  • 본 실험은 $\beta$-cyclodextrin을 사용하여 cholesterol을 제거한 균질우유로부터 cholesterol이 제거된 치즈 제조의 조건을 규명하고, 그 조건에 따라 제조된 cheese의 특성 및 관능 검사를 함으로써 cholesterol이 제거된 cheese의 개발 가능성을 조사하는데 그 목적을 두고 있다. 치즈 제조에 적합하다고 사료되는 낮은 균질압력에서 효과적인 cholesterol 제거율을 알아보기 위해 균질압력 0, 250, 500, 750, 1000psi(0-70kg/$cm^2$와 균질온도 40, 50, 60, $70^{\circ}$ 그리고 $\beta$-cyclodextrin 첨가량 1.0, 1.5 2.0% 등의 3가지 조건에 따라 우유를 처리하여 cholesterol이 제거된 cheese의 제조에 적합한 조건으로는 균질압력 1000psi(70kg/$cm^2$), 균질 온도 $70^{\circ}$$0^{\circ}C$, $\beta$-cyclodextrin 첨가량 2.0%로 관찰되었다. 따라서 균질온도는 $70^{\circ}$로 정하고, 균질압력을 400, 600, 900, 1200si(0,- 91kg/$cm^2$)로, $\beta$-cyclodextrin 첨가량을 1과 2%로 처리하여 제조한 cheese와 균질을 하지 않고 $\beta$-cyclodextrin의 처리를 하지 알은 control 치즈간의 수율, cholesterol 제거율, mettability, stretchability, oiling off, 조직검사, 관능검사 등의 실험을 실시하여 control 치즈와 가장 유사한 cholesterol이 제거된 cheese 개발의 가능성을 시도하였고, 그 결과는 다음과 같다. 1. Cholesterol을 제거한 cheese의 제조에서 최적조건은 균질압력 1200psi(70kg$cm^2$), 균질온도 $70^{\circ}$, $\beta$-cyclodextrin 첨가량 2%였으며, 이때 우유의 cholesterol의 제거율이 86.05%로 가장 높게 나타났다. 2. Cholesterol을 제거한 cheese들의 수율은 모두 12.53%(control 10.54%) 이상으로 균질 처리가 cheese의 수율을 18.88%이상 향상시키는 것으로 나타났다. 3. 유지방 함량 23.80%인 control 치즈의 cholesterol 함량은 81.47mg/100g이었고, 균질압력 1200psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 2%를 첨가한 cheese에서는 cholesterol 함량이 20.15mg/100g으로 cholesterol 제거율이 75.27%로 가장 높게 나타났다. 4. Meltability는 균질압력 1200psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 1과 2%로 처리한 치즈에서 2.25cm(control 3.34cm)로 가장 낮았으며, 균질압력이 증가할수록 meltability가 감소하여 치즈의 품질을 저하시켰다. 5. Control 치즈의 stretchability는 30cm 이상 늘어나 가장 양호한 수치인 5점을 나타낸 반면, cholesterol을 제거한 cheese에서는 5~10cm 사이를 나타내어 2점으로 stretchability가 저하된 것을 볼 수 있었다. 6. Oiling off는 균질압력 1200psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 1과 2%로 처리한 치즈에서 0.03%(control 2.46%)로 가장 낮았으며, 균질압력이 증가할수록 oiling off는 감소하여 치즈의 외관상 품질을 향상시켰다. 7. Hardness, gumminess, chewiness는 균질압력 1200psi(91kg/$\textrm{cm}^2$)에 $\beta$-cyclodextrin 1%로 처리한 치즈에서 각각 나타내었으며, control과 cholesterol을 제거한 치즈들 사이에 유의적 (p<0.05) 차이를 보이며 큰 감소를 나타내었다. 8. Cholesterol을 제거한 cheese의 appearance와 flavor는 1200psi (91kg/$cm^2$)일 때 각각 가장 높은 5,56과 4.63(control 4.00)으로 균질압력이 증가하면서 향상되었으며, texture score는 균질압력 1200psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 2%일때 1.22(control 4.00)로 가장 낮은 수치를 나타내었고, 균질이 cheese의 texture score를 상당히 저하시키는 것을 알 수 있었다. 9. 이 실험결과, 균질압력 1200psi(91kg/$cm^2$)에 $\beta$-cyclodextrin 2% 첨가한 cheese에서 cholesterol 제거율이 75.27%로 가장 높았으며, 균질처리가 cheese의 수율, oiling off, appearance score, flavor scope 등을 향상시켰고, meltability, stretchability, hardness, gumminess, chewiness, texture score를 저하시키는 것으로 나타나 cholesterol이 상당부분 제거된 cheese의 개발 가능성이 관찰되었다.

