오현경,임현숙,Oh, Hyun-Kyung,Lim, Hyeon-Sook 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.6

본 연구는 생다시마를 주성분으로 제조한 가공제품이 배변활동과 장 내용물의 대장통과시간에 미치는 영향을 알아보기 위해 수행되었다. 만성 기능성 변비 증세를 지닌 연구대상자 32명의 자발적인 참여로 이루어졌다. 이들 연구대상자를 8명씩 4개 실험군으로 나누어 2주간 1일 3회 식간에각각의 실험물질을 섭취하도록 하였고, 6주간의 휴지기간을둔 후, 다시 2주간 동일한 실험물질을 급여하였다. Control군은 150 mL의 생수를 3회 섭취하도록 하였고, +Control군은 생수 150 mL 이외에 생약 성분의 변비약을 취침 전에 1회복용하도록 하였으며, STT군은 생다시마차를 150 mL에 타서 3회 음용하도록 하였고, STB군은 150 mL로 포장된 생다시마음료를 섭취하도록 하였다. 총 대장통과시간 측정은 방사능 비투과성 표지자($Kolomark^{TM}$)를 3일간 매일 아침에 섭취하도록 한 후 4일째에 단순 복부 엑스선 촬영을 하여구하였다. 본 실험결과, 연구대상자 스스로 판정한 자신의 배변활동은 생다시마차의 섭취로 변비가 개선되었다. 1차 실험에서 생다시마차의 섭취는 배변횟수증가, 배변시 힘주기 강도, 배변량 증가, 잔변감의 감소 및 주요 배변 시간대의개선 등 유의성 있는 효과를 보였다. 2차 실험에서는 비록 구체적 항목에서는 유의한 차이가 나타나지 않았지만 배변활동의 평균 점수가 유의하게 낮아져 역시 배변활동 개선효과를 나타내었다. 생다시마차의 배변활동 개선 효과는 생약제재의 변비약을 복용한 효과와 거의 같았다. 이외의 배변활동 항목인 대변의 굳기, 배변시 힘주기 및 배변 소요시간에 있어서도, 유의성은 없었으나 개선의 추세를 보였다. 이러한 점으로 미루어 생다시마차가 생다시마 음료에 비해 변비 개선 효능이 좀 더 낮다고 판단된다. 방사선 비투과성 표지자의 총 대장통과시간은 +Control군만 1차와 2차 실험모두에서 유의하게 감소되었다. 이는 예상했던 결과와 같으며 시중에서 판매되는 식이섬유를 주성분으로 하는 변비약이 결장의 운동기능을 향상시켜 장 내용물의 대장통과시간을 단축시킨 것이라고 해석된다. Control군은 1차 실험에서는 +Control군과 근사한 정도로 총 대장통과시간을 단축하는 효과를 보였으나 2차 실험에서는 아무런 효과도 보이지 않았다. 이러한 결과는 생수의 음용 시 온도가 1차와 2차실험 간에 달랐기 때문이 아닌가 추측된다. 본 실험결과로 미루어 볼 때 하루에 3회씩 냉장온도의 생수를 150 mL씩 섭취하는 것은 결장의 운동기능을 향상시키는 효과가 시판되는 변비약과 비슷한 정도라고 해석된다. 예상과는 달리 STT군과 STB군에서는 총 대장통과시간이 감소하는 경향은 보였으나 유의성은 없었다. 이는 배변활동이 개선되었다고 응답한 결과와 일치하지 않았다. 그러나 대장통과시간의측정 방법이 갖는 제한점을 생각할 때 생다시마차와 생다시마 음료의 동 개선 효능은 인정된다. 생다시마차나 생다시마 음료도 1차 실험 때에는 차가운 상태로 음용했는바 차가운생수만큼 총 대장통과시간의 단축 효과가 나타나지 않은 점은 본 연구결과만으로는 해석하기 어렵다. 아마도 생수와 여러 물질의 혼합용액의 온도가 장에 끼치는 자극에 차이가 있지 않나 추측되며 이에 관한 추후 연구가 요망된다. 총대장통과시간의 단축은 결장 분절 모두에서 줄어들어 나타났으나 좌측결장 통과시간의 감소 및 이로 인한 이 부위의 통과시간 비율의 저하가 가장 주요하였다. 이러한 결과 This study was performed to investigate effects of raw sea tangle products on idiopathic constipation. A total of thirty-eight women participated voluntarily in this study. They were placed into one of four groups by their total colonic transit time (TCTT) to make the four groups have the same TCTT. In the first trial, the subjects in Control group were fed 3 times of 150 mL of mineral water per day for 2 weeks, those in +Control group were fed a kind of stool softener as well as the same mineral water for 3 times, those in STT group were fed 3 times of 150 mL of sea tangle tea and those in STB group were fed 3 times of 150 mL of sea tangle beverage. After 6 weeks, a second trial was performed for another 2 weeks. Although the TCTT of the group exposed to of KolomarkTM was not significantly reduced, the subjects in STT group answered that their evacuation activities were significantly improved; evacuation frequency was increased, stool hardness was reduced, evacuation straining was lessened, stool amount was increased, incomplete sense of evacuation was lessened, and major evacuation time was improved like those in +Control group. The results imply that it is worthy to develop some products of raw sea tangle such as STT, which are effective in treating or preventing constipation.

