A comparative analysis on the shelf life extension of irradiated and non-irradiated roundscad with the influence of salting
Decapterus macrosoma, commonly known as roundscad or "galunggong" was immersed in aqueous solution of 10% grade sodium chloride for 90 minutes and was exposed to four doses. Effects of salting, freezing and irradiation were evaluated using three parameters at periodic intervals of i week....
