본 연구는 저지방 소시지의 개발을 위해 밤가루의 지방대체 기능을 평가하기 위하여 실시하였다. 실 험 1은 우선 모델 소시지를 제조하여 지방대체재로써 Soy protein isolate(SPI)와 Konjac flour(KF)를 혼합 사용한 것은 SPI 단독 처리구에 비해 조직감(경도, 검성, 저작성)에서 낮은 값을 보였지만, 지방과 단백질 함량이 높고 수분 함량은 낮은 값을 보였다(p<0.05). 또한 SPI 단독 처리구는 SPI+KF 복합처 리구에 비해 유리수분량이 높은 결과를 나타내었다. 한편 밤가루의 첨가는 조직감(경도, 검성)이 유의적 으로 높아지는 결과를 나타내었다. 실험 2는 지방대체재로써 SPI를 단독으로 사용하고 밤가루의 첨가가 가열 방법의 차이(자비, 훈연)에 따른 효율성을 평가하기 위해 실험을 실시하였다. 자비 소시지는 훈연 소시지에 비해 명도가 높고, 수분 함량이 높았지만, 조직감(경도, 검성, 저작성, 응집성)이 낮게 측정되 었다. 또한 자비 소시지는 훈연 소시지에 비해 가열감량이 적었지만, 유리수분양은 많았다. 제품 소시 지에 밤가루의 첨가는 조직감 중 저작성이 증가하는 경향을 나타내었다.

In this study, pH, oBrix, salt concentration, sodium content, color, hardness, and sensory evaluations were measured during storage at low temperatures for 21 days after making tongue sole Jangajji with different types of Gochujang sauces. The pH was higher than those of samples not containing Maesil fermented liquor at all storage periods. The oBrix of the Maesil fermented liquor added samples was higher than that of the samples not added at the early stages of storage. On the other hand, there was no significant difference between the samples with and without Maesil fermented liquor at the later stages of storage. The sodium content was lower than that of the samples not containing Maesil fermented liquor. The lightness (L) was lower in the early stages of storage than those of the Maesil fermented liquor. In the late stage of storage, however, the lightness was higher than those of the samples not containing Maesil fermented liquor. The redness (a) of the GRWO sample group showed the highest value at all storage periods compared to the other sample groups. The yellowness (b) of the GRWO sample group was high at the early stages of storage. On the 21st day of storage, however, the GRW sample group was significantly higher (p<0.01). The hardness results showed that the value of the later storage period was lower than that at the initial storage stage. The sensory evaluation showed that the Maesil fermented liquor reduced the spicy, salty, bitter, and unpleasant taste. As a result of the acceptance test, the GRWO and GRW samples were evaluated as the acceptance group with color, aroma, texture and overall acceptability compared to the brown rice Gochujang sample group.

규산 시비가 토마토 플러그 묘소질에 미치는 영향과 묘의 저온저장시 규산의 저온장해 경감효과를 검토하였다. ‘Rapito’품종을 공시하여 30일간 32구 규격의 플러그 트레이에서 육묘한 뒤, 여섯 개의 규산 처리 농도구 (8, 16, 32, 64, 128 및 256mM)를 설계하여 20일 동안 주 2회 관주 처리한 뒤, 묘소질을 대조구와 비교하였다. 처리 농도는 16mM과 32mM 처리가 초장, 엽면적, 생체중, T/R율 및 근권부 발육 등 대부분의 생육 지표에서 타 처리구에 비해 양호했으며, 특히 16mM의 농도에서 가장 좋은 묘소질을 보였으나, 64mM 이상의 고농도에서는 대조구에 비해 전반적으로 생육이 억제되는 경향을 보였다. 토마토 묘의 생리적 반응에서 엽온에서는 처리구별 차이가 나타나지 않았으나, 증산율은 32mM이상의 농도 처리구에서 기공확산 저항이 증가하면서 증산율이 감소되는 경향을 보였다. 또한, 처리 횟수에 따른 효과를 검토하기 위해 16mM농도의 규산을 20 일 동안 6, 10, 20회 관주처리 한 결과, 대부분의 생육지표에서 처리 횟수간에는 큰 차이가 없었으나, 무처리구에 비해 묘소질이 향상되었으며, 특히 뿌리표면적, 근장, root tip수등 근권부의 생육이 현저히 증가하였다. 아울러 규산처리가 저온저장시 토마토 묘의 저온장해를 감소시키는 효과가 있음을 확인하였다.

