  • 인천항은 한국의 주항의 하나로 원자재 수입화물을 취급하는 항만이다. 수입된 원자재 중에서 대두박등의 사료 부원료의 취급 시 강한 바람, 차량의 이동, 저장시설에서의 상하차 등에 의하여 다량의 비산먼지가 발생하여 인천항의 주된 비산먼지 오염원이 되고 있는 실정이다 (Jeon et al., 2000). 일반적으로 사료 부원료의 취급에 의하여 발생하는 비산먼지의 제진을 위하여, 사료 부원료 취급시설에 bag filter에 의한 제진시설이 사용되고 있다. (중략)

  • Effect of combined use of anti-microbial materials, such as alcohol, mustard and chitosan, or pasteurization on the quality of low salted kochujang was investigated during storage at $30^{\circ}C$ for 12 weeks. Activity of amylase decreased during storage, with lower activity in pasteurized kochujang than the other groups. Acidic protease activity increased during storage, but neutral protease activity decreased after 4 weeks. Viable cells of yeast increased during storage, but bacterial counts decreased gradually and did not show any remarkable difference among the test groups. Hunter a-values decreased as storage time increased, whereas L- and b-values decreased after 4 weeks and the degree of increase in total color difference (${\Delta}E$) was low in the supplementary ingredients added kochujang. The moisture contents and water activities decreased during storage with being lower in supplementary ingredients added groups. Titratable acidity of kochujang was decreased after 4 weeks of storage with the highest in combination of the supplementary ingredients added group. Oxidation-reduction potential was low in the supplementary ingredients added kochujang. Total sugar and reducing sugar contents of kochujang decreased during storage, with the highest contents in the supplementary ingredients added group. Ethanol content of kochujang increased during storage, whereas ethanol production was reduced in ethanol added one. Amino-nitrogen and ammonia-nitrogen contents decreased during storage with being lower in kochujang prepared with supplementary ingredients. Therefore, supplementary ingredients added kochujang would be effective for extending shelf-life of kochujang.

  • Soymilk cake (SMC) fortified with defatted soy flour was fermented by a novel Bacillus subtilis GT-D in the solid-state fermentation with chlorella, mulberry leaves or green tea as food ingredient. The fermentation of SMC resulted in higher content of tyrosine and higher activities of protease, amylase and fibrinolytic enzymes. Fermented SMC including mucilage indicated six-fold higher content of dietary fiber compared to that of non-fermented SMC. The SMC fermented without additional ingredient allowed the highest spread ratio and width of cookies. Cookies prepared without SMC showed the lowest value of spread ratio and width compared to those of fermented SMC. In addition, these cookies showed the highest hardness value of 8,975 g, and thickness value of 5.97 and slightly higher bright color. Cookies fortified with SMC fermented with chlorella or mulberry leaves showed higher sensory evaluation value. Fortification of SMC fermented without additional ingredient resulted in the highest preference in the sensory evaluation of cookies.
