The effect of dietary xylitol on growth performance and nitrogen retention was studied in male broiler chicks during immunological stimulation. In experiment 1, chicks (10 day of age) were fed a corn-soybean diet containing 10% glucose or 10% xylitol with identical metabolizable energy and crude protein for 14 days. In experiment 2, ten-day-old chicks were fed 10% glucose or 6% xylitol diet for 8 days. During the final 6 days of the experimental periods, a half of birds fed each diet were injected intraperitoneally with 0.5 mg/kg body weight of Escherichia coli lipopolysaccharide (LPS, 0127:B8) on days 1, 3 and 5, and with 250 mg/kg body weight of Sephadex-G50 superfine on days 2 and 4 to stimulate immune system in both experiments. Feeding of the xylitol diets partially prevented the reduction in body weight gain or feed efficiency due to LPS and Sephadex injections, but the glucose diet did not in both the experiments. LPS and Sephadex injections decreased nitrogen retention, whereas the diet containing xylitol partly in experiment 1 and almost completely in experiment 2, prevented the reduction due to immunological stimulation. These results indicate that dietary xylitol probably prevents the reduction in nitrogen retention with growth retardation due to LPS and Sephadex injection. The beneficial effect on nitrogen retention is obtained when chicks are given xylitol 2 days before stimulating the immune system.

현재까지, 식이 당의 전체적 또는 부분적 대체당으로서 자일리톨의 치아우식증에 대한 예방 효과를 확인하기 위해 많은 연구가 수행되었다. 본 총설논문에서는 자일리톨의 구강건강에 대한 기존 연구들을 바탕으로 자일리톨의 치아우식증 예방 기전, 치아우식증 예방, 치아우식증 유발균의 모자전염 예방, 노인의 구강건강에 미치는 영향 등이 정리되었다. 식품에 함유된 탄수화물 및 식이 당은 구강 내에서 산을 생성하는 미생물에 의해 발효되어 치석 및 산을 생성하여 치아우식증을 일으킨다. 그러나 충치를 일으키는 세균 대부분은 자일리톨을 대사하여 산을 만들어 낼 수 없다. Streptococcus mutans (S. mutans)에 의한 비대사성 대사물로서 세포 내에 축적된 자일리톨은 S. mutans의 성장을 억제하고 치석 형성을 억제하여 치석과 타액 중 S. mutans 수를 감소시킨다. 또한, 자일리톨은 치아의 재광화(remineralization) 과정에 작용한다. 자일리톨은 치아우식증 예방, S. mutans의 모자감염 예방, 노인의 충치예방 및 타액분비 증가에 효과가 있는 것으로 확인되었다. 결론적으로, 자일리톨은 남녀노소 구분 없이 구강건강에 효과적이며 쉽게 섭취할 수 있는 장점이 있다. 향후, 자일리톨의 과량섭취에 따른 부작용과 구강 및 장내 환경에 미치는 전반적인 영향에 대한 보다 정확하고 상세한검토가 필요하다.

The effects of xylitol and/or erythritol as the alternative ingredients to sugar on the quality characteristics of Yuza tea were studied. The relative sweetness of xylitol and erythritol to a 10％ sucrose solution were 1.10 and 0.71 respectively and there were no change after the addition of the acid and flavoring agent. The sensory characteristics of Yuza tea with xylitol were quite similar in many attributes to Yuza tea with sugar, while Yuza tea with erythritol had many undesirable attributes. Yuza tea with a mixture of xylitol and erythritol(1:1) was less sweet and less acceptable than Yuza tea with sugar. The consumer acceptance test showed that the overall acceptability of Yuza tea made with xylitol was similar to the Yuza tea with sugar. Adding sucralose to the Yuza tea with a mixture of xylitol and erythritol improved the sweetness and overall acceptability in the consumer acceptance test. The pH value of the erythritol Yuza tea was 3.16 and showed a significantly lower value than the 3.39 of sugar and xylitol. The refractive index of the sugar Yuza tea was the highest at 21.03$^{\circ}$Bx. The vitamin C content of Yuzachung with sugar was 34.5mg/100g and the dietary fiber content was 2,80g/100g. Xylitol Yuzachung showed the highest a and b values, but when it was diluted with water to make Yuza tea, the intensity of the color was not significantly different from the Yuza tea with sugar.

The effects of sweeteners(fracto-oligosaccharide: xylitol: erythritol: stevioside) as alternative ingredients to sugar on the characteristics of yanggeng were investigated. The relative sweetners of fracto-oligosaccharide, xylitol, erythritol and stevioside to a 25% sugar solution were found to be 25%, 25%, 22.5% and 0.25% respectively. Sensory evaluation to compare yanggeng made using fracto-oligosaccharide, xylitol, erythritol and stevioside to a 100% sugar yanggeng revealed that they differed by 37.5%, 37.5%, 33.75% and 0.75% respectively highlight. The viscosity of yanggeng differed depending on the type of sweetener used. Sugar contents(°Brix) were the highest in sugar. The moisture contents were the highest in yanggeng made with 0.75% stevioside, while the hardness, adhesiveness, chewiness and gumminess were highest in that made with 33.75% erythritol. The springiness was highest in yanggeng made with 37.5% fracto-oligosaccharide, while the cohesiveness was highest in that made with 37.5% xylitol, and the L-values, b-values and a-values were lowest in yanggeng made with 25% sugar. Sensory evaluation, revealed that the overall preference was highest for yanggeng made with 37.5% fracto-oligosaccharide and xylitol.