The Chinese fashion market, which has typically been dominated by luxury brands, is expanding more into mid- to low-end fashion brands including global SPA (Specialty retailer of private label apparel) brands. This change in the Chinese fashion market is due to the growth of the middle class in China. The advance of the Chinese middle class is attributed to the fact that the wages of large city workers is improving due to the development of various industries, particularly IT. Recently, the Chinese government has initiated an anti-corruption movement, which has led to the prohibition of luxury goods consumption, and so the interest of Chinese potential fashion consumers has moved to the mid-to low-end fashion products imported from developed countries. In addition, young Chinese consumers' positive attitude toward online shopping is favorable for foreign mid-to low-end brands. These changes in the tastes of Chinese fashion consumers are favorable for Korean fashion brands in particular for several reasons. First, the Korean fashion industry does not have a history of producing luxury brands, but does produce many good mid- to low-end fashion brands. In addition, Chinese tend to consider Korean fashion and food culture as more developed and preferable due to the success of the Korean wave. Lastly, it is easy for Korean practitioners to offer online shopping and customer service. The emergence of mid- to low-end fashion brands started in Korea in the late 2000s when global SPA brands entered the market. Unlike Korea's soho brands, which are based on the "No-brand" strategy, global SPA brands have actually shaken up the market by offering reasonable prices for Korean domestic brand products that are of similar quality. Since then, consumers’ willingness to pay for clothing has been reduced even further in the Korean market even though the low-growth trend in the economy has stabilized. So, it is very important to analyze and study the consumption tendency for low and mid-priced fashion brands among both Chinese and Korean consumers. The purpose of this study was to investigate how Chinese and Korean consumers perceive the personality of mid- and low-priced fashion brands and how such personality affects brand loyalty, commitment, and perceived quality. Brand personality is a vital area of research since fashion products are a type of consumer good that is consumed by users close to the body and which can express the self and the personality to others. Aaker (1997) developed a brand personality measurement scale consisting of five dimensions which many researchers have used in exploring the brand personality dimension in various industries. In the study of fashion in particular, the dimension of brand personality has been explored and its effects have been analyzed. However, most of the research has focused on luxury or high priced brands. Also, the research has not compared cultures such as China and Korea in this regard. Therefore, this study explored how Chinese and Korean consumers perceive some of the mid- to low-end priced brands originating in Europe and Korea. Also, the research examined how multiple dimensions of brand personality affected perceived quality, commitment, and brand loyalty. This study assumed that perceived quality and commitment may mediate the relationship between brand personality dimensions and loyalty. In order to conduct quantitative research, this study adopted scales from the previous literature to measure the variables used in the research model. A professional online research company conducted the survey, which was designed to be administered only to potential consumers of mid-and low-priced fashion brands who had purchased one or both European and Korean brands which were suggested in the survey. Also, gender (female), residential area (Seoul, Beijing, Shanghai), and age (21-39 years old) were controlled for. In this research, the European origin brand was the global SPA (Zara, H & M, ONLY), and there were eight Korean brands, including “Style Nanda,” which is popular in China (Refer to Table 1). The data collected on the 250 Korean and 250 Chinese participants were analyzed using statistical package SPSS 20.0. The brand personality dimension was explored using factor analysis which applied Varimax rotation based on the principle component method. As a result, even though the items included were found to be somewhat different according to the country and origin of the brand, the brand personality dimensions of the European global brands turned out to be similar and reflected “TRENDY, SINCERITY, AND COMPETENCE.” Also, Chinese consumers’ perception of brand personality in Korean brands was found to be similar to their perception of European brands. However, Korean consumers’ perception of Korean brands, which are of course their own brands, was more diverse reflecting “TRENDY, SINCERITY, COMPETENCE, AND OUTGOING.” This seems to be because Korean consumers may have had more chance to experience Korean brands either online or offline through visiting stores or being exposed to a variety of marketing communications. Thus, because there are more Korean brands than European, Korean consumers may be able to have an accurate perception of the personality of Korean brands. The conceptual model of the current research includes the relationships among multiple dimensions of brand personality in perceived quality, commitment, and loyalty. Also, the mediating effect of quality and commitment between brand personality and loyalty was examined. In order to test the hypotheses, hierarchical multiple regression using SPSS was analyzed and is described in Table 2 in relation to European brands and in Table 3 in relation to Korean brands. As expected, brand personality dimensions that were found to be a significant factor in perceived quality, commitment, and loyalty were likely to vary based on Chinese or Korean perceptions. For Korean consumers’ perception of global brands, while TRENDY was likely to be the most powerful personality dimension forming brand loyalty, its impact on loyalty seemed not to be mediated by quality but rather by commitment. Also, the influences of COMPETENCE on loyalty were mediated by quality and commitment. For Chinese consumers’ perception of global brands, the impacts of SINCERITY as well as TRENDY on loyalty were found to be mediated by quality and commitment. In addition, COMPETENCE seemed to have a rather direct impact on quality, commitment, and loyalty without a mediating effect. For local brands, Korean consumers did not seem to rely on brand personality or commitment when considering brand loyalty. Since the R2 did not improve at all with adding mediating factors such as quality and commitment, there was found to be no mediating effects in the Korean cases for local brands. In particular, while TRENDY directly impacted loyalty, OUTGOING was found to be significant only in its impact on quality. On the other hand, all three dimensions of local brand personality turned out to be significant influencers on loyalty and quality for Chinese consumers. The impact of TRENDY and COMPETENCE on loyalty seems to be mediated by quality and commitment. In this study, we found that mid- to low-end fashion brands seemed to reflect valid brand personality according to the brand’s origin (global vs. local) as well as consumers’ culture (Chinese vs. Korean). Also, the effect of brand personality dimension was different. This study contributes to the study of brand personality and the Chinese fashion market by comparing a conceptual model of the consumption behavior of Chinese and Korean consumers in relation to mid and low-priced fashion brands and brand awareness formation. In particular, the research revealed differences between Chinese and Korean consumers, suggesting different approaches for Korean fashion practitioners who are planning on entering China, which has not only a similar market to that of Korea but also one that is familiar to Korean practitioners.

