1. The major components of Omija were found as moisture (16.12%) crude fat (10.5%) crude protein (8.66%) crude ash (3.47%) reducing sugar (5.32%). 2. Omija jelly receipe were summarized as follow; (1) 5% of gelatin concentration was shown to be the most desirable. (2) 15% of sugar concentration was shown to be the most desirable. (3) 12, 15, 18 hrs. of extract time was not significantly different in Omija extract. (4) It was the most desirable for 30g of Omija to boil during 30 minutes in boiling Omija extract. 3. Result of Omija jelly by Instron that Hardness, Adhesiveness, Gumminess tend to increase as the addition level of gelatin concentration increased but Cohesiveness was changed irregularly. 4. Hardness Adhesiveness tend to increase as the addition level of increase as the addition level of sugar concentration increased but Cohesiveness Gumminess was not significant difference. 5. Hardness, Adhesiveness tend to increase as the addition level of extract time increased, but Cohesiveness, Gumminess was not significant difference. 6. Color value of Omija jelly (gelatin 5%, sugar 15%, 18hr. extract) was shown x=7.94±0.047, y=4.24±0.047, z=6.34±0.067 in Omija extract and Omija jelly (gelatin 5%, sugar 15%, Omija 50g, 30 minutes boiling) was shown x=7.76±0.038, y=3.88±0.02, z=6.12±0.021 in boiling Omija extract. 7. Appearance of Omija jelly had significant relationship with Cohesiveness by gelatin concentration and texture of Omija jelly had significant relationship with Adhesiveness by gelatin concentration. 8. Appearance of Omija jelly had significant relationship with Cohesiveness and texture of Omija jelly had significant relationship with Gumminess by boiling Omija extract.
