Methods The process, determination of production technology, test of samples and statistical analysis of test results in pduction of acidophilus milk were anlayzed based on the HACCP principle.

应用HACCP的原理和方法，对酸牛乳的生产过程进行危害分析。对各工序进行现场观察、工艺条件测量、采样检验以及对检验结果进行统计分析。

Results The examination of raw materials, sterilization, fermentation, cryopreservation, processing device, containers, packing materials and asceptic manipulation were the main factors influencing the hygienic quality of acidophilus milk.

结果 确定原料验收、杀菌、发酵、冷藏、加工设备、容器及包装材料的消毒、灌装环境和无菌操作是影响酸牛乳卫生质量的主要原因，为关键控制环节。

The stability of acidified fruit milk affected by the factors such as material quality, the milk content, the system acidity, additive categories, the process and parameters of machining and so on, it is a difficulty problem in new dairy products development.

酸性果乳的稳定性受到原料质量、牛乳含量、体系酸度、添加剂种类和用量以及加工工序和参数等诸多因素的影响，一直是新型乳制品开发中的难题，而要提高产品的稳定性，关键问题还需解决牛乳酪蛋白在酸性条件下的稳定性。

Infant formula milk powders is the main infant food of simulation human milk ,but it could affect digesting hardly and hypersusceptibility on some infants, which is related to the difference of protein component of bovine milk and human milk.

以牛乳为主要基料的婴幼儿配方奶粉会使婴幼儿食用后出现消化不良和过敏反应，主要是母乳与牛乳蛋白质组成不同而引起的。

After many years of effort, the technique of raising dairy cows was promoted. The production increased to 6,067 kg per head of multiparous cows in 2007. Due to the price of feed rising dramatically and the purchased price of raw milk not increasing, the number of dairy farms was decreased to 619. The production cost of the raw milk increased from NT$21.85 to NT$24.97 in the past five years and the quality of raw milk improved significantly.

经过多年努力，酪农生产技术提升，平均每头经产牛年产乳量，到2007年已高达6，067公斤，但因饲料价格高涨，乳价收购价格没有相对提高，所以酪农户数降到619户；近五年牛乳每公斤生产成本，由21.85元增至24.97元，牛乳品质进步很多，每c.c。

But after ultra-high pressure treatment, the all free amino acid can be measured except alanine and cystine and the content of asparagines is lower. The content of free amino acid is the highest in ultra-high pressure sterilize milk, the pasteurism milk is second, the ultra high temperature sterilized milk is lowest.

但是牛乳经过超高压杀菌处理以后，除丙氨酸和胱氨酸未检出，且超高压杀菌处理以后的天门冬氨酸的含量略低以外，其余游离氨基酸均可检出，而超高压杀菌牛乳中游离氨基酸的含量最高，巴氏杀菌乳中的含量次之，超高温瞬时杀菌乳中的含量最低。

Hippuric acid can be well separated by RP-HPIC on ODS column and with methanol-water- acetic as mobile phase and UV detector at 254nm.

在生产酸牛乳时，原料乳中马尿酸脱甘氨酸生成苯甲酸，从而使酸牛乳中天然苯甲酸含量增加[2]。

Shandong sinder technology limited company,qingdao 266061,shandong,chinaabstract:to provide the eukaryotic expression vector carrying 6x histidine-tag and human growth hormone in expremental animal and cell culture,according to the published nucleotide sequence of the lactofericin b and human growth hormone,synthesis sequence was ligated with pmt-18 vector.

以牛乳素为目的基因，构建含有组氨酸标签、人生长激素信号肽的真核表达载体，为利用牛乳素在活体动物及培养细胞中的表达提供基因材料。

This study was undertaken to determine the optimum parameters for hydrolyzing casein in milk .

以胰蛋白酶直接对牛乳中酪蛋白进行水解，以水解后的口感和组织状态为测定指标，利用单因素试验确定出牛乳较理想的水解参数范围值：时间20～40 min，水解温度40～60℃和酶质量分数0.08%～0.30%。

Somatic Cell Counting is an important index of milk quality measurement and bovine mastitis diagnosis.

牛乳体细胞数量是牛乳质量检测及奶牛乳腺炎诊断的一项重要指标。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
