  • This study was carried out in order to investigate the possibility of frozen rice batter for the manufacturing of Jeung-pyun. Despite of its unique taste and texture, Jeung-pyun is not consumed much because it needs long time to make. The physicochemical, sensory, rheological and surface characteristics of Jeung-pyun were analyzed to develop the easy manufacture method. The storage condition of rice batter was used at -2$0^{\circ}C$ up to 4 weeks. Statistical data analysis was completed using a SAS program. The results are summarized as follow: The pH brix% and sugar content of all samples which added low-temperature tolerance raw yeast or regular raw yeast decreased during the fermentation. Kind of yeast did not influence on the moisture content of the Jeung-pyun batter. Specific volume and carbon dioxide evolution of Jeung-pyun batter were highest when the rice batter was frozen for 1 week regardless of the kind of yeast. Overall quality of frozen batter of Jeung-pyim at -2$0^{\circ}C$ for 4 weeks had the highest score among different samples. As the test results of mechanical characteristics, cohesiveness, gumminess, brittleness, hardness and springiness did not show any significant differences statistically. The result clearly suggests that freezing the rice batter is a possibile way to manufacture Jeung-pyun.

  • The integrated permit system is applied to class 1 and 2 atmospheric and water pollutant discharge facilities in 19 sectors. The fertilizer sector should receive a permit for a period of four years, from 2019 to 2023. The purpose of this study is to investigate the differences between the Korean Best Available Techniques (BAT) reference document (K-BREF) and the European Union BAT reference document (EU-BREF) in terms of the process and emission characteristics of fertilizer manufacture. K-BREF is written by focusing on products, whereas EU-BREF is produced on focusing on manufacture process. There are five types of BATs(best available techniques economically achievable) in Korea. These BATs selected mainly to recover and reuse raw meterials and save energy. The number of BATs and BAT-AELs(BAT associated emission level) in K-BREF is smaller than that in EU-BREF. We suggest that BATs and those environmental management parameters in Korea need to further reflect the emission characteristics in the fertilizer sector.

  • By surveying the 70 composting plants in Gyeonggi Province, the total commercial production of livestock faeces composts (LFCs) in 2008 was estimated to be about 480,000 Mg year-1 and they were manufactured mainly by using both mechanical mixer and bottom air blower. LFCs were composed mainly of chicken faeces 29.2%, pig+chicken faeces 23.1%, pig faeces 20.0%, livestock faeces+oil cake 12.3%, pig+chicken+cattle faeces 10.8% and pig+cattle faeces 4.6%. On the basis of the current official standard which was revised on March 2010, 11 composts out of surveyed 76 ones did not meet the LFCs quality standard (LQS) due to inadequate content of water (5), OM/N (1), NaCl (2) and Zn (3). The OM/N declined by adding chicken faeces and oil cake, while Ca content increased by the addition of chicken faeces and NaCl increased by adding cattle faeces.

  • Objective: The objective of this study was to evaluate quality characteristics of reduced-salt pork sausage (PS) using pre-rigor muscle compared to those of regular-salt PS. In addition, effects of freezing on sausage batter with different temperatures (-30℃ vs -70℃) on quality characteristics of both sausage batter and cooked sausages during frozen storage were observed. Methods: Pre-rigor and post-rigor pork hams were used to manufacture low-fat sausages. Sausages using post-rigor (Post) muscle were manufactured at a salt level of 1.5%, whereas those with pre-rigor (Pre) muscle were processed at salt level of 1.0%. After these muscles were made at two salt levels (1.5% salt, Post-rigor; 1.0% salt, Pre-rigor), Sausage batters were stored at two frozen temperatures (-30℃ vs -70℃). During storage for 12 wks, they were measured for physicochemical and textural properties every 4 wks up to 12 wks. Results: pH values and temperatures of sausage batter of pre-rigor muscle were higher than those of post-rigor muscle regardless of the frozen temperature. The lightness and yellowness values of batter at the initial storage were the highest during storage. For PS, there were no differences in most parameters measured among all treatments. However, expressible moisture values (%) of Pre-30 and Pre-70 were lower than those of Post-30 (p<0.05). Conclusion: Regardless of frozen temperature during storage, quality characteristics of pre-rigor PS with salt level of 1.0% salt were similar to those of post-rigor PS with salt level of 1.5%. By using the pre-rigor muscle, salt content could be reduced by one third of the regular-salt level (1.5%) of post-rigor muscle.

  • Oddi is a mulberry (Morus alba L) fruit which has antiinflammatory and antioxidative effects. This study was carried out to investigate the quality characteristics of Oddi-Pyun which was manufactured with various addition levels (0, 0.5, 1, 2, 4%) of Oddi extract according to the traditional Korean Kwaypun (a kind of jelly) methodology. Oddi-Pyun was made with various levels of Oddi extract, mungbean starch (9%) and sugar (30%). To establish the additional amount of mulberry fruit extract, sensory evaluation and physical test were carried out. From the results of sensory evaluation, the 2% of Oddi-Pyun was judged as the best in terms of color, flavor, hardness and elasticity. According to texture characteristics (hardness, adhesiveness, springiness, gumminess and chewiness), 1.0% and 2.0% of Oddi-Pyun were judged as the best. The contents of Ca (69.50, 74.75, 84.25, 100.60, 183.55ppm), Mg(27.37, 29.38, 34.20, 46.73, 97.45ppm) and Fe (320.23, 572.45, 680.50, 725.95, 906.50ppb) increased with increasing Oddi extract. Therefore, the optimal added amount of extract for the manufacture of Oddi-Pyun was proposed as 2% to the total weight. It was concluded that this Oddi-Pyun would be helpful to improve the health status of rheumatics and patients with similar diseases.

  • This study was conducted to investigate quality characteristics of Aster scaber to increase the value of functional food resources. To examine quality characteristics of Aster scaber, various factors such as color, texture, fiber, minerals, tannin, crude proteins, crude lipids and sensory quality were determined using physiochemical methods. The contents of dietary fiber were 0.68 g in each 100 g of Aster scaber (freeze drying base). In mineral contents, iron was the highest value in Aster scaber (freeze drying base). The contents of tannin were 35.6 ppm of Aster scaber (fresh base). Aster scaber was shown significant difference in tannin from freeze drying leaf. From the results of sensory evaluation, the age of 30's and 40's showed a better acceptability in blanching. Functional healthy drinks were made from extracts of Aster scaber for relieving thirst and promoting health. The recipe of drinks were decided to establish manufacture condition through the sensory evaluation, color, flavor, taste, and overall acceptability. The shelf-life was established in 18 months through quality was analyzed such as soluble solids, optical density 480, pH, acidity and microorganisms.
