Malossol Explained: What Lightly Salted Caviar Means

Just 3% to 4% salt: that is the traditional malossol range described by University of Florida extension guidance. The Russian word means “little salt”, and it names a lightly salted style of caviar. It is a description, not an exact salt declaration. For a numerical figure, look to the nutrition information, where available, for salt equivalent or sodium.

What malossol tells you about the tin

Malossol describes the salting. It does not identify the fish species, guarantee quality or tell you whether the caviar has been pasteurised. Added preservatives and the use-by date also need their own information. One word cannot do the work of the whole label.

For the distinction between roe and sturgeon caviar, start with what is caviar. To follow how salt is applied and the cure develops, read salting caviar, which explains the processing behind the term.

How much salt do the sources specify?

Read a salt percentage as a proportion of weight: 4% means 4 g in 100 g of finished caviar. The amount of salt added during manufacture is a different measurement. That belongs to the recipe and need not match the salt content of the finished product.

The figures answer different questions. The university describes commercial usage of malossol; Codex and GOST set composition specifications for the products they cover. They are not three competing legal definitions of the word.

What Codex and Russian GOST actually define

Codex specifies the salt content of caviar, not the meaning of malossol. CXS 291-2010, section 2.2, sets 3 to 5 g of salt per 100 g of finished granular sturgeon caviar; the text was last modified in 2026. It neither uses nor defines “malossol”.

Codex is an international reference standard, rather than automatically binding national law. Its composition requirement is separate from the rules governing what a business may claim on a retail label in a particular country.

Russia’s GOST 7442-2017, Granular sturgeon caviar: Specifications, sets the grade-specific ranges shown in the table. It does not define malossol as a named category either. The primary sources cited give no statutory numerical definition of malossol in national law, leaving open whether one exists elsewhere.

Lightly salted still means carefully refrigerated

Less salt can mean a weaker barrier to microbial growth. With other conditions unchanged, reducing salt can shorten shelf life. Salt is only one part of preservation: heat treatment, preservatives, packaging, hygiene and temperature also shape how long caviar keeps.

A 2021 study followed caviar from 12 female white sturgeon, comparing three salt or preservative formulations during storage at -2 °C (28.4 °F). Microbial plate counts differed between treatments. That is why malossol alone cannot tell you a tin’s keeping time. The supplying producer supported the study, which did not test household storage.

At home, follow the producer’s validated storage instructions, use-by date and after-opening limit. Do not calculate a shelf life from the salt percentage. For the preservation mechanisms, see how salt preserves caviar. Heat treatment is a separate distinction, explained in fresh, unpasteurised and pasteurised caviar.

Salt and sodium: read the right number

Salt and sodium are not interchangeable figures. Table salt is sodium chloride; a nutrition label may give either salt equivalent or sodium. For EU and UK nutrition labelling, multiply sodium by 2.5 to calculate salt equivalent. To convert salt equivalent back to sodium, divide by 2.5.

For example, 4 g of labelled salt per 100 g corresponds to 1.6 g of sodium per 100 g. A 15 g serving therefore contains 0.6 g salt equivalent and 240 mg sodium. That 15 g portion, about half an ounce, is the site’s standard serving, not a regulatory serving size.

There is one further distinction worth keeping clear: nutrition-label salt equivalent counts sodium from all sources, not only added sodium chloride. It therefore need not directly measure the curing salt. For dietary context and portion calculations, read salt in caviar.

Find the useful figure on your label

Start with the nutrition panel, not the descriptive wording on the front of the tin. Look for a quantity tied to a clear weight: grams per 100 g, for example, or milligrams per stated serving. “Salt” in the ingredients list tells you it is present, not how much there is.

EU: Regulation (EU) No 1169/2011 generally requires a salt declaration per 100 g in the nutrition information for prepacked foods, subject to exemptions. Use that line to compare products; malossol is not a numerical promise.

The primary sources cited give no statutory numerical definition of malossol in national law, leaving open whether one exists elsewhere.

UK: Great Britain uses its assimilated and amended version of Regulation (EU) No 1169/2011. The EU regulation continues to apply in Northern Ireland. Both systems generally require salt to be declared per 100 g for prepacked foods, with exemptions.

US: Under 21 CFR 101.9, the Nutrition Facts panel generally declares sodium in milligrams per serving, with applicable exemptions. Check the serving weight alongside it. A sodium figure for one portion cannot be compared directly with a salt figure per 100 g.

If there is no figure, ask the supplier for the current product specification. Establish whether any percentage means salt in the finished product or salt added during curing. If only sodium is available, convert it to salt equivalent, then put both products on the same weight basis before comparing them.

If the supplier cannot provide a numerical specification, the tin’s exact salt level remains unknown. Malossol still tells you the intended style: lightly salted caviar. For comparing salt intake or following storage instructions, use the relevant figures and directions rather than the word on the lid.
