posted on 2018-05-31, 15:41 authored by Warren P. EaglesWhen filtering beer at pore sizes of 0.45 μm and below, some desirable components
may be lost, even though they are orders of magnitude smaller than the pores. In this
work, a model beer solution of pure components has been filtered through 0.2 μm
membranes to investigate this problem. Starch (a model for the long chain
carbohydrates) at a concentration of 1500 mg.l-1 and casein (a model for the protein
fraction) at a concentration of 150 mg.l-1 were found to result in reduced permeate
fluxes in the region of 20–40 l.m-2.h-1. [Continues.]
