  • To improve the quality of traditional Doeniang, the sea tangle, sea mustard, or anchovy powder were added to soybean paste and matured for 90 days. The quality and sensory evaluation of the Doenjang were analysed. The addition of anchovy showed higher fat and protein contents in the Doenjang. In the mineral contents, the sweet tangle and anchovy addition significantly increased Mg and K contents. The reducing sugar content showed 9.4% in the Doenjang prepared with sweet tangle and anchovy powder than 6.0% of the control. However, the pH and acidity were not showed any significantly difference at the 5% level by Duncan's multiple range test. The amino nitrogen content was 618.7 mg% in the anchovy Doeniang that is higher than 531.1 mg% of the control. The addition of sweet tangle and anchovy to the Doenjang showed higher score in the sensory evaluation.

  • 'Mixing' and 'immersion' $CaCl_{2}$ treatment methods were tested for preparation of bio-degradable films using powders of sea mustard (Undaria pinnatifida) (leaf, stem, and sphorophyll), sweet tanlge (Laminaria japonica), and fusiforme (Hizikia fusiforme) by extracting alginate through acid-alkali extraction method. Except fusiforme powder, flexible, free-standing films were produced by both methods using all marine algae powders tested. Except water solubility (WS), surface color, tensile strength (TS), elongation at break (E), and water vapor permeability (WVP) did not show distinct difference between $CaCl_{2}$, treatment methods. Although TS, WVP, and WS of marine algae powder films were lower than those of alginate films, they indicate potential in application as a new source of bio-degradable packaging materials.

  • A group of 132 pre-school children with a mean age of six years and one month was the subjects of this investigation. These children were members of three nursery schools locating in Kwang-ju city. Each child's mother replied to a questionaire which included 42 food items and 4 questions. The results showed that the food preference of each child was variable and the group as a whole expressed more positive than negative feelings. The average number of foods liked per child was 22.9(range: $7{\sim}42$) among 42 food items. Peach, Apple, Strawberry, Laver, Egg, Tomato, Sweet Potato, Tangerine Orange and Beef were ranked in descending order of 'like' ratings. The average number of foods refused was 4.9 (range: $0{\sim}25$). Onion, Liver, Red Pepper Leaf, Root of Bellflower, Taro, Wild Seasame Leaf, Egg Plant, Cabbage, Water Cress and Bracken were ranked in descending order of 'refuse' ratings. The odor of hurting feelings, the hot taste and the flabby texture were the reasons why the children refused these foods. The average number of foods unexperienced was 4.4 (range: $0{\sim}14$). Kidney, Dried Small Whitebail, Tangle (DA SHI MA), Liver, SA RI Mushroom, Acorn Mook, Dried Fragrant Mushroom, Pine Agaric, Root of Bellflower and Ped Pepper Leaf were ranked in descending order of 'unexperience' ratings. Children's 'like' rating toward total foods was 57.3% and the 'refuse' rating was 11.7%. Among eight food groups, fruits showed the highest favority (91.4%) and mushroom showed the least (25.9%). The difference between male and female in the preference of total foods did not showed significant level. But the difference were significant in those of individual food groups; other vegetables, green and yellow leafy vegetables, mushrooms(above, p.<01), fishes and shellfish and sea weeds (above, p<.05). Children who had experienced meals missed rated 59.1% and 34.1% of these children missed meals once a week. The main reason for maels missed was due to the heavey snacks before meal time. Children who had snacks twice a day rated 45.6%. Main foods used as their snacks were starch foods (Cake, Biscuit, Sweet Potato) and citrous foods (Fruits, Apple, Tangerine).

  • To increase the marketability of Dolsan leaf mustard Kimchi, seasonings were prepared by sea tangle and Lentinus edodes. Gat Kimchi A (GK-A) and Gat Kimchi B (GK-B) were prepared by addition of complex seasoning with Sea tangle (CSS), complex seasoning with Lentinus edodes (CSL), respectively and evaluated the quality characteristics. GK-A contained high minerals and dietary fiber and showed the effect of delaying pH-lowering and acidity-rising. There were no significant differences in salinity test after 70 days. Reducing sugar of test groups was higher than control. During the fermentation, Leuconostoc sp. was grown in GK-A and GK-B than control. Growth of control's Lactobacillus sp. increased 20 days after. Up to 30 days, lightness of control was high. Yellowness were increased browning potential in GK-B, 20 days after. From the initial to 10 days, Hardness of GK-A showed higher than the others. glutamic acid and aspartic acid content of GK-A was higher significantly than the others in the entire fermentation period (p<0.05). At 0, 10, 30 days, sweet-tasty amino acids of GK-A showed a significantly higher level than the others (p<0.05). From 10 days to 40 days of fermentation, the sensory evaluation of GK-A is better than the other groups. Comprehensively reviewed the above results, the conclusion is as follows: CSS made with sea tangle as a main ingredient. GK-A by seasoning the CSS to 90 g GK-A is expected as a new Dolsan leaf mustard products that can provide flavor and nutrition to the consumer at the same time.
