为了探索红茶菌菌液预防胃肠癌的保健机理,初步研究了红茶菌菌液对亚硝酸盐的降解效果。结果表明：红茶菌菌液能够快速降解亚硝酸盐,同时在降解过程中产生大量的NO。在红茶菌菌液中添加100~1 000 mg/L的亚硝酸钠,红茶菌菌液在2 h内的降解量可达到89.02~431.16 mg/L;在红茶菌菌液中添加5~200 mg/L的亚硝酸钠,红茶菌菌液在20 min内可产生52.3~376.1 mg/m3浓度的NO。
In order to explore the health-protecting mechanism of Kombucha tea in the preventing of gastrointestinal cancer and other diseases, degradation of nitrite in vitro by Kombucha tea was preliminarily studied. The results showed that Kombucha tea could efficiently degrade nitrite in vitro and generate a lot of NO. 100~1 000 mg/L of sodium nitrite were added in the Kombucha tea, the degradation of nitrite by kombucha tea was up to 89.02~431.16 mg/L in 2 h. 5~200 mg/L of sodium nitrite could be efficiently degraded by kombucha tea, which could generate 52.3~376.1 mg/m3 of NO in 20 mins.
