Healthy ginseng pudding was made with different doses of two gelling agents and stored at 37℃ for eight weeks. And then quality characteristics and palatability were measured. Sweetness and pH level increased in newly made ginseng puddings but decreased during storage. Acid taste decreased but increased during storage in A (pectin 0.2%+agar 0.6%). But it increased but subsequently decreased in B (agar 0.8%). Acidity in C (agar 1%) remained unchanged until six weeks but slightly increased at 8 weeks of storage. Texture increased in all specimens but subsequently decreased. Chromaticity value of L decreased in all specimens before increasing while the values of a and b increased and subsequently decreased. In texture examination, hardness and adhesion were higher in C (agar 1%) and lower in A (pectin 0.2%+agar 0.6%). There were no differences in elasticity among three specimens. Cohesion was higher in C (agar 1%) while it showed a similar level in A (pectin 0.2%+agar 0.6%) and B(agar 0.8%). Stickiness and chewiness were higher in C(agar 1%) but lower in A(Pectin 0.2%+agar 0.6%), compared with C(agar 1%) specimen. In sensory test, overall palatability was higher in A (Pectin 0.2%+agar 0.6%). In conclusion, ginseng pudding with 0.6% agar and 0.2% pectin exhibited better quality. And ginseng pudding has potential to be developed as healthy dessert considering ample physiological and functional properties.
