style="font-size:16px;">食品防腐劑的種類</span> </h1> <p> <span style="font-size:16px;">按照來源，可將食品防腐劑分為化學(xué)防腐劑和天然防腐劑兩大類。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">1.1 酸型防腐劑 </span> </p> <p> <span style="font-size:16px;">常用的酸型防腐劑有苯甲酸、山梨酸和丙酸以及它們的鹽類等…。酸型防腐劑要在酸性條件下通過未解離的分子而起抑菌的作用，其防腐效果與pH 有關(guān)。酸型防腐劑之所以可以抑菌防腐，是由于其會(huì)干擾微生物的酶系統(tǒng)，使其不能行使正常代謝功能。同時(shí)酸型防腐劑對(duì)細(xì)胞膜的通透性有阻礙作用，會(huì)微生物的生長(zhǎng)與繁殖。</span> </p> <p> <span style="font-size:16px;">酸型防腐劑中的苯甲酸價(jià)格低廉，廣泛應(yīng)用于醬油和化妝品等日常生活用品中，但苯甲酸及其鹽類的毒性副作用一直備受爭(zhēng)議。山梨酸對(duì)霉菌、酵母菌有很強(qiáng)的作用，是公認(rèn)的高效低毒防腐劑，對(duì)食品風(fēng)味沒有影響，通常應(yīng)用于以面粉，荊州食用防腐劑價(jià)格、魚肉、蛋禽等為原料加工而成的食品中。</span> </p> <p> <span style="font-size:16px;"><span style="display:none;"></span>1.2 酯型防腐劑</span> </p> <p> <span style="font-size:16px;">酯型防腐劑是指尼泊金酯類，我國(guó)普遍使用的是對(duì)羥基苯甲酸、乙酯和丙酯等。酯型防腐劑的作用機(jī)理是破壞微生物的細(xì)胞膜，荊州食用防腐劑價(jià)格，使細(xì)胞內(nèi)的蛋白質(zhì)變性失活，從而破壞微生物的正常生理平衡，荊州食用防腐劑價(jià)格。酯型防腐劑主要應(yīng)用于蔬果保鮮，較酸型防腐劑殺菌效果更強(qiáng)，其防腐效果也不會(huì)因?yàn)樗釅A度的改變而改變，在胃腸道內(nèi)能迅速完全被吸收，并能水解成對(duì)羥基苯甲酸，而從尿中排出，不在體內(nèi)積蓄，因此毒性也比較低。</span>

style="font-size:16px;"></span><span style="font-size:16px;">山梨酸及其鉀鹽</span> </h1> <p> <span style="font-size:18px;">同苯甲酸及其鈉鹽類似，食品中常使用的防腐劑還有山梨酸鉀（CH3CH=CHCH=CHCOOK）, 山梨酸鉀能有效地霉菌，酵母菌和好氧性細(xì)菌的活性，從而延長(zhǎng)食品的保存時(shí)間，并保持原有食品的風(fēng)味。山梨酸（鉀）是一種不飽和脂肪酸（鹽），它可以被人體的代謝系統(tǒng)吸收而迅速分解為二氧化碳和水，在體內(nèi)無殘留，是國(guó)際上公認(rèn)的無害的食品防腐劑，防腐效果也明顯高于苯甲酸類，是苯甲酸鹽的5-10倍，因此其應(yīng)用也更。下表為GB2760-2014中規(guī)定的山梨酸及其鉀鹽的使用量</span> </p> <p> <span style="font-size:18px;">苯甲酸及其鈉鹽和山梨酸及其鉀鹽是食品防腐劑中常用的兩種，尤其是后者，在日本所用的防腐劑中山梨酸及山梨酸鉀已高達(dá)90％以上。此外常見的食品防腐劑還有丙酸鈣、脫氫乙酸、對(duì)羥基苯甲酸脂類等。防腐劑在食品工業(yè)中已被使用，人們大可不必談防腐劑色變，只要規(guī)范使用，含防腐劑的食品一樣可放心食用。而且，防腐劑可限制食品中細(xì)菌和微生物的滋長(zhǎng)，如可產(chǎn)生劇毒物質(zhì)肉的“肉毒菌”以及可產(chǎn)生強(qiáng)致物質(zhì)黃曲霉的“黃曲霉”等。</span><span

