style="font-size:16px;">是由生物體分泌或者體內(nèi)存在的具有抑菌作用的物質(zhì)，經(jīng)人工提取或者加工而成為食品防腐劑。不同于人工合成的防腐劑，此類防腐劑為天然物質(zhì)，有的本身就是食品的組分，如溶菌酶、乳酸鏈球菌素、納他霉素、殼聚糖、精蛋白等。</span> </p> <p> <br /> </p> <p> <span

style="font-size:16px;">乳酸鏈球菌素</span> </h1> <p> <span style="font-size:16px;">乳酸鏈球菌素的防腐機(jī)理是利用對細(xì)胞膜的干擾功能，使菌、致病菌。其對革蘭氏陽性菌、李斯特菌、溶血性鏈球菌等多種細(xì)菌引起的食品變質(zhì)有作用。</span> </p> <p> <span style="font-size:16px;">安全性：乳酸鏈球菌素是世界公認(rèn)安全的天然食品防腐劑，在人體內(nèi)終被降解為可被消化吸收的營養(yǎng)物質(zhì)（氨基酸），無殘留，不會(huì)和其它產(chǎn)生交叉抗性，不對腸道正常菌群產(chǎn)生影響，不產(chǎn)生抗藥性。澳大利亞、英、法等國家對乳酸鏈球菌素在食品中的添加不作任何限量要求，是食品防腐劑中的特例。我國于20世紀(jì)90年代批準(zhǔn)使用，目前廣泛應(yīng)用于乳制品、罐頭制品、魚類制品和酒精飲料等食品的防腐。</span> </p><h1> <span style="font-size:16px;">防腐劑對人體有害嗎？</span> </h1> <p> <span style="font-size:16px;">**：無論是防腐劑還是食品添加劑，都不能離開“量”來說事。在相同的食用量下，常用的防腐劑丙酸鈣毒性與食鹽相當(dāng)。而現(xiàn)在被使用的山梨酸鉀，毒性更是只有食鹽的1/2。</span> </p> <p> <span style="font-size:16px;">比如，允許在包裝醬菜中使用的山梨酸鉀，每千克包裝醬菜中的使用量為500毫克，按照一個(gè)成年人50千克的體重，每天允許攝入1250毫克山梨酸鉀來計(jì)算，即每天要吃2.5千克按照國家標(biāo)準(zhǔn)生產(chǎn)的包裝醬菜才能達(dá)到這個(gè)量。我們在日常生活中不可能每天吃那么多醬菜，所以不用擔(dān)心防腐劑攝入過量的問題。

style="font-size:16px;">人們越來越關(guān)注食品安全，我們都想吃到健康又放心的食品。于是，在某些媒體的催化下，食品防腐劑就成了眾矢之的。不少人就會(huì)覺得防腐劑就是“毒藥”，吃了添加防腐劑的食品就會(huì)損害健康。</span> </p> <p> <p> <span style="font-size:16px;">一說到防腐劑，人們往往認(rèn)為有害。其實(shí)，這是個(gè)很大的誤解。</span> </p> <p> <span style="font-size:16px;">我們首先得明確一點(diǎn)：廣義上來說，任何物質(zhì)都是有毒的，離開劑量談毒性是耍流氓。就連我們生命中不可或缺的水和氧氣，在劑量足夠的條件下也會(huì)引起水中毒和氧中毒呢！</span> </p> <p> <span style="font-size:16px;">防腐劑也不例外。我們國家針對食品防腐劑，制定了嚴(yán)格的使用標(biāo)準(zhǔn)，其中就包括使用范圍和安全劑量。一種防腐劑要在無數(shù)種有防腐效果的物質(zhì)中脫穎而出，成為被批準(zhǔn)使用的「法定防腐劑」，背后是有著無數(shù)有關(guān)毒理、代謝的研究支持其安全性的。</span> </p> <p> <span style="font-size:16px;">可以這么說，對于正常的成年人，在不超過安全劑量的情況下，這些防腐劑完全是安全的,并不會(huì)影響健康。</span> </p> <span style="font-size:16px;"></span> 食品防腐劑的使用方法，食品防腐劑現(xiàn)貨供應(yīng)湖北福潤德食品原料有限公司。湖北防腐劑廠家</p><p

style="font-size:16px;">目前使用的大多數(shù)防腐劑對人體都有一定的毒性，一旦過量會(huì)對健康產(chǎn)生危害。因此，各個(gè)國家對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)確檢測對食品衛(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)行色譜測定，得到各種組分的回歸方程及相關(guān)系數(shù)。</span> </p> <p> <span style="font-size:16px;">02紫外分光光度法原理：</span> </p> <p> <span style="font-size:16px;">利用苯甲酸鈉和山梨酸鉀的紫外吸收光譜差異, 采用多元線性回歸紫外吸光光度法同時(shí)測定飲料中苯甲酸鈉和山梨酸鉀。其中樣品無需預(yù)處理。</span> </p> <p> <br /> </p> <p> <br />
