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.

Cedrela sinensis is a Korean traditional wild herb that has special taste, aroma and red leaves. Only Korean and Chinese have been eating blanched Cedrela sinensis leaves. In this study, quality characteristics and antioxidant activity of Cedrela sinensis Jeonbyeong were compared and analyzed by pulverizing Cedrela sinensis leaves and subsequently adding by adjusting the amount of Cedrela sinensis powder. For analyzing the quality characteristics, the moisture content and pH of Jeonbyeong batter, specific volume, moisture content, color, texture profile analysis and sensory evaluations are measured. Total phenolic content showed $16.11{\pm}0.09$ mg GAE/100 g in the 12% Cedrela sinensis powder added group, which was the highest. DPPH free radical scavenging activity of Jeonbyeong indicated the highest score in the 12% Cedrela sinensis powder added group(p<0.001). While the pH(p<0.01) and moisture content(p<0.001) of batter and moisture content(p<0.01) of Jeonbyeong significantly decreased with increasing Cedrela sinensis powder content. Chromaticity measurement results of Jeonbyeong showed significantly decreased L value and b value chromaticity (p<0.001) and increased a value. Hardness significantly increased with increasing Cedrela sinensis powder content. In the sensory evaluations, 9% Cedrela sinensis powder added group ranked significantly higher than any other group in every section. From these results, we suggest that Cedrela sinensis leaves show remarkable antioxidant activity as a good ingredient for functional processed food.

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)).

This study aimed to compare the quality characteristics of developed rice Jochung (E) with those of commercial-rice Jochung (A, B, C, and D). The total soluble solid, reducing sugar, and dextrose equivalent of developed rice Jochung were $80^{\circ}Brix$, 44.53%, and 56.94%, respectively. The pH and titrable acidity were 6.25 and 0.19%, respectively. The color difference value (${\Delta}E$) of developed rice Jochung was 74.42, which was significantly lower than the other samples investigated. The light transmittance and total polyphenol contents of developed rice Jochung were 56.4%T and 108.23 mg GAE/100 g, respectively. The adhesiveness values of various commercial-rice Jochung products were 29.0~66.0 sec, while that of developed-rice Jochung was 61 sec, showing good textural properties for use in manufacturing Hangwa, a Korean traditional cookie. The electron-donating values of various rice Jochung were 20.4~50.3%, among which the developed-rice Jochung showed the highest value. The reducing powers of various rice Jochung products were 0.44~0.72, while that of the developed product was 0.72, which was significantly higher than the other values. Sensory evaluation revealed that the color scores of developed- and commercial-rice Jochung products were 6.70~6.80. Flavor scores of rice Jochung products ranged from 6.00 to 7.00. Taste and mouth feeling scores of developed-rice Jochung did not significantly differ from those of commercial Jochung products. Compared to commercial-rice Jochung products, developed-rice Jochung made with malt extract exhibited high polyphenols content. However, there were no significant differences in the overall acceptability scores between commercial-rice Jochung products and the developed product. The developed-rice Jochung analyzed in this study may be useful as a traditional sweetener for various Hangwa products as a substitute for corn syrup or Jochung.

This study was conducted to know the storage stability of Yackwa, a traditional Korean fried cookie, prepared by two different cooking methods; deep fat frying at 160$^{\circ}C$ for 8 min (DFF), and preheating Yackwa dough and then deep fat frying at 180$^{\circ}C$ for 2 min (MW/DFF). Soybean oil (SBO), hydrogenated soybean oil (HSBO) or hydrogenated palm oil (HPO) were used for frying Yackwa. Compared to Yackwa prepared by DFF, all MW/DFF Yackwa samples had low fat content and high moisture content. MW/DFF saved frying time 6 min compared with DFF. Non-hydrogenated soybean oil for frying fats was replaced with hydrogenated types of soybean oil and palm oil to improve the storage stability of Yackwa. To investigate the oxidation stability of Yackwa during the accelerated storage for 15 days at 60$^{\circ}C$, acid value, anisidine value, peroxide value and oxidation value of Yackwas were measured. Acid values of Yackwa made by MW/DFF were higher than those made by DFF through the whole storage periods, regardless of frying fats. Peroxide and anisidine values of Yackwa coated with syrup were much lower than those without syrup. MW/DFF cooking method, using hydrogenated soybean oil or hydrogenated palm oil for frying, showed lowering effects on peroxide value as well as anisidine value, resulting in improved oxidation stability of Yackwa during the storage. In sensory evaluation, the acceptability of MW/DFF Yackwa was higher than those of the commerical products. Yackwa prepared by MW/DFF cooking method using hydrogenated palm oil, showed the highest acceptability in color, taste and texture among the samples.
