style="font-size:16px;">目前使用的大多數(shù)防腐劑對人體都有一定的毒性，一旦過量會對健康產(chǎn)生危害。因此，各個國家對防腐劑的用量和殘留量都有嚴(yán)格的規(guī)定，防腐劑的準(zhǔn)確檢測對食品衛(wèi)生安全具有重要意義。</span> </p> <p> <span style="font-size:16px;">目前食品防腐劑的檢測主要有高效液相色譜法、氣相色譜法、紫外光分光光度法、薄層色譜法，滴定法等。其中氣相色譜法、高效液相色譜法、紫外光分光光度法準(zhǔn)確度高，分析快捷，是目前常用的檢測方法。</span> </p> <p> <span style="font-size:16px;">01高效液相色譜法原理：</span> </p> <p> <span style="font-size:16px;">配制苯甲酸鈉、山梨酸鉀和安賽蜜的標(biāo)準(zhǔn)溶液，以230nm為檢測波長，繪制標(biāo)準(zhǔn)曲線；樣品經(jīng)超聲波脫氣、膜過濾后直接進(jìn)樣，按上述條件進(jìn)行色譜測定，得到各種組分的回歸方程及相關(guān)系數(shù)。</span> </p> <p> <span style="font-size:16px;">02紫外分光光度法原理：</span> </p> <p> <span style="font-size:16px;">利用苯甲酸鈉和山梨酸鉀的紫外吸收光譜差異, 采用多元線性回歸紫外吸光光度法同時測定飲料中苯甲酸鈉和山梨酸鉀。其中樣品無需預(yù)處理。</span> </p> <p> <br /> </p> <p> <br />

style="font-size:16px;">**：無論是防腐劑還是食品添加劑，都不能離開“量”來說事。在相同的食用量下，常用的防腐劑丙酸鈣毒性與食鹽相當(dāng)。而現(xiàn)在被使用的山梨酸鉀，毒性更是只有食鹽的1/2。</span> </p> <p> <span style="font-size:16px;">比如，允許在包裝醬菜中使用的山梨酸鉀，每千克包裝醬菜中的使用量為500毫克，按照一個成年人50千克的體重，每天允許攝入1250毫克山梨酸鉀來計(jì)算，即每天要吃2.5千克按照國家標(biāo)準(zhǔn)生產(chǎn)的包裝醬菜才能達(dá)到這個量。我們在日常生活中不可能每天吃那么多醬菜，所以不用擔(dān)心防腐劑攝入過量的問題。 </span><span style="font-size:16px;"></span> </p><h1> <span style="font-size:16px;">不要被“不添加防腐劑”所迷惑</span> </h1> <p> <span style="font-size:16px;">按照《食品安全國家標(biāo)準(zhǔn)食品添加劑使用標(biāo)準(zhǔn)》（GB 2760-2014）規(guī)定，防腐劑有明確的使用范圍和限量。并不是所有的食品都需要使用防腐劑，如罐頭、食鹽等食品，其加工工藝或本身性質(zhì)可以保障該食品在儲存期內(nèi)不會因微生物繁殖而變質(zhì)，并不需要使用防腐劑來保質(zhì)。而有些食品因生產(chǎn)工藝的需要，在生產(chǎn)過程中則需要使用防腐劑來或殺死微生物，以保證食品的安全食用。因此，消費(fèi)者在購買食品時，要理性看待食品標(biāo)簽，科學(xué)辨識；不要迷信于某些標(biāo)簽上聲稱的“不添加防腐劑”或“不使用防腐劑”等字樣。</span>

style="font-size:16px;">I類防腐劑是常見的鹽、糖、葡萄糖、葡萄糖、香料醋或醋酸、蜂蜜、可食用植物油；</span> </p> <p> <span style="font-size:16px;">II類防腐劑是苯甲酸，硝酸鹽或亞硝酸鈉或鉀鹽等，其在火腿中為常見。苯甲酸鈉主要用于果汁、腌菜和軟飲料，以防止酸性食物中的微生物生長；苯甲酸主要用于果汁、碳酸飲料和泡菜；二氧化硫和亞硫酸鹽可以霉菌和細(xì)菌，也可以細(xì)菌的產(chǎn)生，可以用來控制不受歡迎的細(xì)菌和野生酵母，而不會影響到二氧化硫耐受培養(yǎng)的酵母；氯化鈉作為防腐劑，已經(jīng)被使用了幾個世紀(jì)，以防止食物的變質(zhì)，鹽的活性與它降低水活性的能力有關(guān)，從而影響微生物的生長；乳酸鏈球菌素主要用于革蘭氏陽性菌的生長；食物酸可以使味道更“鋒利”，同時也起到防腐劑和抗氧化劑的作用。常見的食物酸包括醋、檸檬酸、酒石酸、蘋果酸、富馬酸和乳酸。山梨酸和山梨酸鹽對酵母和霉菌有效，山梨酸鹽可以在葡萄酒、果汁、干果、白干酪、肉類和魚類產(chǎn)品中酵母菌的生長；在可樂軟飲料中使用磷酸來降低pH值。醋酸用于蛋黃醬和沙拉醬中，類似的功能還有檸檬酸、酒石酸、蘋果酸和乳酸；直鏈羧酸、丙酸和酸二酸，主要利用它們的性能；丙酸主要利用抗的特性。</span>

style="font-size:16px;">1、超標(biāo)、超范圍使用：某些廠商為了迎合某些消費(fèi)者認(rèn)為保質(zhì)期越長，食品質(zhì)量越好的錯誤認(rèn)識，在食品加工時超標(biāo)準(zhǔn)大量使用；某些企業(yè)在往食品中添加防腐劑時，并未考慮原料中已添加的防腐劑的量造成超標(biāo)；國家衛(wèi)生標(biāo)準(zhǔn)中對防腐劑的使用范圍作了詳細(xì)的規(guī)定，某些生產(chǎn)企業(yè)擅自擴(kuò)大使用范圍。</span> </p> <p> <span style="font-size:16px;">2、違規(guī)使用：某商家為使食品保持新鮮的感官性狀，置消費(fèi)者健康不顧，使用國家明令禁止使用于食品的防腐劑。如福爾馬林浸泡海菜、魷魚、海參、豬肚(牛肚)等，嚴(yán)重影響消費(fèi)者身體健康。</span> </p> <p> <span style="font-size:16px;">3、過分夸大食品防腐劑的作用：食品防腐劑是在一個相當(dāng)長的時間段控制微生物生長，并不能殺死微生物，不少生產(chǎn)者對此認(rèn)識不清，而把防腐劑混同于消毒劑、殺菌劑，從而忽視在其他方面的消毒，造成產(chǎn)品中微生物指標(biāo)超標(biāo)；有些廠家在食品生產(chǎn)過程本身即存在嚴(yán)重衛(wèi)生問題，卻把防腐劑視為藥用于食品防腐保鮮；</span> </p> <p> <span style="font-size:16px;">4、使用劣質(zhì)防腐劑：為降低食品生產(chǎn)成本，使用質(zhì)次、價廉毒副作用大的劣質(zhì)防腐劑，只顧自家利益而損害消費(fèi)者健康權(quán)益。</span> 江門食品防腐劑報(bào)價</p><p
