This experiment was carried out to find the quality characteristics of yanggaeng added antioxidant rich collagen powder in the color, sugar contents, texture, radical scavenging activity and electronic nose detected flavor. L value and a value kept decreased as the more collagen powder was added in the yanggaeng while b value was increased significantly at the same time. Sugar contents was increased significantly from $43^{\circ}$Brix in the control to 48% in the 10% treatment (p<0.05). Hardness in the 10% treatment of collagen powder increased biggest among the treatments but springiness decreased when hardness increased. And adhesiveness, cohesiveness, gumminess and chewiness were also increased with more the collagen powder in the treatments, therefore 10% treatment showed biggest result significantly. Radical scavenging activity kept increased with higher addition of collagen powder and it resulted 60% of radical scavenging activity in the 10% treatment. In the flavor test under electronic nose experiment, 10% of collagen powder treatment was believed it flavored most for it was found in the furthest from the AIR location. Control was found also in the nearest from the AIR, which meant it has least flavor than any other treatment. Also 2.5% and 5% of collagen powder added treatments showed little differences of flavor from control, which meant 5% of treatment was believed idea condition in the treatments. With the above experimental results, 5% of collagen powder treatment in the yanggaeng manufacturing was chosed as the best mixture ratio in the test.

Objectives: The aim of this study was to confirm the dose-dependent skin moisturizing effects of dried pomegranate concentrate powder (PCP) and pomegranate concentrate solution (PCS) in ICR mice. Materials and methods: To observe the in vivo skin moisturizing effects and possible underlying mechanisms of PCP and PCS, oral PCP (100, 200, and 400 mg/kg) and PCS (1, 2, and 4 mL/kg) were administered to normal ICR mice. Changes in body weight, skin water content, and skin type I collagen and hyaluronan contents were measured. Additionally, the mRNA expression levels of hyaluronan synthase (Has) 1, 2, and 3, and collagen type I alpha (COL1A) 1 and 2 were determined in the dorsal skin of mice by real-time reverse transcription polymerase chain reaction (RT-PCR). Results: Significant and dose-dependent increases in dorsal skin water content and type I collagen and hyaluronan contents were seen in PCP and PCS-treated mice. Moreover, the mRNA levels of Has 1, 2, and 3, involved in hyaluronan synthesis, and of COL1A1 and COL1A2, involved in collagen synthesis, were significantly and dose-dependently upregulated in PCS- and PCP-treated mice. Conclusions: In this study, PCP and PCS led to favorable skin moisturizing effects as indicated by increased skin water content and the upregulation of hyaluronan and collagen synthesis enzymes in mice treated with PCS (4 mL/kg) and PCP (200 mg/kg).

어린 콜라겐의 동결건조 혼합분말 첨가에 따른 칼국수의 품질 특성
정유민(You Min Jung),방은정(Eun Jung Bang),강성태(Sung Tae Kang) 한국식품영양과학회 2015 한국식품영양과학회지 Vol.44 No.3
본 연구는 어린 콜라겐 500 g, 액상의 식용식물 추출물 375g, 덱스트린 125 g을 물 1,000 mL에 녹여 1:0.75:0.25:2의 비율로 제조한 후 동결건조한 다음 분쇄하여 제조한 어린 콜라겐 동결건조 혼합분말(freeze-dried collagen mixture powder, FDCMP)을 0.5, 1.0, 1.5 및 2.0% 비율로 칼국수 반죽에 첨가하여 제조한 칼국수의 품질 특성을 분석하여 FDCMP의 첨가가 칼국수의 품질 특성에 미치는 영향을 조사하였다. 조리 후 칼국수의 중량과 부피는 FDCMP 첨가량이 많을수록 낮게 나타났고, 칼국수 삶은 물의 탁도는 유의적인 수준으로 FDCMP 첨가구가 높게 나타났다. 수분결합 능력은 밀가루와 물보다 FDCMP와 물의 수분 결합 능력이 높게 나타났다. 색도는 조리 전후의 칼국수에서 FDCMP 첨가량이 많을수록 명도 L값은 감소하고 적색도 a값과 황색도 b값은 증가하였다. 기계적 조직감 측정은 조리한 칼국수의 경도와 씹힘성는 FDCMP 첨가량이 증가할수록 감소하였으며, 점착성, 응집성과 검성은 FDCMP 첨가량이 증가할수록 증가하였다. 탄력성과 복원성은 FDCMP 첨가 시 대조구와 유의적인 차이는 없었다. 관능검사 결과에서는 대조구보다 FDCMP 0.5% 첨가구가 조직감, 입 안에서의 느낌, 종합적인 기호도가 높게 나타났다. 따라서 칼국수 개발 및 품질향상을 위한 어린 콜라겐 동결건조 혼합분말의 첨가는 0.5%가 가장 적당하다고 사료된다. This study investigated the quality of noodles added with different amounts of freeze-dried fish scale collagen mixture powder (FDCMP). Freeze-dried fish scale collagen mixture was prepared by mixing ingredients (fish scale collagen : herb extracts : dextrin : distilled water=1:0.75:0.25:2), which were freeze-dried. Noodles were prepared by adding 0.5, 1.0, 1.5, and 2.0% (w/w) FDCMP based on flour weight. Cooked noodle weight and volume decreased with increasing amount of FDCMP, whereas turbidity of soups significantly increased. The water-binding capacity of FDCMP was higher than that of flour. Uncooked and cooked noodles showed reduced L values as well as increased a and b values increasing amount of FDCMP in the flour composite. Hardness and chewiness of cooked noodles significantly decreased with increased FDCMP content. Adhesiveness, cohesiveness, and gumminess increased with increased FDCMP content. Springiness and resilience were not significantly different between the control and FDCMP group. Finally, sensory evaluation results indicated that texture, mouthfeel, and overall preference of noodles containing 0.5% FDCMP were higher compared to those of the other samples. Based on cooking properties and sensory evaluation, freeze-dried fish scale collagen mixture powder up to 0.5% could be substituted for wheat flour to improve noodle quality.
