内容記述 | An inhibitory effect on the black discoloration of perishable food by a culture supernatant of fungi isolated from marine sediment gathered off the Niigima Islands was studied at the enzyme and application levels. The fungus was identified as Trichoderma sp. from a taxonomic study. The strain was incubated in 100ml of broth composed of 2% glucose and 0.5% Bacto-peptone, pH 8.0, in a baffled 500ml Erlenmeyer flask at 27°C for 4 days on a rotary shaker (160rpm). After incubation, the culture was harvested by centrifugation and a supernatant was used for the present study. The inhibitor was stable for more than 50 days under conditions of -20°C and -80°C without reduction of the inhibitory activity. When the supernatant was boiled for 30min, the inhibitory activity was reduced by about 50%. However, more than 90% of the activity remained after proteolytic enzyme digestion with papain, suggesting that the inhibitor might be applicable in preventing the black discoloration of perishable food. A remarkable preventative effect on the black discoloration of cultured prawns was observed in the presence of 0.2% culture supernatant. In addition, the supernatant diluted with 50% water also showed a 70% reduction in the black discoloration of fresh apple, eggplant, and mushroom. These results suggested that the inhibitor might be applicable to the preservation of perishable foods. | |||||
