Signs powdered fish has gone bad
- A smell of rusty, old fish oil and a bitter taste instead of fresh sea-breeze.
- Brown, sticky clumps from absorbed moisture — a damp-spoilage warning.
- An off smell or any visible mould.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store powdered fish
Treat it in three stages, but know it oxidises faster than meat or dairy powders: a sealed pouch keeps for months, an opened container much less, and once mixed into broth it becomes perishable — refrigerate and use it within a couple of days. Because the omega-3 oils turn so fast, store opened powder in the freezer in an airtight container.
