  • The preventive effect of chewing gum containing maltitol, xylitol, gum base, and sugar on remineralization were investigated. The clinical study consisted of 8 weeks' randomized, double blind, controlled, cross-over clinical trials including 24 healthy adults had chew gum. After each test week, remineralization effect was evaluated by measuring microhardness and scanning electron microscopy (SEM). Microhardness of experimental chewing gum containing maltitol or xylitol was significantly higher than that of sugar gum (p<0.005). Images of SEM showed the remineralization effect of gum containing gum base, maltitol, or xylitol compared with sugar gum. Maltitol and xylitol gums were more effective in remineralization than sugar gum. It was concluded that maltitol and xylitol can be used as sugar substitute to prevent dental caries.

  • Chemical components of Panax (P) species were compared. p. species used were Korean white ginseng, Korean, Chinese and Japanese red ginseng (P ginseng), American and Canadian ginseng (P. quinquefolium) , and sanchl ginseng (P. notoginseng). No significant difference in the proximate contents was observed among P. species. Ash, crude lipld and total sugar contents in root of P. notoginseng were found to be relatively lower than those of P. ginseng and P. quinquefolium, but the contents of crude protein and crude fiber were similar among those ginsengs. Mineral nutrient con tents showed a little difference among ginseng species. Total nitrogen contents were slightly higher in P. ginseng than P. quinquefolium and P. notoginseng and Fe and Cu were lower in Chinese and Japanese red ginsengs. Kinds and compositions of amino acids were similar but contents of amino acids were different among ginseng species. Total amino acid contents were 76.3∼83.9 mg/g in P. ginseng 53.8∼60.4 mg/g in p. quinquefolium and 54.9 mg/g in P notoginseng. Free sugar contents were lower in P. notoginseng than P. ginseng or P. quinquefolium. Sucrose accounted for 90∼92% of total free sugar contents with relatively high content in white ginsengs, while sucrose and maltose were 32-36% and 55∼60%, respectively, in red ginseng.

  • This study investigated the free sugar and free amino acids considered as the taste component in Korean Gochujang. Our goal was to search and develop the Korean traditional Gochujang taste, and to monitor the current status and characteristics of the Gochujang. For the analysis of Gochujang, it is purchased from small farms as well as major food company producing Gochujang. In the case of commercial Gochujang(COM), glucose and maltose were major free sugar, and the ratio of distribution and total amount showed very similar pattern. However, the results of the traditional Gochujang(TG) showed significant differences for each sample even they had glucose and maltose as predominant sugar. The content of glucose, maltose, fructose was reduced in order. The other hand, sucrose, rhamnose were not detected or were detected trace amounts in some samples. Even the characteristics were found at each region, it was no noticeable difference, but each sample was greater variation. Total of 17 amino acids were found from COM and the major amino acids were Pro, Glu, Asp, but His, Met were generally detected in small amounts. In the TG, they mainly contained Glu, Asp, Pro as the dominant component in addition to the Arg, Ala, Cys, respectively. TG had higher amino acid content and fairly various distribution compared to COM. It could suggest the possibility of the development for different traditional tastes because each TG had diverse characteristic taste than COM.

  • This study was conducted to investigate distribution of free sugas in the ginseng plant and change of free sugar content in dried ginseng with various drying conditions. The results obtained are as follows: 1. The total free sugar content is about 1% in the root and about 2% in the upland portions. Sucrose which accounts 80% in those free sugars, is 0.91% in main body 0.90% in raw ginseng, 0.74% in latheral root, 0.67% in head, 0.57% in skin, 0.64% in leaves, and 0.35% in steins. 2. Sucrose content is 3.3~4.6% in the ginseng root dried at temperature of 3$0^{\circ}C$ and 0.5 ~ 1% in the root dried it at temperature of 50-9$0^{\circ}C$. 3. Maltose was not present in fresh ginseng or dried ginseng which was dried under the t, but it was produced dried at the temperature above 5$0^{\circ}C$, it was 0.5% at 5$0^{\circ}C$, 1.49 %. at 7$0^{\circ}C$, and 4.03% at 9$0^{\circ}C$, respectively. This sugar Height be produced by endogenous saccharifying enzymes.

