Beer made from bread, and milk made from oats. A pocket-size gluten detector. Fermented coffee beans. Oysters delivered to your door. All of these innovations and dozens of others were on display last weekend at the Food Loves Tech conference, an expo devoted to the future of food and drink. Startups were abundant. The event, hosted by Edible Manhattan and Edible Brooklyn at Industry City in Sunset Park, offered wild variety but consistent themes of sustainability and good health. As the hosts put it, “At best, this data-flooded food culture will mean more traceability, less waste, increased crop diversity, less overeating. Hopefully.” We strolled among the exhibits and bring you a few highlights.
