Purpose: The purpose of this experiment was to analyze Wanja made of beef, pork, and an alternative to meat, and examine if a meat alternative can be substituted for Wanja. Methods: Wanja samples were prepared using ground beef, ground pork, and a ground meat alternative (based on beans). These samples were then analyzed for moisture content, pH, sodium content, cooking loss, Hunter's color value, texture, and through sensory evaluation. Results: The beef Wanja showed the highest and the pork Wanja showed the lowest cooking loss (p<0.001). All the Wanja samples changed color after being cooked and except for pork L-value. a-value and b-value were higher in the Wanja alternative (p<0.001). Texture profile analysis (TPA) showed that adhesiveness is the highest in the meat alternative to Wanja (p<0.05). However, springiness and chewiness were not significantly different in the samples. The consumer acceptance test results of the Wanja indicated that the Wanja alternative had a significantly lower odor, taste, overall acceptance (p<0.001), and texture (p<0.05) than the others. Conclusion: This study, therefore, suggests that a meat alternative could be a possible substitute for meat while cooking Korean cuisine. Some theoretical and practical implications and future research directions of this study are discussed.

Purpose: This study compared and analyzed the antioxidant and antimicrobial activities of unripened and ripened black raspberry (Rubus occidentalis) extracts. Methods: Unripened and ripened extracts were prepared with water, 25%, 50%, and 75% ethanol. To estimate in vitro antioxidant activity, total polyphenol, total flavonoid, and total anthocyanin contents were measured and DPPH and ABTS radical and nitric oxide (NO) scavenging activity were analyzed. In addition, antimicrobial activity against pathogenic microorganisms and bronchus disease-inducing bacteria was measured. Results: Total polyphenol and total flavonoid content were higher in unripened than in ripened black raspberry extracts, and total anthocyanin content was higher in ripened extracts. The DPPH and ABTS radical scavenging activity of ripened extracts was also found to be superior to that of the unripened extracts. The NO scavenging activity was found only in unripened extracts. Further, it was confirmed that the unripened extract had a relatively high antimicrobial activity except against K. pneumoniae KCTC 2245 compared to the ripened extract. Conclusion: These results suggest that unripened black raspberry (Rubus occidentalis) extracts have better antioxidant and antimicrobial activity than ripened extract. Thus, unripened black raspberry extracts have a higher potential for development as antimicrobial material such as a natural antioxidant and preservatives.

Purpose: This study examined the quality characteristics and sensory evaluation of pan bread with whole wheat flour substituted by Liriopis tuber powder at different replacement ratios. Methods: Whole wheat pan bread was prepared by substituting 5, 10, and 15% of whole wheat flour with Liriopis tuber powder. The quality characteristics of the bread were analyzed by appearance, weight, volume, height, pH, color, moisture content, and firmness. Additionally, the changes in the moisture content and firmness of bread during storage at 4℃ were determined. A sensory evaluation was also conducted for bread preference, flavor intensity, and purchase intention before and after providing nutritional information about the Liriopis tuber. Results: As the replacement ratio of Liriopis tuber powder in the bread increased, the color of the crust and crumbs of the whole wheat pan bread became darker, and the bread height and volume decreased. The color of the bread showed a decrease in the *L value (brightness) but an increase in *a value (redness) and *b value (yellowness). Also, the firmness of the whole wheat pan bread decreased as the replacement ratio of the Liriopis tuber powder increased. Whole wheat pan bread stored at 4℃ showed a much smaller increase in firmness with 10 and 15% replacement ratios than with 0 and 5% replacement ratios. The sensory evaluation showed the highest bread preference and flavor intensity scores with a 10% replacement of whole wheat flour with Liriopis tuber powder. However, the scores in preference, flavor strength, and purchase intention for the bread with 15% replacement by Liriopis tuber powder were enhanced by providing the nutritional and functional benefits of this powder. Conclusion: The overall quality characteristics demonstrated that 15% replacement of whole wheat flour by Liriopis tuber powder was appropriate based on excellent bread volume and storability. It would thus be possible to manufacture whole wheat pan bread by replacing 15% of the whole wheat flour with Liriopis tuber powder, which scored high on preference parameters for sensory acceptance and health benefits.

