The rarity and delicacy of sturgeon caviar need to be guarded by a container of the same high quality. The sturgeon caviar tin takes "freshness locking, flavor protecting and quality homology" as the core. From material selection, sealing process to detail polishing, every part is controlled by strict standards, just to maximize the retention of the original flavor and nutrition of caviar, highlight the noble texture of high-end ingredients, and adapt to high-end catering, gift giving, family collection and other scenarios, becoming a quality choice for carrying rare delicacies.

　　Strictly selected material quality to protect the authenticity of ingredients. The tank body is made of food-grade 316L stainless steel, which has undergone multiple precision purification processes. The material purity is more than 99.9%, without any harmful heavy metals and impurities precipitated, meeting international food contact safety standards, preventing the penetration of metal odor, perfectly retaining the natural fresh flavor and delicate taste of sturgeon caviar. At the same time, it has super corrosion resistance and oxidation resistance, no rust or deformation during long-term storage, and comprehensively protects food safety.

　　The sealing quality is constantly improved for long-term freshness retention without loss. Adopting military-grade vacuum sealing technology, matched with imported food-grade silicone gaskets, the sealing accuracy reaches the top industry standard, and the vacuum leakage rate is ≤0.0005Pa·m³/s. It can effectively isolate air, moisture and external impurities, inhibit bacterial growth, allow caviar to be stored for a long time in a low-temperature and light-proof environment, lock the plump juice and original nutrition of each caviar, and maintain fresh taste for 12 months, restoring the pure flavor of caviar just after fishing and processing.

　　Detail quality shows ingenuity, balancing texture and convenience. The inner wall of the tank is treated with mirror polishing technology, smooth without dead corners, does not absorb caviar residues, is easy to clean and does not damage the integrity of caviar particles; the tank body adopts matte frosted technology, scratch-resistant, wear-resistant and delicate in texture, with precise engraved logos to highlight high-end style; the tank mouth is designed humanely, opening and closing smoothly without reducing sealing performance, and easy to take. Each caviar tin undergoes three rounds of quality inspection, without flaws and odors, matching the rare value of sturgeon caviar with extreme quality.
