Biogenic amines and nucleotide breakdown products of sodium acetate, sodium lactate, and sodium citrate treated seer fish (Scomberomorus commerson) during iced storage

Abstract

The present study communicates the effect of organic acid (2% each sodium acetate [NaA], sodium citrate [NaC], and sodium lactate [NaL]) treatment on the changes in K value and biogenic amines (BAs) during iced storage. Treatment with organic acid improved the sensory quality and extended the shelf life significantly (p less than 0.05). Very low initial K value increased to greater than 66 percentage for all the samples on the day of sensory rejection. Putrescine, cadaverine, and histamine dominated among the BAs. BAs content was observed least for sample treated with NaA. Putrescine level was least for NaA followed by NaC less than NaL less than Control samples throughout the storage period whereas cadeverine and histamine level followed the order NaA less than NaL less than NaC less than control samples. On the day of sensory rejection, Putrescine, cadaverine, and histamine ranged 2.2–10.9, 2.0–11.4, and 3.4–12.7 microgram per gram , respectively. However, throughout the storage period both histamine and total BA content was within the limit prescribed by European commission and US Food and Drug Administration.
