Abstract
The filtration effects of glass membrane filters and hollow fiber membranes with different pore size to prevent the haze of a commercial foxtail millet Yakju were investigated. The most particles(haze precusors) present in the Yakju were removed by using 1.2 $\mu\textrm{m}$ glass membrane filter. In case of using 0.45$\mu\textrm{m}$ hollow fiber membrane system, the permeate flux on the Yakju filtration was calculated to 342.8 lmh. During the 3 month storage at 4$^{\circ}C$ and room temperature for each 48 hrs in turn, alittle fine haze was observed from the Yakju even if it was filtered by using 0.7 $\mu\textrm{m}$ glass membrane filter. Anything of haze was, however, observed from the Yakju filtered by using all of hollow fiber membranes. Therefore, the 0.45$\mu\textrm{m}$ hollow fiber membrane system was effective as a final filtration process of the Yakju.
