Why Does Vacuum-Sealed Fish Smell?

Fish contains natural enzymes and bacteria that continue breaking down proteins even when frozen. If not prepped correctly:

• Trapped gases cause "freezer stink"

• Liquid residue accelerates spoilage

• Improper sealing allows air leaks

The fix? Follow these pro techniques used by fishermen and chefs.

Step-by-Step: How to Vacuum Seal Fish Without Smell

1. Pre-Freeze for 1-2 Hours

• Place fish on a tray, uncovered, in the freezer

• Forms a protective "crust" that prevents juices from being sucked into the sealer

2. Pat Dry Thoroughly

• Use paper towels to remove excess moisture

• Wet fish = faster spoilage & sealer damage

3. Double-Bag for Extra Protection

• Use odor-barrier bags (look for FDA-approved polyethylene)

• For strong-smelling fish (like salmon or mackerel), add a baking soda packet between layers

4. Use the Right Vacuum Sealer Setting

• Dry mode for most fish

• Pulse function for delicate fillets (prevents crushing)

5. Label & Freeze Immediately

• Write the date and type of fish

• Store at 0°F (-18°C) or below

🔹 Avoid overpacking (air gaps = freezer burn risk)

FAQ: Vacuum Sealing Fish

❓ Can I vacuum seal raw and cooked fish the same way?

→ No! Cooked fish should be chilled first to avoid steam buildup.

❓ How long does vacuum-sealed fish last?

→ Raw fish: 6-12 months
→ Cooked fish: 3-4 months

❓ Why does my vacuum-sealed fish taste metallic?

→ Cheap bags can transfer flavors. Always use food-grade, BPA-free bags.

Final Verdict

Vacuum sealing fish the right way eliminates smell and extends freshness up to 3x longer than regular storage.

Pro Tip: For best results, pair a high-powered sealer (like the Vakumar 90KPa Pro) with odor-proof bags.
