Abstract:

The effects of tea fungus on polyphenol oxidase activity, L* value, vitamin C content and issue hardness during the ripening process of fresh-cut potato stored at 4 ℃ for 5 days were investigated. The results indicated that the tea fungus could significantly inhibit the polyphenol oxidase activity of potato, and positively keep the content of vitamin C and issue hardness of potato, but has little effects on the L*-value. In conclusion, tea fungus can prevent the browning of fresh-cut potato, which may be due to the fermentation of black tea soup by tea fungus.

Key words: fresh-cut, potato, tea fungus, browning
