【中文摘要】 試驗比較了60Co—r 射線輻照、氣調(diào)、藥劑等保鮮方法對雙孢蘑菇保鮮的效果,得出以紙塑袋密封包裝,加天然去異味劑,采用自發(fā)氣調(diào)法保鮮,效果最佳。在5℃左右溫度條件下可以保存10—15天,開傘率不超過3%,基本無褐變和異味,失重率在2%以內(nèi),質(zhì)地基本不下降。同時,研究了自發(fā)氣調(diào)保鮮的作用機(jī)制,證明自發(fā)氣調(diào)保鮮法,氧與二氧化碳分壓可分剮調(diào)整到2—3%和10—15%,在這種條件下,多酚氧化酶的活性明顯下降。

【英文摘要】 The experiments researched the effect of keeping fresh white mushroom with the irradiation of 60Co r-rays,the controlled atmosphere(CA) and the chemical treatment,etc.The modified atmosphere(MA) appers to be the best method.Using MA method when packed in sealed paper-plastic bag and put in the natural inhibitor of peculiar smell,fresh white mushroom can be stored for 10—15 days in 5℃.The rate of cap opening and weight loss are respective lower than 3% and 2%;Moreover,the texture,odour and colour are basically well kept.Furthermore,we researched the function mechanism of MA,there are a distinet drop in the PPO activity when the concentrations of O_2 and CO_2 are separately regulated to 2—3% and 10—16%.
