One-third of all food produced for human consumption is wasted producing landfill accumulation and greenhouse gas emissions. Brewers' Spent Grains (BSGs) are the leftover grains from beer production, and each year approximately 30 million tons of BSG is generated globally by the brewing industry. Reclaiming BSG as a potential human food source is an opportunity for reducing food waste in the food supply chain. Six focus groups were conducted using 37 college students to determine their consumption of whole grains, perceptions of whole grains versus refined grains, and interest in or barriers related to consuming and purchasing foods made with BSG...
