Application of irradiation as pretreatment method in the production of fermented fish paste
Fermented fish paste, an important source of cheap protein in some regions, is one of the most consumed condiments in the Philippines. Two species of fish, dilis (Stolephrus commersonii) and galunggong (Decapterus macrosoma) were subjected to irradiation as pretreatment method prior to production of...

Fermented fish paste, an important source of cheap protein in some regions, is one of the most consumed condiments in the Philippines.
