial to skin protection, repair and treatment. The present invention also provides a method for removing and recycling the organic acids added in the process, thereby reducing production costs and reducing pollution.
