In the market of pork meat dishes, what changes into the meat grinder and the weight? How often does it vary in proportion?
It's usually the same (the law of conservation of mass), but some of it will stick to the machine, or it will be less.
Look, what's the meat grinder? And what's the procedure?
There must be a change. Because you buy pork, meat processing, must be more than a few minutes of water washing, water penetration and attached to the meat, will undoubtedly increase the weight, except myself increase their weight.
