S-allyl-L- cysteine(SAC)의 함량은 EB, CB 및 WB군의 순으 로 높았으며, 발효 25일 후에 7.00~19.64mg/100mL였으나 발효 초기에 비해 유의적인 차이는 없었다. 유기산은 총 6종이 검출되었으며 검출된 유기산 중 acetic acid(5341.17~5857.60mg/100mL)의 함량이 가장 높았고 EB군의 경우 citric acid의 함량은 다른 실험군에 비해 63% 정도로 낮은 함량이었으나 propionic acid는 약 1.8배 이상 높은 함량으로 흑마늘의 첨가 형태에 따른 차이가 컸다. 흑마늘 식초 의 무기물 중 칼륨의 함량이 월등히 높았고, 다음으로 인, 마그네슘의 순이었고, 이들을 제외한 무기물 함량은 100mg/L 미만이었다.

본 연구는 시중에 유통 중인 식육제품 중에서 유통기한이 임박한 다양한 육가공제품을 구입하여 미생 물 및 위생적 품질을 비교 분석하였다. 총 20점(햄6점, 베이컨 3점, 소시지 11점) 시료에 대해 pH, 수 분활성도(Aw), 지방산패도(TBARS), 단백질변패도(VBN), 총세균수(total aerobic counts), meat color 등의 분석을 실시하였다. 분석결과 pH는 최저 5.33에서 최대 6.59 범위를 나타내었고, Aw의 경우 0.90~0.93 범위를 보였다. TBARS는 0.11~0.59, VBN의 경우 2.37~14.75 수치를 나타내었다. 총세균 수는 최대 2.80CFU/g 이하로 검출되어 매우 낮은 수준을 보였다. 육색의 측정 결과, 명도(L*)는 56-72, 적색도(a*)는 5.2-34, 황색도(b*)는 0.7-16범위를 나타내었다. 본 연구 결과 제조공정과 첨가 물 차이에 따른 식육제품의 품질 특성에 차이들은 있었지만, 유통기한 내에 있는 제품의 품질 저하는 관찰되지 않았다. 따라서 시중에 유통 중인 육가공제품의 위생적, 미생물학적 안전성 평가의 결과로부 터 유통기한이 매우 잘 적용되고 있는 것으로 평가되었다.

The quality of customer service has been one of the most representative determinants of retailers’ sustainable competitiveness. Since Parasuraman et al. (1988) introduced the service quality instrument, called SERVQUAL, many studies have used SERVQUAL to measure service quality in various domains. However, since SERVQUAL was originally developed to measure general service quality, it didn’t fully consider the underlying characteristics of a specific industry such as retailing. Recently, as retail industry is becoming more competitive, there is a general agreement that the most important retailing strategy for creating competitive advantage is the delivery of high service quality. From the retail manager’s perspective, the level of service quality is highly correlated with the level of customer loyalty and the customer’s favorable word-of-mouth behavior. In this sense, most retail managers would be very interested in the question of how to increase their customer loyalty rate and, therefore, to elaborate this question in more detail, service quality study in a retail setting would be very important. Current measures of service quality, including SERVQUAL, do not adequately capture customers’ perceptions of service quality for retail stores such as department stores or general discount stores. The main objective of this study is to investigate the usefulness and applicability of the different methods, including SERVQUAL, in measuring the service quality of retail environment and their relationships to customer loyalty and word-of-mouth behavior. By exploring the suitability of each different measurement method for retail service quality, this study enhances the understanding of the major dimensions of retail service quality and the analysis of the effect of service quality on customer loyalty and word-of-mouth behavior.

