BACKGROUND/OBJECTIVES: Owing to health concerns related to the consumption of traditional snacks high in sugars and fats, much effort has been made to develop functional snacks with low calorie content. In this study, a new recipe for Korean rice cookie, dasik, was developed and its antioxidative, lipid-lowering, and anti-inflammatory effects and related mechanisms were elucidated. The effects were compared with those of traditional rice cake dasik (RCD), the lipid-lowering effect of which is greater than that of traditional western-style cookies. MATERIALS/METHODS: Ginseng-added brown rice dasik (GBRD) was prepared with brown rice flour, fructooligosaccharide, red ginseng extract, and propolis. Mice were grouped (n = 7 per group) into those fed a normal AIN-76 diet, a high-fat diet (HFD), and HFD supplemented with RCD or GBRD. Dasik in the HFD accounted for 7% of the total calories. The lipid, reactive oxygen species, and peroxynitrite levels, and degree of lipid peroxidation in the plasma or liver were determined. The expression levels of proteins involved in lipid metabolism and inflammation, and those of antioxidant enzymes were determined by western blot analysis. RESULTS: The plasma and hepatic total cholesterol concentrations in the GBRD group were significantly decreased via downregulation of sterol regulatory element-binding protein-2 and 3-hydroxy-3-methylglutaryl-CoA reductase (P < 0.05). The hepatic peroxynitrite level was significantly lower, whereas glutathione was higher, in the GBRD group than in the RCD group. Among the antioxidant enzymes, catalase (CAT) and glutathione peroxidase (GPx) were significantly upregulated in the GBRD group (P < 0.05). In addition, nuclear factor-kappaB (NF-${\kappa}B$) expression in the GBRD group was significantly lower than that in the RCD group. CONCLUSIONS: GBRD decreases the plasma and hepatic cholesterol levels by downregulating cholesterol synthesis. This new dasik recipe also improves the antioxidative and anti-inflammatory status in HFD-fed mice via CAT and GPx upregulation and NF-${\kappa}B$ downregulation. These effects were significantly higher than those of RCD.

참죽나물은 맛과 향 및 붉은 색이 조화를 이루는 귀한 산채 중의 하나로 우리나라와 중국에서만 이른 봄에 참죽나무 순을 데쳐서 나물로 먹었던 전통식품 중의 하나이다(Kim et al. 2012). 본 연구는 전통 산채인 참죽나무 잎을 분말화한 후 첨가량을 달리하여 전병반죽에 첨가하여 total phenolic content, DPPH free radical 소거활성을 측정하였으며 참죽 전병의 품질특성을 비교분석하기 위해 반죽의 수분 및 pH, 전병의 비중, 수분, 색도, 경도, 관능평가를 실시하였다. 이를 통해 참죽나무 잎의 저장성과 가공방법을 연구하고 전병에 첨가하여 기호 및 영양학적 가치를 높이고자 하였다. 참죽 전병의 total phenolic content는 참죽 분말 12%를 첨가한 첨가군이 $161.1{\pm}0.09$ mg GAE/100 g로 가장 높았다. DPPH free radical 소거활성은 $1000{\mu}g/m{\ell}$ 수준에서 12% 첨가군이 가장 높은 활성을 보였다. 반면 반죽의 pH와 수분함량은 참죽 분말이 증가함에 따라 감소하였으며, 전병의 수분함량 또한 감소하였다. 전병의 색도는 L값과 b값은 참죽 분말 첨가량이 증가할수록 낮아지고, a값은 높아지는 유의적인 차이를 나타냈으며, 경도는 시료 첨가에 따라 다소 증가하는 경향을 나타내었다. 관능검사에서는 9% 첨가군이 모든 항목에서 가장 높은 선호도를 보였다. 이러한 결과들로 미루어 보아 참죽 분말은 뛰어난 항산화능을 보이고 있으며 가공식품의 기능성 재료로 충분한 가치가 있음을 확인할 수 있었다.

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 principal objective of this study was to assess the quality characteristics of Sprouted Brown Rice Dasik(SBRD) manufactured with various addition levels of honey and Yujacheong(Yuja syrup and Yuja sarcocarp) in accordance with the traditional method for the preparation of Korean Dasik(a kind of cookie). The nutritional components, color value, physical tests, volatile compounds, and sensory evaluation of SBRD to which Yujacheong was added were conducted. The results were summarized as follows. In SBRD to which Yujacheong had been added, the moisture contents and crude fat content did not differ significantly among the sample groups, and the contents of crude protein and crude ash increased with increasing additions of Yuja syrup and Yuja sarcocarp. The pH(p<0.001) and sweetness(p<0.001) were significantly higher in sample D1 than in samples D2 and D4. The L color value was highest in D2, the a value was highest in D3, and the b value was highest in sample D2. The texture property analysis showed that the cohesiveness, springiness, gumminess, and chewiness of SBRD to which Yujacheong was added were all significantly higher compared to sample D1. According to the results of our volatile analysis, the D1 and other experimental groups evidenced different flavors and antibacterial compositions. According to the results of our sensory evaluation, the appearance of the D1 sample was superior to the other samples. However, flavor, taste, texture, and overall preference were higher in the samples to which Yuja syrup and Yuja sarcocarp were added. These results indicate that SBRD to which Yujacheong was added, and particularly those to which Yuja syrup was added, is superior to Dasik prepared with honey in terms of flavor and taste, and this method will improve the flavor and preparation time, due to its lower pH.

