Korean ramyun sodium: how to read the label per pack
MEOKBOGO ORIGINAL · LABEL SCHOOL
A small noodle cup can have more sodium per 100g than Shin Ramyun—and less per pack. Here is how to compare the numbers while shopping in Korea.
Search for a Korean ramyun sodium ranking and you will find plenty of lists. The problem is that the numbers do not always use the same basis. A value for 100g and a value for one whole pack answer different questions.
Before comparing two cups at a convenience store, check both the sodium amount and the amount of food that number describes.
The small cup that changes the ranking
In Meokbogo's August 31, 2026 catalog snapshot, 434 noodle products had nutrition information. Ottogi Cup Noodle spicy rice noodles had the highest sodium figure per 100g in that dataset: 3,069mg.
But that cup weighs 37.8g. The 3,069mg figure describes 100g of the product, not one 37.8g cup. Scaling the catalog value to the pack gives approximately 1,160mg.
Compare that with the 120g bag of Shin Ramyun in the same snapshot. Its catalog figure was 1,492mg per 100g, equivalent to approximately 1,790mg per pack. The order reverses when you compare whole packs.
| Product in the source dataset | Pack weight | Sodium per 100g | Approx. sodium per pack |
|---|---|---|---|
| Ottogi Cup Noodle, spicy rice noodles | 37.8g | 3,069mg | 1,160mg |
| Shin Ramyun, bag | 120g | 1,492mg | 1,790mg |
| Nongshim Yukgaejang Sabalmyeon | 86g | 1,849mg | 1,590mg |
| Nongshim Yukgaejang Big Bowl | 110g | 1,464mg | 1,610mg |
Data: Meokbogo catalog snapshot, August 31, 2026, based on MFDS-filed values. Per-pack amounts are calculated from the displayed per-100g values and pack weights, then rounded. Check the current pack: formats and formulations can differ.
Two useful comparisons, two different questions
Per 100g: how much sodium is present for the same weight of product?
Per pack: how much sodium does this whole pack contain, based on that product's stated weight?
Neither figure makes the other wrong. The mistake is comparing one product's per-100g number with another product's per-pack number.
The conversion
Sodium per pack = sodium per 100g × pack weight ÷ 100
For the 37.8g cup: 3,069 × 37.8 ÷ 100 = 1,160.082mg, or about 1,160mg.
A bigger bowl does not always mean much more sodium
The source article also compares two Yukgaejang formats. The 86g bowl has the higher figure per 100g, but its calculated pack total is about 1,590mg. The 110g Big Bowl has a lower figure per 100g, yet its calculated pack total is about 1,610mg. The whole-pack totals are almost the same.
The original catalog analysis also found many stir-fried and mixed-noodle products around 815–1,022mg per 100g, compared with roughly 1,400–1,500mg for many soup noodles. Those are observations from that dataset, not a rule that every soup-free noodle contains less sodium.
A quick check at the shelf
- Find the sodium line and identify its basis: per 100g, per serving or per pack.
- Check the net weight and the number of servings in the package.
- Compare like with like. Use per-100g figures for equal-weight comparisons, or whole-pack figures when comparing the packs you plan to buy.
- Keep prepared and unprepared weights separate. Adding water changes the weight of the meal; it does not add sodium to the original packet.
These calculations describe the sodium represented by the whole pack. They do not measure how much an individual consumes after leaving broth behind or using only part of a seasoning packet.