The present study investigated the effects of processing parameters such as time (10, 20, 30, 40 min), pressure (25, 50, 75, 100 MPa), and the salinity of brine (0~10%(w/v)) on jacopever (Sebastes schlegeli Hilgendorf) in order to establish optimization of the three factors using a high hydrostatic pressure (HHP) machine. To do so, it analyzed the quality characteristics of volatile basic nitrogen (VBN), trimethylamine (TMA), total bacterial counts, dynamic viscoelasticities, and differential scanning calorimetry (DSC) properties. First, when the time increased to 40 mins, by 10 min intervals, the total bacterial counts in HHP groups under 25℃, 100 MPa, and 4%(w/v) brine were significantly decreased except for the first 10 min in comparison to the control group. In regards to DSC properties, the onset temperature (TO) of the first endothermal curve was significantly reduced. Second, when the pressure level increased up to 100 MPa by 25 MPa increments, the total bacterial counts in the HHP samples significantly decreased for 20 min at 50 MPa or higher. As the pressure increased, G′, G″ and the slope of tan δ decreased (except for 50 MPa). Third, in regards to the salinities of brine, when the HHP processing was treated at 100 MPa, 25℃ for 20 min, the total bacterial counts of all the HHP groups significantly decreased in comparison to those of the control group. A significant difference was found in the enthalpy of the second endothermic curve in the 6~10%(w/v) (except 7%(w/v)) HHP groups. Therefore, the salinity of the immersion water under the HHP condition was appropriate when it was lower than 6%(w/v). The present study demonstrated that the optimum parameter condition according to/under the condition of the microbial inhibition and economic effects using an HHP would be the reaction time for 20 min, reaction pressure at 100 MPa, and the salinity of 4%(w/v) brine.

The purpose of this study was to investigate the effects of Capsosiphon fulvescens powder on the functional and sensory characteristics of dumpling shell. Various dumpling shell samples were prepared with wheat flour along with the addition of different amounts of Capsosiphon fulvescens powder, and then instrumental characteristics and sensory evaluations were investigated. According to amylograph data, the composite Capsosiphon fulvescens powder-wheat flour samples had increased gelatinization temperatures with increasing Capsosiphon fulvescens powder content; whereas initial viscosity at 95oC, viscosity at 95oC after 15minutes, and maximum viscosity were reduced. In terms of Hunter's color values, L, a and b values decreased with increasing Capsosiphon fulvescens powder content. Besides cooked weight, cooked volume and turbidity of dumpling shell increased as the addition level of Capsosiphon fulvescens powder increase. In terms of textural characteristics, addition of Capsosiphon fulvescens powder increased springiness, chewiness, brittleness, pringiness and adhesiveness. Based on sensory evaluations, the overall preference of dumpling shell with 3% added Capsosiphon fulvescens powder, was more effective than control.

This study was carried out to evaluate the basic characteristics of red wine processed from ‘Cheongsan (Vitis amurensis)’ grape cultivar. In order to compare the quality of ‘Cheongsan’ red wine, ‘Campbell Early’ and ‘Muscat Bailey A, MBA’ red wines were also utilized for this study. The pH of the red wines produced from ‘Cheongsan’, ‘Campbell Early’ and ‘MBA’ were 3.1, 3.6 and 4.0, respectively. Tannin, polyphenol, and anthocyanin contents of the ‘Cheongsan’ red wine were 2,939 mg/L, 1,516.2 mg/ L, and 1,882.4 mg/L, respectively. These values were about twice those of ‘Campbell Early’ and ‘MBA’ red wines. The antioxidant level of ‘Cheongsan’ red wine was found to be 5,413.9 mg/L, which was also two times higher than 'Campbell Early' and 'MBA' red wines. Although the acidity of ‘Cheongsan’ red wine is relatively high, ‘Cheongsan’ red wine contains a lot of tannin, matures over an extended period of time and has excellent antioxidant properties. These results indicated that 'Chengsan' grape could be an excellent source for production of high quality red wine.

The purpose of this study was to investigate the quality characteristics of makpyeon prepared with dry milled rice powder. The makpyeon samples prepared with dry milled rice powder and various amount makgeolli (0% (CON), 25% (M25), 50% (M50), 75% (M75), 100% (M100)), and analyzed for moisture content, pH, Hunter’s color value, TPA and sensory evaluation. The moisture content did not showed significant difference among makpyeon samples. The L-value, a-value resulted in that CON showed the highest and decreased with the amount of makgeolli. The b-value of makpyeon samples showed that CON was the lowest and increased with the amount of makgeolli. TPA resulted in that M100 showed the highest hardness and the lowest adhesiveness, cohesiveness. Chewiness and gumminess of makpyeon samples were higher than those of CON. Based on quantitative descriptive analysis, the score of brightness, moistness, particle size and gloss of showed higher in CON that in makpyeon samples, firmness increased with the amount of makgeolli. Flavor attributes of liquor odor, sour odor, fermentation odor of makpyeon was stronger in makpyeon samples that in CON with the amount of makgeolli. Acceptance test resulted in makpyeon made with CON, 100% of makgeolli (M100) showed the significantly highest score in taste and overall acceptance.

