When selecting caviar, color stands out as a key indicator of quality. In most cases the product should be uniform in tone, though a bright red hue can appear in some varieties. Equally important is the overall texture and the absence of films or visible blood clots. This practical guidance comes from a technologist working with a prominent caviar producer, who explains how to assess quality and ensure what’s purchased meets expectations.

The first criterion is the appearance of the eggs. The expert notes that the grains should be crumbly, intact, uniform in size, and clean, without any films or clumps. Color variation is acceptable only for certain types like coho salmon or sockeye caviar, where natural color differences reflect species and diet rather than quality issues. (citation: fishery science)
The second criterion is the texture and consistency. When inspecting a jar, listen for any humming or unusual sounds when it is turned over. In glass containers, a large amount of liquid visible around the eggs can give the impression that the eggs are floating, signaling lower-grade raw material. Minor juice may be present, but excessive liquid is a red flag. (citation: quality control guidelines)
Other signs to avoid include foreign ingredients or even large quantities of additives. Poor taste and an unbalanced flavor profile often accompany such caviar. The expert also cautions that some buyers skip the bright color of eggs, mistakenly assuming it indicates artificial coloring. (citation: consumer guidance)
There is a tendency among some buyers to favor a paler or more subdued color, but the expert explains that the product name often denotes a broader family of fish. For example, what is labeled as salmon caviar covers several species: pink salmon eggs are typically bright orange, while trout eggs run paler or even yellow, and coho salmon caviar can display a vivid red. This natural diversity should be understood to avoid unnecessary dye consciousness. (citation: species overview)
For those who doubt the natural origin of the caviar, the expert recommends a simple test: gently pour boiling water over a few eggs at temperatures above 90 degrees Celsius. The natural product tends to turn white and settle, with white flakes forming from protein folding. An artificial product may stain the water, and if the caviar is based on gelatin, it will melt entirely. In such cases, contacting the manufacturer is advisable, and for more definitive results, a laboratory test for the presence of fish DNA can be requested. (citation: quality science)
The discussion closes with practical reassurance for shoppers who want to make an informed purchase, emphasizing sensory cues and basic tests that can be performed at home or in a store before committing to a larger bag or jar. (citation: consumer safety)
What fish is most easily poisoned? This question, sometimes linked to how seafood is handled and stored, underscores the importance of proper sourcing and temperature control in preserving caviar quality and safety. (citation: food safety guidance)
