[日清的性格]
  Since Nisin (also known as Streptococcus lactic peptide) is a polypeptide, it is rapidly inactivated in the intestine by digestive enzymes after consumption, Extensive micro-biological tests have not shown any cross resistant between Nisin and medical antibacterial drug.由于Nisin（也称为链球菌乳酸肽）是多肽，因此食用后其在肠中会被消化酶迅速失活，广泛的微生物学测试未显示Nisin与医用抗菌药物之间有任何交叉耐药性。 Nisin possesses anti-microbial activity against a wide range of Gram-positive bacteria and their spores which causes food spoilage, and especially inhibits the heat-resistant bacilli, such as B. Stearothermophilus, CI.乳链菌肽对多种革兰氏阳性细菌及其孢子具有抗微生物活性，这些细菌会引起食物变质，特别是抑制耐热杆菌，如B. Stearothermophilus，CI。 Butyricum and L. Monocytogenes.丁酸和单核细胞增生李斯特菌。 It is a natural food preservative which is highly efficient, safe and has no side-effects.它是一种天然食品防腐剂，高效，安全且无副作用。 In addition, it has excellent solubility and stability in food.另外，它在食品中具有极好的溶解性和稳定性。 It is not effective against Gram-negative bacteria, yeasts or mould.它对革兰氏阴性细菌，酵母菌或霉菌无效。
[应用]
Nisin can be used in a wide range of heat-processed foods.乳链菌肽可用于多种热加工食品。 These include: fresh milk, processed cheese and other dairy products, pasteurised liquid egg, processed meat, seafood, canned food, fruit drinks, plant protein drinks, baked products, instant food, beer, wine ect.其中包括：新鲜牛奶，加工奶酪和其他乳制品，巴氏杀菌液蛋，加工肉，海鲜，罐头食品，果汁饮料，植物蛋白饮料，烘焙产品，方便食品，啤酒，葡萄酒等。 It can also be used as a preservative in gelatin processing, cosmetics, drugs and health products.它也可以用作明胶加工，化妆品，药​​品和保健品中的防腐剂。
General dosage:0.03-0.2gram per kilogram food to be processed Nisin dissolve well in low pHcondition.一般用量：每公斤食品3-4克待处理乳链菌肽在低pH条件下溶解良好。 You may confect solution with PH5-0.02 and containing XNUMX%Nisin preparation by adding diluted acetic acid, diluted citric acid or XNUMXml/l HCL first, then put it into the food and mix fully.您可以先加入稀乙酸，稀柠檬酸或XNUMXml / l盐酸，然后用PHXNUMX-XNUMX配制含XNUMX％Nisin制剂的溶液，然后将其放入食品中并充分混合。 Or, dilutegradually and add.或者，稀释并添加。 Sometimes, Nisin can be dissolved directly in the original soup of the food.有时，乳链菌肽可以直接溶解在食物的原汤中。 Nisin can also be used together with other food preservatives.乳链菌肽也可以与其他食品防腐剂一起使用。
