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(zhǎng)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(lái)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。混合及灌裝過程中，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(wú)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;">人們?cè)絹?lái)越關(guān)注食品安全，我們都想吃到健康又放心的食品。于是，在某些媒體的催化下，食品防腐劑就成了眾矢之的。不少人就會(huì)覺得防腐劑就是“毒藥”，吃了添加防腐劑的食品就會(huì)損害健康。</span> </p> <p> <p> <span style="font-size:16px;">一說到防腐劑，人們往往認(rèn)為有害。其實(shí)，這是個(gè)很大的誤解。</span> </p> <p> <span style="font-size:16px;">我們首先得明確一點(diǎn)：廣義上來(lái)說，任何物質(zhì)都是有毒的，離開劑量談毒性是耍流氓。就連我們生命中不可或缺的水和氧氣，在劑量足夠的條件下也會(huì)引起水中毒和氧中毒呢！</span> </p> <p> <span style="font-size:16px;">防腐劑也不例外。我們國(guó)家針對(duì)食品防腐劑，制定了嚴(yán)格的使用標(biāo)準(zhǔn)，其中就包括使用范圍和安全劑量。一種防腐劑要在無(wú)數(shù)種有防腐效果的物質(zhì)中脫穎而出，成為被批準(zhǔn)使用的「法定防腐劑」，背后是有著無(wú)數(shù)有關(guān)毒理、代謝的研究支持其安全性的。</span> </p> <p> <span style="font-size:16px;">可以這么說，對(duì)于正常的成年人，在不超過安全劑量的情況下，這些防腐劑完全是安全的,并不會(huì)影響健康。</span> </p> <span style="font-size:16px;"></span>

對(duì)新鮮食品的需求不斷增長(zhǎng)，已導(dǎo)致食品制造商面臨食品安全和質(zhì)量方面的挑戰(zhàn)，食品添加劑“魚與熊掌”能兼得嗎？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">人工防腐劑能在更長(zhǎng)的時(shí)間內(nèi)保持新鮮感，但這些防腐劑中有些是對(duì)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(lái)控制肉毒桿菌，但亞硝酸鈉可以與蛋白質(zhì)發(fā)生反應(yīng)，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(zhì)期延長(zhǎng)至40周而沒有質(zhì)量損失，然而，當(dāng)與維生素C結(jié)合時(shí)，它就能形成致的苯。另外，對(duì)苯甲酸鈉的攝入也可能導(dǎo)致多動(dòng)癥。</span> </p> <p> <span style="font-size:16px;">防腐劑用于延長(zhǎng)食品的保質(zhì)期，并延長(zhǎng)食品的保質(zhì)期。如果我們必須使用食品防腐劑,我們應(yīng)該盡量食用那些對(duì)我們影響小，通常被認(rèn)為是安全的防腐劑。對(duì)于那些通常不認(rèn)為安全的防腐劑,不應(yīng)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(fēng)險(xiǎn)，應(yīng)該盡量避免食用含有這些添加劑和防腐劑的食品，在購(gòu)買食品前，應(yīng)檢查其成分，或許不含人工添加劑和防腐劑的有機(jī)食品能為當(dāng)代人提供一中備用選擇吧。</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(biāo)準(zhǔn)溶液，以230nm為檢測(cè)波長(zhǎng)，繪制標(biāo)準(zhǔn)曲線；樣品經(jīng)超聲波脫氣、膜過濾后直接進(jìn)樣，按上述條件進(jìn)行色譜測(cè)定，得到各種組分的回歸方程及相關(guān)系數(shù)。</span> </p> <p> <span style="font-size:16px;">評(píng)價(jià)：液相色譜法具有分析速度快，分離效率高，測(cè)定結(jié)果準(zhǔn)確等優(yōu)點(diǎn)，是檢測(cè)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(jìn)行HPLC檢測(cè)。此試驗(yàn)種用超聲萃取法，具有樣品預(yù)處理簡(jiǎn)單，使操作簡(jiǎn)單、快速、準(zhǔn)確，值得推廣。但是此法于某種食品 ,應(yīng)用于多種食品時(shí) ,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(shí)測(cè)定飲料中苯甲酸鈉和山梨酸鉀。其中樣品無(wú)需預(yù)處理。</span> </p> <p> <span style="font-size:16px;">評(píng)價(jià)：樣品無(wú)須預(yù)處理，操作簡(jiǎn)單，并且可同時(shí)測(cè)定多組分。加和性好, 準(zhǔn)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(zhǔn)確稱取試樣并用鹽酸酸化，將山梨酸、苯甲酸和對(duì)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(cè)器的氣相色譜儀分離測(cè)定，與標(biāo)準(zhǔn)比較定量。</span> </p> <p> <span style="font-size:16px;">評(píng)價(jià)：比較簡(jiǎn)便和靈敏，但是設(shè)備投入成本高，存在違規(guī)操作，有易燃易爆的隱患。</span> </p> <p> <br /> 山東食用防腐劑廠家</p></p><br /><p>文章來(lái)源地址:
