Yes, generally, sweet and sour cucumber preserved by ourselves can be preserved for a long time, but it must be eaten at different times.

1. The concentration of nitrite in fresh pickled vegetables increased within 24 hours and reached the highest within 7 days to 1 month. If pickled for more than a month, it will gradually decrease.

2. Therefore, the newly preserved sweet and sour cucumber should be eaten on the same day as far as possible, and it is not a big problem to eat the next day after being refrigerated in the refrigerator. Never eat when nitrite concentration is high, so as not to cause discomfort.
