一、“充氮(dan)保鮮"技術是什么？

食(shi)(shi)用油(you)(you)主要成(cheng)分是(shi)甘油(you)(you)和脂肪酸(suan),極易被氧(yang)化而產(chan)生(sheng)酸(suan)敗現象(xiang),影(ying)響(xiang)口(kou)感、破壞(huai)營養(yang)價值,產(chan)生(sheng)對(dui)人體有害(hai)成(cheng)分。而“充氮(dan)保鮮"就是(shi)用氮(dan)氣(qi)置換出空氣(qi),讓食(shi)(shi)用油(you)(you)不與(yu)空氣(qi)里的氧(yang)氣(qi)直接(jie)接(jie)觸,從而達(da)到延長食(shi)(shi)用油(you)(you)的保質期,而氮(dan)氣(qi)屬于惰性氣(qi)體無害(hai),不會使(shi)食(shi)(shi)用油(you)(you)氧(yang)化變質。

食用(yong)(yong)油(you)裝罐完畢后向(xiang)瓶(ping)(ping)中充入氮氣(qi)(qi)，使瓶(ping)(ping)內的(de)空氣(qi)(qi)和食用(yong)(yong)油(you)內氧(yang)(yang)氣(qi)(qi)被置換出來，然后壓蓋密封(feng)，這樣(yang)一方(fang)面使得(de)瓶(ping)(ping)內氧(yang)(yang)化(hua)食用(yong)(yong)油(you)的(de)氧(yang)(yang)氣(qi)(qi)殘留非(fei)常低，食用(yong)(yong)油(you)沒有可供(gong)反應的(de)氧(yang)(yang)氣(qi)(qi)源；另一方(fang)面，氮氣(qi)(qi)在瓶(ping)(ping)的(de)頂空部(bu)分形(xing)成了氮封(feng)，阻隔了氧(yang)(yang)氣(qi)(qi)與食用(yong)(yong)油(you)的(de)接觸，達到了保護食用(yong)(yong)油(you)，防止食用(yong)(yong)油(you)氧(yang)(yang)化(hua)的(de)效(xiao)果，同時可以避免人(ren)工抗氧(yang)(yang)化(hua)劑的(de)使用(yong)(yong)給人(ren)體健康造成的(de)隱患。

食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)裝罐完畢后(hou)向瓶(ping)(ping)中(zhong)充入氮(dan)(dan)(dan)氣(qi)(qi)(qi)(qi)(qi)(qi)，使(shi)(shi)(shi)(shi)瓶(ping)(ping)內(nei)的(de)(de)(de)(de)(de)(de)(de)(de)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)和(he)(he)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)內(nei)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)被(bei)置(zhi)換出來(lai)，然(ran)后(hou)壓(ya)蓋密封，這(zhe)樣(yang)一(yi)(yi)方(fang)(fang)面(mian)(mian)使(shi)(shi)(shi)(shi)得瓶(ping)(ping)內(nei)氧(yang)(yang)(yang)(yang)(yang)(yang)化(hua)(hua)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)殘留(liu)非常(chang)低，食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)沒(mei)(mei)有(you)可供(gong)反(fan)應的(de)(de)(de)(de)(de)(de)(de)(de)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)源；另一(yi)(yi)方(fang)(fang)面(mian)(mian)，氮(dan)(dan)(dan)氣(qi)(qi)(qi)(qi)(qi)(qi)在瓶(ping)(ping)的(de)(de)(de)(de)(de)(de)(de)(de)頂(ding)空(kong)(kong)(kong)(kong)部(bu)分(fen)形成(cheng)了氮(dan)(dan)(dan)封，阻隔了氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)與(yu)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)接(jie)(jie)觸，達(da)到(dao)了保(bao)(bao)護(hu)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)，防止食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)氧(yang)(yang)(yang)(yang)(yang)(yang)化(hua)(hua)的(de)(de)(de)(de)(de)(de)(de)(de)效果，同時(shi)可以(yi)避免(mian)人工抗氧(yang)(yang)(yang)(yang)(yang)(yang)化(hua)(hua)劑(ji)的(de)(de)(de)(de)(de)(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)給人體健(jian)康造成(cheng)的(de)(de)(de)(de)(de)(de)(de)(de)隱患(huan)。這(zhe)種(zhong)保(bao)(bao)鮮(xian)方(fang)(fang)式對于食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)本(ben)身(shen)的(de)(de)(de)(de)(de)(de)(de)(de)品(pin)質(zhi)是(shi)(shi)要(yao)求(qiu)非常(chang)高(gao)的(de)(de)(de)(de)(de)(de)(de)(de),而市場上食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)里面(mian)(mian),目(mu)前也只有(you)烏(wu)克(ke)蘭某牌等少數的(de)(de)(de)(de)(de)(de)(de)(de)品(pin)牌產品(pin)能(neng)(neng)達(da)到(dao)這(zhe)種(zhong)嚴苛的(de)(de)(de)(de)(de)(de)(de)(de)標(biao)(biao)準食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)裝罐完畢后(hou)向瓶(ping)(ping)中(zhong)充入氮(dan)(dan)(dan)氣(qi)(qi)(qi)(qi)(qi)(qi)，使(shi)(shi)(shi)(shi)瓶(ping)(ping)內(nei)的(de)(de)(de)(de)(de)(de)(de)(de)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)和(he)(he)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)內(nei)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)被(bei)置(zhi)換出來(lai)，然(ran)后(hou)壓(ya)蓋密封，這(zhe)樣(yang)一(yi)(yi)方(fang)(fang)面(mian)(mian)使(shi)(shi)(shi)(shi)得瓶(ping)(ping)內(nei)氧(yang)(yang)(yang)(yang)(yang)(yang)化(hua)(hua)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)殘留(liu)非常(chang)低，食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)沒(mei)(mei)有(you)可供(gong)反(fan)應的(de)(de)(de)(de)(de)(de)(de)(de)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)源；另一(yi)(yi)方(fang)(fang)面(mian)(mian)，氮(dan)(dan)(dan)氣(qi)(qi)(qi)(qi)(qi)(qi)在瓶(ping)(ping)的(de)(de)(de)(de)(de)(de)(de)(de)頂(ding)空(kong)(kong)(kong)(kong)部(bu)分(fen)形成(cheng)了氮(dan)(dan)(dan)封，阻隔了氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)與(yu)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)的(de)(de)(de)(de)(de)(de)(de)(de)接(jie)(jie)觸，達(da)到(dao)了保(bao)(bao)護(hu)食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)，防止食(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)油(you)(you)(you)(you)氧(yang)(yang)(yang)(yang)(yang)(yang)化(hua)(hua)的(de)(de)(de)(de)(de)(de)(de)(de)效果，同時(shi)可以(yi)避免(mian)人工抗氧(yang)(yang)(yang)(yang)(yang)(yang)化(hua)(hua)劑(ji)的(de)(de)(de)(de)(de)(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)給人體健(jian)康造成(cheng)的(de)(de)(de)(de)(de)(de)(de)(de)隱患(huan)。因為很多生(sheng)物(wu)的(de)(de)(de)(de)(de)(de)(de)(de)生(sheng)長(chang)(chang)都(dou)是(shi)(shi)需要(yao)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)(de)，充入氮(dan)(dan)(dan)氣(qi)(qi)(qi)(qi)(qi)(qi)后(hou)，可以(yi)排除(chu)(chu)袋中(zhong)的(de)(de)(de)(de)(de)(de)(de)(de)氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)，減(jian)(jian)慢氧(yang)(yang)(yang)(yang)(yang)(yang)化(hua)(hua)作用(yong)(yong)(yong)(yong)(yong)，減(jian)(jian)少了氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)生(sheng)存的(de)(de)(de)(de)(de)(de)(de)(de)基礎沒(mei)(mei)有(you)了，同時(shi)，氮(dan)(dan)(dan)氣(qi)(qi)(qi)(qi)(qi)(qi)是(shi)(shi)一(yi)(yi)種(zhong)很不活潑的(de)(de)(de)(de)(de)(de)(de)(de)物(wu)質(zhi)，在常(chang)溫、常(chang)壓(ya)下絕大(da)多數物(wu)質(zhi)都(do

