Can egg tart filling be consumed 6 days after opening?

Generally, whether egg tart liquid can be consumed after 6 days of opening depends on the storage method and its quality condition. It may be safe to consume if stored sealed in the refrigerator and shows no signs of spoilage; however, it should not be consumed if left at room temperature or if spoilage has occurred. Detailed analysis is as follows:

If the egg tart liquid is promptly transferred to a sealed container and refrigerated at 0–4°C after opening, and shows no off-odor, clumping, separation, or discoloration after 6 days, it is generally safe to consume. Low temperature slows bacterial growth, and sealing prevents cross-contamination. Thorough heating before consumption is recommended.

If the egg tart liquid was left unsealed and stored at room temperature after opening, or if it develops a sour smell, mold spots, a sticky or clumped texture, or turns grayish in color after 6 days, it should not be consumed. At this point, harmful bacteria may have grown, which could easily cause gastrointestinal discomfort if ingested.

After opening, it is recommended to prepare and consume the egg tart liquid as soon as possible. When refrigerated, it should not be stored for more than 3–4 days. Always ensure it is tightly sealed during storage and kept separate from other foods. Carefully check its quality before consumption and heat thoroughly until fully cooked to ensure food safety.