Vegetables and fruits contain a great deal of vitamins, minerals, dietary fiber and phytochemicals. Therefore, healthconcious consumer prefer beverage made from fresh fruits and vegetables due to their health benefits. This study was conducted to investigate differences in nutritional composition and sensory characteristics of juices depending on the apparatus used: either a low-speed juicer or high-speed blender. All ingredients could be made into juice without addition of water using the low speed juicer. However, addition of water was necessary to produce juice with the high-speed blender. Phenol and flavonoid content, were higher in juice made with the low-speed juicer than that produced with the high-speed blender and were correlated with DPPH radical scavenging ability. Protease activity of pineapples juices was not significantly different for the two methods, but protease activity of kiwi juice was about 8 times higher in juice made with low-speed juicer than that made with the high-speed blender. SOD activity also tended to be higher in the juice made with low-speed juicer. The concentration of dissolved oxygen in the juice made with high-speed blender was higher than that of juice made with a low-speed juicer and was correlated with color change. In addition, the high-speed blender caused an increase juice temperature, but temperature was not changed during use of the low-speed juicer. The noise level of the low-speed juicer was low, but the high-speed blender had high noise intensity comparable to that of railway or aircraft noise. In the sensory evaluation of juice, juice made with the low-speed juicer was preferred over juice made with the high-speed blender. As a result, the overall quality of the juice produced using the low-speed juicer was superior.

