Adding flavor complexity to farmed barramundi
Organoleptic attributes such as flavor and aroma are among the most important factors that influence consumer acceptability and demand for fish products. Consumers have identified farmed fish as less complex and lacking “sealike” or “sea-fresh” flavors and aromas.
