As we all know AOAC methods are methods specific to a certain product, component etc. resulting to its limitations. The question is, can we use this methods for other products? For example, AOAC 942.15 is a method for determining TA values of fruit and fruit products, can we use this method in sauces or products with acetic acid or other products not related to fruit to determine its TA value? Another example is AOAC 935.47, method for determining salt as sodium chloride in meat products, can this method be used in determining salt content as NaCl in other products like powders high in salt?
