Characterizing the Quality of Salted Mackerel Prepared with Deep Seawater

This study investigated the quality of salted mackerel prepared with deep seawater concentrate and salt. The quality of the salted mackerel product prepared with deep seawater was compared to that prepared with surface and intermediate seawater salts, sun-dried salt, and refined salt. After preparing the salted mackerel products using the five salts, the products were stored at $4^{\circ}C$ for 35 days. Quality characteristics compared were the acid value (AV), peroxide value (POV), lipophilic browning, volatile basic nitrogen (VBN), pH, viable cell count, and sensory factors. The deep seawater salted mackerel product had the lowest AV, POV, browning value, and viable cell counts, compared to the others, while it had the highest score in the sensory evaluation.
