This invention discloses a method for preparing Iota carrageenan. Using *Euphorbia tirucalli* as raw material, the raw material is washed to remove salt and sand, then alkali-modified in a potassium hydroxide solution. After acid neutralization, the raw material is directly soaked, ground, and ultrasonically extracted. The extract is then homogenized and finely filtered.
