中国人广为食用干酪为期不远 总被引:1,自引:0,他引:1
人们利用黄牛、牦牛挤奶食用已有5000多年的历史,早在1300年前,我们的祖先就已熟知牛奶具有较高的营养价值。由于种种原因,我国奶业在改革开放前发展缓慢,到1978年我国奶牛只有47.5万头,年产奶97万t,人均只有1kg。改革开放后,奶业迅猛发展,2001年奶牛存栏566万头,产奶1025万t。而西方国家奶业发达,消费水平高,人均年消费在几十kg到几百kg。一、世界乳制品消费走过了三个阶段在牛奶消费过程中,各国一般都经过三个阶段。第一阶段,奶粉阶段。奶牛饲养在山区、牧区,距离城市较远,人们就把牛奶制作成奶粉或炼乳,运到城市供人们消费。第二阶段,液… 相似文献

A range of three commercial starch ingredients (differing in amylose/ amylopectin ratios) were incorporated into a processed cheese formulation. The use of starch in the cheese system significantly increased the cook (final) viscosity of the cheese mixture compared to the control formulation. Starch containing high amounts of amylose produced hot cheese pastes with the highest final viscosity values. Processed cheese firmness was significantly increased with starch addition. Cheese products with high‐amylose starch recorded a five‐fold increase in firmness, whereas high amylopectin‐based starches yielded a two‐fold increase in firmness. No significant differences were observed in the adhesive and cohesive properties of the processed cheeses when starch was added to the formulation. The addition of starch to the cheese samples significantly reduced the degree of melt of the processed cheese samples compared to the control. The high‐amylose starch exhibited a minimum of a 26% reduction in the degree of melt compared to the control sample. The amount of cheese melt decreased with increased starch content. 相似文献

如何开发中国奶酪市场 总被引:1,自引:0,他引:1
<正> 奶酪可能是世界上品种最繁多的营养食品之一。众所周知,奶酪中包含了乳中的几乎全部营养物质,其中脂肪和蛋白含量和浓度是普通的液体奶和酸奶的数倍以上,是优质的乳制品。由于种类繁多,奶酪的分类也有多种方法。可以是按产品的组织状态,分为软质、半软质、半硬质和硬质奶酪等。按照加工方式,分为原制和再制两大类,前者经过乳的发酵和凝乳的成熟,而后者加工过程 相似文献

Detection of Virulence Genes and Growth Potential in Listeria monocytogenes Strains Isolated from Ricotta Salata Cheese 下载免费PDF全文

Ricotta Salata is a traditional ripened and salted whey cheese made in Sardinia (Italy) from sheep's milk. This product is catalogued as ready‐to‐eat food (RTE) since it is not submitted to any further treatment before consumption. Thus, foodborne pathogens, such as Listeria monocytogenes, can represent a health risk for consumers. In September 2012, the FDA ordered the recall of several batches of Ricotta Salata imported from Italy linked to 22 cases of Listeriosis in the United States. This study was aimed at evaluating the presence and virulence properties of L. monocytogenes in 87 samples of Ricotta Salata produced in Sardinia. The ability of this product to support its growth under foreseen packing and storing conditions was also evaluated in 252 samples. Of the 87 samples 17.2% were positive for the presence of L. monocytogenes with an average concentration of 2.2 log10 cfu/g. All virulence‐associated genes (prfA, rrn, hlyA, actA, inlA, inlB, iap, plcA, and plcB) were detected in only one isolated strain. The Ricotta Salata samples were artificially inoculated and growth potential (δ) was assessed over a period of 3 mo. The value of the growth potential was always >0.5 log10 cfu/g under foreseen packing and storing conditions. This study indicates that Ricotta Salata supports the L. monocytogenes growth to levels that may present a serious risk to public health, even while stored at refrigeration temperatures. 相似文献