In this study Muffins adding each 0, 1, 3, 5 7% of Acai Berry powder, which has very high anti-oxidant constituent, have been made, and its quality characteristics have been surveyed. From the volume and specific volume measurement, it has been decreased for MA1, 1% of Acai Berry powder added muffin, but the tendency thereafter has shown increasing (p<0.001). From texture characteristics gumminess and chewiness of MA0, reference group, was the highest by 885.86 g/ cm and 6645.71 g, and has shown decreasing tendency as per the adding rate of Acai Berry powder increased (0.001). The electronics scavenging activity of MA7, 7% added muffin, was the highest by 68.91%, and the ascending order was MA1 < Reference Group < MA3 < MA5 < MA7. From the preference test of Acai Berry powder added muffin, MA3, 3% added muffin, was the most preferable one from color, taste as well as total preference. As the added volume of Acai Berry powder is 5% or more, the typical taste and flavor of Acai Berry gives influence to the taste and flavor of muffin, so the preference level has been decreased. Thus the added volume of Acai Berry powder 5% or more is not recommendable.

This study investigated properties of bread utilizing extracts of ginseng powder. Ginseng powder bread was baked. Addition of 1~3% of ginseng powder extract to wheat flour was carried out. Rheological properties, dough pH, dough volume, bread volume, water absorption capacity, baking loss, bread color, bread texture, and sensory evaluation were tested to examine properties of bread baked with extracts of ginseng powder. The results are as follows. The dough pH decreased gradually with increasing ginseng powder extract concentration. The bread volume, baking loss, and bread weight increased with increasing use of ginseng powder extract, and springiness and cohesiveness increased as red ginseng powder additive concentration increased. Lightness of the L decreased while a and b increased. In the sensory evaluation, ginseng powder with 1% ginseng powder extract was evaluated as the best for taste, texture, flavor, and overall acceptability.

The effect of transplanting and harvesting dates on growth, yield, and quality of sweetpotato varieties was studied. Three sweetpotato varieties, Yulmi, Singeonmi, and Dahomi, were transplanted on 23 Apr., 21 May, 5 June, 15 June, 25 June, 5 July, 15 July, and 25 July. Fresh vine weight and marketable storage root yield of the three varieties were the highest in transplanting plots on 23 April and 21 May, respectively, and those tended to decrease when transplanting dates were late after May. GDD (Growing Degree Days) and cumulative radiation seemed to be related to marketable storage root yield. Number of marketable storage root per plant, average weight of marketable storage root, and marketable storage root yield were significantly different according to transplanting dates. Marketable storage root yield showed significantly positive correlations with fresh vine weight, number of marketable storage roots, and average weight of marketable storage roots. Hardness and dry matter content of storage root showed significantly positive correlations with starch content and decreased with late transplanting dates in Yulmi and Singeonmi varieties. Pasting temperature showed significantly positive correlations with soluble solid content, dry matter content, and amylose content, but it showed significantly negative correlations with breakdown. Setback was significantly different among varieties, but it was not significantly different in transplanting dates.

