style="font-size:16px;">隨著人們的生活水平的提高，人們對健康生活的意識有所增強。當眾人談起各種食品防腐添加劑的時候，也會談之色變，說到防腐劑對人體有各種那樣的危害，含有防腐劑的食物吃多了會引起某種癥狀或疾病等等。各種詆毀防腐劑的言論真的是層出不窮啊，說起來防腐劑確實有點冤??！</span> </p> <p> <span style="font-size:16px;">防腐的目的，就是為了讓食物不容易發(fā)生變質。在空氣當中，時刻都存在各種微生物、細菌、。而暴露在空氣當中的食物，肯定就會受到微生物的侵染，進而發(fā)生腐爛發(fā)臭等。如果人類一旦不注意到這樣問題，那么很容易就會把有毒的有害的病菌細菌吃進了肚子，使得人們的健康受到威脅，食物中毒、生病甚至死亡。如果食物的安全質量都沒有保證，那又談何健康的生活。</span>

<br /> </p> <p> <span style="font-size:16px;">人工防腐劑能在更長的時間內保持新鮮感，但這些防腐劑中有些是對人體有害的，有些還有致作用。硝酸鈉是一種防腐劑，用于火腿、香腸和熏肉等，主要用來控制肉毒桿菌，但亞硝酸鈉可以與蛋白質發(fā)生反應，或者在高溫加熱的過程中，形成致的亞硝胺，而亞硝胺具有致作用。常用的苯甲酸鈉可以將瓶裝番茄醬的保質期延長至40周而沒有質量損失，然而，當與維生素C結合時，它就能形成致的苯。另外，對苯甲酸鈉的攝入也可能導致多動癥。</span> </p> <p> <span style="font-size:16px;">防腐劑用于延長食品的保質期，并延長食品的保質期。如果我們必須使用食品防腐劑,我們應該盡量食用那些對我們影響小，通常被認為是安全的防腐劑。對于那些通常不認為安全的防腐劑,不應該超過ADIs（可接受的每日攝入量）。為了盡量減少由于食品添加劑和防腐劑造成的健康問題的風險，應該盡量避免食用含有這些添加劑和防腐劑的食品，在購買食品前，應檢查其成分，或許不含人工添加劑和防腐劑的有機食品能為當代人提供一中備用選擇吧。</span>

style="font-size:16px;">主要包括苯甲酸、山梨酸、脫氫乙酸、亞硫酸鹽、亞硝酸鹽、對羥基苯甲酸的酯類等。天然防腐劑</span> </p> <p> <span style="font-size:16px;">是由生物體分泌或者體內存在的具有抑菌作用的物質，經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，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;">食品添加劑促進了現(xiàn)代食品工業(yè)的大力發(fā)展，并被譽為“現(xiàn)代食品工業(yè)的靈魂”，沒有食品添加劑就沒有現(xiàn)代工業(yè)。在過去30年里，食品添加劑的使用量可以說是逐年增加，現(xiàn)在每年的使用量已經超過20萬噸。其中，市場上用于抗氧化和抑菌的食品添加劑和防腐劑的數(shù)量已經超過3000種。我國我國規(guī)定使用的防腐劑有苯甲酸、苯甲酸鈉、山梨酸、山梨酸鉀、丙酸鈣等25種。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">食品防腐劑的主要作用是或預防引起食品或食品毒性的微生物的生長，從而增加食品的貨架期。一些常用的防腐劑，如硝酸鹽，已經在加工肉類和葡萄酒中使用了幾個世紀，這使它成為高酸食品、水果飲料、蘋果酒、碳酸飲料和泡菜中的有效物質。它還被用在了人造黃油、沙拉醬、醬油和果醬中。這些食品防腐劑的功能如下：</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;"> 1.改善或維持食物的營養(yǎng)價值；</span> </p> <p> <span style="font-size:16px;">2.提高質量，減少浪費；</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">3.提高消費者的可接受性和質量使食物更容易被接受；</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">4.食品中細菌、酵母和霉菌生長；</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">5.增加食品的安全和穩(wěn)定；</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">6.延長方便食品和加工食品的貨架期；</span> </p> <span style="font-size:16px;"></span> <p> <br />

style="font-size:16px;">1、液相色譜法</span> </p> <p> <span style="font-size:16px;">原理：配制苯甲酸鈉、山梨酸鉀和安賽蜜的標準溶液，以230nm為檢測波長，繪制標準曲線；樣品經超聲波脫氣、膜過濾后直接進樣，按上述條件進行色譜測定，得到各種組分的回歸方程及相關系數(shù)。</span> </p> <p> <span style="font-size:16px;">評價：液相色譜法具有分析速度快，分離效率高，測定結果準確等優(yōu)點，是檢測食品中苯甲酸鈉的常用的方法?，F(xiàn)在通用的較佳方法是將樣品用乙mi萃取, 再將萃取后的樣液在水浴烘干,然后用甲醇定容, 濾膜過濾后進行HPLC檢測。此試驗種用超聲萃取法，具有樣品預處理簡單，使操作簡單、快速、準確，值得推廣。但是此法于某種食品 ,應用于多種食品時 ,常常出現(xiàn)防礙峰干擾。</span> </p> <p> <span style="font-size:16px;">2、紫外分光光度法</span> </p> <p> <span style="font-size:16px;">原理：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測定飲料中苯甲酸鈉和山梨酸鉀。其中樣品無需預處理。</span> </p> <p> <span style="font-size:16px;">評價：樣品無須預處理，操作簡單，并且可同時測定多組分。加和性好, 準確度高。</span> </p> <p> <span style="font-size:16px;">3、氣相色譜法</span> </p> <p> <span style="font-size:16px;">原理：用分析天平準確稱取試樣并用鹽酸酸化，將山梨酸、苯甲酸和對羥基苯甲酸脂類用乙mi提取濃縮，用具有氫火焰離子化檢測器的氣相色譜儀分離測定，與標準比較定量。</span> </p> <p> <span style="font-size:16px;">評價：比較簡便和靈敏，但是設備投入成本高，存在違規(guī)操作，有易燃易爆的隱患。</span>
