"Mechanism of histamine formation and control in fermented viscera ‘dayok’ from yellowfin tuna [Thunnus albacares (Bonnaterre)]."
Dayok is a fermented fish product prepared from tuna viscera. This study aimed to determine the formation and control of histamine in fermented tuna viscera as influenced by different salt concentrations (10, 17.5, and 25%), fermentation ...
