돼지고기의 콜레스테롤 함량 감소에 관한 β-Cyclodextrin의 급여효과
박병성,Park, Byung-Sung 한국식품영양과학회 2006 한국식품영양과학회지 Vol.35 No.3
The main objective of the present study was to determine the effect of dietary ${\beta}-cyclodextrin\;({\beta}CD)$ on reducing the cholesterol content of pork. Twelve swine of 50 kg body weight were randomly distributed into four groups of three heads each and fed experimental diets for 9 weeks until they reached a market weight of 110 kg. They were assigned to the four experimental diets containing 0% (control), 1.5%, 3.0% or 5.0% pure ${\beta}CD$. Daily feed intake, body weight gain and feed efficiency were not significantly different between any of the four group. The plasma total lipid, triacylglycerol and total cholesterol content of the swine in the three ${\beta}CD$-fed groups were significantly (p<0.05) decreased when compared to those in the control group, and were significantly (p<0.05) reduced by 21.80%,55.58% and 27.69%, respectively, in the swine fed on 5% ${\beta}CD$. The cholesterol content of pork belly (mg/100g) was significantly (p<0.05) decreased by 5.33 mg, 12.70 mg and 15.23 mg in the swine maintained on 1.5%, 3.0% and 5.0% ${\beta}CD$, respectively. The cholesterol content of pork belly, when expressed as the rate of reduced cholesterol, was significantly (p<0.05) decreased by 6.44%, 15.36% and 18.42% in groups of 1.5%, 3.0% and 5.0% ${\beta}CD$, respectively, when compared to that of the control group. These results suggest that dietary ${\beta}CD$ may be classified as dietary fiber which can modulate cholesterol metabolism in swine. 본 연구의 주목적은 돼지고기의 콜레스테롤 함량 감소에 관한 사료 내 ${\beta}CD$의 급여 효과를 조사하는 것이었다. 생체중 50 kg의 3원교잡종 거세 수퇘지 12마리를 이용하여서 4처리구 3반복으로 완전임의배치한 후, 시판체중인 110 kg 도달시까지 약 9주 동안 실험사료를 급여하였다. 일일 사료섭취량, 일일 증체량 및 사료효율은 ${\beta}CD$를 첨가하지 않은 대조구와 비교할 때, ${\beta}CD$ 1.5%, 3.0% 및 5.0% 첨가구의 각 처리구간 통계적인 유의차가 나타나지 않았다. 혈액 총지질, 중성지방 및 총콜레스테롤 함량은 대조구와 비교할 때 ${\beta}CD$ 첨가구가 유의적으로 낮아졌으며, 특히 ${\beta}CD$ 5.0% 첨가구에서 각각의 감소율은 21.80%, 55.58% 및 27.69%로서 가장 높게 나타났다(p<0.05). 돼지고기 삼겹살의 콜레스테롤 함량은 대조구와 비교할 때 ${\beta}CD$ 1.5%, 3.0% 및 5.0% 첨가구에서 각각 5.33mg, 12.70mg및 15.23 mg의 유의적인 감소를 나타났으며, 특히 이 값을 콜레스테롤의 감소율로서 나타냈을 때 각각 6.44%, 15.36%, 18.42%로서 유의적인 차이를 나타냈다(p<0.05). 이 결과는 돼지에서 ${\beta}CD$첨가급여가 콜레스테롤 대사를 조절할 수 있는 식이섬유로서 사용될 수 있음을 시사해준다.

소나무껍질 추출물(피타민)을 섭취한 닭고기의 품질 및 저장성
박병성,Park, Byung-Sung 한국축산식품학회 2009 한국축산식품학회지 Vol.29 No.4
A component of pine bark extract, pitamin, is known as an antioxidant and antimicrobial agent that exerts a variety of physiological effects; this compound has also been used widely in human beings. A 35-day trial was conducted to determine the influence of dietary pitamin premix via a sensory evaluation and evaluations of the TBARS, and meat quality in broiler chicken. We used 4 treatments groups: Control, Antibiotics, Pitamin premix 0.1%, and Pitamin premix 0.2%. The amino acid and protein contents in chicken breast muscle did not differ among the treatment groups. The pH of broilers fed on diets containing pitamin premix was lower (p<0.05) than broilers fed on the control and antibiotics diets, whereas the WHC was significantly higher in chicken breast muscles fed on the diet containing pitamin premix compared to the control and antibiotics groups (p<0.05). The TBARS is intended to be increased during the storage period (in days), and was significantly lower (p<0.05) in the chicken thigh muscles with skin from broilers fed on the diet containing the pitamin premix as compared to the control and antibiotics group (p<0.05). The sensory evaluation of boiled chicken, with the exception of the antibiotics group, revealed significantly better results from chickens fed on diets containing pitamin premix than the control group (p<0.05). These results suggest that dietary pitamin premix may improve the shelf life, flavor, taste, and meat quality in broiler chicken.

