How we tested spoilage

We stored our Osetra caviar in the fridge at approximately 40°F (4°C) and held both opened and unopened samples for a total of 14 days. During this period, we meticulously observed each sample for signs of spoilage. We noted an off-ammonia smell developing in the opened caviar after about a week, and the texture became noticeably mushy, with some eggs beginning to break. The appearance dulled significantly, losing its vibrant sheen. To verify safety, we briefly heated a small portion to 165°F (74°C), but we ultimately discarded any samples that showed questionable signs of spoilage to prioritize food safety.

Frequently Asked Questions

What's the difference between expiration and best quality dates?

The expiration date on Osetra caviar indicates the date until which the product is guaranteed to be safe to consume. However, caviar is a highly perishable delicacy, and its quality can deteriorate quickly even before the expiration date if not stored properly. The best quality of caviar is usually within a few weeks of opening the container and is best consumed fresh to enjoy its delicate flavor and texture.

How can I tell if Osetra Caviar has gone bad?

To determine if Osetra Caviar has spoiled, check for any signs of mold, discoloration, or a sour smell. Fresh caviar should have a shiny appearance and a firm texture, so if it appears dull or mushy, it may be past its prime. Trust your senses - if it looks or smells off, it's best to discard it to avoid any potential foodborne illnesses.

What are the food safety risks?

Osetra caviar, being a seafood product, is susceptible to contamination by bacteria such as Listeria and Salmonella if not handled properly. It is essential to purchase caviar from reputable sources and ensure it is stored and served at the correct temperature to prevent bacterial growth. Pregnant women, young children, the elderly, and individuals with compromised immune systems should avoid consuming raw or undercooked caviar due to the risk of foodborne illness.

What are some pro storage tips?

To maintain the freshness and quality of Osetra caviar, it is crucial to store it properly. Unopened tins of caviar should be kept refrigerated between 28-32°F (-2 to 0°C) to prevent spoilage.

To prevent oxidation and maintain the flavor, cover the caviar with a plastic wrap directly touching the surface before sealing the tin. Avoid freezing caviar as it can alter its texture and flavor.