三、如(ru)何快速(su)鑒別是“充氮保(bao)鮮(xian)"還是“無添加保(bao)鮮(xian)"？

當(dang)然這(zhe)兩(liang)種保鮮方法較明(ming)顯的不(bu)(bu)同點(dian)是(shi)體現(xian)在(zai)外(wai)(wai)包裝上面(mian),“充(chong)(chong)(chong)氮保鮮"會(hui)使食用油的瓶(ping)(ping)(ping)子(zi)(zi)看起來更好看,整個瓶(ping)(ping)(ping)子(zi)(zi)充(chong)(chong)(chong)盈飽滿,用手指按壓(ya)瓶(ping)(ping)(ping)身(shen),瓶(ping)(ping)(ping)子(zi)(zi)也(ye)壓(ya)不(bu)(bu)動(dong);“無(wu)添加保鮮"的食用油瓶(ping)(ping)(ping)子(zi)(zi)則會(hui)在(zai)按壓(ya)的時候(hou)出(chu)現(xian)凹陷。這(zhe)是(shi)因為瓶(ping)(ping)(ping)子(zi)(zi)里面(mian)沒有(you)空氣,屬于真空狀態(tai)。如果(guo)充(chong)(chong)(chong)氮氣后則會(hui)使瓶(ping)(ping)(ping)子(zi)(zi)內外(wai)(wai)氣壓(ya)均衡,不(bu)(bu)會(hui)出(chu)現(xian)這(zhe)種情況。

包裝食(shi)用(yong)油時(shi)若通過高濃(nong)度(du)氮(dan)氣(qi)(qi)以降低氧(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)濃(nong)度(du)，可減少食(shi)用(yong)植(zhi)物(wu)(wu)油與(yu)氧(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)接觸，從而(er)延(yan)緩氧(yang)(yang)(yang)(yang)(yang)化酸敗，也是抗氧(yang)(yang)(yang)(yang)(yang)化重要(yao)措施(shi)。因為很多生物(wu)(wu)的(de)(de)生長都(dou)是需要(yao)氧(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)的(de)(de)，充(chong)入氮(dan)氣(qi)(qi)后(hou)，可以排除(chu)袋中(zhong)的(de)(de)氧(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)，減慢氧(yang)(yang)(yang)(yang)(yang)化作用(yong)，減少了(le)氧(yang)(yang)(yang)(yang)(yang)氣(qi)(qi)生存的(de)(de)基礎沒有(you)了(le)，同時(shi)，氮(dan)氣(qi)(qi)是一種很不(bu)活潑的(de)(de)物(wu)(wu)質，在常溫、常壓下絕(jue)大多數物(wu)(wu)質都(dou)與(yu)它不(bu)會(hui)發生反應。
