Study on Scavenging and Disconnecting Effects of Nitrosation Reaction by Extracts of Tetradium Ruticarpum and Glycyrrhizae

In order to investigate and compare the effects of Tetradium ruticarpum and Glycyrrhizae extracts in terms of scavenging sodium nitrite and inhibiting N-ni- troso compounds formation, the 1_9（3^3） orthogonal test was conducted to extract the active components. In addition, the capacities of scavenging sodium nitrite and of in- hibiting the N-nitroso compounds formation were measured to confirm the optimum condition of extracting. When the scavenging rate was considered as the main index, the maximum capacities of scavenging sodium nitrite by the extracts of Tetradi- urn ruticarpum and Glycyrrhizae were 0.836 5 and 0.558 0, respectively. Further- more, when the disconnection rate was considered as the main index, the maximum capacities of inhibiting the N-nitroso compounds formation by the extracts of Tetradi- urn ruticarpum and G/ycyrrhizae were 0.922 8 and 0.625 6, respectively. As a re- suit, the capacity of inhibiting nitrosation reaction by Tetradium ruticarpum was shown to be much stronger than G/ycyrrhizae, no matter the scavenging rate or the disconnection rate as the main index to be considered.

烹饪过程中控制食物的安全性问题之研究

当今社会“绿色”、“环保”巳成为人们最关心的话题。无公害的绿色材料，元氯的绿色冰箱，尤其是无污染的绿色食品越来越受人们的亲睐。如何将绿色食品材料加工成可直接入口的绿色烹饪制品，烹饪过程中如何控制事物的安全性问题，巳成为烹饪界人士的广泛关注与探讨。
