The sweet-scented osmanthus pickled in white sugar is generally edible even if it turns black.

Whether the pickled osmanthus can be eaten if it turns black depends on whether the osmanthus has gone bad. If the pickled osmanthus turns black but does not deteriorate, it is just a color change caused by oxidation during the pickling process, the nutrients inside are usually not affected and can generally be eaten.

However, if the pickled osmanthus has been left for too long or has been improperly stored, it has deteriorated, such as mold or odor, causing the color of the osmanthus to turn black, and it cannot be eaten at this time. Mainly because the nutritional value of sweet-scented osmanthus has declined, and the mold that is born will also produce certain toxins. After eating, it may have a certain impact on your health, causing abdominal pain, diarrhea and other adverse symptoms. In severe cases, it may even induce food poisoning. Poisoning, threatening life safety.
