If kept consistently cold (below 40°F or 4°C), what diminishes after the four-day window for tamagoyaki?
Answer
Quality, specifically moisture level and texture
Even if tamagoyaki is stored consistently below the critical safety threshold of 40°F or 4°C, ensuring it remains safe to consume beyond the recommended three to four days, the quality will inevitably begin to diminish. The primary components affected are the moisture level and the texture. Eggs are prone to drying out or changing consistency when stored over extended periods, even under ideal cold conditions. Therefore, while safety might technically be maintained longer, the peak flavor and ideal texture are lost after about four days.
