One of the most interesting -- and controversial -- fields in tech these days involves in vitro meat. By growing meat in labs from animal cells, people could eventually wean themselves off their dependence on livestock as a protein source. There are also big environmental and health concerns in industrial meat production, from the run-off and greenhouse gases emanating from toxic manure to the antibiotics used to keep livestock upright. A gaggle of tech entrepreneurs, software developers, butchers, farmers, food industry executives, and health policy wonks are gathering to brainstorm the issue of meat. One of the more interesting proposals to come out of Hack//Meat is from Foodpairing, a food industry research company and app developer. Foodpairing has broken down flavor to its molecular components and has compiled databases that can match the flavor of those ingredients against other completely different ingredients.
