The fractionation of green juice could be one of the ways to treat the green juice for saving the bio re-sources by using the basic processes of protein coagulation and separating juice coagulation into protein paste and brown juice and storing the final products. The fractionation of Chinese cabbage juice can be accomplished by applying the combine method of the formic acid with rate of 0.3% and the propionic acid with rate of 0.1 % added 4 hours later in the juice with maximum recovery of protein coagulation. The separation of coagulation into the protein paste and the brown juice completed in 6.5 hours by set up method in a special designed storage. The protein paste could be stored safely for 30days in anaerobic condition.

Natural dyes are environmentally and human compatible. But they are not various or not fast in color. The mixed dyeing have been attempted to solve these disadventages of natural dyes. The persimmon juice dyed fabrics have brown-color and good hygienic properities however low color fastness. The onion dyeing show similar brown-color and have good color fastness caused by querectin existed in onion outer skins. Mixed dyeing was carryied out on silk fabrics using persimmion juice and onion outer skin extract in this study. The mixing method were persimmon juice dyeing and then onion dyeing(P-O), onion dyeing and then persimmon juice dyeing(O-P) and dyeing in the mixture of persimmon juice and onion outer skin extract simultaneously(P+O). The mordants were none-mordent, gallic acid after-treatment and alum after-treatment. Several persimmon juice dyed fabrics were irradiated for 2 hours before onion dyeing(PU-O). The color values of dyed silk fabrics were as follows. The persimmon juice dyed silk fabric developed to yellow-red color after 2 hours of uv irradiation. Onion dyed fabrics show similar yellow-red color after dyeing without uv irradiation. The effect of alum after-treatment on color difference were highest in onion dyeing. The dyeabilities of both P-O and O-P were higher than persimmom juice dyeing and onion dyeing. The dyeabilities of P+O was lower than persimmom juice dyeing and onion dyeing. The value of color difference of alum-treated fabric was the highest. The color difference of P-O and O-P caused from 2 to 4 hours of uv-irradiation were lower than those of persimmon juice dyed fabrics. Onion skin extract could prevent the color-change of persimmon juice dyed fabrics in mixed dyeing. The color difference of PU-O was higher than the P-O.

The natural dyeing of fabrics with persimmon juice(astringent persimmon, sweet persimmon, astringent and sweet persimmon mix) was investigated. After dyeing of cotton and silk fabrics with persimmon juice, we evaluated the dyeability of persimmon juice, the observation of fabric surface with high magnification video microscope, physical properties and color fastness with the conditions of repeating times of dyeing and variables of mordants. The results obtained from this study were as follows: The fabrics dyed with astringent persimmon have shown the highest color difference, while the fabrics dyed with sweet persimmon and the fabrics dyed with astringent and sweet persimmon mix have shown similar color differences. With the increase of repeating times of dyeing, the brightness of fabric decreased. However, $a^*$ value increased gradually, so that it became dark brown color. The $a^*$ and $b^*$ values of dyed fabrics with Fe-mordant have dropped significantly, so that they have shown achromatic colors. But the fabrics treated with other mordants have shown yellowish brown colors. On the surface of the fabrics, threads were bonded together by the viscosity of persimmon juice. Regardless of the types of persimmon juice, stiffness was increased after dying, while crease resistance was decreased. The water repellency of silk fabrics were improved than cotton fabrics after dyeing with sweet persimmon juice, but in case of cotton, it hasn't changed. Washing fastness was improved with the EM(Effective Microorganism)-fermented liquid treatment, and rubbing fastness of two fabrics was better in dry condition than in wet condition.

Effect of pre-treatment with hot water extract of marine brown alga Sargassum polycystum C.Ag. (100 mg/kg body wt, orally for period of 15 days) on HCI-ethanol (150 mM of HCI-etha-not mixture containing 0.15 N HCI in $70\%$ v/v ethanol given orally) induced gastric mucosal injury in rats was examined with respect to lipid peroxides, antioxidant enzyme status, acid/pepsin and glycoproteins in the gastric mucosa. The levels of lipid peroxides of gastric mucosa and volume, acidity of the gastric juice were increased with decreased levels of antioxidant enzymes and glycoproteins were observed in HCI-ethanol induced rats. The rats pre-treated with seaweed extract prior to HCI-ethanol induction reversed the depleted levels of antioxidant enzymes and reduced the elevated levels of lipid peroxides when compared with HCI-ethanol induced rats. The levels of glycoproteins and alterations in the gastric juice were also maintained at near normal levels in rats pre-treated with seaweed extract. The rats given seaweed extract alone did not show any toxicity, which was confirmed by histopathological studies. These results suggest that the seaweed extract contains some anti-ulcer agents, which may maintain the volume/acidity of gastric juice and improve the gastric mucosa antioxidant defense system against HCI-ethanol induced gastric mucosal injury in rats.

The purpose of this study is to investigate the effect of mulberry juice on the quality characteristics of mulberry jelly. Samples of mulberry jelly were divided into four groups by adding different mulberry juice. The four groups were divided into MJ-0 (mulberry jelly without mulberry juice), MJ-30 (mulberry jelly with 30% mulberry juice), MJ-50 (mulberry jelly with 50% mulberry juice) and MJ-70 sample (mulberry jelly with 70% mulberry juice). The moisture content in all MJ samples decreased with an increase in the addition of mulberry juice. The highest crude ash content, brix and pH in MJ-70 sample were 0.66%, 25.00 °Brix and 4.84, respectively. No significant crude fiber changes were observed in all MJ samples. In the case of Hunter's value, 'L' values in all MJ samples decreased with an increase in the addition of mulberry juice. Turbidity, brown degree, total phenolic content, DPPH radical scavenging activity and content increased with an increase in mulberry juice. Levels of Ca, K, Na, and Mg contents in all samples were higher than those of the other minerals. Texture in all MJ samples on the whole decreased with an increase in mulberry juice added. However, no significant texture charges were observed in all samples. The highest scores for the overall acceptance (4.52) were found in the MJ sample with 50% mulberry juice.

Unripe indigenous persimmons which contain rich tannins have been used as natural dye materials traditionally and have been using continuously for dyed clothes named Gal-ot in Jeju. Those persimmons were cheap and easy to use as dyes because of inedible and widely cultured in Korea. Persimmon juice dyes not only make fabrics brown-color but also give functional and hygienic properities such as stiffness, air ventilation of clothes, antibacterial activity, protectivity against ultraviolet light. However there are several serious problems which are ristriction of dyeing periods, longtime irradiation, uneven color and low color fastness etc. in persimmon juice dyeing. This study purpose to improve dye effect and method in order to enlarge useability of persimmon juice dyeing. Cotton fabrics were pad-dyed to 100% pick-up using padding machine after dipping in persimmon juice extracted from unripe persimmons indigenous from Jeju. It was possible and available to control pick-up rate. The color of dyed cotton fabrics by padding method was more even and repeatable than which by traditional hand method. Persimmon juice concentrations were 4 types of 10, 25, 50 and 100％. The more concentration increased, the more color deepened. UV Irradiation instead of sunlight was applied to color developing. Irradiation times were shortened till 1∼8 hrs. Same color values could be taken without water wetting which were required in sunlight irradiation. Tensile strengths of cotton fabrics pad-dyed with low concentration of persimmon juice decreased but recovered at high concentrations. Elongations(％) of cotton fabrics pad-dyed with persimmon juice were increased 1％ more than undyed cotton in sunlight irradiation. Drape stiffness increased upto double times as much as.
