style="font-size:16px;">食品含有豐富的營養(yǎng)物質(zhì)，這些物質(zhì)可以給人體提供能量和豐富的營養(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，在短時間內(nèi)就可能在食品中迅速生長繁殖，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和繁殖，延長食品的保存時間。”北京工商大學(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”和“無機”來具體劃分。苯甲酸及其鹽類、山梨酸及其鹽類、對羥基苯甲酸及其酯類等屬于“有機”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”類別。而天然防腐劑通常是從動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，我國食品安全國家標(biāo)準(zhǔn)對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)實驗，證實允許使用的食品防腐劑對人體不會產(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對消費者的身體健康造成一定損害。</span> </p> <span

style="font-size:16px;">防腐劑的作用機理和安全性</span><span style="font-size:16px;"></span> </h1> <p> <span style="font-size:16px;">苯甲酸及其鹽類防腐劑為結(jié)晶狀粉末或白色顆粒，無臭，微帶安息香氣味。苯甲酸及其鹽是食品工業(yè)中常見的一種防腐保鮮劑。其防腐機理是苯甲酸類防腐劑具有脂溶性強的特點，容易通過細(xì)胞膜進入細(xì)胞體內(nèi)，導(dǎo)致微生物細(xì)胞膜的通透性**擾，細(xì)胞膜對相關(guān)氨基酸的吸收被有效，苯甲酸分子是以酸化細(xì)胞體內(nèi)儲堿的方式使細(xì)胞的呼吸酶系失去活性，從而對食品起到防腐保鮮的作用。</span> </p> <p> <span style="font-size:16px;">安全性：一般情況下，苯甲酸被認(rèn)為是安全的，在食品中添加少量苯甲酸時，對人體并無。人體攝入少量的苯甲酸后，苯甲酸與體內(nèi)的一種氨基酸生成一種無害的新物質(zhì)，隨尿液排出。</span> </p><h1> <span style="font-size:16px;">食品防腐劑有毒？方便面32小時不消化？別再被騙了！</span> </h1> <p> <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

style="font-size:16px;">防腐劑作用的機理</span> </h1> <p> <span style="font-size:16px;">防腐劑的防腐作用主要是通過延緩或微生物增殖作用來實現(xiàn)的。一般認(rèn)為，主要是其能夠影響細(xì)胞的亞結(jié)構(gòu)，這些亞結(jié)構(gòu)包括細(xì)胞壁、細(xì)胞膜、與代謝有關(guān)的酶、蛋白質(zhì)合成系統(tǒng)及遺傳物質(zhì)。由于每個亞結(jié)構(gòu)對菌體而言都是必需的，因此食品防腐劑只要作用于其中的一個亞結(jié)構(gòu)便能達(dá)到殺菌或抑菌的目的。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">防腐劑與殺死微生物的機理十分復(fù)雜，目前使用的防腐劑的作用機制一般認(rèn)為對微生物有以下幾方面的作用。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">(1)作用于微生物的細(xì)胞壁和細(xì)胞膜系統(tǒng)</span> </p> <p> <span style="font-size:16px;">通過對微生物細(xì)胞壁或細(xì)胞膜的作用，影響其細(xì)胞壁質(zhì)的合成或細(xì)胞質(zhì)膜中巰基的失活，可使三磷酸腺苷等細(xì)胞物質(zhì)滲出，甚至導(dǎo)致細(xì)溶解。</span> </p> <p> <span style="font-size:16px;">(2)作用于微生物的細(xì)胞原生質(zhì)</span> </p> <p> <span style="font-size:16px;">通過對部分遺傳機制的作用，或干擾細(xì)菌等微生物的正常生長，甚至令其失活，從而使細(xì)胞凋亡。</span> </p> <p> <span style="font-size:16px;">(3)作用于微生物的酶或功能蛋白</span> </p> <p> <span style="font-size:16px;">通過與酶的巰基作用，破壞多種含硫蛋白酶的活性，干擾微生物體的正常代謝，從而影響其生長和繁殖。通常防腐劑用于微生物的呼吸酶系，如乙酰輔酶 A縮合酶、脫氫酶、電了轉(zhuǎn)遞酶系等。通過竹用于蛋白質(zhì)，導(dǎo)致蛋白質(zhì)部分變性、蛋白質(zhì)交聯(lián)而使其他的生理作用不能進行。</span> </p> <p> <br /> 防腐劑報價，食品防腐劑現(xiàn)貨供應(yīng)湖北福潤德食品原料有限公司。東莞食用防腐劑廠商</p><p

style="font-size:16px;">I類防腐劑是常見的鹽、糖、葡萄糖、葡萄糖、香料醋或醋酸、蜂蜜、可食用植物油；</span> </p> <p> <span style="font-size:16px;">II類防腐劑是苯甲酸，硝酸鹽或亞硝酸鈉或鉀鹽等，其在火腿中為常見。苯甲酸鈉主要用于果汁、腌菜和軟飲料，以防止酸性食物中的微生物生長；苯甲酸主要用于果汁、碳酸飲料和泡菜；二氧化硫和亞硫酸鹽可以霉菌和細(xì)菌，也可以細(xì)菌的產(chǎn)生，可以用來控制不受歡迎的細(xì)菌和野生酵母，而不會影響到二氧化硫耐受培養(yǎng)的酵母；氯化鈉作為防腐劑，已經(jīng)被使用了幾個世紀(jì)，以防止食物的變質(zhì)，鹽的活性與它降低水活性的能力有關(guān)，從而影響微生物的生長；乳酸鏈球菌素主要用于革蘭氏陽性菌的生長；食物酸可以使味道更“鋒利”，同時也起到防腐劑和抗氧化劑的作用。常見的食物酸包括醋、檸檬酸、酒石酸、蘋果酸、富馬酸和乳酸。山梨酸和山梨酸鹽對酵母和霉菌有效，山梨酸鹽可以在葡萄酒、果汁、干果、白干酪、肉類和魚類產(chǎn)品中酵母菌的生長；在可樂軟飲料中使用磷酸來降低pH值。醋酸用于蛋黃醬和沙拉醬中，類似的功能還有檸檬酸、酒石酸、蘋果酸和乳酸；直鏈羧酸、丙酸和酸二酸，主要利用它們的性能；丙酸主要利用抗的特性。</span>
