style="font-size:16px;">顧名思義，食品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。食品防腐劑應(yīng)具備幾個特征：首先是性質(zhì)穩(wěn)定，在一定的時間內(nèi)有效；其次使用過程中或分解后無毒，河南食品防腐劑，不阻礙胃腸道酶類的正常作用，也不影響腸道正常菌群的活動；再者，在較低濃度下有抑菌或殺菌作用；，其本身無刺激味和異味，使用方便等。</span> </p> <p> <span style="font-size:16px;">二、食品防腐劑的種類</span> </p> <p> <span style="font-size:16px;">《食品安全國家標準食品添加劑使用標準》（GB 2760-2014）允許在食品中添加的防腐劑共有27種。按其來源可分為天然防腐劑和合成防腐劑，其中以合成防腐劑的商業(yè)化應(yīng)用廣。按照化學成分可分為有機防腐劑（如苯甲酸及其鹽類、山梨酸及其鹽類、對羥基苯甲酸及其酯類、乳酸等）和無機防腐劑（如亞硫酸及其鹽類、二氧化碳、亞硝酸鹽類、游離氯及次氯酸鹽等）。</span> </p> <p> <span style="font-size:16px;">不同防腐劑，或者同一種防腐劑的不同濃度，河南食品防腐劑，在應(yīng)用于不同的食品，或者針對不同的微生物種類等時，河南食品防腐劑，其產(chǎn)生的作用和效果并不一樣。因此，不同食品在加工制造、儲存運輸中需要使用不同的防腐劑。人們發(fā)現(xiàn)常規(guī)的熱殺菌技術(shù)與防腐劑組合使用，可以有效避免古法保藏和罐藏的缺陷。</span>

</p> <p> <span style="font-size:16px;">五是使用方便。</span> </p> <p> <span style="font-size:16px;">我國允許使用的防腐劑都是經(jīng)過嚴格的安全評估和程序?qū)徟?，與世界大部分國家同步的。防腐劑是否危害健康，常用的一個評判標準就是其毒性和攝入量，不但食品添加劑如此，所有的有毒物質(zhì)均如此。因此，在規(guī)定的添加量范圍內(nèi)使用，任何一種食品添加劑都是安全的，不會造成危害健康的問題。</span> </p> <p> <span style="font-size:16px;">人們普遍關(guān)心的另一問題是認為防腐劑不一定本身有毒，而是它增加肝臟、腎臟負擔。從已有科學試驗資料表明，防腐劑中的山梨酸鉀代謝方式與脂肪類似，不會增加肝臟負擔。硝酸鹽可還原成亞硝酸鹽，后者便變成一氧化氮排出，當然，一旦超過規(guī)定量就可以在胃中形成致物N—亞硝基化合物。</span> </p> <p> <br /> </p>

style="font-size:16px;">實際上，人類很早就開始利用防腐劑保存食物。比如，古時人們用鹽將蔬菜腌制后保存，以在寒冷的冬天也能吃到蔬菜，這里起到防腐作用的就是鹽。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">食品中使用防腐劑的主要目的其實是為了防止食品有微生物的“侵犯”，避免可能對人產(chǎn)生的危害，同時延長食物的保存期。王靜表示，如果食品受到有害微生物的污染，一旦產(chǎn)生，后果不堪設(shè)想。例如，在香腸、肉腸等加工肉制品中，可能存在一種“肉毒菌”的細菌，它產(chǎn)生的“肉”毒性極大;在發(fā)霉的花生制品中，則可能存在“黃曲霉”，它產(chǎn)生的“黃曲霉”的毒性也非常強，而且還有強烈的致性。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">與微生物污染可能帶來的危害相比，防腐劑對人的危害極小。目前，國家標準規(guī)定允許在食品中使用的防腐劑有30多種。比如，醬油中一般會加入防腐劑苯甲酸鈉，否則很容易滋生霉菌;面包和豆制品中常常添加的防腐劑是丙酸鈣或丙酸鈉，可以保證面包在一周內(nèi)不長霉菌;醬菜、果醬、調(diào)味品和飲料中往往加入山梨酸鉀或其他山梨酸鹽;葡萄酒等果酒中會加亞硫酸鹽等等。這些防腐劑都是經(jīng)過各國科學家反復(fù)驗證后才允許使用的，并且都有嚴格的限量，合理使用這些防腐劑并不會給健康造成危害。</span>
