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、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，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。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，湖北食用防腐劑經(jīng)銷商，湖北食用防腐劑經(jīng)銷商，而從尿中排出，不在體內(nèi)積蓄，湖北食用防腐劑經(jīng)銷商，因此毒性也比較低。</span>

</h1> <p> <br /> </p> <p> <span style="font-size:16px;">丙酸及其鹽類是近年來發(fā)展起來的一種新型食品防腐劑，常用用于面包、糕點(diǎn)等食品及飲料的防霉保鮮。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">安全性：對(duì)人體無毒副作用，而且能經(jīng)人體新陳代謝排出，安全性高。</span> </p> <p> <span style="font-size:16px;">山梨酸及其鹽</span> </p> <p> <span style="font-size:16px;">山梨酸也叫花秋酸，是目前為主流的食品用防腐劑。山梨酸對(duì)霉菌、酵母菌和好氣性細(xì)菌均有作用，并可參與機(jī)體的正常代謝，是迄今為止國際公認(rèn)的防腐劑之一。</span> </p> <p> <span style="font-size:16px;">脫氫醋酸及其鹽</span> </p> <p> <span style="font-size:16px;">脫氫醋酸屬于廣譜防腐劑，能有效霉菌和酵母菌的繁殖，從而起到延長保質(zhì)期的作用，常被添加于奶油、湯料、糕點(diǎn)、面包、醬油、醬菜、果汁、腐乳、米面制品、魚肉制品、糧食等產(chǎn)品中。</span> </p> <p> <span style="font-size:16px;">苯甲酸及其鹽</span> </p> <p> <span style="font-size:16px;">苯甲酸又名安息香酸，在酸性條件下對(duì)酵母、霉菌、細(xì)菌等有明顯的作用，在實(shí)際生活中常能見到其鈉鹽——苯甲酸鈉，被添加于碳酸飲料、低鹽醬菜、蜜餞、醬油、醋等食品中。</span> </p> <p> <span style="font-size:16px;">尼泊金酯</span> </p> <p> <span style="font-size:16px;">尼泊金酯又稱對(duì)羥基苯甲酸酯類，其對(duì)霉菌、酵母菌有作用，可在果汁、果醬及飲料中看到該成分。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">此外，瓊脂低聚糖、兒茶素、蜂膠黃酮防腐抗氧化劑、殼聚糖等源自自然的防腐劑也有后來居上的意思。</span> 江蘇防腐劑供應(yīng)商食品級(jí)防腐劑生產(chǎn)廠家，食品防腐劑現(xiàn)貨供應(yīng)湖北福潤德食品原料有限公司。</p><div style="width:100%;text-align: center;"><img

style="font-size:16px;">食品添加劑——防腐劑</span> </h1> <p> <br /> </p> <p> <span style="font-size:16px;"> 根據(jù)我國食品衛(wèi)生法的規(guī)定，食品添加劑是為改善食品色、香、味等品質(zhì)，以及為防腐和加工工藝的需要而加入食品中的人工合成或者天然物質(zhì)。目前我國食品添加劑有23個(gè)類別，2000多個(gè)品種，包括酸度調(diào)節(jié)劑、抗結(jié)劑、消泡劑、抗氧化劑、漂白劑、膨松劑、著色劑、護(hù)色劑、酶制劑、增味劑、營養(yǎng)強(qiáng)化劑、防腐劑、甜味劑、增稠劑、香料等。</span> </p> <p> <span style="font-size:16px;"> </span> </p> <p> <span style="font-size:16px;"> 小編和大家聊一下防腐劑，現(xiàn)在一般市面上的所有食品產(chǎn)品都離不開防腐劑，使用防腐劑的目的就是防止食物變質(zhì)。</span> </p> <p> <span style="font-size:16px;"> </span> </p> <p> <span style="font-size:16px;"> 談到防腐劑，人們往往認(rèn)為有害，其實(shí)在安全使用范圍內(nèi)，對(duì)人體是無毒副作用的。我**腐劑使用有嚴(yán)格的規(guī)定，防腐劑應(yīng)符合以下標(biāo)準(zhǔn)：</span> </p> <p> <span style="font-size:16px;">1、合理使用對(duì)人體無害；</span> </p> <p> <span style="font-size:16px;">2、不影響消化道菌群；</span> </p> <p> <span style="font-size:16px;">3、在消化道內(nèi)可降解為食物的正常成分；</span> </p> <p> <span style="font-size:16px;">4、不影響素的使用；</span> </p> <p> <span style="font-size:16px;">5、對(duì)食品熱處理時(shí)不產(chǎn)生有害成分。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;"> </span> </p> <p> <br /> </p><h1> <span style="font-size:16px;">1.什么是防腐劑？</span> </h1> <p> <span style="font-size:16px;">防腐劑，看名字就知道，是指防止食品變質(zhì)的物質(zhì)，好處是讓食品放久一點(diǎn)。</span> </p> <p> <span style="font-size:16px;">在我們國家，能夠用到食品中的防腐劑有三十多種，舉幾個(gè)例子：</span> </p> <p> <span style="font-size:16px;">苯甲酸及其鈉鹽（苯甲酸鈉）、山梨酸及其鉀鹽（山梨酸鉀）、脫氫乙酸及其鈉鹽等等[1]。</span> </p> <p> <span style="font-size:16px;">雖然名字很是復(fù)雜，這些入選的防腐劑可不簡單，它們都是經(jīng)過嚴(yán)格的風(fēng)險(xiǎn)評(píng)估，證實(shí)可以安全使用的，而且還被嚴(yán)格規(guī)定了它們的使用范圍、使用量或殘留量[2]。</span> </p> <h1> <span style="font-size:16px;">2.防腐劑有害？</span> </h1> <p> <span style="font-size:16px;">說到這里，可能有些朋友就會(huì)說了，再怎么樣，化學(xué)合成的東西就是不好。</span> </p> <p> <span style="font-size:16px;">不得不承認(rèn)的是，防腐劑大多是人工合成的，如果超標(biāo)準(zhǔn)使用，的確會(huì)對(duì)人體造成一定的損害。</span> </p> <p> <span style="font-size:16px;">“超標(biāo)準(zhǔn)”是啥意思？兩個(gè)意思：</span> </p> <p> <span style="font-size:16px;">一是超限量；</span> </p> <p> <span style="font-size:16px;">二是超范圍。</span> </p> <p> <span style="font-size:16px;">例如，某品牌山楂條，苯甲酸及其鈉鹽（以苯甲酸計(jì)）檢出值為0.669g/kg，比國家標(biāo)準(zhǔn)規(guī)定（不超過0.5g/kg）高出33.8%，這就屬于超限量使用[3]。</span> </p> <p> <span style="font-size:16px;">又如，某品牌辣子雞丁（屬于醬鹵肉制品）中檢測出含有苯甲酸及其鈉鹽（以苯甲酸計(jì)），而國家規(guī)定醬鹵肉制品中不得使用苯甲酸及其鈉鹽，這就屬于超范圍使用[4]。</span> </p> <p> <span style="font-size:16px;">相反，如果是按照國家規(guī)定合理使用防腐劑的，就不需要擔(dān)心安全性問題了。</span> </p> <p> <br /> 防腐劑工廠，食品防腐劑現(xiàn)貨供應(yīng)湖北福潤德食品原料有限公司。</p><div style="width:100%;text-align: center;"><img

