On the internet there are always mentions of the Dutch being guilty of perfecting and accelerating this practice, never bothered to find the truth. Selling water for £10 plus per kilo is the Holy Grail for those outside of the boutique mineral water industry.The white slime that comes out is a brine solution.

The machines are called tenderiser or massagers but all they do is put the meat in a high vacuum chamber and inject brine under pressure using a bank of needles. Chicken breast can be doubled in weight.
