This study focused on bean-juice treatment method which have dyeing property to indigo, yellow soil, sappan wood, cochineal and also on the possibility of applying to mordanting. This is different from the active mordanting using chemicals. Natural mordants with development of dyeing are not harmful, also are the medicines for disease. Limestone and ash neutralize the acidic soil. bean-juice protein adhere to cellulose surface and change the physical properties of protein so that coloring of dye is better than before and film non-soluble in water is made. Therefore the color made from bean-juice process lasts after washing. This study try to show one of the ways to improve the current method using the heavy metal which can have bad effects for environment and human being. Bean-juice(raw bean, heated bean) treatment method can be the way to fix the natural dyeing problem of bad dyeing. Bean-juice had been treated under various condition with pre-treatment, post-treatment and raw bean, heated bean. Following results are obtained in this study. In the case of Indigo dyeing, pre-treatment of heated bean shows the biggest difference of color. In the case of yellow soil dyeing, pre-treatment of raw bean-juice shows the biggest gap of color. Pre-treatment of heated bean in sappan wood dyeing case and post-treatment of raw bean show bigger color difference than pre-treatment of raw bean. In cochineal dyeing, raw bean pre-treatment shows the biggest color difference.

Omija, the major material of omigalsu, has liver protective and antioxidant effects, while mung bean has detoxification effects. A series of studies were conducted to standardize the traditional recipe for omigalsu to develop traditional functional drinks made from Omija extract and mung bean juice. Study 1 was designed to determine the optimal conditions for Omija extraction and mung bean juice. A higher water temperature and longer immersion time was associated with higher, free sugar and organic acid contents of omija extract; however, sensory evaluation revealed that the optimal extraction conditions for the highest acceptability, proper taste and red tone were $23^{\circ}C$ and 18 hrs of immersion. Conversely, the pH of the mung bean juice produced by varying the immersion time (5 hr, 11 hr, 17 hr) was found to be neutral, containing small levels of organic acid and free sugar, and showing a yellow tone. The results of the sensory evaluation also showed that the optimal conditions for taste, flavor and yellowness of mung bean juice was 5-hour-long immersion. Study 2 was designed to determine the optimum mixing ratio of omigalsu concentrate. Sensory evaluation revealed that the contents of sugar and total free sugar were highest when the mixing ratio among omija extract, mung bean juice and sugar was 1:1:20%, indicating that these conditions produced the most attractive color and highest overall acceptability. Study 3 was designed to determine the optimum dilution magnification for omigalsu. Sensory evaluation during summer revealed that the omigalsu produced by mixing 54 g of omigalsu concentrate into 200 cc water of $4^{\circ}C$ or $80^{\circ}C$ was most preferred, while during winter. Overall, the optimum dilution magnification for omigalsu was 4.7~5.4.

The objective of this study was to evaluate the quality characteristics of mung bean starch jellies prepared with additions of white lotus steam juice at differing levels (0, 2, 4, 6, 8 mL). The proximate composition of the lotus steam juice was $96.37{\pm}0.04\;g/100\;g$ for moisture, $0.75{\pm}0.01\;g/100\;g$ for crude protein, $0.24{\pm}0.01\;g/100\;g$ for crude fat, and $1.90{\pm}0.07\;g/100\;g$ for crude ash. As the level of lotus steam juice increased, the moisture contents and, L, a and b values of the jellies increased (p<0.05). However, the L value of the WSL8 group did not differ significantly. According to the mechanical evaluation results, hardness values of the WSL4 and WSL6 groups were increased (p<0.05), whereas, cohesiveness, gumminess and adhesiveness were not significantly different among the groups. Springiness was higher (p<0.05) in the WSL8 group compared to the other groups, and, chewiness was higher (p<0.05) in the WLS6, and WSL8 groups than in the WSL2 group. According to the sensory evaluations, the mung bean starch jellies prepared with 4~6 mL of lotus steam juice received the highest preference scores and were therefore chosen as optimal products.

The primary objective of this study was to determine the optimal mixing ratio in preparing Omi-Galsu concentrate. By varying the amounts of Omija extract, mung bean juice, and sugar in the concentrate mixture, we found that pH increased with greater amounts of Omija extract and sugar. According to sensory evaluations, sugar and total free sugar contents were highest when the mixing ratio was 1:1:20%(Omija extract, mung bean juice, and sugar respectively). This ratio also presented the most attractive color and highest overall acceptability.

Hydrocolloids have many applications in foods including their use in dysphagia diets. We aimed to evaluate whether hydrocolloids in foods affect the digestibility of starch and protein, and their effects on antioxidant capacity. The thickening hydrocolloids: locust bean gum and carboxymethyl cellulose, and the gel-forming agents: agar agar, konjacglucomannan, and Hot & Soft Plus were blended with corn starch and soy protein, skim milk, or grape juice and were examined for their in vitro-digestability by comparing the reducing sugar and trichloroacetic acid (TCA)-soluble peptide, for antioxidant capacity by total polyphenol contents and the 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity. The hydrocolloids resulted in a decrease in starch digestibility with the gel-forming agents. Hydrocolloids diminished TCA-soluble peptides in skim milk compared to soy protein with the exception of locust bean gum and decreased free radical scavenging capacities and total phenolic contents in grape juice. Our findings may provide evidence for the use of hydrocolloids for people at risk of nutritional deficiencies such as dysphagia patients.

