文摘
- •
Tryptophan (Trp) enhances muscle nutrient content and flesh quality in fish.
- •
Trp-enhanced flesh quality is related to inhibition of muscle oxidation in fish.
- •
The inhibition of muscle oxidation by Trp is due to increases of GSH and GPx.
- •
Muscle GPx activity increasing by Trp refers to Nrf2 and TOR signalling in fish.
- •
The Trp requirements for fish flesh quality were evaluated.