박상오Sang-Oh Park,박병성Byung-Sung Park,노가영Ga-Yeong Noh 한국유화학회 2014 한국응용과학기술학회지 Vol.31 No.4
This study was determined the hair growth effect and mode of action of a complex extract (abelmo), extracted from various natural plants including Acorus calamus var. angustatus. 30 six-week old C57BL/6 mice were randomly assigned into three treatment groups with ten mice per treatment group repeatedly. The treatment group is a control group, and was classified into saline-applied, minoxidil 5%-applied, and abelmo-applied groups. Hair growth started from the abelmo-applied and minoxidil 5% -applied groups on the 9th day, compared to the saline-applied group. Hair growth rate was 17.06% and 19.15% in those two groups, respectively, and the abelmo-applied group s hair growth rate was higher. The density, length and thickness of hair were significantly higher in the order of abelmo-applied group, minoxidil 5%-applied group and saline-applied group on the 9th day, and hair root was strongly maintained in the abelmo-applied group. The density, length and thickness of hair in the abelmo-applied group were significantly higher by 599.8, 122.2 and 181.8% on the 9th day compared to the saline-applied group, and 166.7, 171.4 and 200.2% on the 12th day, and 136.6, 216.9 and 180.7%, respectively on the 15th day. As for hair follicle and the length of hair shaft from the dosal skin histopathology manifestation, the abelmo-applied group was more excellent than the saline-applied group and minoxidil 5%-applied group. This result actually confirmed the fact that abelmo promotes hair growth and strongly maintains hair root simultaneously.

브로일러에서 계피의 첨가급여가 브로일러의 성장능력, 혈액지질, 도체특성, 닭고기의 품질특성 및 계피맛, 향과 관련한 닭고기의 맛에 미치는 영향을 연구하였다. 병아리는 CNP를 함유하지 않은 대조구, CNP 2.0%, CNP 3.0%, CNP 4.0% 및 CNP 5.0% 첨가구로 구분하였다. 브로일러의 사료 섭취량, 사료효율은 대조구와 비교할 때 처리구간 차이가 없었으나 체중은 CNP 3% 이상으로 첨가수준이 증가함에 따라서 유의적인 개선을 나타냈다(p<0.05). 혈액의 중성지방, HDL-C는 대조구에 비해서 CNP 첨가수준이 높아질수록 증가하는 경향을 나타냈으나, 총 콜레스테롤, LDL-C는 뚜렷하게 감소하였으며 각 처리구간 통계적 유의차가 있었다(p<0.05). 도체율은 CNP 첨가구가 대조구에 비해서 높았고, 닭 다리살은 CNP 3.0% 이상에서 증가하였으며, 닭 가슴살은 CNP 2.0%와 4.0% 첨가구가 높은 경향이었다(p<0.05). 닭 가슴살의 pH는 대조구와 비교하여 유의차가 없었으나, 보수력은 CNP 4% 이상 첨가수준이 높아질수록 증가하였고, TBARS는 CNP 3% 이상 첨가수준이 높아질수록 유의적으로 낮아졌다(p<0.05). 닭 가슴살의 육색은 CNP 첨가수준이 3% 이상 증가할수록 대조구에 비해서 더욱 밝은 색을 나타냈다(p<0.05). 닭 다리살 튀김과 삶은 닭 가슴살에서 계피와 관련한 맛, 향에 대한 관능평가 성적은 대조구와 비교할 때 CNP 첨가수준이 높아질수록 유의적으로 높게 나타났다(p<0.05). 본 실험에서 나타난 중요한 점은 브로일러 사료에 계피를 첨가 급여해줌으로써 닭고기의 도체특성과 맛을 개선할 수 있다는 사실이었다. A 35-day trial was carried out to determine the influence of dietary cinnamon powder (CNP) on the sensory evaluation and quality of chicken meat, carcass characteristics, plasma lipid level and growth performance of broiler chickens. There were 5 treatment groups: control; CNP 2.0%; CNP 3.0%; CNP 4.0%; and CNP 5.0%. The body weight of the broilers fed the diets containing 3.0% CNP was higher than the broilers fed the control feeds (p<0.05). The concentration of triacylglyceride, HDL-C was higher in the plasma from broiler chickens fed diets with CNP (p<0.05) but the concentrations of total cholesterol and LDL-C were significantly lower (p<0.05) compared to the control group. The carcass percentage, chicken breast and thigh weight were not different between the CNP and control groups. The WHC was significantly higher in the chickens fed 4% CNP diet, while the TBARS was significantly lower (p<0.05) in the chickens fed 3% CNP diet compared to the control group. The color of the breast muscle from the chickens fed 3% CNP diet was lighter than those from the control groups (p<0.05). The sensory evaluation of the taste and savor related to CNP in fried or boiled chicken meat were significantly better from the broiler chicken fed diets containing CNP than the control group (p<0.05). These results suggest that dietary cinnamon powder may improve savor and quality of chicken meat in broiler chickens.

