This study was conducted to investigate the characteristics of nonstarchy polysaccharides in Korean ginseng, (Panax ginseng C.A. Meyer). The results obtained are as follows. 1. The total sugar content of ginseng roots were decreased with increasing the cultural period. On the other hand, the crude fiber content was increased with that of the ginseng leaves or stems. But the crude fiber in root was much less than that of leaves and stems. 2. The dietary fiber content of ginseng root on 5 years old was 14.20% as neutral detergent fiber, 9.08% as acid detergent fiber, hemicellulose 5.12%, cellulose 7.98% and lignin of 1.10%, respectively. 3. Much more pectin was found in ginseng roots which was cultivated for shooter Period. And it was contained much more in the root than in the leaves and stems. 4. ginseng hemicellulose content in root was 5% to 10%. It was decreased with increasing: cultivated period. Hemicellulose was constituted of xylose, arabinose, glucose, rhamnose and xylose of these sugars was the predominant. 5. X-ray diffraction Pattern of ginseng cellulose showed maximum intensity at tile interplanar angle of 4.1$^{\circ}$.

Contents of insoluble(IDF), soluble dietary fiber (SDF), and total dietary fiber(TDF) of 30 foods which are consumed commonly by 80 Koeran male college students were determined by Prosky and colleagues' enzymatic-gravimentric method. Foods with highest intake frequency were rice, Kimch'i, and red pepper powder. TDF, IDF, and SDF contents of rice were 0.96, 0.59 and 0.37g/100g wet wt., respectively and tose of Kimch'i were 3.07, 2.19 and 0.88g/100g wet wt., respectively. Red pepper powder contained high amount of TDF(39.37) and IDF (33.13g/100g wet wt.). The TDF content of the 30 foods ranged from 0.70 to 39.37g/100g wet wt. Red pepper (39.37), dried laver(31.36), and dried sea mustard (37.77g/100g wet wt.) contained high amounts of TDF. The IDF content of the 30 foods ranged from 0.13 to 33.13g/100g wet wt. Red pepper powder (33.13), dried laver(15.55) and sesame(15.43g/100g wet wt.) contained high amounts of IDF. SDF of the 30 foods ranged from 0.01 to 25.66g/100g wet wt. Dried sea mustard(25.66), dried laver(15.81), coffee powder (13.17), and garlic(8.72g/100g wet wt.) were good sources of SDF. % ratio of SDF to TDF of the 30 foods was lower than 50% except soybean curd(94.27%), coffee powder (88.93%), garlic(86.17%), dried sea mustard(67.94%), and dried laver(50.41%). It is recommended to increase intake of seaweeds in order to supply TDF adn SDF properly.

Sugar snap cookies were prepared with the addition of carrot powder (2~12%) as a source of dietary fiber. Analyses of physiochemical properties, rheology and sensory evaluation of the cookies were conducted. Increasing carrot powder content weakened the flour, as evidenced by decreased diameter and increased thickness, which resulted in decreased spread factor. The water content of the carrot powder-amended cookies and unamended flour was not significantly different. The pH and L values progressively decreased and a and b values progressively increased with increasing addition of carrot powder. Textural analysis revealed no significant differences in brittleness with carrot powder addition, even though brittleness did decrease with the addition of more carrot powder. Sensory evaluation revealed a preference for cookies prepared with 2~4% carrot powder, with decreased preference at powder concentrations exceeding 6%. Addition of a dried vegetable with high fiber content caused the dietary fiber to absorb much water content, resulting in decreased diameter, increased thickness and decreased spread factor. Therefore, it is deemed desirable to increase the spread factor by controlling the water content and adding emulsifiers so as to enhance the functionality and maintain the quality of cookies.

The effect of dietary fiber enrichment (wheat bran) and cooking methods (oven, steam and microwave) on functional and physico-chemical properties of raw nuggets formulation as well as nutritional, color and textural properties of chicken nuggets were analyzed in this study. Among different cooking methods used for nuggets preparation, steam cooked nuggets had significantly (p<0.05) higher water holding capacity (56.65%), cooking yield (97.16%) and total dietary fiber content (4.32%) in comparison to oven and microwave cooked nuggets. The effect of cooking methods and wheat bran incorporation was also noticed on textural properties of the nuggets. Hardness, firmness and toughness values of oven and steam cooked nuggets were significantly (p<0.05) higher than microwave cooked nuggets. Among nuggets prepared by different cooking methods, cohesiveness of microwave cooked nuggets was found to be significantly (p<0.05) highest, whereas, oven cooked nuggets had significantly (p<0.05) highest gumminess and chewiness values. Steam cooked nuggets were found to be better among all nuggets due to their higher cooking yield and dietary fiber content.

