Final product analysis

Quadruplicate samples of all of the batches of the final dried salted products were analysed for moisture, salt and acid-insoluble ash. Moisture contents of 10 9 samples were determined using an infra-red moisture balance (Model MB-10, Chyro Balance Corp., Japan). Salt contents were determined by macerating 25 9 samples in water and measuring the chloride concentration in the filtered solution by titration with silver nitrate using potassium chromate as indicator (Pearson, 1970). Acid-insoluble ash was determined after digesting the total ash in 10% hydrochloric acid (AOAC, 1980a and b).
