TOKYO -- Investors around the globe are hunting for companies that aim to solve the world's food problems with technology, and corporate efforts to reduce food waste offer a juicy opportunity.
Solutions developed in Japan include the use of mold to keep tuna fresh, as well as a sheet made from dried vegetables that can remain edible for two years. Interest in food tech has spiked following the success of Beyond Meat, a U.S. company that makes patties and sausages from soybeans and other plant-based ingredients. The business listed on the Nasdaq in May and now trades at triple its initial closing price.
