The capacity and stability of CFP increased when ballmilling time was increased from 0 to 6 min, which might be due to the increase of surface hydrophobicity after ball mill treatment. In hydrolysates of different stages of digesting, the number of peptides with 710 amino acids increased with increasing ballmilling time.

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
