To solve the problem with product development in which ergothioneine-containing liquid compositions obtained from ergothioneine-containing raw materials have low photostability of ergothioneine.SOLUTION: Ergothioneine-containing liquid compositions are obtained from ergothioneine-containing raw materials and contain ascorbic acid with ergothioneine serving as a stabilizer, thereby enhancing the photostability of ergothioneine.SELECTED DRAWING: Figure 2 【課題】エルゴチオネイン含有原料から得られたエルゴチオネイン含有液体組成物では、エルゴチオネインの光安定性が低く、製品開発の問題となることが見いだされた。【解決手段】エルゴチオネイン含有原料から得られたエルゴチオネイン含有液体組成物であって、エルゴチオネインを安定化剤として、アスコルビン酸を含むエルゴチオネイン含有液体組成物を提供することにより、エルゴチオネインの光安定性が亢進した。【選択図】図２