  • This study was carried out to evaluate the effects of various kinds of salt on the quality and storage characteristics of tteokgalbi. The tteokgalbi was prepared using four types of salt: 1.5% purified salt (control, C), 1.5% five-year-old solar salt (FS), 1.5% Topan solar salt (TS), and 1.5% French Gu$\acute{e}$rande solar salt (GS). The moisture, crude lipid, crude ash, crude protein and calorie contents, water holding capacity, and cooking loss were not significantly different between control and all other treatments. As for the textural characteristics, the use of GS increased the hardness of the tteokgalbi. According to the sensory evaluation, the use of TS had the best score in springiness. Tteokgalbi made with TS and GS had the two highest scores in flavor and total acceptability. During 15 d of storage, the contents of 2-thiobarbituric acid (TBA) value, volatile basic nitrogen (VBN) and the total microbial counts increased, while the pH decreased. The TBA values of the tteokgalbi containing TS and GS were lower than that of C. Lightness (L) and yellowness (b) values decreased during storage, but redness (a) displayed no significant difference during storage. Overall, the best results, in terms of TBA value and sensory attributes, were obtained for the tteokgalbi containing TS and GS.

  • We researched the physical, chemical, functional, textural, and manufacturing characteristics of yellow layer cake which prepared by adding different amounts of persimmon leaf powder (0, 4, 8, 12, 16%). The color of the crumbs inside the cake appeared dark, demonstrating that the L value decreased as the amount of persimmon leaf powder increased. The value of a, which corresponds to the level of redness, increased and the cake appeared dark red as the amount of persimmon leaf powder added increased; whereas, the yellowness of the cake tended to decrease as the value of b, which corresponds to the level of yellowness, gradually. As the amount of persimmon leaf powder added increased, the specific loaf volume of the cake increased, but the amount of baking loss tended to be similar at all. The textural characteristics of hardness and gumminess tended to increase, but cohesion and elasticity were not influenced by the addition of persimmon leaf powder. In the sensory test, color was rated low, but flavor, taste, and texture showed the highest score in 8% as the amount of persimmon leaf powder added increased. The general preference was highest when the persimmon leaf powder was added in the amount of 8%, and it decreased as the amount of persimmon leaf powder added increased.

  • The effect of medicinal herb powder addition on the physicochemical characteristics of silk-tofu was investigated. Moisture content of silk-tofu decreased during the storage. The pH value of silk-tofu decreased a little until 2 days' storage, and then increased rapidly. The chromaticity of L value decreased for all silk-tofu during the storage. The a value increased a little at initial storage, and then tended to decrease, while b values increased significantly during storage. The contents of free amino acid were 4 times higher in silk-tofu than those in market tofu. Hardness, gumminess and chewiness of all silk-tofu increased rapidly during storage. Cohesiveness values decreased a little at initial storage, and then kept to increase upon storage. Generally, the total plate counts of bacteria of all silk-tofu increased during storage, and those of silk tofu with added medicinal herb powder were shown to be significantly lower than those in control. In sensory evaluation, color, structure, softness and overall acceptability of silk tofu with added dangui powder(dang-T) and control(con-T) were about to be high, and nutty taste and flavor of control silk-tofu was the highest in score.