식물성 섬유질 함유 자원으로부터 식품의 가공적성을 떨어뜨리지 않으면서 우수한 기능특성을 보이는 식이섬유원을 제조할 목적으로 대량 수급이 용이한 사과쥬스박과 두유박에 식이섬유의 함량을 높이고 기능성을 향상시키기 위한 각종 처리를 행하여 식이섬유원을 제조하였다. 사과쥬스박은 마쇄, 수세 및 사별에 의하여 사과육과 사과피로 분리할 수 있었는데 사과육이 사과피보다 기능성이 우수하였고 사과육은 수세, n-hexane 처리 등에 의해 WHC 11.27 g/g, FHC 2.01 g/g, CEC 64.96 meq/100g의 기능성을 보이며 60.94%의 NDF를 함유한 제품을 제조할 수 있었다. 두유박을 이용한 식이섬유원 제조에서는 수세, n-hexane처리, 산처리, 알칼리처리 등의 처리로 WHC 10.15 g/g, FHC 1.52 g/g, CEC 63.72 meq/100g의 기능성을 보이며 52.66%의 NDF 함량을 갖는 식이섬유원이 제조되었다. 이때 원료로부터의 회수율은 사과육의 경우 약 30%, 처리두유박의 경우는 38.2%이었다. 식이섬유질원의 색도는 수세시 명도를 효과적으로 증가시킬 수 있었으나 유기용매, 산 및 알칼리 처리에 의해서는 명도가 감소하였다.

배추 매매후 발생하는 배추 쓰레기의 양이 매우 많으며, 현재 거의 전량이 폐기되어 환경에 많은 부담을 주고 있다. 서울 가락동 시장의 경우 매일 약 355톤 이상(전체 쓰레기 발생량의 64.1%)의 배우 쓰레기가 배출되고 있다. 따라서 단순 폐기 처분되는 폐자원을 수거하여 유용 물질을 생산한다면, 쓰레기 처리라는 환경 보호 측면과 폐기 비용 절감, 자원 재활용 측면에서 매우 중요하다. 본 조사 연구에서는 배추 쓰레기의 발생 현황, 식이 섬유소의 일반적 특성 및 배추 쓰레기로부터 고부가가치의 식이 섬유소(Dietary Fiber)로의 전환을 검토해 보았다. 배추 쓰레기에서의 식이 섬유소 함량을 측정한 결과 기존의 알려진 값(0.7%)보다 더 높은 수치(2.5%)를 나타냈다. 또한 식이 섬유소 추출 과정에서 효소 amylase와 protease의 영향은 없었다.

This study was aimed to investigate the nutritional components such as proximate content, minerals, vitamins, and dietary fiber of Euonymus sieboldiana leaves. The leaf sample used was fresh material produced in April in the Republic of Korea. As a result, the fresh leaf sample contained 10.30% crude carbohydrates, 7.42% crude proteins, 0.69% crude fat, and 1.46% crude ash, including a high amount of potassium (0.73%). The total dietary fiber, insoluble dietary fiber, and soluble dietary fiber content was 8.77%, 7.60%, and 1.17%, respectively. Vitamin C was found to be 44.53 mg% using colorimetric analysis. We regarded E. sieboldiana as a potential health food material because of its abundant nutritional components like potassium, dietary fiber, and vitamin C.

추청과 수천 두 품종의 벼에서 얻은 미강에 함유된 총 식이섬유를 AOAC방법으로 정량하였고, acid detergent fiber(ADF) 방법으로 식이섬유의 성분을 분석하였다. 미강의 식이섬유 함량은 25% 이상이었고 대부분 불용성이었다. 미강 식이섬유의 주성분은 헤미셀룰로오스이었으며 상당량의 셀룰로오스와 uronic acid가 특징적으로 함유되어 있었다. 화학적 처리에 의한 가용성 식이섬유(SDF)의 함량과 보수력(WHC)의 변화를 측정한 결과, 산과 알칼리를 연속적으로 처리한 경우에 SDF함량과 WHC가 뚜렷하게 증가하였다. 미강 식이섬유의 기능성을 조사하기 위하여 밀가루에 미강 식이섬유를 여러 가지 함량으로($0{\sim}100%$) 첨가하고 WHC를 측정한 결과, 식이섬유의 첨가량에 비례하여 밀가루의 WHC가 증가하였다. 또한 differential scanning calorimetry(DSC)로 얻은 thermogram으로부터 미강 식이섬유는 전분의 노화를 지연시킴을 알 수 있었다.

In this study, we evaluated the effects of dietary fiber extracted from Algelica keiskei Koidz on the chemical composition, cooking characteristics, and sensory properties of chicken patties. The chicken patties with Algelica keiskei Koidz dietary fiber had significantly higher moisture and ash content, and yellowness than the control sample (p<0.05). Energy value, cooking loss, reduction in diameter, reduction in thickness, lightness, redness, hardness, cohesiveness, gumminess, and chewiness of the control samples was significantly higher than chicken patties with Algelica keiskei Koidz dietary fiber (p<0.05). The sensory evaluation indicated that the greatest overall acceptability in chicken patties was achieved at Algelica keiskei Koidz dietary fiber levels of 1% and 2%. Chicken patties supplemented with 2% Algelica keiskei Koidz dietary fiber had improved quality characteristics.

식이성 섬유를 첨가하여 케익을 제조하고 저장기간 중의 수분함량, 호화도, 경도의 변화를 측정한 결과를 요약하면 다음과 같다. 식이성 섬유의 첨가는 수분 함량과 호화도의 감소를 억제시켜주며 cake hardening rate도 감소시켜 주었다. 그리고 1등품 밀가루를 2등품 밀가루로 대체하면 섬유소 첨가와 유사한 효과를 얻을 수 있으며 여기에 펙틴을 첨가하면 보다 현저한 상승효과를 얻을 수 있었다. 새로운 조성으로 제조한 케익의 색도와 관능적 품질도 유의성 있는 차이를 나타내지 않았다.
