<p> <br /> </p> <p> <span style="font-size:16px;">“人們制作金華火腿、宣威火腿，必須使用亞硝酸鹽作為防腐劑?！比涨?，中國工程院院士、北京工商大學(xué)校長孫寶國在接受千龍網(wǎng)記者采訪時(shí)解釋說，對(duì)于很多食品而言，不進(jìn)行“防腐”就很難長時(shí)間保存。例如，如果不使用亞硝酸鹽作為防腐劑，火腿上會(huì)生成肉毒桿菌等多種細(xì)菌，輕則會(huì)引起人食物中毒，重則危及人的生命。</span> </p> <p> <span style="font-size:16px;">孫寶國院士表示，目前亞硝酸鹽作為一種食品防腐劑，是國際上公認(rèn)的、安全的防腐劑。防腐劑是指一類加入食品中能防止或延緩食品的食品添加劑，其本質(zhì)是具有微生物增殖或殺死微生物的一類化合物，又稱為保藏劑。使用過程中或分解后無毒，一般都不會(huì)損害人體健康。</span> </p> <p> <span style="font-size:16px;">防腐劑的來源主要有天然和合成兩類，以合成的商業(yè)化應(yīng)用多。我國的GB2760—2011列出防腐劑共有27種，化學(xué)防腐劑包括有機(jī)的和無機(jī)的，有機(jī)的防腐劑主要是苯甲酸及其鹽類、山梨酸及其鹽類、對(duì)羥基苯甲酸及其酸類、乳酸等。</span> </p> <p> <span

<span style="font-size:16px;">目前使用的大多數(shù)防腐劑對(duì)人體都有一定的毒性，一旦過量會(huì)對(duì)健康產(chǎn)生危害。因此，各個(gè)國家對(duì)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(cè)對(duì)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(cè)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(cè)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(cè)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(cè)定，得到各種組分的回歸方程及相關(guān)系數(shù)。</span> </p>

style="font-size:16px;"></span> </h1> <p> <span style="font-size:16px;">苯甲酸及其鹽類防腐劑為結(jié)晶狀粉末或白色顆粒，無臭，微帶安息香氣味。苯甲酸及其鹽是食品工業(yè)中常見的一種防腐保鮮劑。其防腐機(jī)理是苯甲酸類防腐劑具有脂溶性強(qiáng)的特點(diǎn)，容易通過細(xì)胞膜進(jìn)入細(xì)胞體內(nèi)，導(dǎo)致微生物細(xì)胞膜的通透性**擾，細(xì)胞膜對(duì)相關(guān)氨基酸的吸收被有效，苯甲酸分子是以酸化細(xì)胞體內(nèi)儲(chǔ)堿的方式使細(xì)胞的呼吸酶系失去活性，從而對(duì)食品起到防腐保鮮的作用。</span> </p> <p> <span style="font-size:16px;">安全性：一般情況下，苯甲酸被認(rèn)為是安全的，在食品中添加少量苯甲酸時(shí)，對(duì)人體并無。人體攝入少量的苯甲酸后，苯甲酸與體內(nèi)的一種氨基酸生成一種無害的新物質(zhì)，隨尿液排出。</span>

style="font-size:16px;">飲料中常見防腐劑 </span> </h1> <p> <span style="font-size:16px;"> 苯甲酸又名安息香酸，稍溶于水，溶于乙醇，酸性條件下對(duì)多種微生物（酵母、霉菌、細(xì)菌）有明顯抑菌作用，對(duì)產(chǎn)酸菌作用較弱。在直接飲用的飲料內(nèi)的大使用量為0.2克/ 公斤。因?yàn)楸郊姿崛芙舛鹊?，使用不便，?shí)際生產(chǎn)中大多是使用其鈉鹽，其鈉鹽的作用是轉(zhuǎn)化為苯甲酸后起作用的。</span> </p> <p> <span style="font-size:16px;"> 山梨酸，又名花楸酸，微溶于水，易溶于乙醇。對(duì)光、對(duì)熱穩(wěn)定，長期放置易被氧化著色。對(duì)霉菌、酵母菌和好氣性細(xì)菌均有抑菌作用。山梨酸是酸性防腐劑，適用范圍在pH 值5.5以下，而毒性為苯甲酸的1/4，所以從國外發(fā)展動(dòng)向看，有逐步取代苯甲酸及其鈉鹽的趨勢(shì)。大使用量:0.6克/公斤。食品防腐劑的檢測(cè)方法目前使用的大多數(shù)防腐劑對(duì)人體都有一定的毒性，一旦過量會(huì)對(duì)健康產(chǎn)生危害。因此，各個(gè)國家對(duì)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(cè)對(duì)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(cè)主要有液相色譜法、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、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(cè)方法。</span> 遼寧食用防腐劑廠家</p><p
