I’ve noticed that beef sold in small shops in China is often a bright red color as if very fresh, maybe too fresh. It may have been sitting out for hours or days, and it is still that bright red color, never turning brown as regular beef does. We were buying beef from a local market for quite a while before it hit me that there was something odd about the color. It never turned brown until you cooked it. Finally it hit me that this beef has been treated in some way, probably with sodium nitrite or other chemicals that prevent the normal browning that occurs when beef oxidizes over time.
Some people worry that nitrites might cause cancer, especially when present in meet that is grilled or cooked at high temperature. Whether nitrites are carcinogenic or not, I don’t want chemicals being added to my beef to disguise its age and let old beef look fresh. This might be a good topic for further investigation because I don’t know for sure what is being added and who is doing the treatments, or of they are safe or not. But in the absence of assuring data, the strange absence of browning in some of the been being sold here has given me one more thing to worry about when it comes to meat in China.
Eat meat sparingly. Make sure it’s fresh and from a trustworthy source. Pork and chicken, which are sold in large quantities with high turnover, may be freshest and safest, in my opinion.
