PROBLEM TO BE SOLVED: To provide a method for preventing discoloration of fresh food by which appearance of fresh food such as fish or shellfish is prevented from discoloration into brown or black with time. SOLUTION: The method comprises treating fresh food with culture supernatant components separated from culture solution obtained by culturing oceanic filamentous fungi for a prescribed period of time. The culture supernatant comprises such one obtained by separately eliminating the oceanic filamentous fungi from culture solution obtained by culturing the separated oceanic filamentous fungi with culture media containing water, 0.1-4.0 wt.% of a C source and 0.1-2.0 wt.% of an N source, and having the NaCl concentration of ≤0.05 wt.% at 20-30°C for prescribed period of time.

PROBLEM TO BE SOLVED: To provide a fruit wine containing a polyphenol oxidase inhibitor having high effect for preventing browning and safety without causing problems even when used in fruit wines wherein a difference in delicate flavors or tastes cause the problem and without affecting a brewing step, and to provide a method for producing the fruit wine. SOLUTION: The fruit wine includes a culture supernatant of a microorganism inhibiting the activity of polyphenol oxidase and/or a treated substance thereof. Furthermore, the method for producing the fruit wine includes adding the culture supernatant of the microorganism inhibiting the activity of the polyphenol oxidase and/or the treated substance thereof before or during crushing of fruits. In addition, the polyphenol oxidase inhibitor is an additive for inhibiting the browning of the fruit wine, and includes the culture supernatant of the microorganism and/or the treated substance thereof.
