International Milk Day milk quality problem still need to reflect on

People's Daily Jiangsu Windows Nanjing May 22 (Liu Jibing) May 22 is the "International Milk Day", has been in the forefront of the domestic dairy quality problems again aroused public concern.


 


reporter learned that Nanjing Wei Gang dairy group in order to prove to the public the safety of its dairy products, especially invited media representatives and 50 representatives of the public on "Milk Day" on the day to their Chunhua pasture in Jiangning District, visit and monitor the whole process of milk production. People who visit said that from milking to packaging "is indeed very sanitary and safe." ”


 


but at the same time, it needs to be noted that the awareness of dairy companies to improve their safety responsibility can not stay at the level of publicity activities, the occasional quality problems on the Internet require the government and dairy enterprises to reflect more comprehensively on the current quality issues involved.


 


reporter found that from the source analysis, milk quality problems need the following "three" thinking.


 


can produce "pure milk" without pasture?


 


in recent years, Wei gang milk has been "pasture can see, just dare to say fresh", "dairy safety No, milk source fresh seeing for the real" as their marketing slogan. Behind this comparative advantage, it is implied that some dairy companies in China do not have their own pasture but can also produce "fresh milk." This also confirms the internet on some dairy companies use milk powder to flush with pure milk speculation.


 


as a corroboration, there are people in the industry, and now many manufacturers of "pure milk", in fact, most of the milk powder to the reduction of milk.


 


data shows that 2006 Imports of total milk powder of 134,900 tons, despite the 2007 and 2008 by the impact of melamine, imports declined, only about 100,000 tons, but began to rebound in 2009, reached 247,800 tons, 2010 increased to 414,000 tons, 2011 years or even 657,200 tons. This growing demand for imports hints at the inadequacy of domestic dairy sources, and also sparked speculation about the use of powdered milk by experts in the industry.


 


Wei Rongro, executive vice president of the Western Dairy Industry Association, had made it clear in a media interview that "according to the national standard 1:8.5 calculation, the reduction of liquid milk should be 5.5862 million tons, almost accounted for more than half of the local milk source scale, the current market on the so-called pure milk, should be most for reducing milk. But many manufacturers have only stated that it is pure milk, but the nutritional difference between reduced milk and real fresh milk is great. ”


 


with milk powder to "pure milk", not only the source of quality problems, but also to blow the consumer's confidence in the quality of domestic milk.


 


Dairy new national standard backward 27


 


In addition to the source of milk sources, dairy products under the new GB milk quality problems are particularly concerned about.


 


March 2010, the Ministry of Health officially announced the new national standard of dairy products, the colony will be relaxed to 2 million, the protein reduced to 2.8 grams. This number is lower than the international standard of 3.0 grams, also lower than the 1986 old national standard 2.95 grams, and the total number of bacteria per ml of milk from the original 500,000 rose to 2 million, compared to the United States, the European Union 100,000 standards higher than 20 times times.


 


the setting of this new national standard is based on the 2008 "Melamine" Security incident reflection, the strange thing is that the standard is not 27 years ago security.


 


new national standard development expert drafting group team leader, national CDC nutrition and Food Safety deputy director Wang Zhutian, "This standard is suitable for our country now in this culture under a standard." ”


 


, the industry has explained that this standard is indeed to take into account the interests of the northern retail. These retail investors do not have standardized management, protein content is not high, the total number of colonies is difficult to control, if according to the 1986 standards, these farmers can only kill cattle. Once the cattle are killed, these areas will be cut off from the source of the economy, which will not only affect the supply of the milk source market, but also bring local instability.


 


for milk source adequacy and stability, the new national standard was "fit". In this respect, China's livestock products processing Research Council Honorary President of the Ministry of Agriculture (milk) consultant Sheng Xiang even blunt, so the Chinese dairy industry will have a crisis.


 


Indeed, from the national level of dairy quality standards have been reduced, the production of product quality will naturally be questioned. This is the current domestic dairy safety problems frequently, the quality of the lack of confidence in one of the reasons.


 


, a head of the dairy industry, although the national standards, but in the actual operation of many dairy companies or in accordance with the previous 500,000 of the Standard, "2 million bacteria per gram I dare not drink." ”


 


industry suggestions: Fresh milk should replace the normal temperature milk


 


quality problems because of the consequences of direct, it is easy to attract the attention of the audience, but the difference between the milk products are often overlooked.


 


, a dairy marketing department in Nanjing, the manager introduced the current production of pure milk has room temperature milk and fresh milk two kinds. Normal temperature milk is generally 130 ℃ above the high temperature comprehensive sterilization, but this kind of high temperature not only will all strains "sweep", but also to milk nutrients will cause a certain degree of loss. Fresh milk is pasteurized treatment, but the bacterial bud cell does not lose its activity, must be transported and preserved in 0-4 ℃.


 


because the room temperature milk storage time is longer, easy to drink, fit part of the public will milk as a gift mentality, coupled with pasteurization of pasteurized processing costs than normal temperature milk, so some of the milk enterprises and even the government is more highly recommended at room temperature milk production.


 


Foreign experimental data show: Compared with the raw milk before sterilization, with pasteurization sterilization of low-temperature fresh milk, vitamin B1, vitamin C and folic acid loss of about 10%, normal temperature milk loss of 20%-60%, low-temperature fresh milk protein denaturation rate of 0.43%, normal temperature milk for 94.8%. Protein denaturation will lose some or all of the nutritional effect.


 


Reporter learned that in Western countries at room temperature dairy cows are not popular with consumers, supermarkets sell more to low-temperature fresh milk mainly. According to the introduction, in the rising standard of living today, people add too much ingredients to the food more and more dislike, but the fresh, natural, non-polluting requirements are more and more prominent. Long shelf life and can be stored at room temperature of milk, in the process must be fully sterilized, may also need to add stabilizers, preservatives and so on. It is obviously unhelpful to add ingredients to the body's intake of too many stabilizers and preservatives.


 


more insiders believe that pasteurized sterilization of low-temperature fresh milk will be the mainstream of future milk consumption, fresh milk should replace the normal temperature milk. The understanding of this concept should be given the same attention as the quality problem.