In this study, the physicochemical and sensory characteristics of low-salt Myungran jeotkal (Alaskan pollock roe) were evaluated after fermentation at 4℃ and 20℃ with or without the addition of deep sea water, salt from deep sea water, and vegetable-origin lactic acid bacteria (Lactobacillus fermentum JS, LBF). When fermented at 20℃, the addition of LBF to Myungran jeotkal resulted in a slow increase in lactic acid content, followed by an abrupt increase after five days of fermentation. However, when fermented at 4℃, the lactic acid content did not change significantly. Further, when Myungran jeotkal fermented at 4℃, the pH decreased as lactic acid production increased. The salinity of Myungran jeotkal fermented at 4℃ and 20℃ was 7% and was not affected by fermentation period. When fermented at 20℃, volatile basic nitrogen and amino nitrogen contents increased with increasing duration of fermentation. Further, volatile acid content decreased, however, the content of amino nitrogen increased after 11 days of fermentation with LBF and no salt effects were observed. When fermented at 20℃ for 13 days, preference (sensory evaluation) was the highest in all experimental groups after 9 days of fermentation, and then decreased as the fermentation period increased. The free amino acid content was highest (1,648.8 mg/100 g) in Myungran jeotkal when sun-dried salt and LBF were added, 2.3 times higher than in the control.

This study investigated the quality change of strip loin from hanwoo with quality grade 2 produced by dry aging, and compared the quality of dry-aged strip loin with that of strip loin from hanwoo with quality grade 1+. Hanwoo strip loins with quality grade 1+ (SL1) and 2 (SL2) after a day of slaughter and dry-aged strip loin (DSL2) aged for 21 days at 2℃ with 85% humidity were obtained from local markets. The proximate composition, pH, cooking loss, lipid oxidation, instrumental color (CIE L*, a* and b* value) and sensory properties of the strip loins were measured. DSL2 contained low moisture and high protein contents compared with SL2, and low fat, high protein, and high ash contents compared with SL1 (p<0.05). The pH and cooking loss were higher and lower, respectively, in DSL2 compared to SL2 (p<0.05). SL1 had a higher pH than DSL2 (p<0.05). However, the cooking loss was not different between SL1 and DSL2. The TBARS value was the highest in DSL2 and the lowest in SL2 (p<0.05). DSL2 had higher L* and b* value compared with SL2 (p<0.05). There were no significant differences of L*, a* and b* values between DSL2 and SL1. Sensory properties such as the color, flavor, taste, texture, and acceptability of DSL2 were higher than those of SL2 (p<0.05). There was no significant different in all sensory properties between DSL2 and SL1. According to the results, dry aging can improve the nutritional and sensorial quality of strip loin with quality grade 2 to quality comparable to quality grade 1+.

This study was carried out to investigate the quality characteristics of low-salt kimchi with salt partially replaced by Salicornia herbacea L. powder (SH). We prepared kimchi with seasonings in which salt was replaced by 0% (S00), 10% (S10), 20% (S20) and 30% (S30) SH. The salinity level of kimchi was about 1%, and there was no significant difference between the experimental groups. Although lactic acid bacterial numbers of kimchi replaced with SH (S10~S30) increased significantly compared to those of control (S00), the pH and titratable acidity of kimchi replaced with SH were not significantly different. Hardness of kimchi tended to increase as fermentation progressed and with SH addition. The results of the sensory evaluation corroborated the physicochemical characteristics. Furthermore, the sensory characteristics of kimchi were not significantly different upon addition of SH. The physicochemical and sensory characteristics of kimchi were not significantly different despite replacement of salt in kimchi seasoning by SH up to 10%.

