Methods for removing iron from saké were investigated. Adsorption rate of iron by active carbon was closely related to the rate of decolorization (r=0.759**, n=31). Only about 70% of iron was removed from sake after the addition of active carbon in an amount 1% to the sake. Of other adsorbents, phytic acid or phytin was effective to remove iron from saké. Phytin treatment (0.5%) after the treatment with active carbon (1%) was most effective, and 96.6% of iron was removed from saké containing 19.0 ppm Fe
3+.

Activity of active carbon in preventing color development of saké caused by exposure to sunlight was investigated. The activity was closely related to the rate of adsorbing ferricyanide-reducing substances (FRS) in saké(r=0.891, n=28).
FRS in saké were mainly contained in the fraction adsorbed by Amberlite IR-120, II type. Of many adsorbents active carbon had the most powerful activity of prevention.
As standard substances for measuring the activity of active carbon, tryptophan and deferri-ferrichrysin were selected, because the adsorption rate of tryptophan or deferri-ferrichrysin by active carbon was closely related to the color development of sake treated with the same active carbon (r=-0.879** and -0.842**, respectively).

In order to establish the method for analyzing phenolic compounds in sake, chromatographic behaviors of 46 authentic phenols on silicic acid column, polyamide column and Avicel thin-layer were studied. And combination of these chromatographies was proved useful for the separation of phenolic constituents in sake.

Reducing substances in the ether extractable fraction of sake were analyzed by the method discribed in the previous report. Tyrosol,
p-hydroxybenzaldehyde,
p-hydroxybenzoic acid,
p-hydroxyphenylacetic acid,
p-hydroxycinnamic acid, vanillic acid, ferulic acid, protocatechuic acid, mono-(
p-hydroxy phenethyl)-succinate, tryptophol, indolacetic acid, and N-acetyltryptophane were found.
