As early as a long time ago, some scholars and some media questioned this OMP, because according to the biochemical data of OMP published on Mengniu's website, it is completely consistent with insulin-like growth factor 1 (abbreviated as IGF- 1) which has been studied in many countries at home and abroad. According to media reports, a patent filed by Mengniu in 2006 also showed that they added IGF- 1 to milk products that "can promote the absorption of calcium by human body". Let's take a look at the regulatory opinion put forward by the General Administration of Quality Supervision, Inspection and Quarantine in the official letter: "In view of the fact that the safety of OMP has not been clearly stipulated in China at present, IGF- 1 substance ... is not included in the use standard of food additives, and if the above substances are artificially added, it does not conform to the provisions of existing laws and regulations. If the enterprise thinks that OMP and IGF- 1 are safe, please ask the enterprise to provide relevant materials directly to the Ministry of Health in accordance with legal procedures and apply to the health department for a decision on whether to allow the use of OMP and IGF- 1. "

Protein content in milk per100g can reach 3.3g, which is13.8% higher than the national standard-this is a big selling point of Telunsu. By using China National Intellectual Property Administration's patent search, the reporter can find three patents applied by Mengniu, namely "osteoblasts milk protein-rich lactic acid bacteria beverage and its production method", "osteoblasts milk protein-rich pasteurized milk and its production method" and "osteoblasts milk protein-rich yogurt and its production method".

In these patent specifications, OMP is introduced as "osteoblasts milk protein", and the standard term of this substance is GFC or growth factor concentrate. The patent specifications indicate that one of the components of GFC is IGF- 1. Mengniu quoted medical research as saying in the patent specification that "IGF- 1 is a paracrine and autocrine factor that regulates the proliferation and function of osteoblasts."

Fang Zhouzi, an academic counterfeiter, said that the amino acid composition, molecular weight and physiological function of OMP published by Mengniu are exactly the same as IGF- 1, and it would not be so coincidental if they are two different protein. The latter is a kind of hormone protein, which also exists naturally in milk, about a few nanograms per milliliter. The human body produces about 10 mg of IGF- 1 0 every day, but according to Mengniu patent, the IGF- 1 added in/kloc-00 grams of Telunsu milk is as high as 5.65 ~/kloc-. IGF-I is harmful to human body, and may even cause epithelial cell cancer, breast cancer, prostate cancer, lung cancer, colon cancer, rectal cancer and other cancers.

Focus of controversy

OMP in milk to the end

Is it IGF-1?

According to Mengniu's product manual, OMP is a kind of milk protein from cow's milk, which helps to form or repair human tissues. IGF-1insulin-like growth factor is a recognized hormone protein, or protein hormone. The FDA approved IGF- 1 for the treatment of diabetes and amyotrophic lateral sclerosis, but it was later revoked because of its great side effects.

Mengniu said that IGF- 1 is only a technical reserve. Unlike OMP, IGF- 1 will not add milk. However, Fang Zhouzi, a scholar, said that the biochemical data of OMP published by Mengniu were completely consistent with IGF- 1.

General milk also contains IGF- 1. However, according to Mengniu patent, the content of IGF- 1 in100g Telunsu milk is as high as 5.65~ 16.8mg, which is tens of thousands of times that of ordinary milk. It is reported that IGF-I may cause a variety of cancers.
