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(zhì)，提高食品保存性能，延長食品保質(zhì)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(guān)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(dòng)性及傳熱性較好，采用管式或者板式密閉殺菌機(jī)UHT殺菌（超高溫瞬時(shí)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?yàn)闅⒕蟮陌b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(fēng)險(xiǎn)，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(shè)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(zhì)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;">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，已被所有國家和地區(qū)允許使用。</span> </p><h1> <span

style="font-size:16px;">對(duì)羥基苯甲酸酯類的防腐機(jī)理是對(duì)微生物的細(xì)胞膜有破壞作用，導(dǎo)致細(xì)胞內(nèi)的蛋白質(zhì)變性，使微生物細(xì)胞的呼吸酶系統(tǒng)失去活性。對(duì)羥基苯甲酸酯類防腐劑的活性成分主要是分子態(tài)發(fā)揮作用</span> </p> <p> <span style="font-size:16px;">安全性：相對(duì)于苯甲酸，其毒性低、性能穩(wěn)定，是一種廣譜型防腐保鮮劑。對(duì)羥基苯甲酸酯類防腐劑的安全性很高，日本使用多的是丁酯。我國主要使用乙酯和丙酯，允許用于果醬、醋、醬油、飲料等食品的防腐。</span> 食品級(jí)防腐劑有哪些，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="font-size:16px;">食品防腐自古以來就與人類的生活密切相關(guān)。人類很早以前就利用腌制、酒浸等方法對(duì)食品進(jìn)行防腐處理。隨著社會(huì)經(jīng)濟(jì)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(yùn)輸和再加工，簡(jiǎn)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(yīng)運(yùn)而生。用食品防腐劑對(duì)食物進(jìn)行處理可以微生物的生長與繁殖,從而防止食品，達(dá)到延長食品保存時(shí)間的目的。</span> </p> <h2> <span style="font-size:16px;">食品防腐劑的作用機(jī)理</span> </h2> <p> <span style="font-size:16px;">一般認(rèn)為,食品防腐劑的防腐功能是通過破壞微生物的細(xì)胞結(jié)構(gòu)或干擾其生理功能來實(shí)現(xiàn)的。例如，細(xì)胞壁以及細(xì)胞質(zhì)膜、代謝酶類、核酸和蛋白質(zhì)體系等結(jié)構(gòu)的完整和功能的正常運(yùn)轉(zhuǎn)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(gè)環(huán)節(jié)就可以使微生物死亡或者停止生長。</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(duì)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(huì)導(dǎo)致安全隱患，例如冷藏、罐裝、油炸的食品可能會(huì)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(huì)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(huì)對(duì)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>
