style="font-size:16px;">雖然名字很是復(fù)雜，這些入選的防腐劑可不簡(jiǎn)單，桂林防腐劑經(jīng)銷商，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？?jī)蓚€(gè)意思：</span> </p> <p> <span

</p> <p> <br /> </p> <p> <br /> </p> <p> <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:18px;"></span> </p><h1> <span style="font-size:16px;">山梨酸及其鹽防腐劑的作用機(jī)理和安全性</span> </h1> <p> <span style="font-size:16px;">山梨酸為無色針狀結(jié)晶或白色結(jié)晶粉末，略有特殊氣味，升華。山梨酸鉀是白色至微黃色鱗片狀結(jié)晶或粉末，作為食品防腐劑一般加工成小圓柱型。山梨酸是酸性防腐劑，其防腐機(jī)理是穿透細(xì)胞壁，進(jìn)入細(xì)胞體內(nèi)，微生物體內(nèi)的脫氫酶系統(tǒng)，導(dǎo)致其喪失活性，微生物的生長(zhǎng)繁殖，從而起到對(duì)食品防腐保鮮的作用。</span> </p> <p> <span style="font-size:16px;">安全性：梨酸可參與人體內(nèi)的正常代謝，并終被氧化為二氧化碳和水，對(duì)人體基本無害，且對(duì)食品風(fēng)味也無不良影響，是國(guó)際糧農(nóng)組織和衛(wèi)生組織推薦的高效安全的防腐保鮮劑，已被所有國(guó)家和地區(qū)允許使用。</span>

style="font-size:16px;">現(xiàn)如今，隨著經(jīng)濟(jì)的不斷發(fā)展，人們的生活水平也在不斷提高，人們對(duì)吃、穿、住的要求也發(fā)生了深刻的變化，與之相適應(yīng)，各式各樣的食品琳瑯滿目地呈現(xiàn)在了食品超市的柜臺(tái)上，各種品牌服裝出現(xiàn)在了小小的商場(chǎng)里，豪華的家具與新型的裝飾材料在新的住宅里也悄悄地在更新?lián)Q代?，F(xiàn)在，我們先從吃的方面——食品防腐劑與健康，來談一談這些話題。</span> </p> <p> <span style="font-size:16px;">食品防腐劑是防止因微生物的作用引起食品變質(zhì)，延長(zhǎng)食品保存期的一種食品添加劑，它還有防止食物中毒的作用。因此，加工的食品絕大多數(shù)有防腐劑。防腐劑分為無機(jī)防腐劑和有機(jī)防腐劑兩大類。其中，無機(jī)防腐劑有亞硫酸鹽、焦亞硫酸鹽及二氧化硫等。但由于使用二氧化硫、亞硫酸鹽后殘存的SO2能引起嚴(yán)重的過敏反應(yīng)（主要是呼吸道過敏），故FAO于1986年禁止在新鮮果蔬中使用無機(jī)防腐劑。</span><span

<span 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、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，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，而從尿中排出，不在體內(nèi)積蓄，因此毒性也比較低。</span>
