Document Summary
Created in a lab -- a viable alternative for meat from livestock. Cows raised on an organic farm (three months ago) Extraction of stem cells from a biopsy of two cows. Used cells to grow 20,000 muscle fibers in individual culture wells, each one a tiny hoop of greyish-white protein suspended in a gel- like growth medium that contained antibiotics and a serum extracted from cow foetuses (embryo) After a few weeks of growth, each hoop of fiber was removed by hand, cut open, and straightened out. Then fibers were pressed together, coloured with beetroot juice and mixed with saffron, breadcrumbs, and some binding ingredients to form the burger -- biologically identical to beef, but grown in a lab. Cows are very inefficient -- require 100 g of vegetable protein to produce. End of losing food trying to produce meat.
