Two, look at the texture. Fake lamb rolls texture rough, sliced lean meat, was a large slice; real lamb rolls texture fine, sliced containing white stripes.
Three, look at the fat. Fake lamb rolls fat was a rule row, generally on both sides of the lean meat, color with blood; real lamb rolls fat with uniformity, the color is snow white.
Four, see cooked meat. Fake mutton pot after the color black, a lot of foam, and hard texture; real mutton pot after the color remains pink, less foam, taste nasty and fragrant.
Fifth, look at the fat. Because the melting temperature of mutton oil is higher than lard, when the temperature is lower, the fat of mutton is much harder than the fat of pork.
Sixth, look at the packaging. Some bags will state in the ingredients that those containing other meat ingredients are synthetic meat.
