This study was performed to evaluate the effect of lemon and cranberry juice on meat quality of chicken thighs during cold storage. Experimental groups were chicken thigh meat dipped into distilled water (CON), 1% lemon juice (LJ), 1% cranberry juice (CJ), and a mixture of 0.5% lemon juice and 0.5% cranberry juice (LCJ). The meat quality traits were determined at day 0, 3, 6, and 9 during cold storage at $4^{\circ}C$. The pH value of all treatments was lower than that of the control (P<0.05). Total microorganisms of CJ and LCJ at day 9 was 6.94 and 6.76 log CFU/g, respectively, whereas that of the control was 7.51 log CFU/g. The $a^*$ value of CJ and LCJ was higher than that of CON and LJ during storage (P<0.05), whereas the $b^*$ value of LJ, CL, and LCJ was lower than that of CON at day 6 and 9 (P<0.05). Overall acceptability of all treatments was significantly higher than that of CON after day 3. Thiobarbituric acid reactive substances and volatile basic nitrogen values were lower than those of the CON after day 3 (P<0.05). Principle component analysis (PCA) of the aroma pattern of all treatments was closer together, whereas PCA of the CON was scattered with the increase in storage days. This result suggests that dipping the chicken thigh meat into the lemon and cranberry juice could be beneficial to enhance chicken thigh meat quality by retardation of total microbes, lipid oxidation, and protein decomposition.

레몬은 쌍떡잎식물 쥐손이풀목 운향과로 인도 북동부가 원산지이며 비타민 C가 풍부하다. 주로 음료수의 향미료나 레몬필로 사용되고 있으며 구연산이 함유되어 있어 신맛이 강하다. 이에 본 연구에서는 비타민 C의 좋은 급원인 레몬에 설탕, 꿀과 고구마전분, 감자전분, 옥수수전분, 한천, 젤라틴의 겔화제를 사용한 과편을 개발하여 pH, 색도, 관능검사와 기계적 물성검사를 실시하였다. 레몬과편의 제조는 예비실험을 통하여 조리법을 개발하였으며 레몬즙 21.4％, 겔화제 6.7％, 물 53.3％, 설탕 13.5％, 꿀 5.3％를 첨가하였다.

홍삼분말을 사용하여 홍삼의 독특한 풍미와 약리적 기능을 접목시켜 기호성을 높이고 기능성을 부여한 제품을 개발하기 위하여 레몬즙 21.4％, 고구마전분 6.7％, 물 53.3％, 설탕 13.3％, 꿀 5.3％를 첨가하여 제조한 레몬과편에 홍삼을 각각 0, 2, 4, 6, 8, 10％첨가하여 제조하였다. 레몬홍삼과편은 pH, 색도, 관능검사와 기계적 물성검사를 실시하였다. 그 결과 pH는 2.95-3.00정도로 홍삼 첨가량에 영향이 없었으며 관능검사 항목 중 표면색은 홍삼의 함량이 증가할수록 진했다. (중략)

The modeling analysis for objects placed in a given space can be described objectively when their visual image structure is grasped. It can't be answered without first analyzing the basic program, visual expression. And when the whole aspect of the visual image of the desired interior utensils is presented, the mindset of its designer can be deduced from that. Therefore, the study was based on the lemon juice squeezer, one of the interior kitchen utensils that Philippe Starck designed for Italy ALESSI company. For the study method, putting'The Elements of Dynamic Symmetry' by Prof. Jay Hambidge into practice, 'paradigm' analysis containing the whole'lemon juice squeezer'image was attempted. And to describe it, the visual mark description method by Prof. Bok-Young Kim was used. In conclusion, henceforth, the relationship between interior space and articles, the relationship between object and user, the modeling critique or analysis of the production itself shoud not be intended to be emotional. On the contrary, the study presented an art analyic methodology that can analyze and describe the visual image structure numerically, and confirm the relationship between form and content.

