摘要
对牛蒡中所含的多酚氧化酶的活性及其影响因素的研究表明，牛蒡中多酚氧化酶的适宜ｐＨ值是６．０～７．５，适宜温度４５℃，较有效的抑制剂是２％钾明矾和０．０２％ＳＳＡ的混合液，或０．５８％磷酸和０．０２％ＳＳＡ的混合液．用此溶液浸泡过的牛蒡，再用ＨＰＥ薄膜袋包装后，在－４０℃下速冻，放在－１８℃冷冻库保存，贮藏期达６个月以上．
Results of the study on the activity and influence factors of polyphenoloxidases (PPO) of arctium lappa L. have been shown. The suitable pH is 6.0～7.5 of PPO in arctium lappa L.. The suitable temperature is 45℃. The quite good inhibitor is the mixed solution of the 2% potassium alum and the 0.02% sodium sulfite crystal or the 0.58% phosphoric acid and the 0.02% sodium sulfite crystal. The arctium lappa L. that had been soaked in these mixed solution can be storaged over the 6 months at a temperature of the -18℃ with the use of HPE paceing and -40℃ freezing.
