In the study, scientists worked to break down leftover soybean material using two enzymes called papain and flavourzyme. They figured out the best amounts and times for the enzymes to do their job effectively. With papain, a ratio of 600 units per gram of soybean worked well, while flavourzyme needed 1200 units per gram. The flavourzyme needed about 14.5 hours to work its magic, and the whole process took 16 hours. Using 2% soybean material was just right. After the enzymes were finished, 55.73% of the total nitrogen in the soybean residue was recovered.
