Partitive articles and definite articles

With aimer, the use of the article generalizes the statement:

J'aime les pommes. -- I love apples.

For a particular item, you can use the demonstrative pronoun:

J'aime cette pomme. -- I love this apple.

The partitive article works as expected:

J'aime des pommes. -- I love some apples.

Aimer, Adorer, Préférer and détester are always followed by definite articles le, la, l' or les.   

@Jaya: yes, but only if you are talking about the general (see the examples in my post).

with aimer, adorer, admirer, detester, and préférer use definite articles only.

EX: J'aime les fruits.

   Je deteste la mer.

Jaime les fruits - this is correct
