Serving sizes for longan (dried)
The app gives 30 g as about a quarter cup. It supplies no household measure for 21 g or 28 g in the inspected panels, so those should not be assigned an invented number of pieces.
Tested serving sizes

| 21 g portion | 21 g | Fructose 0.04 g | |

Breakdown for 0.25 cups
Is longan (dried) low FODMAP?
All six indicators are green at the small dried serving. Fructose becomes amber and then red as the portion grows; lactose, mannitol, sorbitol, GOS and fructans remain green. That differs from raw longan, whose larger portions show sorbitol and fructans.
Longan (Dried) and IBS: what to know
For IBS meal planning, the narrow gap between the moderate and high dried portions makes weighing useful. A handful or loosely filled spoon can obscure that difference. A green reference helps assess the ingredient, while your response also depends on the meal and personal tolerance.
Gut-friendly ways to eat longan (dried)
Measure dried longan before adding it to a dessert, porridge or soup. Divide a recipe's dried-fruit quantity by the number of portions actually served. Soaking changes its weight, but this check provides no conversion for rehydrated fruit or a separately tested result for the soaking liquid.