This research was to evaluate conservational stability of cleaning treatment and color recovery by weak acid treatment on ivory. Before this experiment, had an ivory identification such as black light and schreger angle to find whether it is authentic or not. In wet cleaning treatment on ivory, used polar solvents such as distilled water, acetone, ethyl alcohol and acetic acid which usually used for cleaning ivory and bones. After cleaning took a experiment to evaluate conservational stability in surface observation, calculate weight and color difference. Following these results, these polar solvents were stable on the ivory samples. On the other hand, in weak acid treatment, used samples that were exposed by UV-A, UV-B, UV-C for 1 weeks, to restore its color from changed to original color. After treatment, found tiny cracks and exfoliation on the surface. Moreover, the color changed when it is treated by lemon juice, so, it is impossible to adapt.

The purpose of this study was to investigate the differences in vitamin C and mineral contents in perilla leaves as a result of different cooking methods. The results are summarized as follows. In cutting up the perilla leaves, the vitamin C content decreased by 40% with no significant difference made to the mineral content. Steaming was more effective in retaining vitamin C compared to blanching. With increasing treatment times. decreasing amounts of vitamin C remained. There was no significant change in mineral contents except for potassium. In the case of treating with vinegar or lemon juice, more vitamin C remained than when not treated, and there was little influence on the mineral contents. In the solubilization effect of calcium seasoned with acid, rice vinegar was most effective followed by lemon juice, apple juice, brown rice vinegar, then persimmon vinegar. There was a little or almost no vitamin C remaining in kkaennip kimchi. In terms of storing time, raw seasoned kkaennip kimchi had higher mineral contents than blanched or steamed kkaennip kimchis.

In order to increase the antioxidant effect and preference of jujube-omija herbal sauce, we added ethanol extracts of 12 kinds of food and 12 kinds of medicinal herb to the sauce, and then evaluated the antioxidant activity and sensory characteristics. The antioxidant activity of the jujube-omija herbal sauces was greatly increased by the addition of ethanol extracts of foods such as green tea, mugwort, mint, lemon, leek, etc. and those of medicinal herbs such as ginseng. pine needle, the root of arrowroot, orange peel, etc.. Due to the high content of phenolic compounds, the ethanol extracts foods and medicinal herbs appeared to be responsible for high electron-donating ability and low hydroperoxide productivity. While the jujube-omija sauce with the extracts of green tea, mugwort, ginseng and pine needle were not preferred by the panels due to bitter taste and aroma, those of lemon, fruit of Chinese quince, orange peel, etc. were preferred with their sweet and a little sour taste and showed a high antioxidant activity. Especially, lemon juice was the best to increase the antioxidant activity and the preference of the jujube-omija herbal sauce.

The purpose of this study was to investigate me effects of garlic or lemon juice on quality characteristics of fish muscle. The samples treated with garlic or lemon juice by me amount of 5% or 10% (w/w) of fish muscIe were stored at $4{\pm}1^{\circ}C$ and $-18{\pm}2^{\circ}C$ for 10 and 40 days, respectively. The results are summarized as follows; 1. In me taste of samples, me samples treated with 5% garlic juice showed me most favorite tendency all me storage time at $4{\pm}1^{\circ}C$ and $-18{\pm}2^{\circ}C$. 2. There were significant in fishy odor after 5 days of storage at $4{\pm}1^{\circ}C$ and 40 days of storage at $-18{\pm}2^{\circ}C$ . The fishy odor of samples treated with garlic juice were weaker man those of samples untreated or treated with lemon juice. 3. The appearance was evaluated the worst in 10% lemon juice treated sample among all me samples. 4. The hardness of the samples treated with lemon juice were lower man those of samples untreated or treated with garlic juice during all the storage time at $4{\pm}1^{\circ}C$ and $-18{\pm}2^{\circ}C$. 5. The score of overall quality was the highest in sample treated with 5% garlic juice during all the storage time at $-18{\pm}2^{\circ}C$.
