The latest scientific research results on milk microRNA in milk are released in Beijing

Beijing, June 17th, was hosted by Nanjing University and Taizhou National High-tech Industrial Development Zone. The China Dairy Technology Innovation Conference, co-organized by Yili Group, was held in Beijing on the afternoon of the 17th. Xinhuanet.com broadcast live. Professor Zeng Ke, vice president of the School of Life Science at Nanjing University, released and interpreted the latest scientific research results on milk micronuclear acid in milk. He said that the results of the study established the basis for the milk content based on the milk source of milk. The test showed that microRNA is important for milk. The composition of the material, by adding different sequences of microRNA can be made for different ages of dairy products.

Zeng Ke first introduced the latest research results of microRNA in milk, he said, the specific name of this technology is microRNA research in milk and dairy products. Milk is one of the longest-consuming foods, rich in nutrients and vitamins. Despite the rapid development of the milk dairy industry, we still have a relatively low percentage compared with other developed countries. At present, there are mainly Kjeldahl and other methods for the detection of milk quality in the industry, but the industrial nitrogen determination method is not very specific to be able to test the manipulation of milk. Therefore, it is urgent to develop sensitive detection methods to detect the content of raw milk. This method can avoid the possibility of artificial fraud in the future.

Zenko said that there is no doubt that the modern structure of milk plays an important role in the life cycle. Recently, it has been found that there is a very stable microRNA in the serum, and it can be used as an early disease diagnosis by detecting the microRNA in the serum. This discovery has received great attention in foreign countries.

The following is the first technique used in our laboratory for depth testing. It detects microRNAs that appear in the entire gene sequence. It detects 230 microRNAs in milk. The microRNAs in colostrum and milk are roughly the same, but only in colostrum. The content is much higher than in the milk. The expression profile at different stages of cow's milk production can be used as different contents of cow's milk. Here, there are 7 microRNAs that gradually decrease in content as the diluted milk is expressed in the raw milk. Therefore, this expression can be used to reflect the degree of dilution of milk. The 7 microRNAs can screen egg whites or even trihydroammonium ammonia for foreign proteins such as soya milk protein.

There is also a chart for comparison. We use protein quantification. For the liquid milk that was tested for sale, we can see that the 7 microRNAs can express the difference between raw milk and milk. The powdered milk we tested found that infants under 1 year of age and baby formulas older than 1 year old could find that 7 microRNAs could express the difference between the two. It is also enriched in colostrum and raw milk, and microRNAs that can exhibit life function can participate in infant development.

Therefore, we have two conclusions about this technology: first, the results of the study established the basis for milk content based on milk and milk; second, the detection showed that microRNA is an important component of milk, by adding different sequences of microRNAs. Dairy products for different age groups can be produced.
