This study attempted to improve frying powder products based on 272 consumers' purchase conditions. Factor analysis by type was conducted on purchase attributes of consumers who purchased frying powder by categorizing them based on five factors-namely, convenience, information, diversity, safety, and economy. Five main factors were divided into four purchase attributes named various pursuit, convenience pursuit, economical pursuit, and inform/safety pursuit. Purchasing status of frying powder products was analyzed according to three independent variables such as age, meal preparation type, and purchase attributes. The top motivation for using frying powder was convenience. According to the importance-satisfaction analysis survey, taste, expiration date, and certification mark were chosen as highly important and high satisfaction characteristics for frying powder (p<0.001), whereas nutrition, oil absorption, adhesiveness, crispiness, origin, and food additives were highly important and low satisfaction characteristics (p<0.001). In the conjoint analysis, crispiness was the most important attribute of fried food.

This study investigated the effects of values towards Korea fair trade coffee consumers upon attitudes and behavioral intentions and verified the moderating effects of ethical consumption consciousness between relationships among values, attitudes and behavioral intentions. A total of 283 data were analyzed for consumers of fair trade coffee residing in Seoul. Structural equation models were used to identify the relationship between the variables. As a result of the analysis, Schwartz (1994)'s 30 value items were factored into four areas: openness to change, self-enhancement, conservation, and self-transcendence. The value of 'self-transcendence' showed a significant positive impact on attitudes toward fair trade coffee, whereas 'openness to change' had a significant negative impact. Positive attitude toward fair trade coffee showed a significant impact on intentions to buy fair trade coffee. In addition, a moderating effect of ethical consumption consciousness between attitude and behavioral intention was found. Limitations and future research directions are also discussed.

The purpose of this study was to analyze the effects of dietary life application according to preferred dietary life education type on quality of life of participants in dietary life education programs and to provide basic data necessary to enhance dietary life education. The results of the analyses conducted to classify the types of preferred dietary life education and types of dietary life application and to verify the validity and reliability of the factors are as follows. In terms of the types of preferred dietary life education, health-oriented type, knowledge-oriented type, and experience-oriented type were derived. In terms of types of dietary life application, proactive application and emotional application were derived. Knowledge-oriented type and experience-oriented type were found to affect proactive application and emotional application in terms of real-life application, and proactive application and emotional application were found to affect quality of life. Therefore, in order to enhance the dietary life education for adults in general, it is necessary to improve accessibility by initiating and promoting various programs along with continuous support from central and local governments. Moreover, in order to increase the real-life application and utilization of such programs, the importance of practical and theoretical education must be recognized, and efforts should be made in training specialized instructors.

Premix frying powders were prepared by supplementation with 0%, 3%, 6%, 9%, or 12% egg white powder. The following quality characteristics of the fried batter were assessed: proximate composition and amino acid content of premix frying powder; viscosity and pick-up ratio of frying batter; moisture content, lipid content, color, texture and DPPH radical scavenging activity; and sensory evaluation items. Addition of egg white powder in place of wheat flour resulted in lower moisture content (p<0.01) and lower carbohydrate content (p<0.001), higher crude protein content (p<0.001), higher ash protein content (p<0.001), and higher amino acid content (p<0.01) in the premix frying powder. Lower viscosity and higher pick-up ratio (p<0.001) of the frying batter were observed. The resultant fritters had the higher moisture content and higher lipid content (p<0.001). They also showed the lighter color, and had lesser redness and yellowness (p<0.001). Considering texture, the fritters were harder, had higher fracturability and higher adhesiveness (p<0.001), lower springiness (p<0.001), were less chewy (p<0.01), and had lower cohesiveness (p<0.001). Examination of DPPH radical scavenging activity showed higher antioxidant activity (p<0.001) upon addition of egg white powder. Sensory evaluation of the fried batters showed the best outcomes for the group containing 6% white egg powder, in terms of appearance (p<0.05), flavor (p<0.001), taste (p<0.01), texture (p<0.01), and overall quality (p<0.001). Based on the results of this research, we postulate that the addition of 6% egg white powder to premix frying powder will not only improve customer preference and product quality but also enhance the nutrition and functionality of the product.

Physicochemical and antioxidant activity characteristics of radish pickles added with different amounts of stevia leaf (0, 1.0, 2.0, and 3.0 g) were investigated. Radish slices ($4{\times}4{\times}4cm$) were salted with NaCl, soaked into pickling solution added with different amounts of stevia leaf, and then stored at $4^{\circ}C$ for 6 months. Throughout the whole storage periods, L and b values of radish pickles increased significantly with increasing amount of stevia leaf, whereas a value decreased. Hardness and strength increased significantly with increasing amount of stevia leaf during the storage period. Antioxidant compound contents and antioxidant activity increased significantly with increasing amount of stevia leaf. These results are expected to be useful in producing stevia leaf radish pickles with antioxidant activity and we propose the manufacture and commercialization of radish pickles added with 2.0 g of stevia leaf.

