Abstract:
The preservative effect on the fish of Amomum tsao-ko extract was investigated by soaking the fish in 0.3% Amomum tsao-ko extract and compared with that of 0.3% potassium sorbate solution. The results showed that Amomum tsao-ko extract can significantly inhibit bacterial growth and reproduction in the fish, and slow down the increase of TVB-N and pH values of the fish. In addition, it can lower the decline rate of the sensory quality of the fish. The Amomum tsao-ko extract has similar antibacterial and antioxidant effects to potassium sorbate.
