This study was carried out to investigate of the quality characteristics of the starch Oddi Dasik(MSOD) manufactured with various addition levels (0, 5, 10, 18 and 28%) of mulberry fruit (Oddi) juice (MFJ), with various levels(55%, 50%, 45%, 37% and 27%) of sucrose syrup, and with the ratio of rice powder: mungbean starch (1:4) according to the traditional Korean Dasik (a kinds of cookie) methodology. The nutritional components of Oddi and MSOD were examined, and sensory evaluation and physical tests of MSOD added MFJ were conducted. The results are summarized as follows. In Oddi, the contents of moisture, crude fat, crude protein, crude ash, and vitamin C, and the levels of acidity, pH and sugar were 88.45%, 0.245%, 2.23%, 0.88%, 53.20 mg%, 8.00%, 4.41 and 11.0 Brix%, respectively. In MSOD (Oddi 10%), the contents of moisture, crude fat, crude protein, and crude ash, were 22.8%, 0.117%, 9.2% and 0.8%, respectively, and were all increased with increasing MFJ amount. In MSOD (Oddi 10%), the contents of Ca, Mg, K and Fe were 63.2 mg%, 70.9 mg%, 376.0 mg% and 7.7 mg%, respectively. and were increased with increasing MFJ amount. For the establishment of the additional amount of MFJ, sensory evaluation and physical tests were conducted. From the total characteristics of sensory evaluation, the MSOD with 10% MFJ was judged as the best. Color L and b values of MSOD significantly decreased and a value increased with increasing MFJ percentage. Hardness, gumminess, adhesiveness and chewiness among the texture characteristics of MSOD were significantly increased with increasing MFJ amount. However, there were no significant differences in springiness and cohesiveness of the MSOD. In conclusion, the optimal added amount of MFJ for the manufacture of the MSOD was proposed to be 10% of the total weight.

The aims of this study were to develop and standardize the manufacturing procedures and ingredient formulation of non-fried, extrusion-puffed Yukwa. The quality and storage stability of the non-fried Yukwa (NF) were characterized and compared against a traditional deep-fried Yukwa (F). The moisture contents of both the NF and F were almost comparable at 5.12${\sim}$6.22% after the final product preparation. The textural hardness values of the NF samples were one-half to two times as hard as those of F, although no clear distinctions were reported between the two products by the sensory evaluation results (p<0.05). During storage, the acid value of F was 1.68 KOH mg/g on day 7, and then it rapidly increased to 5.52 KOH mg/g on day 14. In contrast, the acidity values of NF were 1.21 and 2.62 KOH mg/g on day 7 and 14, respectively. The peroxide values of the samples increased from 23.5 to 62.0 meq/kg (F) and from 2.0 to 2.5 meq/kg (NF) during the two weeks of storage after preparation, suggesting excellent fat stability for the NF product. Regarding the sensory evaluation results of the products, no significant (p<0.05) differences were noted between F and NF with scores of approximately 3.1 out of 5.0 points for the overall quality characteristics of the final products. Accordingly, we conclude that extrusion puffing technology could be adopted as an alternative to conventional deep fat frying as a partial manufacturing process of Yukwa.

본 연구는 실험을 통하여 마늘이 저염 멸치젓의 숙성에 미치는 영향을 검증하기 위하여, 생멸치 중량에 식염을 20% 첨가한 멸치젓을 대조군으로 하고 실험군은 식염을 각각 10% 첨가한 후 마늘분쇄물과 즙의 첨가량을 2, 5, 8, 10%로 달리하여 제조한 후 숙성 30, 60, 90, 110일에 시료를 취하여 관능검사와 이화학적 성분분석을 행하였다. 실시한 결과 다음과 같이 나타내었다. 관능검사 결과 씹힘성은 숙성기간이 증가함에 따라 유의적으로 감소하는 경향을 나타내었고. 감칠맛은 숙성 110일까지 유의적인 증가를 보였다. 마늘냄새는 숙성기간이 증가함에 따라 감소하는 경향을 나타내었으며 숙성 60일 이후로는 마늘냄새를 거의 느낄 수 없었고 부패취는 마늘냄새와 대조적으로 숙성기간에 따라 증가하는 경향을 나타내었다. 황색도는 대조군에 비하여 마늘 첨가군들이 유의적으로 높았다. 관능검사 결과는 마늘의 첨가량이 많을수록 부패취의 생성 억제 효과가 뛰어났으며 그 첨가량에 관계없이 60일 이상 숙성시키면 마늘의 향기성분은 대부분 휘발하였고 숙성 90일경이 관능적으로 가장 우수한 시기로 판단된다. 멸치젓 숙성 중 수분과 조지방은 미량 감소하는 경향이었는데 특히 조지방은 마늘의 첨가량이 않을수록 감소폭이 적었다. 산도는 멸치젓의 숙성 기간이 증가함에 따라 점차 감소하는 경향을 나타내었는데, 숙성 30일에 1.4~l.8g/100g의 범위었으나 숙성 90일에 급격히 감소하여 0.6~l.1g/100g까지 감소한 이후부터는 큰 변화가 없었다. 이상과 같은 실험을 종합하여 보면 저염 멸치젓 제조시 마늘을 첨가함으로서 부패취를 감소시키며 관능적으로 우수한 젓갈을 제조할 수 있었고, 이러한 특징은 멸치젓 제조시 첨가되는 마늘의 형태보다는 량에 따라 달라지게 되는데 멸치 중량에 대하여 8%, 이상 첨가하였을 때 더 효과적이었다.

The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resources. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants(Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae fructus) and we examined the effects of drink on physiological function in aorta relaxation. Thus, the effect of developed beverage on phenylephrine induced contraction of isolated rat thoracic aorta. Contractile force was measured with force displacement transducer under 1.5g loading tension. Brix, pH and titratable acidity of developed drink were 9.5%, 3.3 and 0.22%. The approximate nutritional composition of beverage was carbohydrate, 5.98%, crude protein, 0.70%, crude fat, 0.20% and crude ash, 0.20%. Developed beverage contained K(4.00 ㎎%), Na(3.68 ㎎%), Ca(2.54 ㎎%), Mg(1.60 ㎎%) and Fe(0.29㎎%). The contraction forces by injection of phenylephrine in isolated thoracic aorta were significantly low in each experimental groups compared with control groups, These results that developed drink with medicinal plants can be used as a functional material to decrease aorta contraction.