We developed a dietary supplement using natural herbs and nutrients for the growth and exercise performance improvement. It called 50-22 supplement containing distilled extracts of natural herbs to remove bitterness and the addition of Vitamin B1, B6, Ca and xylitol. We investigated on the effect of 10-22 supplementation on the maximal exercise performance, IGF-1 (insulin like growth factor-1) concentration and antioxidant activity in SD rat model. In result, JR-22 supplement group was better than control group about 10％ in exercise performance test and increased about 63％ of IGF-1 concentration in blood. In addition, the oxidative damage induced by exercise was reduced by JR-22 supplementation. Therefore, we suggested that 50-22 supplementation enhanced effectively exercise performance and IGF-1 concentration and reduced to oxidative stress in muscles. Also, we analysed biochemical factors in blood for the safety of JR-22 supplement. We known that there is no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity. (Korean J Community Nutrition 8(3) : 349∼355, 2003)

오미자는 유기산 함량이 5~7%로써 대단히 높기 때문에 기호성이 우수한 과일주를 제조하려면 희석이 불가피하다. 본 연구에서는 오미자를 희석하는데 향기와 총산 함량이 적고 당분이 풍부한 배를 이용하였는데, 오미자와 배를 1:9~1:15로 희석할 경우, 일반 과일주의 총산 농도인 0.6~0.7%와 비슷하게 되었다. 오미자 배 혼합 발효주의 경우 오미자의 붉은색이 엷어지는데, 이러한 적색을 보정하기 위하여 복분자와 개량머루 발효주를 적용한 결과, 복분자 발효주의 색상이 오미자 색상과 비슷한 것으로 판명되었다. 오미자 배혼합 발효주의 적색도 보정용으로 복분자 발효액을 첨가할 경우, 무게 비율로 3~5% 첨가시 오미자의 붉은색 이미지에 적합한 것으로 나타났다. 오미자 배 혼합 발효주의 쓴맛을 완화시키면서 단맛을 부여하며 효모에 의한 2차 발효를 방지하기 위한 방법으로 비발효성 당인 자일리톨을 첨가한 결과, 오미자 배 혼합 발효주에 대하여 자일리톨을 2~5% 첨가한 것이 기호성이 우수한 것으로 나타났다.

The present investigation was undertaken to study the effects of non-genetic factors and association among replacement and lifetime production traits. The data on 542 Holstein Friesian cows maintained during 1975-98 at State Cattle Breeding Project, Sector III, Hisar, were utilized. The average sex-ratio, abnormal births, mortality, culling and replacement rates on total calf born and total female calf born basis were 51.62, 8.50, 17.52, 31.05, 22.78 and 51.41 per cent, respectively. The study revealed that a minimum of 4 to 5 progenies are required per cow over its lifetime to replace itself. It indicated that each cow should produce a minimum of 2 female calves during its life so as to replace herself before being lost. The least-squares means for productive herd life, longevity and lifetime production were $1439.32{\pm}87.64$ and $2419.18{\pm}8.25$ days and $11317.95{\pm}913.15kg$, respectively. The heritability estimates for all replacement traits were very low indicating that sire selection may bring no desirable change in these traits. Heritability estimates were $0.178{\pm}0.157$, $0.288{\pm}0.184$ and $0.096{\pm}0.195$ for corresponding lifetime production traits. Breeding values and ranking of sires were generated for replacement and lifetime production traits to estimate the rank correlations between these traits. Moderate desirable rank correlations were obtained between replacement rate and lifetime production traits indicating that sires proven on the basis of milk production are also expected to have better replacement rate.

본 연구에서는 떫은감의 대표적인 품종인 대봉감과 반시의 일반성분 및 영양성분을 분석하고 비교하였으며, 대봉감과 반시의 재배지역별 영양성분의 특성을 살펴보았다. 다양한 영양성분은 품종에 따라 다른 함량을 나타냈는데 대봉감 품종은 불용성 식이섬유, 베타카로틴, 과당, 자당, 만니톨, 칼륨, 사과산, 호박산, 총 페놀화합물이 반시 품종에 비해 유의적으로 높은 함량을 나타냈으며, 반대로 반시 품종은 수분 함량, 조단백질 함량, 비타민 C, 칼슘, 망간, 주석산, 총 플라보노이드 함량이 대봉감 품종에 비해 유의적으로 높은 함량을 보였다. 재배지역에 따라 많은 성분들이 유의적인 차이를 나타냈다. 다른 지역에 비해 비교적 높은 함량을 보이는 영양성분은 A지역은 베타카로틴, 솔비톨, 만니톨, 아연, 총 페놀화합물, B지역은 조지방 함량, 리코펜, 자당, 자일리톨, 사과산, C지역은 호박산, D지역은 수분 함량, 망간, 탄닌, E지역은 조단백질 함량, 나트륨, 망간, 칼슘, 주석산, 총 플라보노이드 함량이었다. 이상의 결과로 떫은감은 품종이나 재배지역에 따라 많은 영양성분의 유의적인 차이를 나타낸다는 것을 확인하였으며 이런 차이는 떫은감을 활용한 가공제품 생산 시 고려되어야 할 사항으로 생각된다.