This study was conducted to develop patties by substituting a portion of meat by bamboo (Sasa borealis) leaf extract (SBE) and/or cooked rice. Four types of patty were prepared: Control, S, SI, and SII. S was the patty for which 2.5% of meat was substituted with SBE. SI and SII were the patties with 25% or 50%, of meat, respectively, substituted with cooked rice containing SBE. The moisture contents of S, SI, and SII patties were not changed. The compositions of fat, cholesterol, and protein of S, SI, and SII patties were decreased. Cooking loss of weight as well as the diameters of S, SI, and SII patties were decreased. pH was increased in S patty, hardness was reduced in SI and SII patties, and malondialdehyde values were lowered in S, SI, and SII patties, compared to control. The S, SI, and SII patties were evaluated higher for color in sensory tests and preference tests. Through preference tests of burgers with these patties, the overall taste of the SI patty was assessed highly among the 4 patties. Therefore, it may be concluded that developing a patty by substituting a portion of meat with SBE and/or cooked rice may be worthwhile.

This study created hamburger patties by substituting a portion of the meat with sea tangle (Laminaria japonica) powder and/or cooked rice to reduce fat and calories and to add the functional components of the sea tangle. Four types of experimental patties were prepared: Control, L, LI, and LII. L was the patty with sea tangle powder substituted for 2.5% of the meat and LI and LII were patties with cooked rice containing sea tangle powder substituted for 25 or 50% of the meat. In all experimental patties, moisture content increased and crude fat and cholesterol content decreased, pH increased, and malondialdehyde concentration decreased compared to those in the control. The substitutions made the color of the patties darker with dimmed redness and amplified yellowness. The substitutions also made the cooking loss weight and diameter of the patties lessen but that of thickness increased. In the sensory evaluation, symmetry and color of the patties improved significantly by substituting sea tangle powder and/or cooked rice for meat, and no adverse effect on preference for the experimental patties and hamburgers was observed. Therefore, substituting sea tangle and/or cooked rice for a portion of the meat could be used to develop healthier patties without any adverse influence on preference or sensory evaluation.

