Dried shaved coconut is generally permissible in Jain food. Since coconuts come from a palm and are not roots or tubers, many Jains use them in daily cooking and in sweets, snacks, and offerings. It’s common in various Jain dishes and prasad, especially in regions where coconut is a staple ingredient. If you are following a specific vrata or sect (Digambar or Shwetambar) that has particular restrictions, you may want to confirm with your local guru, but there are no universal prohibitions against dried coconut in mainstream Jain practice.
