The storm of OMP in Telunsu

As early as a long time ago, some scholars and some media questioned this kind of OMP, because according to the biochemical data of OMP published on Mengniu website, it is completely consistent with insulin-like growth factor 1 (abbreviated as IGF- 1) that has been studied in many countries at home and abroad. According to media reports, a patent applied by Mengniu in 2006 also showed that they added IGF- 1 to dairy products, which "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 within the use standard of food additives. If the above substances are artificially added, it does not meet the provisions of current laws and regulations. If the enterprise thinks that OMP and IGF- 1 are safe, please provide relevant materials directly to the Ministry of Health in accordance with legal procedures and apply to the Ministry of Health for a decision on whether to allow OMP and IGF- 1. "

Protein content in milk per 100g 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 "osteoblast milk protein-rich lactic acid bacteria beverage and its production method", "osteoblast milk protein-rich pasteurized milk and its production method" and "osteoblast milk protein-rich yogurt and its production method".

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

Fang, an academic counterfeiter, said that the amino acid composition, molecular weight and physiological function published by Mengniu are exactly the same as those of-1. It wouldn't be so coincidental if they were two different protein. The latter is a kind of hormone protein, which also exists naturally in milk, and it is about a few nanograms per milliliter. The IGF- 1 produced by human body is about 10 mg per day, but according to Mengniu patent, the IGF- 1 added in/kloc-00 grams of Telunsu milk is as high as 5.65 ~/kloc-0.

Focus of controversy

OMP sticks to the end in milk.

Is it IGF- 1?

According to Mengniu's product manual, OMP is a milk protein from milk, which helps to form or repair human tissues. IGF- 1 Insulin-like growth factor is a recognized hormone protein, or the hormone of protein. The FDA once 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 does not add milk. However, the scholar said that the biochemical data released by Mengniu is completely consistent with 1.

General milk also contains IGF- 1. However, according to Mengniu's patent, the content of IGF-100 g of 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.
