比较对象应该是protein.
e比较对象不明确, 可以是protein也可以是rice.
所以需要添加that或是does才可以明确比较对象.

与in addition to having...相一致的逻辑主语只能是 rice,这样排除a,c,d.e错误地省略的助动词does,这是绝对不可以的。

in addition to having more protein than wheat has, rice has protein of higher quality than that in wheat , with more of the amino acids essential to the human diet. 将does代替的动词补出来比较关系会比较明显。

另，句末的with是不是独立结构呢？请指教~
