How to Make a Curdle of a Lime?

Is there a way to find the individual citric malic acid levels of an ingredient, so that we know the amounts to add in order to replicate the acidity ofe components such as limes? I've infused rum with cocoanut cake, cocoanut flakes and pineapple skin. What is the base for the clarified pain killer milk punch? It came out delicious and super clear. But as soon as i had ice or yun keping the fridge, it will go cloudy. Should i fat washi for a milk wash? I wish i'd road ap.
