Primary quality indicators for sturgeon white begin with color assessment, where the most prized specimens display a uniform pearl-white to ivory hue, completely free from any grayish or yellowish undertones. The eggs should exhibit perfect symmetry and maintain a consistent size throughout the batch, typically ranging from 2.8 to 3.2 millimeters in diameter. Texture evaluation focuses on firmness and resilience - each egg should maintain its shape when gently pressed while demonstrating a subtle spring-back quality.

The international grading system for sturgeon white employs a three-tier classification: - Grade 1 (Royal): Perfect coloration, uniform size, firm texture, and complete absence of broken eggs or impurities - Grade 2 (Premium): Slight variation in color permitted, minimal size differences, good texture with less than 2% broken eggs - Grade 3 (Classic): Acceptable color variation, noticeable size differences, and up to 5% broken eggs allowed

Authentication of genuine sturgeon white involves both visual inspection and laboratory analysis. Certified graders examine the characteristic "pop" or burst effect when the eggs are pressed against the palate, which should produce a clean, subtle butter-like flavor without any fishy aftertaste. DNA testing is increasingly employed to verify the genetic authenticity of albino sturgeon origin, particularly for high-value shipments.

Moisture content serves as a crucial quality parameter, with optimal levels ranging between 48-52%. Higher moisture content can indicate improper processing or preservation methods, while lower levels might suggest over-maturation or excessive salt treatment. Salt concentration should ideally remain between 3.2-3.8% to maintain both preservation and taste qualities.

Storage conditions significantly impact grading outcomes. Premium sturgeon white must be maintained at a consistent temperature between -2°C and +2°C throughout the supply chain.
