  • This study was attempted to investigate the physicochemical changes during soybean-leaf water kimchis fermentation by adding wheat flour in cooking water. Soybean-leaf water kimchis with five different levels of wheat flour in cooking water(0%;A, 5%;B 10%;c, 15%;D, 20%;E) were tested for rhological parameters, fine structural changes, sensory evaluations and chemical analysis. The composition of the soybean-leaf was moisture (80.9%), protein(6.8%), fat(0.6%), ash(2.1%) and alkalinity (+14.9). The amount of reducing sugars of sample A and other samples were 0.75% and 1.08∼1.4% in the initial fermentation stage, but decreased to 0.3 and 0.43∼0.50% in the later fermentation stage, respectively. The pH of sample A decreased from 5.17 to 4.72 during the initial fermentation. On sample B, C, D and E, pH's decreased rapidly during the initial fermentation, but they did not change much in the later fermentation stage. The pectin contents of all samples decreased during 2nd and 4th day of fermentation, then the change was slow. The amount of hemicellulose. cellulose and lignin in terms of the DNF and ADF were varied from 4 to 33%, but the contents of them did not greatly changed during the fermentation. The sensory evaluation showed that both B and C samples had the good score in sweety taste, roasted nutty taste, and the ease of swallowing measured as chewiness. From these results, the optimum soybean-leaf water kimchis can be prepared when 200g soybean-leaf, 1000$m\ell$ water, 15g garlic, 3% red pepper powder and 5 ∼0% wheat flour were fermented at 20$^{\circ}C$ for 2 days.

  • We investigated the physicochemical and sensorial properties of hamburger patties made with three different defatted soybean flour (DSF) preparations which differed in particle size. Coarse ($Dv_{50}=259.3{\pm}0.6{\mu}m$), fine ($Dv_{50}=91.5{\pm}0.5{\mu}m$), and superfine ($Dv_{50}=3.7{\pm}0.2{\mu}m$) DSF were prepared by conventional milling and sifting, followed by jet milling at 7 bars. Hamburger patties containing 5% of each DSF were prepared for a property analysis. The hamburger patties made with 5% superfine DSF showed the lowest cooking loss among the treatment groups (p<0.05). The patties with superfine DSF also retained the texture profile values of the control patties in terms of hardness, gumminess, springiness, and chewiness, while the addition of coarse and fine DSF increased the hardness and chewiness significantly (p<0.05). The sensorial results of quantitative descriptive analysis (QDA) indicate that the patties containing superfine DSF were softer and tenderer than the controls (p<0.05). Although the overall acceptability of the patties made with coarse and fine DSF was poor, the overall acceptability of the superfine DSF patty was the same as that of the control patty. These results suggest that superfine DSF is an excellent food material that can supply dietary fiber, while maintaining the physical characteristics and texture of hamburger patty.

  • 본 연구에서는 황토를 이용한 인견직물의 천연염색에 대한 연구의 일환으로, 인견직물의 카티온화가 이루어졌으며, 여러가지 염색조건 즉 염색온도, 염색시간, 염색 pH와 욕비에 따른 염착특성을 평가하여 적정 염색조건을 설정하였으며 이에 따른 염색된 인견직물의 견뢰도 평가를 통해 다음과 같은 결과를 얻었다. 수비법으로 얻은 황토분말의 입자 크기는 $0.4{\sim}1.7{\mu}m$ 범위로 나타났으며 $1.1{\sim}1.4{\mu}m$범위내의 분포가 가장 많은 것으로 나타났다. 황토성분을 분석한 결과, 이산화규소와 산화알루미늄이 많은 양을 차지하는 것으로 나타났다. 인견 직물의 암모늄기의 도입에 의한 양이온화는 FT-IR 흡수스펙트럼에서 $1,540cm^{-1}$ 부근의 N-H bending에 의한 출현 peak로 확인할 수 있었다. 염색 pH에 따른 K/S 값은 pH 8에서 가장 높게 나타났으며, 염색시간에 따른 K/S 값은 시간이 경과함에 따라 염색시간 30분까지는 급격히 증가하다가 그 이상의 시간에서는 거의 증가하지 않았다. 황토농도에 따른 K/S 값은 20% 이하의 농도에서는 약간 증가하지만 30%에서 최고값을 보여준 후 점차 감소하는 경향으로 나타났다. 콩즙의 전처리농도에 따른 K/S 값은 처리농도 30% 까지는 증가하였으나 그 이상의 농도에서는 오히려 약간 감소하는 경향으로 나타났다. 황토염색직물의 황토염착 분포 및 염착 상태를 관찰한 결과 황토 염색 농도가 증가함에 따라 황토입자의 부착량이 많아짐을 알 수 있다. 양이온화 처리에 의해서도 황토의 부착량이 증가하는 것을 볼 수 있으며, 콩즙을 처리하면 콩즙이 직물의 표면을 감싸는 모습을 볼 수 있으며, 콩즙을 처리하지 않은 시료에 비해 콩즙을 전처리한 시료에 더 많은 양의 황토입자가 부착되어 있는 것을 확인할 수 있다.

