Abstract

Horse mackerel is a popular commercial fish, but it is highly susceptible to spoilage during transportation, storage,

and marketing. Natural and consumer-friendly methods for extending shelf life are of commercial importance. In

this study, treatment of horse mackerel with Oyster Shell Powder (OSP, 1.5%) delayed spoilage of horse mackerel

without changing sensory characteristics. Treatment with OSP retarded the growth of mesophilic and psychrophilic

aerobic bacteria during the cold storage at 2±1°C. The TVB-N and TMA-N levels remained lower (P<0.05) than

control samples. Lesser color change (ΔE) was observed in OSP samples, especially in the later days of cold

storage. The results of this study may be beneficial as a consumer-friendly and environmental practice in

maintaining quality of fish and reducing economic losses.