Purpose: This study was conducted to contribute to the vitalization of the food industry through the analysis of future food technology for producing alternative proteins. The demand for protein is expected to increase due to population growth, but it may be difficult to match protein production compared to the demand. Methods: Food technology for the production of alternative proteins to meet the demand was examined through paper and patent analysis. Results: Meat production that relies on traditional livestock farming cannot meet the growing protein demand, due to climate change and resource depletion. Alternative protein is a future food technology that can replace the traditional livestock industry, which in turn can revitalize the sustainable food industry and contribute to economic growth. Alternative proteins are mainly classified into cultured meat, edible insects, and alternative vegetable proteins. Cultured meat refers to edible protein obtained by collecting live animal cells and multiplying them using cell engineering technology. Proteins extracted from edible insects may also be used in food material. Plant-based protein alternatives include technology that uses plant-derived proteins to manufacture foods similar to livestock foods such as meat and eggs. Through the analysis of future food technology for alternative proteins, we have attempted to examine the competitiveness of original technology that can replace the traditional livestock industry. Conclusion: The results of this study provided information on the development of new source technologies by combining various food technologies involving cultured meat, edible insects, and vegetable protein as replacements for traditional livestock protein.

Purpose: This study evaluated and compared the characteristics of omija seed oil (OO) with that of commercial corn (CO) and grape seed (GO) oil during storage. Methods: The color and peroxide values, DPPH radical scavenging activities, and fatty acid composition of three oils were compared according to storage periods (0, 7, 14, and 28 days). Results: The OO was brighter and darker yellow compared to the two commercial oils. During storage, the L* and a* values decreased gradually in all three oils, while the b* value increased. The relative peroxide value increased in the early stage of storage and then decreased in both commercial oils, while the peroxide value of OO increased slightly up to the 21st day of storage and then decreased. In comparison, the DPPH radical scavenging activities of OO and GO were lower than that of CO. However, the DPPH radical scavenging activities of the two commercial oils decreased significantly during storage, while that of OO increased gradually up to 21 days of storage and then decreased. Thirteen fatty acids were profiled by GC-MS and their changes were evaluated during storage. There was no significant difference in the content ratio of palmitic acid to linoleic acid (P/L) in three oils during storage, but the P/L of OO was significantly higher than that of CO and GO. Conclusion: OO remained stable during storage, and can therefore be considered for commercial application is expected.

Purpose: This study investigated the sensory characteristics of low-calorie canned tuna, a favorite of Korean consumers and analyzed the relationship between its sensory attributes and consumer preferences. Methods: Five canned tuna products having the highest market share in South Korea were selected. The sensory properties of the products were analyzed using a generic descriptive analysis. A hundred consumers took part in the consumer acceptance test. Results: Twelve descriptors were developed to characterize the tuna products. The packing medium and additional seasoning were the key factors differentiating the canned tuna products. Partial least square regression revealed that umami taste, mouth-coating and redness were the positive drivers for preference, whereas fishy flavor, fishy aftertaste, and lightness were the negative attributes that drove consumers away. Conclusion: This information can be helpful for further producing new canned tuna products.

Purpose: This study was conducted to contribute to the vitalization of the food industry through the analysis of future food technology for producing alternative proteins. The demand for protein is expected to increase due to population growth, but it may be difficult to match protein production compared to the demand. Methods: Food technology for the production of alternative proteins to meet the demand was examined through paper and patent analysis. Results: Meat production that relies on traditional livestock farming cannot meet the growing protein demand, due to climate change and resource depletion. Alternative protein is a future food technology that can replace the traditional livestock industry, which in turn can revitalize the sustainable food industry and contribute to economic growth. Alternative proteins are mainly classified into cultured meat, edible insects, and alternative vegetable proteins. Cultured meat refers to edible protein obtained by collecting live animal cells and multiplying them using cell engineering technology. Proteins extracted from edible insects may also be used in food material. Plant-based protein alternatives include technology that uses plant-derived proteins to manufacture foods similar to livestock foods such as meat and eggs. Through the analysis of future food technology for alternative proteins, we have attempted to examine the competitiveness of original technology that can replace the traditional livestock industry. Conclusion: The results of this study provided information on the development of new source technologies by combining various food technologies involving cultured meat, edible insects, and vegetable protein as replacements for traditional livestock protein.