본 연구는 순환형 감압 건조 장치를 제작하여 이를 통해 건조한 김치의 품질 변화를 연구하였다. 종래 건조 기술인 열풍 건조 방법은 60oC 이상의 열풍에 노출시키는 방법으로 40oC 이상의 높은 온도로 높아지면 식품에 함유되어 있는 성분들이 파괴되거나 변형되어 품질이 저하되고, 외형사의 변형을 일으켜 소비자들에게 거부감을 가질 수 있다. 동결 건조 방법은 -50oC 이하의 온도와 진공 상태에서 건조하는 방법으로 열풍 건조의 문제점인 식품의 변형 및 영양소의 파괴를 막을 수 있지만, 24시간 이상의 건조 시간 및 높은 비용으로 생산 효율이 나쁘다는 문제가 있다. 이러한 문제점을 해결하기 위하여 순환형 감압 건조 장치를 제작하여 본 연구에 적용하였다. 건조 시간 별 함수율에서는 순환형 감압 건조의 건조 속도가 10시간으로 가장 짧았으며, 함수율도 시간 별로 일정하게 감소하여 가장 효율적인 건조방법으로 나타났다. drying rate 또한 순환형 감압 건조의 변화 폭이 가장 짧고 안정적으로 감소하는 것으로 나타났다. 이에 따른 건조 수율 또한 가장 높게 나타났다. pH, 적정산도 및 염도 측정은 순환형 감압 건조 김치가 일반 건조 전 김치와 비교하여 비슷한 수치를 보여 특성 변화 없이 안정적으로 건조가 되었다. 건조 김치의색도는 순환형 감압 건조 김치의 적색도가 일반 건조 전김치와 가장 비슷한 수치를 나타내어 pH, 적정산도 및 염도의 결과와 함께 가장 안정적으로 건조된 것을 알 수 있었다. 또한 향기 성분의 분석에서도 건조 전 김치의 황화물과 ethanol 및 acetic acid 등의 성분함량과 비슷한 수치를 나타내어 순환형 감압 건조 과정에 있어 김치의 풍미를 유지하였다. 관능 평가의 경우 색과 Texture에서 감압 건조김치가 가장 우수한 것으로 나타났다. 따라서 순환형 감압건조 방법을 이용하여 김치 등의 식품을 건조하는 것이 가장 안정적이고 우수한 건조 방법으로 나타났다. 이러한 건조 김치의 품질 평가를 통하여 순환형 감압 건조 김치가 가장 안정적이고 효율적인 건조 방법이라는 것을 알 수 있었으며 이러한 건조 방법을 이용하여 김치를 상품화 한다면 기능성 식품으로 다양한 식품으로 활용하는데 가능성이 큰 것으로 기대된다.

저탄소 공정을 이용한 추출 기술인 초음파, 마이크로파 및 초고압 추출 공정기술의 이산화탄소 배출량(TCO2)과 얻어진 저분자 진세노사이드 총량의 상관관계를 비교하였다. 기존의 공정인 열수 추출 공정의 TCO2 배출량은 약 0.4 TCO2로 나타났다. 마이크로파 추출 공정의 경우 0.1437 Ton 당 CO2를 배출하는 것으로 확인 되었다. 또한, 초음파 추출 공정의 경우 0.0862 Ton 당 CO2를 배출하는 것을 확인 하였으며, 초고압 추출 공정의 경우 0.1014 Ton당 CO2를 배출하는 것을 확인 하였다. 저탄소 공정별 저분자 진세노사이드의 전환된 양을 측정한 결과 마이크로파 추출 공정의 경우 약 246.65% 정도 증진된 것을 확인 할 수 있었다. 또한, 초음파 공정의 약 275.71% 증진된 결과를 보였다. 초고압 추출 공정의 경우에는 약 295.21% 증진된 결과를 얻었다. 전체적으로 열수 추출 공정의 경우 얻어진 저분자 진세노사이드가 적은 반면 CO2 배출량이 매우 높은 것을 확인하였다. 반대로, 저탄소 추출 공정인 마이크로파, 초음파 및 초고압 공정의 경우 얻어진 저분자 진세노사이드의 양이 높으며, 방출되는 CO2의 양이 기존의 재래 방법보다 적은 것을 확인 하였다. 따라서, 저탄소 추출 공정인 마이크로파, 초음파, 초고압 추출 공정을 통해 인삼을 효과적으로 추출을 할 수 있으며, 친환경 저탄소 공법을 통해 CO2 발생량을 억제하여 경제적으로 천연물을 추출할 수 있을 것으로 사료된다.

