I bought some doner kebab from the supermarket, and it is pre-cooked. When I re-heat it using oven, I found many white round spots/particles, the size is about 3mm to 5mm in diameter. I attach some pictures below. Figure.1 is from refrigerator before putting into oven. Figure.2 is after baking by oven. Figure.3 and Figure.4 are the pack of container. First I thought it might be fat, but it seems not, because the texture is different from the fat in the ground meat. Also if I take those white particles out and press it, there is no oil from it. So I think it is not fat. Are those worm eggs?
