Udon and soba: what's actually in them?

Udon and soba look alike on the shelf but are different noodles: udon is thick wheat noodles with salt; soba is buckwheat noodles — and most dried "soba" is mostly wheat flour, with buckwheat second. Hakubaku's organic soba is 69% wheat flour and 29% buckwheat flour; its cha soba is 97% wheat flour with just 2% green tea powder and 1% buckwheat. The salt is the other quiet difference: udon carries 4% salt, soba 2%.

Nutrition — what the numbers say

All figures are per 100g, as sold (dried, uncooked). Udon nutrition was not retrieved — its row is absent rather than filled from soba.

Salt and sodium: salt = sodium × 2.5. The table shows sodium as printed (in mg) with the salt equivalent in brackets. Where a source printed salt only, the sodium figure is salt ÷ 2.5 and is flagged as computed.

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.

Click a column header to sort low-to-high, click again for high-to-low. Rows marked "not stated" always sort last — a dash is missing data, not zero. 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 applies to these foods as non-drinks, and none is quoted or assigned here.

Observed numbers, no verdict: Soba lists salt 2.23 g per 100g (sodium 892 mg, computed) while cha soba lists sodium under 5 mg per 100g — the two differ by nearly 200-fold on sodium, which follows directly from their ingredient lists (soba lists salt 2%; cha soba lists no salt). Sugars are 0.78 g (soba) and 4.6 g (cha soba) per 100g, total sugars as printed.

Conflicts flagged, not silently resolved: Cha soba: two secondary sources disagree. The table follows the Asian retailer listing (336 kcal, protein 12 g, fat 1.3 g, carbohydrate 65.8 g, sugars 4.6 g, sodium under 5 mg per 100g). An EU retailer listing for the same product gives 353 kcal, protein 11.4 g, fat 0.9 g, saturated fat 0.2 g, carbohydrate 72 g, sugars 0.2 g, salt 0.007 g per 100g, and an Australian retailer gives 1,406 kJ with protein 12.0 g, fat 1.3 g, carbohydrate 65.8 g per 100g. The sugars figure (0.2 g vs 4.6 g) is the sharpest disagreement — the SG pack must settle it before publish.

Seen but not verified (nutrition): Hakubaku Organic Udon Noodle; Hime Noodles — Udon; frozen udon (all brands). No nutrition panel was retrieved for any of these.

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

Soba
Japanese buckwheat noodles. Dried soba is usually a wheat–buckwheat blend; the buckwheat percentage (29% here) is the number that matters, and 100% buckwheat soba (juwari) is a different, rarer product.
Cha soba
Soba with green tea (cha) powder mixed into the dough. In Hakubaku's version the tea is 2% and buckwheat 1% — the name describes the tea, not a high buckwheat share.
Udon
Thick Japanese wheat noodles. Dried udon is wheat flour, salt and water; the 4% salt here is part of the dough, not a seasoning added later.
Somen / ramen
Thinner wheat noodles (somen) and Chinese-style alkaline noodles (ramen). Hakubaku sells both alongside udon and soba, but they are separate noodle types and are not panelled on this page.
