This study was examined the quality characteristics of dough liquid according to the additional ratio of Doraji in seaweed snack manufacturing. Firstly, the results of Doraji type (dry & powder) were as follows: Carbohydrates 77.57~79.29, crude protein 9.10-9.25, crude fat 0.96~1.33 and calories 355~366 kcal, pH 5.42~5.45, sugar $3.53{\sim}3.96^{\circ}brix$, color 33.82~44.25 (L), 2.27~3.52 (B) and total free amino acids 2,200~2,699 mg/100 g. Total polyphenol contents had dry extracts 1,931.18 mg% and powder extract 1,382.43 mg%, DPPH and ABTs radical scavenging activities tended to increase with higher treatment concentration. Next, the results showed that dough liquid for seaweed snack manufacture which was added Doraji were as follows: Color became deep poppy red with increased addition of Doraji. The texture of adhesiveness, cohesiveness, chewiness, and brittleness tended to decrease with addition of Doraji. The springness showed the opposite tendency. Accordingly, these results suggest that 20% of dry Doraji extract is a proper proportion so that it can be added to the rice dough liquid to produce form Doraji (dry and powder) containing seaweed snacks.
