本文以干制蕨菜为原料，利用水提醇沉法得到蕨菜粗多糖，然后采用对氨基苯磺酸-盐酸萘乙二胺分光光度法进行其对亚硝酸盐清除效果的研究。通过单因素及正交实验分析多糖浓度、反应时间、反应温度对亚硝酸盐清除作用的影响。结果表明，当蕨菜多糖溶液浓度为20mg/mL时，50℃条件下加热15min，亚硝酸盐清除率为41.1%，效果最好。
本文以榦製蕨菜為原料，利用水提醇沉法得到蕨菜粗多糖，然後採用對氨基苯磺痠-鹽痠萘乙二胺分光光度法進行其對亞硝痠鹽清除效果的研究。通過單因素及正交實驗分析多糖濃度、反應時間、反應溫度對亞硝痠鹽清除作用的影響。結果錶明，噹蕨菜多糖溶液濃度為20mg/mL時，50℃條件下加熱15min，亞硝痠鹽清除率為41.1%，效果最好。

The nitrite scavenging effect of bracken polysaccharide was mensurated by aniline-sulfonic and hydrochloride acid-naphthylamine ethylenediamine through spectrophotometry. This polysaccharide was extacted from dry bracken with water extract-alcohol extraction method. Based on the single factor experiment and orthogonal test, the influences of polysaccharide concentration, reaction time, reaction temperature on nitrite scavenging were discussed. The results showed that the process optimization on nitrite scanvenging were polysaccharide concentration 20mg/mL, and heated at 50℃ for 15min respectively. It’s scanvenging rate of nitrite reached up to 41.1%.
