  • This study was conducted to promote the utilization of fish paste with 0, 2, 3, and 4% added Curcuma aromatica powder. The moisture, crude protein, crude lipid, and crude ash contents of the used Curcuma aromatica powder were 11.15, 6.25, 2.36, and 9.98%, respectively. For the Hunter color values, the L, a values of the fish paste decreased with increasing concentrations of Curcuma aromatica powder, while the b values appreciated. In the folding test, whose results reveal the flexibility of the fish paste, all the test samples showed AA results. In the texture meter test, the hardness, cohesiveness, and springiness increased with increasing concentrations of Curcuma aromatica powder, but the gumminess and brittleness of the fish paste were reduced. In the sensory evaluation, the color and taste of the fish paste with 3% added Curcuma aromatica powder were preferred over those of the other fish pastes. These results suggest that Curcuma aromatica powder can be applied to fish paste to achieve high quality and functionality.

  • Ripened Rubus coreanus Miquel harvested at Gochang was stored for 8 months at $-20{\pm}2^{\circ}C$, and quality changes were investigated at intervals of 2-3 months. Soluble solid concentration increased slightly, but acidity fell during frozen storage. The lightness (L value) and red color index (a value) of ripened R. coreanus Miquel decreased during storage. The vitamin C and ellagic acid contents were 30.79 mg/100 g and $155.12\;{\mu}g/100\;mg$ mg before storage, respectively, but fell to 17.03 mg/100g and $140.11\;{\mu}g/100\;mg$ after 8 months of storage. However, the total anthocyanin content was 39.45 mg/100 g before storage, and this remained unchanged from 2 to 8 months of storage.

  • Quality characteristics of white breads added with different levels of jujube extracts were investigated. Addition of jujube extract significantly decreased L-value, and increased a and b-values. Addition levels up to 70% did not have significant effects on the texture of breads. Significant increases in the hardness, chewiness, and gumminess were observed in 100% jujube-added group. Additive levels over 50% jujube showed good sensory scores compared with control bread in color, flavor, taste, and general palatability. Textural property increased with increasing amount of jujube extract. Results showed substitution of 50-70% jujube extract for water improved bread quality.

  • Initially germinated whole soy flour was investigated for its additional effects on isoflavone contents and some physical properties of Ramyon. The soybeans were germinated at $20^{\circ}C$ for 24 hr. The properties measured were weight, volume, turbidity, color and texture of Ramyon. Addition of the soy flour up to 16% showed a significant increase in isoflavone contents of Ramyon, compared with those corresponding values of mixed wheat-soy flour before Ramyon preparation. The weight and volume of Ramyon and turbidity of boiled water after cooking were markedly increased and the hardness of cooked Ramyon was decreased as the addition ratio of the soy flour goes up. Sensory test showed that savory flavor and yellowish brown of cooked Ramyon were also increased by soy flour addition.

  • The physicochemical, sensory, and functional properties of Codonopsis (C.) lanceolata tea with different amounts of sugar (25%, 50%, 75%, and 100%) were investigated. There were no significant changes in crude protein, crude fat, and ash contents of C. lanceolata tea with different amounts of sugar. In contrast, carbohydrates decreased and moisture content increased in C. lanceolata tea with different amounts of sugar. The natural presumption is that carbohydrates increase with increasing amounts of sugar. In terms of color, the L-value decreased and the b-value increased with increasing amounts of sugar. Although there were no significant changes in total dietary fiber, soluble dietary fiber increased and insoluble dietary fiber decreased with increasing amounts of sugar. The total phenolic and flavonoid content increased, while saponin content remained constant with increasing amounts of sugar. The highest overall acceptability values in the sensory test for color, flavor, taste, and overall preference were 5.77, 5.82, 5.72, and 5.95, respectively, with the addition of 75% sugar.

  • This study was carried out to examine changes in the quality characteristics of unripe peach Jangachi made from different cultivars during storage at room temperature for 60 days. Based on the results, unripe peach Jangachi-showed decreases in pH of pulps and soaking solutions of all varieties during storage. Salinity of Jangachi tended to increase during storage, whereas it decreased in soaking solutions. Soluble solid contents decreased during storage in all varieties, both in pulps and soaking solutions. Among Hunter's color values, L values decreased, a values increased, and b values decreased during storage in all varieties. Hardness decreased for 30 days of storage and increased slightly thereafter. During storage, yeast and mold counts increased and decreased within the range from 2.30~5.55 log CFU/g, respectively. In the sensory evaluation, Madoka and Nagasawa Hakuho were evaluated as good in overall acceptability.

  • The purpose of this study was to investigate the differences in proximate composition, free sugars, amino acids, fatty acids and Hunter color vaules between fresh and odorless garlic. The contents of crude fiber, crude fat and ash in odorless garlic were silmilar to those in fresh garlic. Sugars and crude protein decreased during manufacture of odorless garlic. Among the free sugars, sucrose, maltose and fructose decreased in odorless garlic, while the content of glucose increased. Total amino acid content decreased by about 30% in odorless garlic. Among the amino acids decreased arginine, isoleucine etc. The contents of linoleic acid, palmitic acid and oleic acid were higher than those of other fatty acids in fresh garlic and odorless garlic, but laruric acid was in little quantity. There were no singnificant differences in the Hunter L and b value between the fresh and odorless garlic, but value for greeness(-a) was lower in odorless garlic.

  • This study was conducted to investigate various flavor components of barley meju during fermentation. The change of PH was $5.2{\sim}5.6$. L-value and b-value gradually decreased. a-value gradually increased until fifth day and then decreased. Among 75 flavor compounds identified in barley meju, 10 aldehydes and 10 ketones were most in number followed by 9 acids, 9 phenols, 7 hydrocarbons, 7 alcohols and 6 esters. The contents of ethyl acetate $(67.8{\sim}89.1%)$ was more than those of any ether component followed by hexadecanoic acid $(1.21{\sim}12.00%)$ and tetramethylpyrazine $(0.06{\sim}12.30%$).

  • Strawberry jams were prepared with addition of 1.0 and 2.0% dietary fiber isolated from ascidian (Halocynthia roretzi) tunic for recycling wastes of seafood source and developing new food products. The texture of the jams examined were using a back extrusion rig. All of the rheological parameters decreased in the fiber-enhanced jams. Viscosity profiles were also decreased in the fiber-enhanced jam samples. Hunter L' and a' values increased in the fiber-enhanced jams, accordingly revealing reddish color. As a result of sensory evaluations, the result of taste tests and overall acceptability were significantly acceptable. In the list of acceptability factors, except spreadibility, jam where 1% fiber was added, high sensory scores and preferable acceptability were noted.

  • This study investigated the effect of roasted rice bran (RRB) on bread quality. Bread containing RRB showed small and specific loaf volumes. Baking and cooling loss rates of bread with RRB were lower than bread without RRB. The pH of bread decreased and total titratable acidity increased with increase in the amount of RRB. Water activity (Aw) and moisture contents of bread increased with RRB levels in bread. Bread containing RRB presented lower L value and higher redness (a) and yellowness (b) values. Crumb hardness, springiness, and gumminess increased, whereas cohesiveness decreased upon addition of RRB. Addition of 5% RRB resulted in higher scores in sensory evaluation than the control, however, bread with 15% RRB had the lowest score. Therefore, 5% RRB can be used in bread production.
