Sweet potato is one of the crops selected for NASA's Advanced Life Support Program for potential long-duration lunar/Mars missions. This article presents recipes of products made from sweet potato and determines the consumer acceptability of products containing from 6% to 20% sweet potato on a dry weight basis. These products were developed for use in nutritious and palatable meals for future space explorers. Sensory evaluation (appearance/color, aroma, texture, flavor/taste, and overall acceptability) studies were conducted to determine the consumer acceptability of vegetarian products made with sweet potato using panelists at NASA/Johnson Space Center in Houston, TX. None of these products including the controls, contained any ingredient of animal origin with the exception of sweet potato pie. A 9-point hedonic scale (9 being like extremely and 1 being dislike extremely) was used to evaluate 10 products and compare them to similar commercially available products used as controls. The products tested were pancakes, waffles, tortillas, bread, pie, pound cake, pasta, vegetable patties, doughnuts, and pretzels. All of the products were either liked moderately or liked slightly with the exception of the sweet potato vegetable patties, which were neither liked nor disliked. Mean comparisons of sensory scores of sweet potato recipes and their controls were accomplished by using the Student t-test. Because of their nutritional adequacy and consumer acceptability, these products are being recommended to NASA's Advanced Life Support Program for inclusion in a vegetarian menu plan designed for lunar/Mars space missions.
红薯是美国国家航空航天局（NASA）先进生命支持计划为潜在的长期月球/火星任务所选的作物之一。本文介绍了用红薯制作的产品食谱，并确定了干重含量为6%至20%的红薯产品的消费者接受度。这些产品是为未来太空探索者的营养美味餐食而开发的。在美国德克萨斯州休斯顿的NASA/约翰逊航天中心，由评审员进行了感官评估（外观/颜色、香气、质地、风味/味道和总体可接受性）研究，以确定用红薯制作的素食产品的消费者接受度。除了红薯派之外，这些产品（包括对照产品）均不含任何动物源性成分。使用9分制享乐量表（9分为极其喜欢，1分为极其不喜欢）对10种产品进行评估，并与用作对照的类似市售产品进行比较。测试的产品有煎饼、华夫饼、玉米饼、面包、派、磅蛋糕、意大利面、蔬菜饼、甜甜圈和椒盐脆饼。除了红薯蔬菜饼既不被喜欢也不被讨厌外，所有产品要么被适度喜欢，要么被轻微喜欢。通过使用学生t检验对红薯食谱及其对照产品进行感官评分的均值比较。由于这些产品营养充足且消费者接受度高，因此建议NASA的先进生命支持计划将其纳入为月球/火星太空任务设计的素食菜单计划中。
