| abstract |
An adsorbent is described, which has a pore structure suitable for the selective and efficient removal of bitter components from fruit juice, and which does not contain ionic functional groups or the like in the structure thereof and can be easily handle, and more specifically, which comprises a porous crosslinked polymer produced from an aromatic vinyl monomer compound, and in which the specific surface area per dry unit weight, the pore volume per water-wet unit volume, and the specific surface area attributable to pores having a radius not smaller than 50 ANGSTROM per water-wet unit volume are not smaller than respective specific values. A process for producing the adsorbent and a method of treating fruit juice using the adsorbent are also described. |
