Bioregenerative life support systems (BLSS) provide self-sufficient food ingredients to support long-term manned missions. It is crucial to transform raw food ingredients that are regenerated in situ in BLSS into nutritional and delectable meals for spacecraft crews. It is in our interest to develop a dietary menu with Chinese characteristics that comprises biomass produced in situ with BLSS regenerated ingredients.
Here we report an optimized Chinese 4-day diet meal plan for 'Lunar Palace 1' that is nutritionally balanced and highly acceptable. The 2900 cal diet menu not only meets the requirements of a balanced diet for crews but also exceeds the recommended levels for most nutrients. Specifically, daily fresh food consumption in our meal plan is 1267 g day , of which 78% is provided by crops and insects regenerated in situ in the BLSS. The meal plan is highly favored by Chinese crews, with acceptability as high as 7.8-8.2 on a 9-point hedonic scale. We further confirmed that our meal plan satisfies crews' basic nutritional needs through a 105-day closed habitation experiment.
In brief, the findings provide new insights for dietary meal plan design in future long-term manned missions. © 2018 Society of Chemical Industry.
生物再生生命保障系统 (BLSS) 提供自给自足的食物成分，以支持长期载人任务。将 BLSS 原位再生的原始食物成分转化为航天机组人员营养美味的餐食至关重要。我们有兴趣开发一种具有中国特色的饮食菜单，其中包含 BLSS 再生成分原位生产的生物质。
在这里，我们报告了一个经过优化的中国 4 天“月宫一号”饮食计划，该计划营养均衡且高度可接受。该 2900 卡路里的饮食菜单不仅满足了机组人员均衡饮食的要求，而且超过了大多数营养素的推荐水平。具体而言，我们的饮食计划中每日新鲜食品的消耗量为 1267 克，其中 78%来自 BLSS 原位再生的作物和昆虫。该饮食计划深受中国机组人员的喜爱，在 9 分快感量表上的接受度高达 7.8-8.2 分。我们通过 105 天的封闭居住实验进一步证实，我们的饮食计划满足了机组人员的基本营养需求。
总之，这些发现为未来长期载人任务中的饮食计划设计提供了新的见解。© 2018 英国化学工程师学会。