Yetgangjeong is a traditional Korean rice cookie which used rice syrup (Chocheong) to bind fried rice grains. Brown waxy rice and binders prepared using different sugar types and end heating temperatures were assessed to improve the textural properties and functionality and to promote global consumption. Binder was made by mixing different ratios of starch syrup, rice syrup, honey, sugar, and trehalose, and the binder mixture was heated up to a temperature of $100^{\circ}C$ or $105^{\circ}C$. Specific electrical conductivity of binder containing ST (starch syrup and trehalose) showed the lowest values (9.51 and 9.77), and binders containing the rice syrup showed increased values for specific electrical conductivity. The fructose content was higher in the binder mixture containing C (starch syrup and sugar) than in the binder mixture containing ST, but it did not affect the end temperature. Viscosity of the binder was 123.90-175.20 cP and the binder showed higher viscosity at the end heating temperature (EHT) of $100^{\circ}C$ compared at EHT of $105^{\circ}C$. The fracturability of brown rice yetgangjeong prepared using different sugar types was higher at EHT of $100^{\circ}C$ than at that of $105^{\circ}C$ and it was reduced with an increase in the rice syrup content. However, the hardness of yetgangjeong was lower at $100^{\circ}C$, unlike fracturability. With respect to sensory evaluation, its moistness and stickiness decreased, but the crunchiness increased with addition of trehalose instead of sucrose. The overall eating quality score of yetgangjeong was higher at EHT of $105^{\circ}C$ than at that of $100^{\circ}C$ in every experiment and the highest score was found for SHT (starch syrup, honey and trehalose) with 20% rice syrup at EHT of $105^{\circ}C$ (20%RSHT105 (starch syrup, honey, and trehalose containing 20% rice syrup)).

전통 약과 반죽을 microwave 열처리로 전처리한 후 튀김기에서 튀기는 절충 방법(MW/DFF)을 도입하여 튀김시간 단축에 의한 튀김유 흡수 감소와 불량률 감소를 기하고 저열량의 저장성이 향상된 약과를 개발하고자 약과의 튀김유로 널리 사용되고 있는 대두유를 경화유인 대두 경화유와 팜경화유로 대체하여 6$0^{\circ}C$에서 7, 11, 15일간 약과를 저장하여 약과의 지방 가수분해 및 지방산화 변화를 화학적 측정을 통하여 지방의 산패과정을 살펴보고 튀김유에 따른 약과의 기호도를 관능 검사를 통하여 비교하였다. MW/DFF 방법에 의하여 튀김시간이 DFF 조리 방법의 8분에서 2분으로 단축되었고 약과의 지방 함량은 10% 감소하였으며 수분 함량은 6% 정도 증가하였다. 저장 기간 동안의 산가는 조리 방법 DFF 보다 MW/DFF가 높게 나타났고 MW/DFF에서 집청전 보다 집청후가 현저히 증가되어 지방의 가수분해는 약과의 수분 함량 상승에 기인함을 알 수 있었다. peroxide value는 튀김시간이 긴 DFF방법의 대두유(SBO)를 사용한 약과에서 저장 기간 동안 현저히 증가되었고 반면에 튀김유로 대두 경화유(HSBO)와 팜경화유(HPO)를 사용 한 경우 조리 방법에 관계없이 매우 완만한 변화를 나타내어 산화 안정성이 매우 높은 것으로 나타났다. 2차 산화생성물값을 나타내는 anisidine value는 SBO에 튀긴 집청전의 DFF 약과는 저장초기부터 급격히 증가하였으나 상대적으로 튀김시간이 짧은 MW/DFF 약과에서는 저장동안 별 변화가 없었고 집청후의 약과에서는 조리방법의 튀김시간에 관계없이 변화가 거의 나타나지 않았다. 종합적인 산화정도를 나타내는 oxidation value는 DFF의 약과 보다 MW/DFF의 약과에서 저장 기간 동안 낮게 나타났으며, 집청전보다 집청후가 더욱 안정되어 튀김시간의 단축, 경화유 사용 및 집청이 약과 지방의 산패 방지에 효과가 있음을 확인하였다. 기호도 검사에서 실험 약과가 시중 약과 보다 우수하였고 MW/DFF의 팜경화유(HPO)로 튀긴 약과의 기호도가 가장 좋게 나타나 약과의 튀김유로 적당함을 알 수 있었다.