  • The intention of this study is to apprehend the con. tents and methods of herb remedies that are commonly conducted when there are health-problem cases of ENT, eyes, teeth and skin. Methods of this study are divided into two stages : 1) For a period of six months from December 1994 to June 1995, some 40 persons who are believed to be well versed with herb remedies have been randomly chosen, and we made a survey on herb remedies by symptoms: and 2) we have endeavored to make their grounds evident through the studies on literatures with the focus on the basic data collected. Their results are as follows: 1) When one feels a pain in ears, such herb remedies are employed as pouring the vapor into ears, which is made by steaming Alaska pollack, or as applying or wiping with the juices of radish or the ginkgo, or' alum. Applying the radish juice is effective for sterilization and fever removal: and applying the ginkgo juice is effective for cleanliness. But, plastering alum, sesame oil or castor oil, or pouring the vapor of Alaska pollack into ears are perhaps effective but do not have any pharmacologic grounds. 2) When one bleeds at the nose, such kinds of herb remedies are applied as stimulating nose or head with cold water, pressing nose or ridge of nose, or filling up nares with mashed mugworts. In addition, they have utilized garlic or leeks. Such methods as stimulating with cold water or just pressing nose and ridge of nose is based on reasonable grounds, i.e. vasoconstriction and vascular compression ; and applying mashed garlic on the sole of foot is good for the circulation of Qui ; and the use of mugworts and leeks is based upon the pharmacological function of hemostasis. 3) When one feels a sore throat such kinds of herb remedies are employed as gargling or rinsing throat with brine, drinking hot gruel or water, or drinking the juice of mugwort, radish, ginger or Chinese quince. Gargling with brine or drinking the juice of mugwort, radish or ginger is based upon the pharmacological function of pain alleviation, fever removal, and detoxication. 4) When a boil is formed in mouth, such herb remedies are applied as spreading honey, brine or alum water, and taking gall nut, Chinese matrimony vine, lotus root, etc, for drugs. Spreading honey, brine or water that is made by infusing gallnut, Chinese matrimony vine, lotus root is based upon such functions as hematosis, astriction, antibacterial, and antiphlogistic, Alum, eggplant and licorice are said to be effective, but their pharmacological effects have no grounds. 5) When one has conjunctivitis such herb remedies are commonly applied as irrigation with brine and dropping breast milk in eyes. Moreover, such other drugs are used as plantain. shepherd's purse, and purslane, etc. The use of brine, breast milk, plantain, shepherd's purse and purslane is based upon such functions as sterilization, antiphlogistic, disinfection and pain relieving. Eriocaulon sieboldianum, bean stem, bean pod and narcissus leaves are said to be effective, but their pharmacological action have no basis. When one has a stye, such herb remedies are applied as extracting eyelashes, stimulating by a massage of middle finger, third finger or big toe, as well as sear ing with a heated bamboo comb that is fine-toothed. Other than these, plantain and nightshade's nuts are used as drugs for it. Extracting eyelashes corresponds with exclusing suppurative node and draining the stye of pus ; and the use of plantain is based upon disinfection: and nightshade's nuts are said to be effective, however, their pharmacological action has no grounds. 6) For a treatment of toothache, such herb remedies are commonly employed as rinsing mouth with brine and holding cold water or gasoline in the mouth ; and as the drugs that are believed to be effective have been Welsh onion, ginger and castor-oil, plant, etc. The use of Welsh onion is based upon pain killing, antiinflammatory actions, and the use of ginger is based upon detoxication and disinfection ; and seeds of castor-oil plants are said to be effective, but they have no pharmacological basis. 