be interested in的句型

Question

想像各位大神请教一个问题。To their surprise it was soon being eaten only by vegetarians and those interested in organic foods.英语句型中不应该是those were interested in XXXX吗？为什么是those interested in呢？

Answer 1

To their surprise it was soon being eaten only by vegetarians and those interested in organic foods
这里interested in organic foods是直接过去分词作those的定语，
其实这个是定语从句演变过来的，原句是：
To their surprise it was soon being eaten only by vegetarians and those who were interested in organic foods.
如果加上were的话就要再前面加个who。追问

恩，我明白您的意思了，这里的interested是属于非谓语动词的范畴吧？表示过去发生或被动的意思是吧？

追答

分词作定语也属于非谓语动词范畴
