「魚香肉絲」和「宮保雞丁」能被選中，好吃當(dāng)然是重要因素，但其實(shí)還有更重要的考慮。

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

太空中沒有重力，帶骨頭、掉渣、掉粉的食物很容易在艙內(nèi)漂得到處都是，對(duì)于航天員來說會(huì)非常難處理，還有可能損壞精密儀器。所以糖醋排骨、驢打滾之類的食物就不是很適合。魚香肉絲和宮保雞丁沒這個(gè)問題。

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「軟罐頭」的形式實(shí)現(xiàn)常溫、長(zhǎng)時(shí)間保存的。但有些食物，比如新鮮蔬菜，魚肉之類，如果長(zhǎng)時(shí)間加熱，會(huì)失去原來的口感。風(fēng)味、質(zhì)構(gòu)變化都很大。導(dǎo)致最后做出來的不好吃。魚香肉絲和宮保雞丁也沒這個(gè)問題。

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.
