为什么「天舟二号」带上太空的菜是「鱼香肉丝」和「宫保鸡丁」？

 

「鱼香肉丝」和「宫保鸡丁」能被选中，好吃当然是重要因素，但其实还有更重要的考虑。

"Fish-flavored shredded pork" and "Kung Pao Chicken" can be selected. Of course, deliciousness is an important factor, but there are more important considerations.

太空中没有重力，带骨头、掉渣、掉粉的食物很容易在舱内漂得到处都是，对于航天员来说会非常难处理，还有可能损坏精密仪器。所以糖醋排骨、驴打滚之类的食物就不是很适合。鱼香肉丝和宫保鸡丁没这个问题。

There is no gravity in space, and food with bones, scum, and powder can easily float everywhere in the cabin, which is very difficult for astronauts to handle and may damage precision instruments. So foods such as sweet and sour pork ribs and donkey rolls are not very suitable. Yuxiang shredded pork and Gongbao chicken do not have this problem.

航天食品很大一部分都是以「软罐头」的形式实现常温、长时间保存的。但有些食物，比如新鲜蔬菜，鱼肉之类，如果长时间加热，会失去原来的口感。风味、质构变化都很大。导致最后做出来的不好吃。鱼香肉丝和宫保鸡丁也没这个问题。

A large part of aerospace food is stored in the form of "soft cans" at room temperature and for a long time. But some foods, such as fresh vegetables, fish, etc., will lose their original taste if heated for a long time. The flavor and texture have changed greatly. As a result, the final product is not delicious. Yuxiang pork shreds and Kung Pao chicken do not have this problem.