Korean organic Hanwoo was compared to imported beefs from the America and Australia on the quality characteristics and antioxidant activities. Crude lipid content was significantly higher in Hanwoo. Marbling of Hanwoo has been recognized as well among the comparison groups. Cooking loss of Hanwoo was significantly lower than imported beefs, and its water holding capacity was significantly higher. After cooking, share force was significantly lower in Hanwoo than imported beefs. Contents of total composition amino acid were lower in Hanwoo than imported beefs, but ratio of essential amino acid was higher in Hanwoo. In Hanwoo, contents of saturated fatty acid(SFA) were lower, and poly unsaturated fatty acid(PUFA) content was significantly higher than imported beefs. Especially, oleic acid content was ranged 53.95~ 56.05% in all tested beef samples, and its content was the highest in Hanwoo. Hanwoo was higher than imported beefs in MUFA/SFA ratio, but it was lower in PUFA/SFA ratio. Lipid peroxide content was significantly lower in Hanwoo than imported beefs during their storage for 21 days at 4°C. Contents of total phenolic and flavonoid were not significantly different among the comparison groups. Activities of DPPH and ABTS radical scavenging in Hanwoo was significantly higher than American beef, but not significantly different from Australian beef. Therefore, the quality and antioxidant activity of Hanwoo beef are thought to be more dependent on the MUFA than phenolic compounds.

Taro is an alkaline food containing a lot of protein, vitamin C, and minerals. Matang is a food prepared by frying a starch-containing material in oil and glazing with honey or starch syrup and it is widely enjoyed as simple snack or dessert in Asian countries including Korea. In this study, to increase the usability of taro having high nutritional values, taro matang was prepared by varying the types of starch while the physical and sensory properties were investigated. The taro matang was prepared by mixing corn starch, sweet potato starch, potato starch, and sticky rice starch with taro. The chromaticity of taro matang samples were measured, and the results showed that the corn starch taro matang was the brightest (L=40.48±1.17) and the potato starch matang was the darkest (L=33.81±1.33). The pH of the taro matang samples were within the range of 6.16-6.26 with no significant difference. The physical properties of the prepared taro matang samples were measured. The hardness and fracturability of the sweet potato starch taro matang were the highest at 3,414.79 and 1,570.03, respectively. The springiness and chewiness of the corn starch taro matang were the highest at 0.95 and 1,773.24, respectively. With regard to sensory properties and preference, the taro matang samples having lower hardness and brighter chromaticity were preferred. The preference for the flavor, crispness, softness, taste, and overall preference of the potato starch taro matang were the highest. Therefore, taro matang prepared as snack or dessert by mixing with potato starch may satisfy consumers’ demand.

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.

본 연구는 월동배추를 주로 이용하는 한국인의 전통적인 김장방법으로 인한 김장철 배추가격 급등락의 문제해결에 기 여하고자 상대적으로 사용도가 낮은 봄배추를 이용한 김치 의 저장기간 연장과 품질유지를 목적으로 수행되었다. 실험 결과, 경도는 수확시기가 가장 늦은 7월초 김치가 6월 중순 김치보다 유의적으로 높았으나(p<0.01) 숙성이 진행됨에 따 라 저장 8주차에는 수확시기에 따른 유의적인 차이를 보이 지 않았다. 김치 숙성과 상관성이 높은 pH와 산도 측정결과 전반적으로 저장 초기에 비해 pH는 감소하였고, 산도는 증 가하는 경향을 나타내었다. 관능평가 결과, 외관은 김치의 제 조시기와 숙성기를 종합하여 6월말 제조 김치의 외관이 가 장 우수하였고(p<0.05), 저장 4주차와 8주차에는 7월초 김치 가 가장 우수한 것으로 평가되었으나 유의적인 차이는 없었 다. 조직감 및 전반적인 기호도 항목에 있어서도 처리구별 유의적인 차이는 보이지 않았다. 따라서 수확시기에 차이를 둔 봄배추로 김치 제조 시 생배추 상태 또는 제조직후의 차이에 비해 절임과 숙성과정, 양념의 첨가 등을 통해 그 유의 적 차이가 감소됨에 따라 수확시기가 봄배추로 제조된 김치 품질에 미치는 영향은 크지 않음을 확인할 수 있었다. 다만, 수확시기가 가장 늦은 배추로 제조된 김치의 경우 생배추 상 태에서 경도가 유의적으로 높았으며 숙성기간 및 저장기간 이 연장되었으므로 이를 수확시기나 작황사정과 연결하여 차 후 심화된 연구가 필요할 것으로 사료된다.
