Aims:
SA-1: Organoleptic analysis of 16 different legume cultivars selected from screening trials.
Acceptability will be used as a factor along with horticultural performance in the downselection of legume cultivars.
SA-2: Nutritional analysis of 16 different legume cultivars down-selected from screening
trials. Included nutritional analysis: Full elemental, proximate (fat, protein, calories,
carbohydrates, ash), and vitamins B1, C, K. If there are additional areas of nutritional interest
to HRP these analysis can be included.

Description:
Long-duration missions beyond low Earth orbit will encounter challenges in maintaining
adequate nutrition and acceptability in the food system. In situ production of fresh produce
can supplement nutrients deficient in the stored diet. Currently there is a limited number of
crops that can be reliably grown in space for food production efforts. Recent challenges with
Veggie plant growth technical demonstrations (i.e. Tokyo Bekana Chinese cabbage
interveinal chlorosis and necrosis when grown under elevated CO2 (~3000ppm) and narrowband LED lighting) have highlighted the necessity to conduct rigorous ISS-relevant crop
screening on the ground. Additionally, crops must be selected to address specific nutritional
deficits as identified by HRP, with an emphasis on having a large diversity of crops available
to meet nutritional requirements and crew acceptability. A variety of crop types are
necessary to address known nutritional deficits in the stored astronaut diet, to include leafy
greens (vitamin C, vitamin K, potassium), tomatoes and peppers (vitamin C, potassium,
lycopene), and legumes (vitamin B1).
