JUDGMENT OF QUALITY OF MALT OR THE LIKE

摘要

PURPOSE:To judge the quality of malt by discriminating superiority or inferiority of strength of enzymic power of malt for beer production, distinction of winter sowed malt and spring sowed malt, etc., by reacting a test malt with an aqueous solution of an oxidation-reduction indicator to observe the color of the malt or indicator after the lapse of a given time. CONSTITUTION:A test malt is reacted with an aqueous solution of an oxidation- reduction indicator to observe the color of the malt or indicator after the lapse of a given time and judge the quality of the malt, etc. Preferably, an aqueous solution of 0.001-0.2% resazurin sodium salt adjusted to about 7pH is used as the aqueous solution of the oxidation-reduction indicator, and the salt is dipped in the aqueous solution to observe the color of the malt or the aqueous solution after 6hr. Thereby, the malt can be judged whether it is winter sowed malt or spring sowed malt by the difference of the color.
