Optimization of Cell Disruption for Alfalfa Leaf Protein ...

ABSTRACT Leaf protein concentrate (Pro‐Xan) production requires cell maceration for protein release. Alfalfa cell rupture was studied with a commercial scale vertical hammer mill with respect to feed rate, hammer‐wall clearance, type and number of hammers, agitation rate, energy input, and juice recycle. Degree of cell rupture was measured by comparing the amount of true …