7) When one has hives, such herb remedies are commonly applied as rubbing burned straw in affected parts, exposing to its smoke, rubbing with salt, sweeping down with a broom, and spreading and drinking boiled water of trifoliate orange. The use of cassia tora seeds, walnut, aloe and radish is said to be effective. The use of cassia tor a seeds has the functions of intestinal order, anti-paralysis, etc. The use of walnut has resulted in an increase of blood by invigorating spirits ; and the use of aloe is based upon disinfection, antibiotic, anti-salt, antihistamine and detoxication action. But, the effects of radish juice and straw's smoke have no pharmacological grounds. 8) When one gets a boil, such herb remedies are commonly used as applying a plaster, paste of flour mixed with yolk, soy sauce or honey, as well as spreading pounded elm tree. Other remedies that have been said to be effective are ; heating with mugwort, brine, wild rocambole, aloe, onion, squid's bone, etc. The use of mugwort is based upon pain killing, astringent antiinflammatory and tranquility. Wild rocambole is based upon the generation and maintenance functions of cell-joining textures ; elm tree upon antiphlogistic ; aloe upon fever removal and antiphlogistic ; onion on pain killing, fever removal, antiphlogistic and tranquility ; squid's bone on astriction: and brine or vinegar on sterilization. Pine resin and gardenia seed are said to be effective, but they have no pharmacological basis. 9) When one cuts his skin, such herb remedies are commonly employed as spreading mugwort's juice or squid's bone powder, or pressing the wounds. In addition, kalopanax, onion and fine soil are employed. The use of mugwort, kalopanax and squid's bone is based upon such functions as hemostasis, sedation, pain killing, antibacterial ; and fine soil is said to be effective, but it has no pharmacological basis. 10) When one suffers from whitlow, such herb remedies are commonly utilized as heating with boiled soy sauce, spreading soybean paste, or dipping into eggs, etc. Other drugs that have been employed are onion root, brine, eggplant, potato, loach, etc. The use of onion is based upon pain killing and antiphlogistic functions ; and that of brine upon antiphlogistic function. The use of soy sauce or soybean paste, fomentation, eggplant, potato and loach is said to be effective, but it has no pharmacblogic ground. 11) For the treatment of frostbite, such herb remedies are commonly used as dipping the affected part into frozen soybean sack, using boiled water of eggplant stem, garlic caulis, onion, hot pepper, caulis. Onion is based upon antiphlogistic and tranquility actions garlic upon disintection, metabolic exacerbation, tonic and aphrodisiac actions and the use of eggplant and hot pepper is based upon help blood circulation, dissolution and excretion of waste matters in vein. 12) For the treatment of burn, such herb remedies or drugs are commonly used as cleansing with Korean gin, spreading eggs, cleansing with cold water and soap water ; and as brine, cactus, moss, soybean paste, oil, etc. The cleansing with Korean gin, cold water, soap water, brine, vinegar is based upon cleaning and sterilizing functions ; and the use of cucumber is based upon nu. trition provision, and strengthening of resisting power by adjustment of metabolism. The use of potato, cactus, moss, oil and eggs is said to be effective, but their phamacological functions are not clarified. In view of the above results, we can realize that the drugs that have been employed in herb remedies are quite diverse. However, in regard to majority of herb remedies that have been employed by symptoms, the pharmacological functions of their drugs have not been clarified, and they are merely known as effective. Furthermore, they have not been recorded in the literature as yet ; and we confirm that there have been many herb remedies that were executed without the proper knowlege of their effects. It is now our view that the results of this survey may be utilized for consulting data in regard to the use of herb remedies.
