真(zhen)空袋(dai)主(zhu)(zhu)要作用是(shi)(shi)除氧(yang)(yang),以有利于防止食(shi)(shi)品(pin)變質,其(qi)原理也(ye)比較簡單(dan),因食(shi)(shi)品(pin)霉(mei)(mei)腐變質主(zhu)(zhu)要由微(wei)生(sheng)(sheng)(sheng)物(wu)的(de)(de)活動(dong)造成,而大(da)多(duo)數微(wei)生(sheng)(sheng)(sheng)物(wu)(如霉(mei)(mei)菌和酵母菌)的(de)(de)生(sheng)(sheng)(sheng)存是(shi)(shi)需要氧(yang)(yang)氣(qi)(qi)(qi)的(de)(de),而真(zhen)空包裝(zhuang)就(jiu)是(shi)(shi)運(yun)用這(zhe)個原理,把(ba)包裝(zhuang)袋(dai)內和食(shi)(shi)品(pin)細(xi)胞內的(de)(de)氧(yang)(yang)氣(qi)(qi)(qi)抽掉(diao),使微(wei)物(wu)物(wu)失去“生(sheng)(sheng)(sheng)存的(de)(de)環境”。實驗證明:當包裝(zhuang)袋(dai)內的(de)(de)氧(yang)(yang)氣(qi)(qi)(qi)濃度≤1%時(shi),微(wei)生(sheng)(sheng)(sheng)物(wu)的(de)(de)生(sheng)(sheng)(sheng)長和繁殖(zhi)速(su)度就(jiu)急劇下降,氧(yang)(yang)氣(qi)(qi)(qi)濃度≤0.5%時(shi),大(da)多(duo)數微(wei)生(sheng)(sheng)(sheng)物(wu)將受到(dao)抑制而停止繁殖(zhi)。
