Dispute that the new national standard of dairy products recurs
"Protein content of milk is low, take in influence to consumer's nutrition? The colony is tall in total number, will bring and drink the safe problem? " Recently, intensify with the safe new national standard dispute of dairy products once again, many people send out similar doubt.
"Protein standard reduces in the national standard, drinking and nutrition that will not be given to consumers takes in and brings obvious influence. " Yesterday, food science of China Agricultural University and project institute's associate professor Li XingMin of the nutrition said when being interviewed by reporter, look in term of leading the trade to develop and encourage milk quality to promote only, the national standard should be made a little higher. In addition, the national standard is only the basic entry standard, enterprises can consult it and set up more high-standardly, implement the high quality and favourable price and harvest the milk.
It has not been obviously influenced that protein standard takes in nutrition
The safe new national standard of dairy products was announced at last the end of March, and implemented in the same year formally from June 1. During this time, have initiated countless disputes. The ones that caused the dispute to intensify once again this time are still two focuses disputed originally: First protein content. In the new national standard, every 100 grams of albumen content include 2.8 grams, this figure is lower than 3.0 grams of the international standard, also less than 1986 2.95 grams of the old national standard; Second the total number of the colony in per ml of milk. The new standard stipulates for 2 million, 20 times higher than the standard of U.S.A., European Union 100,000.
Li XingMin says, raw milk protein standard reduces, will not take in and bring too great influence to public nutrition in the new national standard. Because compared with original standard, protein content has been only reduced by 0.15 grams in every 100 grams milk. "Do a piece of simple calculating. Learning the standard according to China nutrition, the adult should take in between 60 grams and 70 grams of animal's albumens in one day. The new national standard requires, include 2.8 grams of proteins in every 100 grams milk, drink 500 grams of milk and take in 14 grams of proteins every day, reduced protein intaking amount is less than 1 gram, takes in influence not big on whole nutrition compared with in fact standard. Add the absorption of albumens such as the meat,etc. at ordinary times, it is enough. "
"Compared with protein content, the standard of total number of the colony needs paying close attention to even more. " Li XingMin says, there are greater relations in total number of the colony and people's health in the original milk. Bacterium's content is high, need more harsh condition and kill more bacteria at first, for example improve the sterilization temperature and lengthen the time of sterilization, but this will destroy the nutrition in the milk. Secondly, may produce the toxin in storage, transportation, this kind of toxin is more heat-resisting than the bacterium, in the milk is processed, can't totally kill it even if the high temperature sterilizes. Third, there is much colony will produce enzyme, and decompose the material in the milk and cause the mouthfeel of the milk to drop, and destroy the nutritive value. For example, acerbity appears, precipitate the irregularity etc.. Finally, the milk sterilizes the one with certain efficiency, if there is much colony in the original milk, residual fungus in the finished milk too can become more.
"Cast aside these factors and does not discuss, the total number of the colony proves at least it is bad that the cow cultivates the sanitary condition high, the original milk is gathered, stored, transported unstandardly, there is pollution, all these are apt to bring the potential safety hazard. " Li XingMin thinks, the government should issue the policy and encourage enterprises to set up the total number of the colony to purchase the standard while purchasing in the raw milk in grades, lead the agricultural standardized scale of milk to be cultivated, improve and cultivate competence constantly.
Each side of index function of body cell has different versions
Reporter notice until the intersection of dairy products and new national standard the intersection of dispute and sound recur, body the intersection of cell and these professional term come into people's visual field again.