The extract with the dilution of $50\%$ ethanol and treatment of $121^{\circ}C$ for 15min were inhibited highly the growth of staph aureus, Ent. cloacae, Sh. sonnei, A. hydrophila, b. subtilis, St. faecalis and L. casei. of food samples, red-bean dregs with addition of extact of smilax china. leaves or sorbic acid took the similar inhibition effect to microorganisms for the early storage days(1-3days). There was inhibited the growth of microorganisms in strawberry Juice added to 20m1 of $1\%$ extract solution for one storage day in comparison with no addition of smilax china L. Over all with growth inhibition capability to microorganisms and foods, it was believed that the effect and value as the natural food preservatives and the extracts like as this natural plant material took the food safety and it was capable to develop the natural food preservation.

본 연구에서는 붉은팥과 검정팥 종피에 함유된 천연색소에 대한 연구의 일환으로, 추출방법에 따른 색소 추출 효율과 저장안정제 첨가에 따른 저장 안정성과 특성을 검토하여 다음과 같은 결과를 얻었다. 1. 붉은팥 종피의 용액 추출 시 $50^{\circ}C$까지는 온도가 높을수록, 시간이 경과될수록 색소 추출 효율이 높게 나타났으나, $70^{\circ}C$에서는 시간이 경과될수록 색소 추출효율이 감소하는 경향을 보이며 pH 조건에서는 pH 5가 가장 효율적이었다. 2. 검정팥 종피의 용액 추출 시 온도가 높을수록, 시간이 경과될수록 색소 추출 효율이 높게 나타났으며, pH 조건에서는 pH 5가 가장 효율적이었다. 3. 착액 추출 시, 붉은팥의 경우 pH 5의 전처리가 증류수보다 색소 추출량이 많았으며, 검정팥의 경우 단시간 전처리에서는 증류수가 pH 5에서 보다 색소 추출량이 많았지만, 4시간 이상의 전처리에서는 오히려 pH 5에서 많게 나타났다. 4. 저장 안정제로 Methionine을 첨가한 결과에서는 붉은팥 종피의 경우에는 첨가량이 많을수록, 검정팥 종피의 경우에는 10mmol첨가가 20mmol 첨가보다 안정 효과가 큰 것으로 나타났다.

항산화성의 생리활성을 함유함과 동시에 기호성을 증대한 녹두전분 겔 제품 개발의 가능성을 검토하기 위하여 당근, 시금치 및 오디 생즙 각각을 첨가한 전분 겔의 품질 특성을 조사하였다. 무첨가, 당근즙, 시금치즙, 오디즙 첨가 전분 겔의 수분 함량은 첨가 재료에 따른 차이가 없었으며, 색상은 첨가재료의 색상이 전분 겔에 그대로 착색되었다. 경도는 무첨가 전분 겔에서 가장 높았으며, 탄력성, 응집성, 씹힘성 및 깨짐성은 당근을 첨가한 전분 겔에서 가장 높았으나 다른 첨가재료와 큰 차이는 없었다. 각각의 생즙을 첨가한 전분 겔의 전자공여능, 환원력 및 총 폴리페놀 함량은 생즙에 비해 다소 낮았으며, SOD 유사활성에서는 대등하거나 오히려 높은 활성을 나타내었다. 저장 기간에 따른 이수율은 당근, 시금치, 오디 즙을 첨가한 전분 겔이 무첨가 전분 겔에 비하여 낮은 이수율을 보였으며 특히, 오디 첨가구에서 가장 낮은 이수율을 나타내었다. 관능검사 결과, 천연 재료를 첨가한 전분 겔은 무첨가 전분 겔에 비해 색상, 향미, 맛이 우수하고 종합적 기호도가 높았으며, 특히 오디 첨가구에서 가장 높은 선호도를 나타내었다.

쑥즙을 옥수수, 녹두, 감자전분에 첨가하여 가열할 때 페이스트의 점도가 낮아지는 것으로 나타났으며 특히 감자전분에서 뚜렷하였다. 전분겔의 경도는 쑥즙 첨가에 의해 별로 영향을받지 않았으며, 전분의 노화도변화에서는 쑥즙 첨가로 감자전분의 노화도가 조금 증가하였다. 냉동-해동 안정성은 쑥즙 첨가로 변하지 않았다. 따라서 쑥즙을 첨가하여 전분겔을 제조하더라도 전분만으로 제조한 겔과 특성에는 차이가 없을 것으로 여겨지며 쑥 자체를 첨가할 때보다는 거친 섬유질이 제거되기 때문에 표면이 매끈하여 관능적 특성이 향상된 겔식품을 만들 수 있을 것으로 보인다.