對(duì)新鮮食品的需求不斷增長，已導(dǎo)致食品制造商面臨食品安全和質(zhì)量方面的挑戰(zhàn)，食品添加劑“魚與熊掌”能兼得嗎？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">人工防腐劑能在更長的時(shí)間內(nèi)保持新鮮感，但這些防腐劑中有些是對(duì)人體有害的，有些還有致作用。硝酸鈉是一種防腐劑，用于火腿、香腸和熏肉等，主要用來控制肉毒桿菌，但亞硝酸鈉可以與蛋白質(zhì)發(fā)生反應(yīng)，或者在高溫加熱的過程中，形成致的亞硝胺，而亞硝胺具有致作用。常用的苯甲酸鈉可以將瓶裝番茄醬的保質(zhì)期延長至40周而沒有質(zhì)量損失，然而，當(dāng)與維生素C結(jié)合時(shí)，它就能形成致的苯。另外，對(duì)苯甲酸鈉的攝入也可能導(dǎo)致多動(dòng)癥。</span> </p> <p> <span style="font-size:16px;">防腐劑用于延長食品的保質(zhì)期，并延長食品的保質(zhì)期。如果我們必須使用食品防腐劑,我們應(yīng)該盡量食用那些對(duì)我們影響小，通常被認(rèn)為是安全的防腐劑。對(duì)于那些通常不認(rèn)為安全的防腐劑,不應(yīng)該超過ADIs（可接受的每日攝入量）。為了盡量減少由于食品添加劑和防腐劑造成的健康問題的風(fēng)險(xiǎn)，應(yīng)該盡量避免食用含有這些添加劑和防腐劑的食品，在購買食品前，應(yīng)檢查其成分，或許不含人工添加劑和防腐劑的有機(jī)食品能為當(dāng)代人提供一中備用選擇吧。</span>

<span style="font-size:16px;">食品防腐劑知多少</span> </h1> <p> <br /> </p> <p> <span style="font-size:16px;">自古以來，人們就有食品防腐的意識(shí)：古人把肉曬成肉干、做成臘肉；把蔬菜用鹽腌制、置于地窖存放；把水果曬干、做成蜜餞果脯等等。在現(xiàn)代食品工業(yè)中，得益于技術(shù)提升和科技進(jìn)步，食品防腐有了更高效的手段：添加防腐劑。適量防腐劑的添加可以有效各種有害微生物，起到阻止、延緩食品的變質(zhì)，甚至提高食品品質(zhì)的作用。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">但消費(fèi)者對(duì)防腐劑的認(rèn)知，在一定程度上，還存在滯后性。現(xiàn)對(duì)食品的原因、什么是食品防腐劑、防腐劑的安全性等進(jìn)行簡單介紹。</span> </p> <span style="font-size:16px;"></span> <p>
