Abstract
Consumer organizations usually lead the opinions of the consumers. This study was performed to investigate the perceptions and information needs of consumer organizations on food additives for the promotion of risk communication. A survey was conducted for 4 weeks in March 2012 by using a self-administered questionnaire consisting of 32 questions. Total 111 responses were collected for analysis. ``Safety (91.0%)`` was the most important factor influencing the purchase of processed food, and both ``food additives (24.3%)`` and ``environmental pollution (23.4%)`` were considered as main risk factors. The longer the career of the members had, the higher negative perceptions on food additives (p<0.01). About 70% of the respondents who had known KFDA`s researches on evaluating safety of food additives answered that researches were not enough to make sure the safety. Although lectures and other domestic organization were the main channels for getting information, ``TV`` was considered as the most suitable way for it. ``Poor risk communication (32.4%)`` was pointed out as the serious problem of government``s food safety policy. Based on these results, consumer organizations`` low level of trust on government should be overcome by continuous supply of information what they need to facilitate risk communication on food additives.

Abstract
This study investigated the quality and antioxidative properties of a Korean steamed-rice cake, Sulgidduk added with Prunus yedoensis Matsumura extract, and vitamin C. Sulgidduk was prepared by adding Prunus yedoensis Matsumura extract at 0, 0.1, 0.2, and 0.3% of rice powder. Antioxidant activities were measured by the scavenging activities of DPPH radicals, ABTS+ radicals, superoxide- radicals and the reducing power. For analyzing quality characteristics, proximate composition, color, texture profile analysis, and sensory evaluations were measured. The antioxidative effect of the Sulgidduk significantly increased as the addition level increased, compared to the original Sulgidduk (p<0.001). As the content of Prunus yedoensis Matsumura extracts increased, L-values significantly decreased while the a-value and b-value significantly increased (p<0.001). For the texture profile analysis, the control group had a significantly higher value for hardness as compared to the Prunus yedoensis Matsumura extract-added groups (p<0.05). Springiness, chewiness and adhesiveness were not significantly different among the samples. In the sensory evaluation, the samples containing 0.1% and 0.2% Prunus yedoensis Matsumura extracts obtained better results in attribute. From these results, we suggest that Prunus yedoensis Matsumura is a good ingredient for increasing the consumer acceptability and the functionality of Sulgidduk.

Abstract
In this study the physiochemical characteristics and antioxidant activity of soybean curd were prepared with saltwort (Salicornia herbacea L.). The moisture and protein of the saltwort soybean curd showed no difference among the samples. Ash and lipid were found to be the highest in the soybean curd to which 20% saltwort was added. The contents of mineral(Fe, K, Mg, Zn) were highest in the soybean curd to which 20% saltwort was added, and Ca content was high in the soybean curd to which 16% and 20% saltwort was added. DPPH (1,1-dipheny1-2-picryl-hydrazyl) radical scavenging activity is a method of measuring the antioxidant power of food; this was high in the soybean curd to which 20% saltwort was added. Adding more saltwort led to higher scavenging activity. From the above results, it could be seen that the soybean curd, which is made by adding saltwort, contributed to enhancing the functionality of antioxidant activation and product quality.

Abstract
The objective of this research was to investigate physicochemical properties of waxy sorghum flours by different milling methods (pin mill and ultra fine mill). Four different sorghum flours were used for the experiments ; PWS (pin milled whole sorghum flour), PS (pin milled sorghum flour without bran), UFWS (ultra fine milled whole sorghum flour), UFS (ultra fine milled sorghum flour without bran). The contents of crude ash and total dietary fiber were the highest in PWS. Amylose content of pin milled sorghum flour was higher than that of ultra fine milled flour. The mean particle size of pin milled flours was six times lager than ultra fine milled flours. The L values of UFS and UFWS were higher than those of PS and PWS, whereas a and b values were higher in PWS. The water binding capacity was highest in UFWS, and solubility was higher in PS and UFS. Swelling power of flours was highest in UFS. The damaged starch content was higher in PS and UFS, which means damaged starch of sorghum flours significantly affected by polishing than milling method. The pasting properties were higher in the pin milled flours. Initial pasting temperature of pin milled flour was ranging from 70.5 to 73.1℃, which are higher than ultra fine milled flour (68.6℃). The contents of total polyphenol were higher in PWS and UFWS than those of PS and UFS, there was no difference between the two milling methods. The results of this study indicate that physicochemical properties of sorghum flour were affected by milling methods as well as bran.

Abstract
Premature-green wheat is typically obtained by early harvest when culms of wheat still appear green in color, and the wheat and its food products have been considered as wellbeing foods. The pasting properties of prematured whole green wheat powder (WGWP), were analyzed with a rapid viscosity analyzer (RVA), and compared with commercial flours. The RVA values of lower peak viscosity and time, holding strength, final viscosity, as well as breakdown and setback viscosity showed that the WGWP could retard a gelatination of starch and also delay retrogradation in bakery products. WGWP with different levels of 10, 20, 30 or 50% was added into flours for preparing bakery product (bread, muffin and cookie), and their quality properties were evaluated. The addition of WGWP lead to a reduction in loaf volume of bread and muffin, and bakery products containing different levels of WGWP showed the changed internal surface structure (e.g. pore size) observed with a scanning electron microscope when compared with the control (0% WGWP). The hardness, gumminess, chewiness of bread and muffins were increased, and cohesiveness was decreased as the WGWP content increased, but the hardness of cookies was decreased. The bakery products added WGWP showed darker and more greenish and yellowish color than control (p<0.05). The sensory evaluation showed that bakeries with WGWP were scored to have more greenish taste and green color (p<0.05), and muffins and cookies with WGWP were evaluated to have more nutty and less oily taste (p<0.05).

Abstract
This study was conducted to investigate the effects of acorn (fruits of Quercus species) powder on the antioxidant activity and quality characteristics of cookies. Cookies were prepared with different amounts (0, 0.5, 1, 3 and 5% to the flour quantity) of acorn powder. The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenolic acid content in acorn powder and cookies. For analyzing quality characteristics, bulk density, pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. The moisture contents, a values, total phenolic acid content and DPPH free radical scavenging activity of cookies significantly increased with increasing acorn powder (p<0.001), while the pH of the dough, L values and b values of the cookies significantly decreased with increasing acorn powder (p<0.001). The consumer acceptability score for the 3% acorn cookie groups ranked significantly (p<0.05) higher than the other groups in overall preference, appearance, flavor, taste and color. From these results, we suggest that acorn is a good ingredient for increasing the consumer acceptability and the functionality of cookie

Abstract
The present study was conducted to evaluate the effects of Agarum cribrosum on weight change and defecation states in rats with constipation induced by loperamide. Food intake and body weight both decreased in the 5% Agarum cribrosum and loperamide-treated group (SD5) and 10% Agarum cribrosum and loperamide-treated group (SD10), whereas fecal water contents increased by 1.6 and 2.1-fold in the SD5 and SD10 groups, respectively. The concentrations of total-cholesterol, HDL-cholesterol and triglyceride in the sera of the SD5 and SD10 groups were lower than those in the control (C) group. However, the biochemical parameters, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), and glucose levels, were not affected by the level of Agarum cribrosum. In addition, the concentrations of total-cholesterol and triglyceride in the livers of the SD5 and SD10 groups were also lower than those in the control group. The results of the present study demonstrated that Agarum cribrosum might ameliorate constipation symptoms, and lower lipid concentrations in the blood and liver.