  • The gamma irradiation effect of dried fernbraken was investigated on the physical and sensory qualities during and after soaking process. Dried fernbraken packaged in vacuum was irradiated up to 7 kGy with v-ray produced by 132 Cs at 0℃. Moisture content and rehydration rate of gamma-irradiated fernbraken after soaking increased significantly depending on the irradiation doses(p<0.05). Lightness(L), redness(a) and yellowness(b) values of Hunter color system increased significantly in the gamma-irradiated fernbraken after soaking, compared with control, while the hardness and chewiness by the texture analyser decreased significantly in irradiated ones. Sensory evaluation results showed that the mean scores of flavor, appearance, taste, texture and over-all acceptability in soaked fernbraken irradiated were not significantly different from those in control, except higher preference score of texture in irradiated ones. From these results, it might be concluded that the irradiation does not affect the physical and sensory qualities of dried fernbraken during and after soaking, especially in texture.

  • The effects of four different oligosaccharides with 2, 4, 6% (w/w) (fructo-oligosaccharide, xylo-oligosaccharide, chito-oligosaccharide and soybean-oligosaccharide) on gelatinization and retrogradation of sulgidduks (Korean rice cake) were examined. The amylograph results of rice flour showed that chito-oligosaccharide hastened gelatinization, and delayed retrogradation. Blue value results of chito-oligosaccharide added sulgidduks showed retarded retrogradation during storage (1, 2 and 3 days). Chitooligosaccharide and xylo-oligosaccharide added sulgidduks showed significantly lower hardness during storage. Lightness (L) decreased and redness (a) and yellowness (b) increased with increasing oligosaccharide amounts. In the sensory evaluation of sulgidduks, color of fructo-oligosaccharide added sulgidduks obtained the highest score among oligosaccharide added sulgidduks. During storage, xylo-oligosaccharide and fructo-oligosaccharide added sulgidduks had higher flavor, taste, graininess and overall quality scores than the control. Physicochemical tests showed that chito-oligosaccharide retarded retrogradation, whereas chitooligosaccharide- added sulgidduks had low scores in sensory tests due to aftertaste of chito-oligosaccharide. To improve the sensory quality of chito-oligosaccharide added sulgidduks, mixtures of chito-oligosaccharide with xylo-oligosaccharide and fructooligosaccharide were applied at ratios of 3%:3%, 2%:4% and 1%:5%, respectively. The addition of chito-oligosaccharide and xylo-oligosaccharide at ratios of 2%:4% and 1%:5% to sulgidduks showed relatively high scores in the sensory evaluation retarding retrogradation.

  • This study investigated the quality characteristics of makpyeon made of dry milled rice powder according to soaking time. Makpyeon samples made of dry milled rice powder were analyzied with various soacking time, the moisture content, pH, Hunter's color value texture characteristics, attribute difference test and acceptance test. The moisture content of makpyeon did not indicate difference among samples. pH resulted in MS90 showed the lowest moisture content. The L-value (lightness) and a-value (greenness) result in that MS0 showed the highest and decreased according to soaking time. The b-value (yellowness) increased according to soaking time, MS90 showed the highest. TPA resulted in that MS90 indicated the highest hardness, chewiness, gumminess and the lowest adhesiveness. Hardness of makpyeon samples was higher than sulgitteok samples, adhesiveness was lower than those of sulgitteok in each soaking time. Based on attribute difference test, the score of brightness, moistness, glossy, particle size were decreased and firmness were increased according to soaking times. Flavor, taste and mouth feel attribute was stronger in makpyeon samples with the longer soaking time. Acceptance results showed that MS0 and MS30 (soaking for 30 min) were preferred the most. Also limitations and future research directions of this study were discussed.
