Household Ingredients Compared › Frozen seafood (Singapore)

Frozen seafood: what's actually in it?

Frozen seafood in Singapore is mostly plain fish and prawns in a bag — a single ingredient with no list to quote. That makes this the thinnest page in the batch: the FairPrice frozen-seafood shelf (Okeanoss shrimp, Catch salmon and prawns, Snow Treasures cod) is inventoried, but almost none of it carries a retrievable ingredient section, and a plain bag of prawns has no pack list to panel until someone photographs it. One verifiable list is panelled; the rest is an honest inventory gap.

This page does not give a health score or a "best" pick. It shows the ingredient list as printed, with the country of manufacture as printed, and flags added sugar, allergens and additives.

The headline, in 30 seconds

One product panelled. A manufacturer specification for cooked king prawns is the only verbatim frozen-seafood list retrieved in this pass — and it is a UK foodservice specification, flagged as such.
The ingredient that matters most here is the preservative. The panelled prawns list sodium metabisulphite (E223) — a sulphite preservative common on frozen prawns. Plain frozen fish has no equivalent additive.
Plain frozen seafood is a single ingredient. A bag of frozen salmon portions or peeled prawns contains fish or prawns and nothing else — but that still needs a pack photo to panel under this site's rules, and no pack photos were available in this pass.
The FairPrice shelf is inventoried, not panelled. Okeanoss, Catch, Seafood Boy, Snow Treasures and Hai Sia products are listed in seen-but-not-verified with the reason given.

Panelled — frozen seafood

King Prawns, cooked, head-on shell-on — UK foodservice specification, flagged

Pack size: not stated · Made in: Ecuador (as printed)

Ingredients (Erudus manufacturer specification (Sykes Seafood, UK foodservice)): King Prawns (Litopenaeus vannamei) (Crustaceans), Preservative: E223 Sodium Metabisulphite (Sulphites). Contains Crustaceans, Sulphites.

Flag: this is a UK foodservice specification for cooked frozen king prawns, not a Singapore retail pack. It is panelled because it is the only verbatim frozen-prawn list retrieved, and it shows the standard frozen-prawn construction: prawns plus a sulphite preservative. An SG retail pack (Okeanoss, Catch or Seafood Boy) must be photographed before this is presented as an SG list. Country of manufacture: Ecuador (provenance, per specification) Flag: UK foodservice spec, not an SG retail pack Preservative: E223 Allergens: crustaceans, sulphites

Seen but not verified — do not panel until checked

Okeanoss Frozen IQF Shrimp Meat (Tail Off), 400 g — FairPrice-listed, Halal; no ingredient section retrieved.

Findus / Marie frozen salmon ready meals (French) — full lists exist on Open Food Facts, but these are sauced ready meals sold in France, not SG frozen seafood; not panelled.

Nutrition — what the numbers say

All figures in the sortable table are as sold, per 100 g / 100 ml. Click a column header to sort lowest-to-highest, click again for highest-to-lowest; "not stated" always sorts last, because a missing figure is not zero. Per-serving-only figures are in a separate table below and are never sorted against per-100 figures. No Nutri-Grade applies to these foods as non-drinks, except where a drink Nutri-Grade is officially printed — none is quoted or assigned here.

Salt and sodium: salt = sodium × 2.5. The table shows sodium as printed (in mg) with the salt equivalent in brackets. Where the source prints salt only, sodium is shown as salt ÷ 2.5 and flagged as derived. Sodium is not presented as salt, and salt is not presented as sodium.

Total vs added sugars: most Singapore packs list total sugars, not added sugars. A total-sugars figure is never labelled here as "added sugar". Where a source states an added-sugars figure separately, it is noted. The ingredient list remains the evidence for added sugar (sugar, glucose syrup, invert sugar syrup) versus naturally occurring sugars.

Open Food Facts is a community database and is flagged as secondary where used: the pack and the retailer nutrition section take precedence if they disagree. Figures marked "not stated" were not in the source retrieved; they are not estimated, borrowed from another variant, or copied across flavours.

Product	Energy	Protein	Total fat	Saturated fat	Carbohydrate	Sugars	Sodium (salt equiv.)
King Prawns, cooked (foodservice spec)	100 kcal	23 g	1 g	not stated	not stated	not stated	240 mg (salt 0.6 g) — sodium derived from printed salt

Observed numbers, no verdict: One row only: cooked king prawns list 100 kcal and 23 g protein per 100 g, with 0.6 g salt. No comparison is possible within this page.

Seen but not verified (nutrition): no per-100 g nutrition panel was verified in this pass for any FairPrice-listed frozen seafood product (Okeanoss, Catch, Seafood Boy, Snow Treasures, Hai Sia). Their products are not tabled on numbers they do not carry here.

How to read the label — the jargon, in plain English

IQF: Individually Quick Frozen — pieces frozen separately so they do not stick together in the bag.
E223 (sodium metabisulphite): A sulphite preservative used on prawns and other seafood to prevent discolouration. Must be declared; people with sulphite sensitivity should note it.
Vannamei / Litopenaeus vannamei: Whiteleg shrimp, the farmed prawn species behind most frozen prawn meat on the SG shelf.
Dory (Pacific dory): A white fish fillet (Pangasius) sold frozen in cubes and fillets; a different fish from John Dory despite the name.
Tail on / tail off: Whether the prawn's tail fan is left on. Tail-on is for presentation; tail-off is ready to eat.
Live frozen: Prawns frozen alive (or immediately after harvest) rather than cooked first — they still need cooking.

What this page is not

Not a health score, and not a "best" pick. Different products in this category are different products, and this page does not rank them.
Not a taste test, and not a price comparison. Prices change weekly; ingredients change less often, but still change.
Not complete. The products in seen-but-not-verified are not yet panelled, for the verification reasons given, not hidden.

Sources and method

Checked 12 November 2026 from: FairPrice frozen-food and fresh-fish-and-seafood category pages (inventory — Okeanoss, Catch, Seafood Boy, Snow Treasures, Hai Sia listings); Erudus UK foodservice specification for Sykes Seafood cooked king prawns (ingredients, per-100 g nutrition, Ecuador provenance); Open Food Facts French entries for Findus and Marie salmon ready meals (read, not panelled — French sauced meals, not SG frozen seafood). Cold Storage publishes no ingredient list on any product page. Nutrition figures are standardised to per 100 g where the source gives per-100 figures; per-serving-only figures are labelled as such and are not converted; sugars are total sugars as printed, not added sugars, unless the source states added sugars; salt = sodium × 2.5. Where a full pack list could not be verified, the product is in seen-but-not-verified instead of being panelled.
