The turmoil in the dairy industry can always stir the public's sensitive nerves.

A few days ago, the comparison between the nutritional components of buffalo milk and Holstein milk (black-and-white milk) has become a hot topic in the dairy industry. The incident was caused by a set of data listed by Guangxi Huangshi Dairy in its advertising campaign. This set of data shows that some nutrients contained in buffalo milk are higher than the content in ordinary black-and-white milk, but the data is consistent with The similar number in the Wangshi Dairy's 2009 prospectus is quite different, and some media have questioned this.

What is the difference between water and milk? Is it as true as Wong's milk industry claimed that it is higher than the black and white water milk? How much is higher in the end? These problems became a cloud of doubt and shrouded the hearts of the public. To understand the true answer, the reporter specially visited Professor Li Shengli, an authoritative expert in China's dairy industry, China Agricultural University.

Regarding the incidents reported by the media in the past, Prof. Li said that he has also been paying close attention and has in-depth knowledge of the relevant circumstances. He believes that as a basic food for national nutrition, dairy products have always existed in the industry structure of Beizhongnanguang and Beidai South, and the development of the water-milk industry is crucial to solve the problem of milk shortage in the south. As a whole, let the public think about water. Milk has a clear and comprehensive understanding that helps to optimize the soft environment for the development of batter milk. Therefore, it is necessary to take a close look at the facts of the viewing and viewing the differences in the variety and milk production of buffalo milk and Holstein milk in a scientific and fair manner. At the same time, it is necessary to let the public understand some basic conditions for milk milk ingredient research.

Professor Li introduced that although there are species that produce milk, in terms of taxonomy, buffalo is not the same genus as common Holstein dairy cows. The annual production of Holstein cows is very high, with an average of over 7 tons, and even a high of 11 tons, while the annual output of milk buffalo is only about 2 tons, a big difference. Genetically, there is a negative correlation between milk production and milk composition. The higher the milk yield, the lower the nutrient dry matter content, especially the milk fat, milk protein and other nutrients. On the one hand, it is the variety cause. On the other hand, it is a high-yield dilution effect. The milk composition of buffalo milk is relatively higher than that of Holstein milk. In the drinking experience, the water milk will be felt to be thicker.

In view of the inconsistencies in the nutritional data provided by Wang Shi's dairy industry, Prof. Li briefly introduced some of the knowledge about milk milk ingredient research. He pointed out that the detection of milk composition is affected by various factors such as variety, lactation stage, single yield, dietary environment, etc. For example, during the high-yield period, milk will be relatively dilute, the content of nutrient dry matter will be low, and it will be high in the late lactation period. some. This will result in a comparatively large range of nutritional content of buffalo milk and Holstein milk. From the source of data cited by Guangxi's Huangshi Dairy, even though the differences are large and not strict enough, the data are basically from authoritative organizations, and there is no apocryphalization, let alone fraud. In addition, Professor Li suggested that Wong’s milk industry should not lightly quote data. It is better to commission an authoritative organization to conduct a longer period of sampling inspection on the water buffalo milk produced by its own company, obtain the average value, and give the scope of change. This is more scientific. .

In addition to the controversy over nutrient contrasts, in fact, the Internet had previously been circulating over the risk of vitamin A overdose in watermilk, even once caused some people's panic. In this regard, Professor Li believes that it is impossible to give people such experiments. The general laboratory uses mice to do it. This argument is unscientific. Moreover, the food in nature does not say that vitamins can be high enough to make people drink the amount of poisoning. Moreover, in terms of common sense, milk is the food for cattle to feed their young, and it is even less likely.

According to the reporter's previous understanding, buffalo milk has always had a certain degree of recognition in the south. Northerners have generally not drank, and have not even heard it. At present, Wong's milk industry has sold Guangxi's water and milk to Beijing, but the price is rather surprising to the citizens of the capital who first knew the water milk – its price is generally higher than the current high-end milk. Is this price reasonable? What are the reasons for the high price of water buffalo? Professor Li believes there are three main reasons: First, the composition of buffalo milk is higher; second, the yield is scarce; third, the number of dairy cows is also relatively small; may be affected by these factors, the market price of buffalo milk is higher than that of Holstein milk. some.

In the process of communicating with Prof. Li, the author deeply felt the long-term and long-term development of the water-milk industry. As the main measure to solve the shortage of milk sources in the south, buffalo milk has been placed in high hopes by the industry. Moreover, buffalo milk itself is a new type of milk with richer nutrient content. After marketization, it also means a good choice for consumers. However, it is necessary to take into consideration that China's dairy industry has experienced special circumstances after a series of past crises. The public has been sensitive to relevant information. To fully understand and accept milk and milk, more patience is needed for promotion, but special attention must be paid to promotion. Ways and methods to avoid over-emphasis and make the public unclear about water and milk.
