style="font-size:16px;">食品防腐自古以來就與人類的生活密切相關。人類很早以前就利用腌制、酒浸等方法對食品進行防腐處理。隨著社會經(jīng)濟的快速發(fā)展和食品需求的急劇增長，大量食物需要長途運輸和再加工，簡單的傳統(tǒng)防腐方法已經(jīng)不再滿足需要，食品防腐劑也就應運而生。用食品防腐劑對食物進行處理可以微生物的生長與繁殖,從而防止食品，湖北食用防腐劑生產(chǎn)廠家，達到延長食品保存時間的目的。</span> </p> <h2> <span style="font-size:16px;">食品防腐劑的作用機理</span> </h2> <p> <span style="font-size:16px;">一般認為,食品防腐劑的防腐功能是通過破壞微生物的細胞結構或干擾其生理功能來實現(xiàn)的，湖北食用防腐劑生產(chǎn)廠家。例如，細胞壁以及細胞質膜、代謝酶類，湖北食用防腐劑生產(chǎn)廠家、核酸和蛋白質體系等結構的完整和功能的正常運轉都是微生物生長繁殖所必需，缺一不可，故食品防腐劑只要干擾其中的任何一個環(huán)節(jié)就可以使微生物死亡或者停止生長。</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，酵母菌和好氧性細菌的活性，從而延長食品的保存時間，并保持原有食品的風味。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，在體內無殘留，是國際上公認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90％以上。此外常見的食品防腐劑還有丙酸鈣、脫氫乙酸、對羥基苯甲酸脂類等。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菌和微生物的滋長，如可產(chǎn)生劇毒物質肉的“肉毒菌”以及可產(chǎn)生強致物質黃曲霉的“黃曲霉”等。</span><span

<span style="font-size:16px;">過了保質期的食物不能吃？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">過了保質期的食品不能繼續(xù)銷售，但是并不意味著過了保質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。有些食品的品質影響不大，只是過了品質期限。另外需要說明的是，食品保質期是企業(yè)對于消費者的質量承諾，但包裝打開之后保質期就作廢了。</span> </p> <p> <span style="font-size:16px;">不過，有些食品過了保質期后可能會導致安全隱患，例如冷藏、罐裝、油炸的食品可能會出現(xiàn)微生物、過氧化值超標等。因此，我們應該養(yǎng)成購買食品看保質期的習慣，同時按標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，只要按照國家標準規(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 /> </p> <p> <br /> </p> <br /> <p> <br /> </p> <span style="font-size:16px;"></span> <p> <br /> </p><h1> <span style="font-size:16px;">很多食品需要用防腐劑保存</span> </h1> <p> <br /> </p> <p> <span style="font-size:16px;">“人們制作金華火腿、宣威火腿，必須使用亞硝酸鹽作為防腐劑。”日前，中國工程院院士、北京工商大學校長孫寶國在接受千龍網(wǎng)記者采訪時解釋說，對于很多食品而言，不進行“防腐”就很難長時間保存。例如，如果不使用亞硝酸鹽作為防腐劑，火腿上會生成肉毒桿菌等多種細菌，輕則會引起人食物中毒，重則危及人的生命。</span> </p> <p> <span style="font-size:16px;">孫寶國院士表示，目前亞硝酸鹽作為一種食品防腐劑，是國際上公認的、安全的防腐劑。防腐劑是指一類加入食品中能防止或延緩食品的食品添加劑，其本質是具有微生物增殖或殺死微生物的一類化合物，又稱為保藏劑。使用過程中或分解后無毒，一般都不會損害人體健康。</span> </p> <p> <span style="font-size:16px;">防腐劑的來源主要有天然和合成兩類，以合成的商業(yè)化應用多。我國的GB2760—2011列出防腐劑共有27種，化學防腐劑包括有機的和無機的，有機的防腐劑主要是苯甲酸及其鹽類、山梨酸及其鹽類、對羥基苯甲酸及其酸類、乳酸等。</span> </p> <p> <span style="font-size:16px;">“人們常見的可樂中的二氧化碳也是一種防腐劑。</span> </p> <p> <br /> 食品級防腐劑生產(chǎn)廠家，食品防腐劑現(xiàn)貨供應湖北福潤德食品原料有限公司。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

<span style="font-size:16px;">食品防腐劑是用于防止食品因微生物引起的變質，提高食品保存性能，延長食品保質期而使用的食品添加劑。飲品中常用的防腐劑有山梨酸鉀，檸檬酸，乳酸，笨鉀酸鈉等。</span> </p> <p> <span style="font-size:16px;">那么，飲品中為什么要添加防腐劑，什么情況下飲品不需要添加防腐劑呢？我們就來聊一聊關于飲品防腐的那些影響因素。</span> </p> <p> <span style="font-size:16px;">由于飲品流動性及傳熱性較好，采用管式或者板式密閉殺菌機UHT殺菌（超高溫瞬時滅菌工藝），均能殺滅產(chǎn)品中的常規(guī)微生物。中性飲品（pH>4.6）通常采用135-140℃×4-10秒滅菌，酸性飲品（pH<4.6）通常采用105-121℃×5-15秒滅菌。但因為殺菌后的包裝材料和生產(chǎn)工藝不同，有的飲品必須使用防腐劑，有的完全不需要防腐劑。</span> </p> <p> <span style="font-size:16px;"> 碳酸飲料糖漿殺菌后，方能混入二氧化碳?；旌霞肮嘌b過程中，均存在微生物污染風險，所以幾乎所有的碳酸飲料均含防腐劑。其他非碳酸飲料，有的廠商為降低包材和設備成本，在非無菌灌裝環(huán)境灌裝，采用非耐熱包裝，如不耐熱塑料瓶（輕質量）、非蒸煮型塑料袋，因此必須添加防腐劑。</span> </p> <p> <br />

style="font-size:16px;">防腐劑的作用機理和安全性</span><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理是利用對細胞膜的干擾功能，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菌引起的食品變質有作用。</span> </p> <p> <span style="font-size:16px;">安全性：乳酸鏈球菌素是世界公認安全的天然食品防腐劑，在人體內終被降解為可被消化吸收的營養(yǎng)物質（氨基酸），無殘留，不會和其它產(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90年代批準使用，目前廣泛應用于乳制品、罐頭制品、魚類制品和酒精飲料等食品的防腐。</span>
