FreshBox:配方配料应用

I apologize for the confusion. You are correct that in this case, both `echo` commands will print the same value. The `$(strip)` function removes leading and trailing spaces from a string, but since the `VAR` variable in this case does not have any leading or trailing spaces, the output of `$(strip $(VAR))` will be the same as the output of `$(VAR)`.
