If you want to store grapefruit for preservation, you can peel it in half and completely, and then you can seal the leftover grapefruit in the grapefruit skin for preservation. Or you can wrap grapefruit meat with plastic wrap and put it in the refrigerator.
The reason why grapefruit has yellow gum is because grapefruit cells are squeezed and injured during transportation, or grapefruit tissues are damaged by pests and diseases, and tissue fluid oozes out. In this case, grapefruit pulp can be eaten as long as it doesn't change taste or deteriorate, but yellow jelly is sticky and nutritious, so it is not recommended.
Precautions for eating grapefruit
