摘　　要：目的:探讨青天葵提取液对螺蛳粉及腌制品中亚硝酸盐的清除作用。方法:以国标GB 5009.33—2016中盐酸萘乙二胺法检测螺蛳粉中亚硝酸盐含量。利用乙醇为溶剂提取青天葵有效成分,进行单因素试验和L9(34)正交试验优化青天葵提取液清除食品中亚硝酸盐的最佳条件。结果:青天葵提取液清除亚硝酸盐的最优条件为提取液3 mL(料液比1∶15,g∶mL)、反应温度80℃、pH为8.0。对螺蛳粉中亚硝酸盐的清除率为汤汁27.56%、粉31.75%、配菜34.74%、每碗粉为39.27%。对腌制肉制品腊肠、腊肉中亚硝酸盐的清除率分别为30.31%、35.25%。结论:青天葵提取液对亚硝酸盐有一定的清除作用,该研究可为今后开发利用青天葵资源,降低食品中亚硝酸盐的含量,提高螺蛳粉食用安全性提供科学依据。Objective:Investigate the elimination effects of Nervilia fordii extracti on nitrite in snail rice noodles powder and cured food.Method:In GB 5009.33—2016 hydrochloric acid naphthalene ethylendiamine.Ethanol was used as the solven to extract the effecttive components from Nervilia fordii.The single-factor experiment and L9(3~4)orthogonal were carried out to optimize.Result:The optimun condintions for the extraction and removal of nitrite from food.The results indicated that optimun extraction technology of Nervilia fordii extrac paramrters for 3 mL(solid-liquid ratio is 1∶15,g∶mL),temperature of 80℃and pH 8.0.Under such condition,removal rate of nitrite of spoon meat was 27.56%,powder 31.75%,side dish 34.74%with one of flour was 39.27%.The removal rate of nitrite in preserved meat products sausage and bacon were 30.31%and 35.25%respectively.Conclusion:The Extraction of Nervilia fordii had certain scavenging effect on removal of nitrite.This study can provide scientific basis for the development and utilization of Nervilia fordii resources in the future,reduce the content of nitrite in food,and improve the food safety of snails powder.
