What the heck is meat glue

In all my years cooking I have always believed in high quality produce. My beef is from my trusted wholesaler who brings me the best of the best West Australian beef, farmed locally.

Over the last few years I have had othe suppliers trying to sell me beef "fillet" which has been bound together with meat glue from a few different cuts of meat. This can sometimes be up to $20 a kilo cheaper. But does it taste the same? Look the same? What exactly is meat glue?

The so-called “meat glue enzyme” transglutaminase is used by the meat industry to add value to meat by gluing together smaller scraps into a larger chunk. And it’s not just used to make fake steak—the American Meat Institute estimates that it’s used in about “eight million pounds of meat every year in the United States.” Transglutaminase can be used to cross-link pieces of any type of meat, fish, or meat product, and hence can be used to produce large chunks of virtually intact looking meat or fish out of small meat or fish cuttings. When researchers actually tested for transglutaminase in 20 samples of meat from the supermarket, they found meat glue in only two of the samples—in a sample of salmon and a sample of turkey.

Where does meat glue come from? For decades, the sole commercial source of transglutaminase was from the livers of guinea pigs. Now it can be sourced much cheaper. However, the future of meat glue remains uncertain because of “communication difficulties.”

One of the reasons the industry uses meat glue enzymes is because, “restructured meat can be made from underutilized portions of the carcasses.” For example, you can get away with adding up to 5% tendons to beef, and some people can’t tell the difference.

This has raised food safety concerns. There is a “risk that otherwise discarded leftovers of questionable microbial quality could find their way into the reconstituted meat.”

One can actually take a microscope and see introduced E. coli O157:H7 along the glue lines where meat pieces were enzymatically attached, which shows that the restructuring process can translocate fecal matter surface contamination into the interior of the meat.

Furthermore, people who have problems with gluten may develop problems when ingesting meat treated with the meat glue enzyme, since it functions as an auto-antigen capable of inducing an autoimmune reaction. Many gluten reactions may not actually be to gluten, though.

So with more and more people developing gluten intolerance and the cost of meat sky rocketing will we see more sick people due to gluten in the meat via the meat glue?
It's scary as a lot of suppliers have already been busted such as the large chain sizzler in Australia, their supplier was found to use it.

I personally can easily tell the difference and so no one can sell me cheap crap. But be careful and always question your food. We have to.

Enjoy
