Fast food hamburgers are around 12% meat, and 50% water.
I've known for years that if you mix blood with beef fat and put it through a food processor three times the cooked product is indistinguishable from meat by consumers, but this was news to me. I think the n means how many of the eight burger brands contained that material.
The purpose of this study is to assess the content of 8 fast food hamburger brands using histologic methods. Eight different brands of hamburgers were evaluated ...
Water content by weight ranged from 37.7% to 62.4% (mean, 49%). Meat content in the hamburgers ranged from 2.1% to 14.8% (median, 12.1%).
A variety of tissue types besides skeletal muscle were observed including connective tissue (n = 8), blood vessels (n = 8), peripheral nerve (n = 8), adipose tissue (n = 7), plant material (n = 4), cartilage (n = 3), and bone (n = 2). In 2 hamburgers, intracellular parasites (Sarcocystis) were identified.
So glad I stopped eating things like that long ago...
I had to look up Sarcocystis... good thing they're killed by cooking meat thoroughly, or by freezing it.
Still, I hope a piece of grilled fast-food chicken contains fewer surprises!
Hot dogs aren't meat either, even if meat is the first ingredient. The average meat content was under 6%.
Meat content ... ranged from 2.9% to 21.2% (median, 5.7%).