This study was carried out to evaluate the effects of yam powder addition (0~40%) on the quality characteristics and oxidative stability of yackwa made with rice flour. While most rice flour (34.35%) had a particle size more than $250{\mu}m$, 75% of yam powder had a particle size less than $65{\mu}m$. Width, height, and volume of rice yackwa added with yam powder increased with increasing yam powder content. While L and b values of rice yackwa added with yam powder decreased with increasing yam powder content, a value increased. Hardness and chewiness of rice yackwa added with yam powder increased as storage period increased at $25^{\circ}C$ for 9 days, whereas they decreased with increasing yam powder content. In a discrimination test, brown color, flavor, sweetness, and bitterness increased with increasing yam powder content, whereas hardness decreased. In a preference test, taste, texture, and overall acceptance increased with increasing yam powder content. The acid and thiobarbituric acid (TBA) values of rice yackwa added with yam powder increased as storage period increased. However, acid and TBA values of the treated groups decreased with increasing yam powder content compared to the control group. Although 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activities decreased with increasing storage period, values increased with increasing yam powder content. It was found that yackwa quality, preference, and oxidative stability increased during storage with increasing yam powder content. From these results, addition of 40% yam powder would be the optimal conditions for making rice yackwa.

This study was conducted to investigate the intakes and preferences related to Korean traditional teas in each of the age groups. The survey was conducted from March $9^{th}$ to $23^{rd}$, 2015. The subjects in this study were 642 adults aged more than 20 years that resided in the Seoul and Gyeonggi areas. The health status score was 3.57, and the health concern score was 3.54. The reason for preferring traditional tea was 'health' (40.5%) and 'good taste, color, and aroma' (29.7%). The most important factor in drinking a traditional tea was health (37.1%). Acceptance of each type of traditional tea was ranked in order of 'grain tea', 'fruit tea', 'floral leaf tea', 'assorted tea', 'medical root tea', and 'tonic tea'. A total of 92.8% of respondents said traditional teas should be popularized. Regarding problems for popularization of traditional teas, the most common response was 'not popularized yet' (39.7%). Regarding the method for popularization of traditional teas, the most common response was 'convenience of purchase for ingredients'. As a result, preferences for traditional tea and popularization method were different according to age. It is thus necessary to develop traditional tea products considering the age range.

This study investigated the quality of noodles added with Moringa oleifera leaf powder. Noodles were prepared at ratios of 0% (control), 2%, 4%, 6%, and 8% (w/w) Moringa oleifera leaf powder based on flour weight.

Amino nitrogen content increased with time and the highest content was $580.8{\pm}1.9mg%$ after fermentation for 72 hours at 2% (v/w). Lightness (L value) and yellowness (b value) decreased with time, whereas redness (a value) hardly changed. MK-7 contents increased with time at each inoculum concentration. The highest content was $20.47{\pm}1.53$ after fermeatation for 72 hours at 2%(v/w) and there were no significant differences between 1%(v/w) and 2%(v/w) inoculum concentrations.

We analyzed the mixed culture characteristics of isolated brewing fungi obtained from Korean traditional nuruk for their development as fermentation starters. In a previous study, we selected appropriate fungi strains based on their large fungi bodies and strong enzyme activities. These fungi strains were mixed cultured under various combination of ratios, pHs and temperatures. As a result, total acidities of R. delemar mixed culture media were higher than those of A. oryzae cultured at $20^{\circ}C$ and $37^{\circ}C$. The pHs of A. luchuensis 34-1 and A. oryzae 37-7 as well as R. delemar 58-8 and A. oryzae 37-7 mixed culture media gradually increased with the culture period. On the contrary, total acidities of the mixed culture media gradually decreased. ${\alpha}-Amylase$ activities of R. delemar 26-4 and R. oryzae 82-7 mixed culture media were strong at $20^{\circ}C$ and pH 4, glucoamylase activities of R. delemar 58-8 and A. oryzae 37-7 were strong at $37^{\circ}C$, pH 3 and 1:2 ratio, and acidic protease activities of R. delemar 26-4 and A. oryzae 78-5 were strong at $20^{\circ}C$, pH 4 and 1:4 ratio. This study provides the optimal mixed culture conditions for fermentation starters based on changes in pH and total acidity, favorable enzyme activities, and fungi varieties.
