style="font-size:16px;">按照防腐劑抗微生物的主要作用性質(zhì)，可將其大致分為具有殺菌作用的殺菌劑和*具抑菌作用的抑菌劑。實(shí)際上，石家莊食品防腐劑價(jià)格，殺菌或抑菌并無界限，同一物質(zhì)，濃度高時(shí)可殺菌，而濃度低時(shí)只能抑菌，作用時(shí)間長可殺菌，作用時(shí)間短則只能抑菌。另外，由于各種微生物性質(zhì)的不同，同一物質(zhì)對一種微生物具有殺菌作用，而對另一種微生物可能*有抑菌作用。</span> </p> <p> <span style="font-size:16px;">按照防腐劑的應(yīng)用對象，可分為魚類、肉類防腐劑，面包、糕點(diǎn)防腐劑，飲料、醬料防腐劑，水果、蔬菜防腐劑，谷物、干果防腐劑等。</span> </p> <p> <span style="font-size:16px;">按照防腐劑的來源可分為化學(xué)合成防腐劑和天然防腐劑兩大類。</span> </p> <p> <span style="font-size:16px;">化學(xué)合成防腐劑包括酸型、酯型和無機(jī)鹽型。在食品工業(yè)中，酸型防腐劑常用的有苯甲酸及其鹽類、山梨酸及其鹽類以及丙酸等。酸性防腐劑具有應(yīng)用體系酸性越強(qiáng)、防腐效果越佳的特點(diǎn)，而在堿性條件下，酸性防腐劑幾乎沒有防腐效果。</span> </p> <p> <span style="font-size:16px;">在食品工業(yè)中，石家莊食品防腐劑價(jià)格，酯類防腐劑常用的有尼泊金酯類防腐劑及抗壞血酸棕櫚酸酯防腐劑，石家莊食品防腐劑價(jià)格。酯型防腐劑的特點(diǎn)是：低毒廣譜，對人體危害弱，且在很寬的 pH值范圍內(nèi)使用都有效。</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，的確會對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 /> 四川食品防腐劑廠家食品防腐劑廠商，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;">食品防腐劑在月餅中的應(yīng)用</span> </h1> <p> <span style="font-size:16px;"> 按照GB2760的定義，食品防腐劑是指能防止食品變質(zhì)、延長食品儲存期的一類食品添加劑，其對微生物的作用主要是通過影響細(xì)胞的亞結(jié)構(gòu)實(shí)現(xiàn)的。在食品體系中，食品防腐劑決不能用在已經(jīng)含有大量有害微生物的食品中去，只有在有害微生物比較少的時(shí)候使用才有效; 另外，食品防腐劑都有其抑菌譜，沒有一種食品防腐劑能夠可能出現(xiàn)的所有有害微生物，因此實(shí)際應(yīng)用時(shí)食品防腐劑通常情況下都是復(fù)配使用。</span> </p> <p> <span style="font-size:16px;"> 全世界使用的食品防腐劑約60 種，美國50種，日本43 種，我國允許使用的食品防腐劑有:</span> </p> <p> <span style="font-size:16px;">（1）苯甲酸及其鈉鹽、4 - 苯基苯酚、2 -苯基苯酚鈉鹽、丙酸及其鈉鹽、鈣鹽、單辛酸甘油酯、對羥基苯甲酸酯類及其鈉鹽( 尼泊金酯類) 、二甲基二碳酸鹽( 維果靈) 二氯苯氧乙酸、亞硫酸鹽類(二氧化硫、焦亞硫酸鉀、焦亞硫酸鈉、亞硫酸鈉、亞硫酸氫鈉、低亞硫酸鈉) 、二氧化碳、桂醛、聯(lián)苯醚、硫磺、納他霉素、乳酸鏈球菌素( Nisin)、山梨酸及其鉀鹽、雙乙酸鈉、脫氫乙酸及其鈉鹽、穩(wěn)定態(tài)二氧化氯、硝酸鹽、亞硝酸鹽、液體二氧化碳、乙二胺四乙酸二鈉、乙萘酚、乙酸鈉、乙氧基喹、仲丁胺、溶菌酶、ε -聚賴氨酸和ε - 聚賴氨酸鹽酸鹽共計(jì)30 種。</span> </p><h1> <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)酸型防腐劑對細(xì)胞膜的通透性有阻礙作用，會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;">過了保質(zhì)期的食物不能吃？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">過了保質(zhì)期的食品不能繼續(xù)銷售，但是并不意味著過了保質(zhì)期的食品就等于有害食品。有些食品發(fā)生的主要變化是感官上的變差，仍可以繼續(xù)食用，比如一些果汁、飲料以及脂肪含量不高的干糧谷物制品。有些食品的品質(zhì)影響不大，只是過了品質(zhì)期限。另外需要說明的是，食品保質(zhì)期是企業(yè)對于消費(fèi)者的質(zhì)量承諾，但包裝打開之后保質(zhì)期就作廢了。</span> </p> <p> <span style="font-size:16px;">不過，有些食品過了保質(zhì)期后可能會導(dǎo)致安全隱患，例如冷藏、罐裝、油炸的食品可能會出現(xiàn)微生物、過氧化值超標(biāo)等。因此，我們應(yīng)該養(yǎng)成購買食品看保質(zhì)期的習(xí)慣，同時(shí)按標(biāo)簽建議的貯存條件存放食物。</span> </p> <p> <span style="font-size:16px;"> </span> </p> <p> <span style="font-size:16px;">說到防腐劑，很多人就會想到電影里的木乃伊、泡尸體的福爾馬林等等，用處理尸體的防腐劑處理食物也太過聳人聽聞。其實(shí)食品防腐劑跟這些完全沒有關(guān)系。</span> </p> <p> <span style="font-size:16px;">絕大多數(shù)企業(yè)在食品添加劑的使用上都比較規(guī)范，只要按照國家標(biāo)準(zhǔn)規(guī)定的范圍和用量，防腐劑并不會對健康造成危害。而“不添加防腐劑”往往只是宣傳噱頭，這樣的產(chǎn)品一般本就無需添加防腐劑，例如已經(jīng)經(jīng)過巴氏熱加工熱處理的酸奶。</span> </p> <p> <br
