style="font-size:16px;">一、食品的變質(zhì)</span> </p> <p> <span style="font-size:16px;">食品在化學(xué)或物理性質(zhì)上發(fā)生的不利改變都稱為食品變質(zhì)。造成食品變質(zhì)的原因包括物理、化學(xué)和生物三個(gè)方面。由于微生物的作用使食品發(fā)生了有害變化，降低或失去了原有的或應(yīng)有的營養(yǎng)價(jià)值和商品價(jià)值的過程被稱為食品的變質(zhì)。食品變質(zhì)是微生物的污染、食品的性質(zhì)和環(huán)境條件綜合作用的結(jié)果。</span> </p> <p> <span style="font-size:16px;">1、微生物的污染</span> </p> <p> <span style="font-size:16px;">引起食品變質(zhì)的微生物種類很多，有各種細(xì)菌、霉菌和酵母菌。例如嗜熱脂肪芽孢桿菌就是常見的導(dǎo)致食品的微生物之一，可導(dǎo)致罐藏食品平酸。微生物引起食品變質(zhì)的類型包括：細(xì)菌引起的變質(zhì)、霉菌引起的變質(zhì)以及食品發(fā)酵。</span> </p> <p> <span style="font-size:16px;">2、食品的性質(zhì)</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">食品變質(zhì)的程度和快慢也與食品本身的營養(yǎng)成分、水分、 pH值、酶和滲透樂等因素有關(guān)。例如，食品的 pH值為6時(shí)適合微生物增殖，pH＜4.5時(shí)可多種細(xì)菌的生長；含水量高的食品比含水量低的食品容易，當(dāng)水分活度＜0.7時(shí)，一般微生物不能繁殖；高滲透可以微生物的生命活動(dòng)，10％鹽漬或60％糖漬的食品可耐保藏。</span> </p> <p> <br /> </p> <span style="font-size:16px;"></span>

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(huì)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(gè)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(shí)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(duì)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>
