Question on freezing fresh vegetable purée

Hello. ^_^ This will sound like an odd question, but can you freeze fresh vegetable purée? Let me go into a little more detail . . .

Our dog – our pseudo child – is on an anti-cancer diet recommended by her veterinarian and we supplement her organic kibble every day with puréed organic kale and carrot. (I purée it in my Cuisinart.) Anyway, if I make too much of it in advance, it spoils. So I wonder if I could make a large batch, then freeze part of it. What do you think?

Any help would be greatly appreciated – thank you. ^_^