Purpose: This study evaluated and compared the characteristics of omija seed oil (OO) with that of commercial corn (CO) and grape seed (GO) oil during storage. Methods: The color and peroxide values, DPPH radical scavenging activities, and fatty acid composition of three oils were compared according to storage periods (0, 7, 14, and 28 days). Results: The OO was brighter and darker yellow compared to the two commercial oils. During storage, the L* and a* values decreased gradually in all three oils, while the b* value increased. The relative peroxide value increased in the early stage of storage and then decreased in both commercial oils, while the peroxide value of OO increased slightly up to the 21st day of storage and then decreased. In comparison, the DPPH radical scavenging activities of OO and GO were lower than that of CO. However, the DPPH radical scavenging activities of the two commercial oils decreased significantly during storage, while that of OO increased gradually up to 21 days of storage and then decreased. Thirteen fatty acids were profiled by GC-MS and their changes were evaluated during storage. There was no significant difference in the content ratio of palmitic acid to linoleic acid (P/L) in three oils during storage, but the P/L of OO was significantly higher than that of CO and GO. Conclusion: OO remained stable during storage, and can therefore be considered for commercial application is expected.

Purpose: This study investigated the consumption behavior (positive and negative) of food packing materials and the knowledge level (low, medium and high groups) of endocrine disruptors, among middle school students (n=240) in the Hwaseong region. Methods: This research was conducted between 18 and 22 May, 2015, and was achieved using the questionnaire method. Data were analyzed by applying the chi-square test, t-test and one way ANOVA test. Results: Considering the gender ratio, higer knowledge level was obtained in girls than in boys (p<0.05). Difference of knowledge score by gender was also higher in girls in 4 of the factors evalulated: harmfulness (p<0.05), size of organism and accumulation (p<0.01), excessive using of pesticide in fruit (p<0.05), putting hot foods in plastic materials (p<0.05). Assessment of positive consumption behaviors revealed that girls (3.20 score) showed a higher score in caution of plastics or vinyls when putting hot food than boys (2.89 score, p<0.05). Conversely, evaluation of negative consumption behaviors revealed that boys showed a higher score in eating all the soup of cup ramen (boys 3.07 score, girls 2.54 score, p<0.01) and microwave cooking of cup ramen made of styrofoam (boys 2.19 score, girls 1.91 score, p<0.05). In the comparison of groups for positive consumption behavior by knowledge level, a higher score (3.33) was obtained by the high group in following recipe when using a microwave oven, than the low (2.70 score) and medium (3.17 score) groups (p<0.05). Moreover, the negative consumption behavior of reusing polyethylene terephthalate (PET) bottle to put hot water was higher in the low group (2.15 score) as compared to the medium (1.93 score) and high (1.63 score) groups (p<0.05). Conclusion: Taken together, our results indicated that to induce good consumption behavior of food packing materials, considering the gender need to take precedence when imparting knowledge improvement related to endocrine disruptors.

Purpose: This study investigated the sensory characteristics of low-calorie canned tuna, a favorite of Korean consumers and analyzed the relationship between its sensory attributes and consumer preferences. Methods: Five canned tuna products having the highest market share in South Korea were selected. The sensory properties of the products were analyzed using a generic descriptive analysis. A hundred consumers took part in the consumer acceptance test. Results: Twelve descriptors were developed to characterize the tuna products. The packing medium and additional seasoning were the key factors differentiating the canned tuna products. Partial least square regression revealed that umami taste, mouth-coating and redness were the positive drivers for preference, whereas fishy flavor, fishy aftertaste, and lightness were the negative attributes that drove consumers away. Conclusion: This information can be helpful for further producing new canned tuna products.