  • 돌외를 채취해서 잎과 줄기로 나누고 각각 실험실에서 차로 제조한 것과 제품으로 시판되고 있는 국산품과 일본산 제품 및 국산품 란은 것에 대해 총당, 환원당 및 유리당 함량을 측정하고 비교하였다. 제조된 돌외차의 총당과 환원당 함량은 줄기가 잎의 2배 많았으며 한국산 제품과 일본산 계품의 함량은 비슷하였으나 볶은 것은 볶지 않은 한국산보다 총당이 17.2% 감소하였으며, 환원당은 40.9% 감소하였다. 돌외차에 함유된 유리당은 rhamnose, fructose, glucose및 sucrose등이 확인되었다. 그 비율은 부위에 따라 차이가 많았으나 일반적으로 glucose> fructose> sucrose> rhamnose순으로 조성되었고 일본산 제품의 rhamnose 함량이 한국산 제품보다 6배 많았으며 볶은 것은 전체적으로 유리당 량이 낮았다.

  • 팥앙금과 설탕 및 물엿을 혼합한 모델용액에서 물엿농도 및 가열조건에 따른 팥앙금 호화액의 당 및 아미노산 함량의 동적변화를 모니터링 하였다. 중심합성계획에 의해 유리당 함량을 측정한 결과, 갈변반응이 심하게 발생한 실험구에서 glucose와 fructose의 함량이 높고, maltose의 함량이 낮게 나타났다. 또한 팥앙금 호화액의 amino acid 함량을 분석한 결과, total amino acid 함량은 가열온도에 가장 많은 영향을 받았고, 갈변반응이 많이 일어난 시료에서 그 함량이 크게 증가하였다. 각 시료의 갈색도 측정 결과 glucose 및 아미노산의 변화와 마찬가지로 $95^{\circ}C$의 온도까지는 그 함량이 감소하다가 그 이상의 범위에서는 가열온도가 높아짐에 따라 증가하였다. 팥앙금 호화액의 유리당 및 아미노산 함량과 갈색도와의 상관관계를 조사해 본 결과, 양의 상관관계를 나타내어 갈색도의 증가로 인한 유리당 및 아미노산의 감소보다는 열분해에 의한 유리당 및 아미노산의 증가 속도가 더 빠른 것으로 여겨진다.

  • The objective of this study was to analyze the free sugar contents of ten kinds of fruits and fruit vegetables that were collected from many district in Korea. The analyzed results will be used as basic nutrition component reference to processing. The results were summarized as follows. The total free sugar contents among the ten kinds of fruit vegetables was highest in grape. The contents of glucose, fructose and sucrose were 6.39%, 6.27%, 0.28%, respectively. The average total sugar contents of four cultivar of apple was 11.42% and average fructose contents was 6.13%. The free sugar contents of thirteen samples of the same cultivar of apple were all differing with statistical significance. The average total free sugar contents of eight cultivar of peach was 8.66%. In case of tomato, glucose content was approximately 1.35~2.83% and fructose was 1.26~2.51%. The contents of glucose, fructose and sucrose in paprika were 2.19%, 2.06%, 0.1%, respectively.

  • 복숭아 과실 부위별 유리당 축적와 효소와의 관계를 살펴보고자 2006년 8월에서 9월까지 '장호원황도' 복숭아의 과경부, 과정부, 과피부, 핵주위의 유리당 함량과 당 관련 효소활성 변화를 살펴보았다. 당도는 만개 후 150일까지 증가하는 경향을 나타냈고 과정부에서 가장 높은 당도를 보였으며, 모든 부위에서 총 유리당 함량은 당도 변화와 매우 유사하게 나타났다. 비교적 전분의 함량이 높았던 만개 후 120일에 과정부에서 높은 전분 함량을 보였으나 만개 후 150일에는 부위별로 함량 차이가 작게 나타났다. 부위별 유리당 조성의 변화는 시기에 따라서 차이를 보였으며 자당 함량은 만개 후 150일까지 점차 증가하였으나 솔비톨은 만개 후 130일 이후에 점차 감소하였다. 만개 후 150일까지 모든 부위에서 자당은 증가하고 반대로 포도당, 과당, 솔비톨은 감소하는 경향을 보였다. 또한, 과실 발육 동안 자당 함량의 증가는 sucrose phosphate synthase(SPS) 활성보다는 sucrose synthase(SS)활성에 의하여 더 많은 영향을 받는 것으로 나타났다. SS효소활성은 만개 후 120일에는 낮게 나타났으나 acid invertase(AI) 활성은 높았으며, 만개 후 150일에는 반대의 경향을 나타냈다. 따라서 유리당을 합성하거나 분해하는 효소의 활성에 따라서 복숭아 과실 생육시기별 축적되는 유리당 함량이 영향을 받았으나, 과실의 각 부위에 따라서 모든 유리당 함량을 관련 효소활성으로만 설명하기는 어려웠다.