본 실험에서는 한방 재료를 이용한 건강 기능성 식빵의 제조 가능성을 알아보고자, 우선 보혈제의 기본 처방인 사물탕을 첨가하는 경우 식빵의 품질에 어떤 영향을 끼치는 지 검토고자 하였다. 사물탕은 당귀, 백작약, 숙지황 및 천궁을 각각 4.68 g씩 혼합하여 $120^{\circ}C$에서 3시간 동안 탕재하였다. 식빵 반죽 시 첨가하는 물의 25%(S-I), 50%(S-II), 75%(S-III) 또는 100%(S-IV)를 사물탕으로 대체하여 4종의 사물탕 첨가 식빵을 제조하였다. 본 실험 결과, 식빵 반죽의 pH는 사물탕 첨가로 유의하게 낮아졌는바, 식빵 반죽의 발효에 보다 적합한 환경을 제공한 것으로 판단된다. 식빵 반죽의 젖은 글루텐 함량은 사물탕 첨가로 유의하게 높아져 역시 식빵 적성을 개선하는 효과를 보였다. 식빵 반죽의 색도에 있어, 명도는 사물탕 첨가로 점차 유의하게 낮아진 반면에 적색도와 황색도는 유의하게 높아졌다. 식빵 반죽의 무게와 식빵의 무게는 사물탕 첨가에 따른 유의한 영향을 받지 않았으며 따라서 식빵의 굽기 손실율도 영향을 받지 않았다. 식빵의 모양 및 부피와 비용적 등 식빵의 형태적 특성은 사물탕 첨가로 유의성 있는 차이를 보이지 않았다. 식빵의 수분함량은 사물탕 첨가로 유의한 차이를 보이지 않았으나, 단백질과 회분함량은 유의하게 높아졌다. 사물탕 첨가는 반죽의 색도뿐만 아니라, 식빵의 속 색도에도 유의한 영향을 끼쳤다. 즉, 사물탕 첨가로 식빵 속의 명도는 낮아졌고 황색도와 적색도는 높아졌다. 텍스쳐 측정 결과, 사물탕 첨가는 식빵의 경도를 증가시켰으나 부착성, 탄력성 및 응집성에는 영향을 끼치지 않았다. 저장 3일과 5일에 식빵의 수분함량은 유의성은 없었으나, 사물탕 첨가 식빵은 감소 정도가 작았다. 식빵의 X-선 회절도는 사물탕의 첨가에 따른 영향을 보이지 않았다. 관능평가 결과 사물탕 첨가는 식빵의 대칭성, 맛, 경도 및 기공성에는 영향을 끼치지 않았으나, 식빵의 겉과 속의 색을 어둡게 하였고, 이취를 높였으며, 부피감과 점착성을 유의성있게 증가시켰다. 그러나 부피감과 점착성의 향상은 물론 어두운 색과 이취는 긍정적으로 평가되어 전체적인 기호도는 물의 50%를 사물탕으로 대체한 식빵이 가장 높았다. 본 연구결과는 물 대신 사물탕을 사용해 식빵을 제조하는 경우 제빵 적성 및 식빵의 품질을 개선시킬 수 있고 기호성을 향상시킬 수 있음을 시사한다. 따라서 혈액순환과 조혈기능을 촉진하는 건강 기능성 식빵으로서의 개발 가능성이 있다고 판단된다. It has been known that Samultang has positive effects on blood circulation and erythrocyte formation. Samultang was composed of four ingredients, Angelica gigas Nikai, Rahmanniae Radix Preparata, Paeonia lactiflora Pallas, and Cnidium officinale Makino. Five types of bread were prepared by replacing water with Samultang for dough proportionally. Control (C) did not have Samultang and the other four experimental bread contained Samultang: S-I (25% of water was substituted by Samultang), S-II (50% substituted), S-III (75% substituted), and S-IV (100% substituted). Moisture, protein, and ash contents of Samultang were $97.34{\pm}0.11%,\;0.42{\pm}0.04%,\;and\;1.40{\pm}0.16%$, respectively. Replacing water with Samultang decreased pH and increased significantly wet gluten content of the dough. Substitution of Samultang for water incremented redness and yellowness of the dough and bread and increased hardness. It also raised the contents of ash and protein. Although it was not significant, in addition, moisture loss of the bread during storage seemed to be lessened by replacing water with Samultang. However, total volume and specific loaf volume of the bread, baking loss rate, and the other textural characteristics except hardness were not affected by substituting water with Samultang. Due to the above results, sensory evaluation of volume and gumminess of the bread were improved significantly by substituting Samultang for water. The bread replaced 25% of the water with Samultang was ranked as the best by the test of sensory evaluation. These results imply that adding Samultang instead of water to dough for bread might bring positive effects on quality characteristics of the bread without any adverse influences. Therefore, it might be worth developing functional bread using Samultang.