Fresh oyster mushrooms (Pleurotus ostreatus) were gamma-irradiated at 0, 1, 2, and 3 kGy. The effects on various quality attributes were determined during storage at . Color changes were more prominent in the cap region than the stem part. At the start of storage increase of Hunter's L-value (lightness) was observed in the caps of 2 and 3 kGy-irradiated samples. The L-value was higher in the all irradiated samples during storage. The trend was different in the case of stem region, where L-value decreased upon irradiation, but remained high throughout storage. The -value declined, whereas the b-value increased following irradiation. Irradiation showed a dose-dependent effect on the firmness, which was clearer during storage, but the samples irradiated at 1 kGy maintained an overall better texture than other irradiated samples. The weight loss was also higher in the all irradiated samples during storage. The samples irradiated at 1 kGy showed good physical appearance without any fungal attack at the end of storage; however color change in cap region was quite apparent. The ultra-structural drastic effect of irradiation was understandable using scanning electron microscopy. E-nose analysis demonstrated a clear change in the volatile profiles of all irradiated samples. Although the effect of irradiation on quality characteristics was quite clear but the all irradiated samples were free from fungal attack that was observed in the case of control sample.

일미찰과 흑진주찰의 예냉온도와 저온처리를 통한 풋옥수수의 품질 변이를 연구한 결과는 다음과 같다. 1. 예냉 처리 및 저장에 따른 품질변화에서 품종간 차이는 미비하였으며, 예냉처리 보다 저온저장이 외관 품질변화에는 더 큰 영향을 미침을 알 수 있었다. 2. 예냉처리 후 저장고 입고 초기까지의 이삭 품온 변화는 예냉처리구는 4시간, 냉장처리구는 입고 후 약 10시간 후 품온과 외기가 같아졌으며 저온처리구에서는 10일 까지도 포엽의 외관상 신선도가 유지되었다. 3. 상온처리구에서는 포엽이 마르면서 신선도도 떨어지고 중량도 감소하지만 고습으로 유지되는 저온처리구에서는 중량감소가 거의 일어나지 않았다. 4. 저장에 따른 식미관능평가에서 상온처리구에서는 저장기간이 길어질수록 식감이 떨어지지만 저온처리구는 오히려 수확직후의 옥수수보다 식감이 좋게 느껴질 정도로 부드럽고 씹는 맛이 좋았다.

느타리버섯의 생육단계에서 재배온도 및 상대습도를 조절하여 선도 유지 기간을 연장하기 위해 수행한 결과, 생육온도별 저장기간에 따른 버섯의 수분함량은 상대습도가 낮은 처리에서 다소 낮았다. 생육조건별 중량감모율은 저장기간이 길수록 증가하였으며, 처리간 큰 차이 없었고, 갓신장율은 저온생육시에는 상대습도 95±5% 처리에서 저장 21일에 가장 높았으며, 대조구에서는 상대습도 80±5% 처리에서는 저장 24일에 가장 높았다. 버섯의 물성을 분석한 결과, 경도와 탄성은 저장기간이 길수록 낮아지는 경향이었으며, 상대습도 및 생육온도에 의한 차이는 거의 없었다. 따라서, 느타리버섯을 발이유기 후 생육온도 13℃, 상대습도 80%이상으로 조절하여 생육하여 250~300g 랩포장하여 4±1℃에 저장 했을때 24일까지 신선도를 유지할 수 있었다.

This study was carried to investigate the suitable conditions of Pleurotus eryngii through precooling for the more long-term freshness. The time to be same temperatures between P. eryngii and storage room through precooling at 0℃ and 4℃ were showed 2 hours and 5.5 hours, respectively. P. eryngii was cooled within 6 hours and 18 hours at 0℃ and 4℃ with two type, forced air cooling and pressure cooling. After precooling, P. eryngii was packed 400±10g with anti-fog film, and then stored at 4±1℃. In all treatment of precooling, the weight loss was peaked at 25 days and hardness of P. eryngii were decreased at 10 days during storage. There were no significant freshness differences between precooling type and conditions. It was found that the optimum stored period of P. eryngii at 4℃ after precooling was estimated to be 30~35days. Consequently, it is necessary to elucidate efficient and economic precooling conditions.
