This study developed gasiogapidduk to increase the functional value and flavor of traditional Baiksulgi by adding gasiogapi powder. Powdered nonglutinous rice was mixed with powdered leaves (1%, 2%, 3%), powdered stems roots (1%, 3%, 5%), and powdered freeze-dried root extracts (5%, 10%, 15%) of Acanthopanax senticosus, known as the second ginseng, in order to find the combination ratio optimal to the senses. Sensory evaluation and texture characteristic evaluation of gasiogapidduk were used to develop a functional rice cake appealing to the largest number of people. Sensory evaluation consisted of evaluating color, smell, taste and texture, preference quality which reflects overall appeal. Texture characteristics were evalauated on hardness, adhesiveness, cohesiveness, springiness and gumminess. As a result, AE5 mixed with 5% powdered freeze-dried Acanthopanax senticosus extract proved to be the most desirable in both sensory evaluation and texture characteristics.

This study was conducted to examine the effect of emulsifiers on the quality characteristics of Yackwa. Lecithin and various sucrose fatty acid esters (S-570, S-970, S-1570) were used as emulsifiers. The addition of emulsifiers to Yackwa decreased the hardness, cohesiveness, springiness and gumminess, but increased the brittleness. This tendency was most distinct by the addition of S-970. All sensory characteristics of Yackwa such as color, smooth surface, smell, internal layer formation, softness and overall quality, were improved greatly by the addition of emulsifiers. As a result, the mechanical and sensory characteristics of Yackwa were improved by the addition of the emulsifiers, and sucrose fatty acid esters showed better results than lecithin.

This study was performed to examine the effect of various alcoholic drinks used for the preparation of Yakwa dough on the quality characteristics of Yakwa. The effects were compared with the ones prepared with water in terms of expansion ratio, micro-structure, mechanical and sensory characteristics. The dough with alcoholic drinks produced Yakwa samples with increased volume and pores compared with the dough of water. The cohesiveness, springiness, and gumminess were decreased in the samples with alcoholic drinks, but the brittleness was increased. The Yakwa samples with alcoholic drinks were evaluated better in sensory characteristics of nice-smelling, softness, and acceptability compared with the ones of water. There were no differences in the quality of Yakwa among the alcoholic drinks used.

This study investigated the quality characteristics of cookies containing laver powder, which is well known for its various functions and biological activity. This study assessed the quality characteristics of cookies containing various concentrations (0, 2, 4, 6 and 8%) of laver powder(LP). To analyze quality characteristics, pH of dough, moisture content, color, hardness, and sensory properties were measured. Qualities, such as pH, brightness, and redness and yellowness and hardness decreased significantly (p<0.001). The total flavonoid and total polyphenol and ABTS radical scavenging activity were proportionally increased with increasing the level of laver powder added in cookies(p<0.001). The antioxidant activity measured by total flavonoid and total polyphenol activities was significantly higher than control and increased proportionally to the laver powder. The result of sensory test shows that sample group adding 2% of laver powder achieved the highest. Based on the above results, this study suggests that the addition of 2% laver powder may be the best substitution ratio for cookies of the improvement of sensory preference and antioxidant. This study exhibited both the functional and health based benefits of laver when it is added to cookies and confirmed the development feasibility of laver cookies considering consumer satisfaction.

Unique organoleptic characteristics such as rich flavors and chewy texture contribute to the higher popularity of native chicken in many Asian areas, while the commercial broilers are well-accepted due to their fast-growing and higher yields of meat. Sensory attributes of foods are often used to evaluate food eating quality and serve as references during the selection of foods. In this study, a three-phase descriptive sensory study was conducted to evaluate the sensory attributes of commercial broiler (BR) and Taiwan native chicken (TNC) breast meat, and investigate correlations between these sensory attributes and instrumental measurements. The results showed that for the first bite (phase 1), TNC meat had significantly higher moisture release, hardness, springiness, and cohesiveness than BR meat. After chewing for 10 to 12 bites (phase 2), TNC meat presented significantly higher chewdown hardness and meat particle size, whereas BR meat had significantly higher cohesiveness of mass. After swallowing (phase 3), TNC meat had higher chewiness and oily mouthcoat and lower residual loose particles than BR meat. TNC meat also provided more intense chicken flavors. This study clearly demonstrates that descriptive sensory analysis provides more detailed and more objectively information about the sensory attributes of meats from various chicken breeds. Additionally, sensory textural attributes vary between BR and TNC meat, and are highly correlated to the shear force value and collagen content which influence meat eating qualities greatly. The poultry industry and scientists should be able to recognize the sensory characteristics of different chicken meats more clearly. Accordingly, based on the meat's unique sensory and physicochemical characteristics, future work might address how meat from various breeds could best satisfy consumer needs using various cooking methods.

This study investigated the quality characteristics of Yanggaeng with different amounts (in ratios of 0, 1, 2, 4% to the total materials) of tumeric powders. The proximate composition and total polyphenol content, antioxidant activities, Hunter's color values, pH, Brix and sensory properties of tumeric hanging were examined. Results of analysis of the proximate composition analysis showed that ash content was increased significantly by adding turmeric powder and the more content of turmeric powder. The higher content of tumeric powder, the higher total polyphenol and total flavonoids contents. Brix and brightness were lowered and yellowness was increased. The sensory properties were highly rated for the control without turmeric powder in four organoleptic (sensory) properties (taste, texture, odor, acceptance) except color. The group with-1% addition of turmeric powder was highly rated in the second place.

The effects of addition of brown rice flour on the Backsulgies were examined. We chose the addition ratio of brown rice flour as 0%, 50%, 100% along with the pilot study. The addition of brown rice flour did not make significant changes in water-binding capacity, swelling power and the degree of gelatinization. But the addition of brown rice flour had a delaying effect of retrogradation of Backsulgies by textural analysis. In sensory evaluation, the Backsulgi added brown rice flour 50% had the highest value in the overall quality of sensory characteristics. But there was no significant difference in the other sensory characteristics between the 50% and 0% added with. Therefore we concluded that the addition of brown rice flour on Backsulgies improve the sensory characteristics as well as delay the retrogradation and would be a good source of dietary fiber.

The effects of the concentrations of Gardenia blue pigments and sugar types(honey and oligosugar) on the sensory quality characteristics of starch Dasik were investigated to develop a new blue colored starch Dasik. The blueness(-b value) was increased with the increase of blue pigment, while lightness(L value) was decreased. TPA values showed that hardness, fracturability, gumminess and chewiness were increased with the increase of blue pigment significantly(p<0.05), especially in honey-Dasik. In sensory evaluation, honey-Dasik with 0.04%-blue pigment showed higher scores than any other samples, especially in color, sweetness and overall acceptability, but was not significantly different.
