PreventionofMustyOdor（TCA）MigrationintoFoodstuffs（２） Clarification of the Migrating Mechａｉｓｍｓ ｏｆ ＴＣＡ ａｎｄ ｉｔｓ Ｐｒｅｖｅｎｔｉｏｎ

Abstract

(TCA), which has an extremely low sensory threshold level, causes musty ooor in foods. The mechanisms of TCA migration in the proce函ing of foods were elucidated. Two main migration routes were clarified : 1) the processed foods (ex. bottled) are tainted by TCA migrating through closures dwing their storage from the outer TCA rich atmosphere., or 2) raw materials or the containers themselves are previously tainted by TCA migrating through their packaging materials. • of higher gas barriered packing materials or cap liners cleary prevented the TCA into processed foods. Several other methods to prevent TCA migration are also discussed.