Materials reveal body cell mean lymphocyte, loss upper leather cell, neutral leucocyte one general name of cell. The cell quantity of body weighs one of the fresh milk quality and important index of the security. It is reported, discuss, in the draft, stipulate the intersection of body and standard that cell counted in the raw milk in order to be been less than or equal to 1 million ml in the intersection of dairy products and new national standard, but in the document later on, this regulation is deleted. According to the explanation of the expert of the Ministry of Agriculture, the reason is that " the body cell index is cow's health index, it is not a quality safety index of raw milk. "
Last year after the new national standard of dairy products was announced, the related departments had organized the expert to hold the seminar. The expert from association of Shanghai milk points out, " the body cell index is cow's health index, it is not a quality safety index of raw milk " Belong to the professionals of misleading consumers and the milk industry. The raw milk is defined very clearly speaks: From accord with national about requirement healthy the intersection of milk and whom domestic animal push out of in the breast have whom any composition change the milk is the qualified raw milk often. Domestic animal's breast of healthy milk is a prerequisite. "As the cow has suffered from inflammation of breast, can the raw milk quality secreted be safe? "
According to the introduction of this expert, it is a normal physiological phenomenon that the healthy cow's mammary gland secretes body cells, body cells are counted and less than or equal to 200,000 ml, will not cause the harmful effects to mammary gland health and milk quality; Body cells are counted like between 500,000 ml in 200,000 ml, prove the specific cow suffers from the inferior clinical type inflammation of breast, the milk output drops by 6%; Body cells are counted and up to 500,000 ml 1 million ml, prove that there is inferior clinical type inflammation of breast that exists in the herds of cattle, the milk output drops by 18%; Such as body cell number gts; 1 million ml, prove the clinical type inflammation of breast in Central Asia of herds of cattle prevails seriously; Act as body cell number gts; 1,500,000 ml, prove at least more than 50% of the milk districts are infected in the herds of cattle, the milk output will drop by 30%. As body cells are counted raises, the composition in the milk changes, casein is reduced, milk calcium is reduced, the supersession product increases. So, it is often an important sign of weighing inflammation of cow's breast that body cells are counted high, to break out, too can make cow the intersection of body and cell count, rise to 1 million mls of more than in the milk some infectious disease. So, body cells will threaten the security of dairy products to count the high raw milk.
According to the introduction of Li XingMin, according to the international practice, body cells are counted and has already been regarded as and already weigh cow's healthy index, also regarded as the safe quality index of raw milk. At present, our country cultivates a standard to the cow, are released by the Ministry of Agriculture, stipulate the body cell number of the milk among them, but this standard is a proposed standard, do not force the standard. "Speak in term of being ensure the milk quality and security, body cells should include to count in the relevant national standard, implement by force. "
Drink the good milk, must raise the good cow
"Dairy products safe national standard it makes revision to be open, not dynamic. " Yesterday, synthesized and coordinated the officers related to sanitary control office to tell reporters in food security of Ministry of Public Health, "launch following of standard assess, consult international standard, listen to the intersection of food and operator and the intersection of consumer and opinion extensively, revising and improving the standard constantly, it is a meaning in the question of safety standard management of food of our country. "
It is introduced as to in the industry " the new national standard of dairy products is stapled too low " Doubt,it is last for July, it if you can't issue specially by question and answer, respond for to last expert Ministry of Public Health: The index of total number of proteins and colony of the raw milk standard is that the science is rational, accord with our country and develop reality, can protect the agricultural interests of small-scale milk in a large amount of, safeguard the milk industry of our country to develop steadily. The background of this kind of explanation is, " at present, the cow of our country raises the proportion scattered higher on a small scale, 100 above scale it cultivates proportions to be 23.1% only, proportion 32.4% under the 5, the current situation that cultivate on a small scale in short term difficult to change. "
More than one year passed by, ordered and ordered the low dispute on the new national standard of dairy products high on earth, still it is difficult to have unified opinions. This dispute that seems to come to nothing, a exposed one is the awkward situation of the dairy products trade of our country: Some structural defect fast-developing surface prosperous to conceal milk industry. Drink the good milk, must raise the good cow. However, in the past during the last ten years, people's attention including investment concentrated on more dairy products and produced and sold links, have not paid the due attention in cultivating links, lead to the fact that it is unstable to disconnect, cultivate competence lagging behind, original milk quality in front and at the back of the industry chain, even give and drink and bring the potential safety hazard.
China food science and technology learns relevant experts how to think, have considered the national conditions of our country in some indexes of the new dairy products national standard, guarantee standard practicability, but develop for high quality of the trade, high efficiency, propose issuing as soon as possible and new standard some related sector standards, enterprise's standards and relevant policies and measures, encourage enterprises and the place to make stricter enterprise and local standard. For example grow the lactic high quality and favourable price and purchase the policy, set up the forming mechanisms of enterprises and the agricultural raw milk purchasing price participated in of milk,etc..
