Cricket flour at 40%–50% . It takes approximately 15,500 L of water to produce 1 kg of live animal weight of beef. Out of which only 40% (0.4kg) is edible. Using the same math, this study showed that it takes only 2,500 L of water to produce 0.8kg of edible cricket protein. That means 80% less water is used in order to produce double the amount of final edible product. Cricket flour also promotes sustainability by eliminating the use of traditional grain-based flour (which is oftentimes processed heavily and takes longer to produce). Although cricket flour's nutrition may partially be based on
