Fresh salmon should be judged by its overall quality—not by color alone. Look for signs of freshness in appearance, texture, smell, and storage conditions.
Here are some key points:
- Bright, moist flesh – The surface should look glossy and slightly moist, not dry or dull.
- Firm texture – Fresh salmon should feel firm and spring back when gently pressed.
- Natural color – Color varies by species and diet. A deeper orange or red does not always mean better quality.
- Clean, fresh smell – Fresh salmon should have a mild ocean-like aroma, not a strong fishy or sour odor.
- Well-defined fat lines – White fat lines should be evenly distributed throughout the flesh.
- Proper refrigeration – Fresh salmon should be displayed on ice or kept under continuous refrigeration.
If you’re buying salmon for raw consumption, choose products that are specifically intended for raw use and have been processed and handled according to local food safety regulations.

挑选新鲜三文鱼时，应综合观察整体品质，而不是只看颜色。新鲜度主要体现在外观、弹性、气味以及保存条件等方面。
可以参考以下几点：
- 鱼肉有光泽、表面湿润——新鲜三文鱼肉质应富有光泽，表面微微湿润，不应发干或暗淡。
- 肉质紧实有弹性——轻轻按压后能够快速回弹，说明新鲜度较好。
- 颜色自然均匀——不同品种和饲养方式的三文鱼颜色会有所不同，颜色越深并不代表品质越高。
- 气味清新——应具有淡淡的海洋气息，不应有明显腥臭味、酸味或异味。
- 脂肪纹理清晰——白色脂肪纹路分布均匀，通常代表肉质状态良好。
- 冷链保存完善——冰鲜三文鱼应全程冷藏，并在展示柜中保持低温保存。
如果是购买用于生食的三文鱼，应选择符合当地食品安全法规、经过规范加工和全程冷链管理的产品，而不要仅凭“新鲜”来判断是否适合生食。