난황 콜레스테롤 및 계란 품질에 관한 식이내 베타 - 사이클로덱스트린의 효과
박병성(Byung-Sung Park) 한국식품영양과학회 2004 한국식품영양과학회지 Vol.33 No.4
본 연구의 주목적은 난황 콜레스테롤 함량 및 계란 품질에 관한 식이내 베타사이클로덱스트린(βCD)의 효과를 조사하는 것이었다. 29주령 산란계 100마리를 이용하여 각각 20마리씩의 5그룹으로 나누어서 완전임의 배치하였으며 실험 10 주기간 동안에 각각의 산란 케이지 내에서 수용하였다. 산란계의 식이는 순수한 βCD를 0, 3, 5, 7 또는 10% 함유하는 5개의 처리구로 나누었다. 암탉의 식이섭취량, 산란율, 난중은 βCD 무첨가구와 βCD 3, 5, 및 7% 첨가구 사이에 서로 비슷하였으나 βCD 10% 첨가구는 유의적으로 낮아졌다(p<0.05). 식이요구율을 계란 1개당으로 표시했을 때 식이내 βCD 첨가수준과 차이는 없었으나 βCD 10% 첨가구에서 유의적으로 손상되었다(p<0.05). βCD 첨가는 호우유니트, 난황색 및 난각두께에 아무런 영향을 주지 않았다. 난황 g당 콜레스테롤 함량은 βCD 무첨가구와 비교할 때 βCD 3, 5, 7 및 10% 첨가구에서 각각 3.76, 5.12, 5.49 및 6.48 ㎎씩 유의적으로 낮아지는 경향을 보였다(p<0.05). 계란 60 g당 콜레스테롤 함량은 βCD 무첨가구와 비교할 때 βCD 3, 5, 7 및 10% 첨가구에서 각각 54, 71, 77 및 86 ㎎으로 감소하는 경향이었다(p<0.05). 가장 획기적인 효과는 산란계 식이내 βCD 5%와 7% 첨가구에 의해서 난황 콜레스테롤 함량이 각각 28.19% 및 30.23%까지 감소한 관찰이었다. 이상의 결과로 βCD의 첨가 급여는 난황의 콜레스테롤 함량을 낮출 수 있으며 콜레스테롤 함량이 낮아진 기능성 계란을 생산할 수 있을 것으로 본다. This study was to determine the effect of dietary β-cyclodextrin (βCD) on egg quality and cholesterol content of egg yolk. One-hundred 28-week-old laying hens were randomly distributed into five groups of twenty hens each and maintained in individual laying cages for 10 weeks of the experiment. They were assigned to the five treatments of experimental layer diets containing 0, 3, 5, 7 or 10% pure βCD of diets. Food intake, egg production and egg weight varied slightly and insignificantly in the hens fed with 0, 3, 5 or 7% βCD-added diets. But food intake, egg production, and egg weight were uniformly lower (p<0.05) in the hens fed with 10% βCD-added diets. Food conversion rate, when expressed per number egg, was impaired (p<0.05) without having an obvious relation to the dietary βCD level. No difference in haugh unit, egg yolk color, and egg shell thickness was found among treatment. The cholesterol content of egg yolks was significantly decreased (p<0.05) to 3.76, 5.12, 5.49 and 6.48 ㎎/g yolk in βCD 3, 5, 7 and 10% treatments respectively when compared to that of the βCD 0% group. The cholesterol content of eggs, when expressed in ㎎/60 g egg, was greatly(p<0.05) decreased to 54, 71, 77 and 86 ㎎ in βCD 3, 5, 7 and 10% treatments when compared to that of the βCD 0% group. The most striking effects (p<0.05) were observed in βCD 5% and 7% treatments, whose cholesterol content decreased from 28.19% to 30.23%. In conclusion, βCD added-diets fed to laying hens can reduced the cholesterol content of egg yolk, and this new type of egg yolk with lower cholesterol can be considered a functional livestock food.