style="font-size:16px;">食品防腐劑是用于防止食品因微生物引起的變質(zhì)，提高食品保存性能，延長(zhǎng)食品保質(zhì)期而使用的食品添加劑。飲品中常用的防腐劑有山梨酸鉀，檸檬酸，乳酸，笨鉀酸鈉等。</span> </p> <p> <span style="font-size:16px;">那么，飲品中為什么要添加防腐劑，什么情況下飲品不需要添加防腐劑呢？我們就來聊一聊關(guān)于飲品防腐的那些影響因素。</span> </p> <p> <span style="font-size:16px;">由于飲品流動(dòng)性及傳熱性較好，采用管式或者板式密閉殺菌機(jī)UHT殺菌（超高溫瞬時(shí)滅菌工藝），均能殺滅產(chǎn)品中的常規(guī)微生物。中性飲品（pH>4.6）通常采用135-140℃×4-10秒滅菌，酸性飲品（pH<4.6）通常采用105-121℃×5-15秒滅菌。但因?yàn)闅⒕蟮陌b材料和生產(chǎn)工藝不同，有的飲品必須使用防腐劑，有的完全不需要防腐劑。</span> </p> <p> <span style="font-size:16px;"> 碳酸飲料糖漿殺菌后，方能混入二氧化碳?；旌霞肮嘌b過程中，均存在微生物污染風(fēng)險(xiǎn)，所以幾乎所有的碳酸飲料均含防腐劑。其他非碳酸飲料，有的廠商為降低包材和設(shè)備成本，在非無菌灌裝環(huán)境灌裝，采用非耐熱包裝，如不耐熱塑料瓶（輕質(zhì)量）、非蒸煮型塑料袋，因此必須添加防腐劑。</span> </p> <p> <br /> </p><h1> <span style="font-size:16px;">防腐劑是什么?</span> </h1> <p> <br /> </p> <p> <span style="font-size:16px;">食品含有豐富的營(yíng)養(yǎng)物質(zhì)，這些物質(zhì)可以給人體提供能量和豐富的營(yíng)養(yǎng)素，但也容易被微生物污染，因此，一旦少量微生物侵染了食品，在短時(shí)間內(nèi)就可能在食品中迅速生長(zhǎng)繁殖，某些細(xì)菌和還可以產(chǎn)生大量的，引起食品變質(zhì)和食物中毒的發(fā)生。這就是食品中添加防腐劑的原因。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">“食品中添加防腐劑的主要作用是微生物的生長(zhǎng)和繁殖，延長(zhǎng)食品的保存時(shí)間?！北本┕ど檀髮W(xué)食品學(xué)院教授王靜解釋說，防腐劑可分為化學(xué)防腐劑和天然防腐劑。其中化學(xué)防腐劑又以“有機(jī)”和“無機(jī)”來具體劃分。苯甲酸及其鹽類、山梨酸及其鹽類、對(duì)羥基苯甲酸及其酯類等屬于“有機(jī)”類別。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則屬于“無機(jī)”類別。而天然防腐劑通常是從動(dòng)植物和微生物的代謝產(chǎn)物中提取，如乳酸鏈球菌素是從乳酸鏈球菌的代謝產(chǎn)物中提取得到的一種多肽物質(zhì)。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">她說，我國(guó)食品安全國(guó)家標(biāo)準(zhǔn)對(duì)食品防腐劑使用范圍、使用量均有嚴(yán)格的規(guī)定，且都經(jīng)過了大量的科學(xué)實(shí)驗(yàn)，證實(shí)允許使用的食品防腐劑對(duì)人體不會(huì)產(chǎn)生急性、亞急性或慢性危害，但如果食品中超量、超范圍使用防腐劑就會(huì)對(duì)消費(fèi)者的身體健康造成一定損害。</span>

<span style="font-size:16px;">防腐劑是指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。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">防腐劑安全嗎？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">在不超過安全劑量的情況下，防腐劑對(duì)人體是無害的。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">我國(guó)對(duì)防腐劑的使用有著非常嚴(yán)格的規(guī)定，防腐劑必須符合下列標(biāo)準(zhǔn)：</span> </p> <p> <span style="font-size:16px;">1.合理的使用對(duì)人體無害；</span> </p> <p> <span style="font-size:16px;">2.不會(huì)影響消化道菌群；</span> </p> <p> <span style="font-size:16px;">3.在消化道內(nèi)可以降解為食物的正常成分；</span> </p> <p> <span style="font-size:16px;">4.不會(huì)影響素的使用；</span> </p> <p> <span style="font-size:16px;">5.對(duì)食品熱處理時(shí)不會(huì)產(chǎn)生有害成分。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">我國(guó)批準(zhǔn)使用的食品防腐劑，在被批準(zhǔn)使用前經(jīng)過了大量嚴(yán)謹(jǐn)?shù)目茖W(xué)實(shí)驗(yàn)，有動(dòng)物飼養(yǎng)、毒性毒理試驗(yàn)和鑒定，同時(shí)國(guó)家也出臺(tái)了一系列法規(guī)和標(biāo)準(zhǔn)對(duì)食品防腐劑品種、數(shù)量和范圍進(jìn)行嚴(yán)格的控制。</span> </p> <p> <span style="font-size:16px;">除此之外，很多食品本身不含防腐劑，如罐頭食品，含鹽和糖極高的食品，還有一些水分含量較低的食品如方便面、掛面等。罐頭進(jìn)行灌裝時(shí)，會(huì)將其中的細(xì)菌和芽孢徹底殺滅，之后進(jìn)行密封，隔絕外面的細(xì)菌，所以它不需要防腐劑；大量的鹽和糖起到防腐劑的作用，細(xì)菌在沒有水的環(huán)境下無法繁殖。</span>
