The task work began by meal replacement bar and beverage prototypes being developed to meet macronutrient requirements for breakfast and lunch meals, based on current consumption guidelines. Additional food categories were identified as having low nutrient density and commercial food products and new formulations were proposed as replacements. Accelerated shelf life testing was conducted for all products to determine acceptability and general stability. Bars were confirmed to have a 48 to 72 week shelf life while beverages and most category replacements remained stable for 96 weeks. A variety of menus implementing these substitutions in the International Space Station (ISS) Standard Menu were proposed and estimated mass savings ranged from 11%-25%, and packaging savings of 16%-18% when one meal was replaced each day.
