Household Ingredients Compared › Canned Mushrooms and Peas (Singapore)

Canned mushrooms and peas: what's actually in it?

Canned mushrooms and peas are the plainest cans on the shelf: mushroom or peas, water, salt — and sometimes citric acid, sometimes sugar, sometimes a colour. The Singapore shelf is Hosen, Narcissus, Mili, Ayam Brand, FairPrice house brand and Yifon for mushrooms, and Ayam Brand, Hosen and Mili for peas. The real differences are small: whether the peas are 'processed' (rehydrated dried peas, with colouring) or whole garden peas, and whether the mushroom can adds citric or ascorbic acid.

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

The headline, in 30 seconds

Mushroom cans are four ingredients at most. Mili Whole Mushroom is water, mushroom, salt and citric acid; the standard button-mushroom pattern is mushrooms, water, salt, citric acid, sometimes ascorbic acid.
Ayam peas are garden peas with sugar. Ayam Brand Garden Peas are peas 62%, water, salt, sugar — sugar is on the list, where a plain pea can would not have it.
Processed peas are a different product. UK-style processed peas are rehydrated dried peas with colour (copper chlorophyllins, carotenes) — the FairPrice 'Ayam Brand Processed Peas' name signals this style, and the SG pack needs checking against the brand's garden-peas list before the two are treated as one product.
Straw mushrooms are not button mushrooms. Hosen and Narcissus sell unpeeled straw mushrooms as well as whole button mushrooms; they are different species in different cans and are panelled separately.
Origin is usually China. Mili Whole Mushroom states China as country of origin; most other mushroom cans in this category state no origin in the sources retrieved.

Nutrition — what the numbers say

All figures in the first table are as sold, per 100 g / 100 ml. Salt and sodium: salt = sodium × 2.5. The table shows sodium as printed (in mg) with the salt equivalent in brackets. 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-fructose syrup, molasses, honey) versus naturally occurring sugars (fructose in fruit, lactose in milk).

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. No Nutri-Grade is quoted or assigned on this page: Nutri-Grade applies to drinks, and none of these products carries a printed Nutri-Grade on its Singapore pack as verified in this pass.

Product ↕	Energy ↕	Protein ↕	Total fat ↕	Saturated fat ↕	Carbohydrate ↕	Sugars ↕	Sodium (salt equiv.) ↕
Ayam Brand Garden Peas	80 kcal	5.4 g	0.8 g	not stated	10.0 g	1.7 g	200 mg (salt 0.5 g)

Click a column header to sort low to high; click again for high to low. “not stated” always sorts last — it is missing data, not zero.

Conflicts flagged, not silently resolved: Ayam peas — the brand-site product is 'Garden Peas 400g' while FairPrice Singapore lists 'Processed Peas 425g'. Processed peas (rehydrated dried peas, often with colour) and garden peas are different products; until the SG pack is checked, the brand list is panelled under the Garden Peas name only and the SG Processed Peas product stays in seen-but-not-verified. No nutrition conflict: the per-100g figures tabled are from the same brand page as the ingredient list.

Seen but not verified (nutrition):

Mili Whole Mushroom — no nutrition panel verified (a generic whole-button-mushroom spec gives 25 kcal per 100ml, but it is a UK foodservice spec for a different product, so it is not tabled).
Bonduelle Whole Button Mushrooms — no nutrition panel verified in this pass.
Hosen, Narcissus, FairPrice house brand, Mili Straw Mushroom, Mili Green Peas, Hosen Green Peas — no nutrition panels verified.
Hosen Green Peas Choice Whole — per-serving energy 38 kcal per 80g (Fitia SG) noted here only; the rest of its panel was not retrieved.

How to read a canned mushrooms and peas label — the jargon, in plain English

Processed peas: Peas made from rehydrated dried peas, usually with added colour (copper complexes of chlorophyllins, carotenes) to keep them green. Different from garden peas, which are fresh peas canned in water and salt.
Button mushroom vs straw mushroom: Button mushrooms are the familiar white Agaricus bisporus; straw mushrooms (Volvariella) are the smaller, grey-brown mushrooms used in Asian cooking. Different species, different cans.
Citric acid (E330): Acidity regulator in mushroom cans; keeps colour and prevents darkening. Ascorbic acid (E300, vitamin C) is an antioxidant doing a similar job.
Unpeel / unpeeled: Straw mushrooms sold with the outer skin on. 'Unpeel straw mushroom' on Hosen cans means unpeeled straw mushrooms.
Drained weight: The weight of the mushrooms or peas after the brine is drained. Mushroom cans are typically about half brine by weight.

Sources and method

Checked 12 November 2026 from: FairPrice canned vegetables category listing (inventory: Hosen, Narcissus, Mili, Ayam Brand, FairPrice house brand, Yifon, AAA, Yummy Hunter, Clearspring); Chai Huat Hin Grocer SG listing for Mili Whole Mushroom (ingredients, origin China); Ayam Brand official site MY for Garden Peas (ingredients and per-100g nutrition); Open Food Facts for Bonduelle Whole Button Mushrooms (manufacturer-supplied data); Fitia SG for Hosen Green Peas per-serving energy only; ShopMustafa SG canned-food listing (inventory corroboration). Cold Storage publishes no ingredient list on any product page, so its canned mushroom/pea range could not be verified from its site. No pack photos were available for this pass.
