- W1998182218 abstract "본 연구는 내냉성 미생물이 Gouda cheese의 지방 성분에 미치는 영향을 알아보기 위해 수행하였다. 지방분해 효소 활성이 가장 높은 내냉성미생물인 Acinetobacter genomospecies 10을 원유에 접종하여 3일과 6일 냉장 보관 후 제조한 Gouda cheese는 숙성 6주 경과후 총고형분과 지방 성분은 대조군에 비해 각각 유의적으로 증가하였다(p<0.05). 접종 3일후 원유로 제조한 Gouda cheese는 대조군에 비해 SCFFA는 1.35배, MCFFA는 1.42배, LCFFA는 1.44배로 유의적으로 증가하였다(p<0.05). 또한 총유리지방산 함량은 대조군에 비해 1.68배로 유의적으로 증가하였다(p<0.05). 접종 6일 후 원유로 제조한 Gouda cheese는 대조군에 비해 SCFFA는 1.45배, MCFFA는 1.28배, LCFFA는 1.38배로 유의적으로 증가하였다(p<0.05). 또한 총유리지방산 함량은 대조군에 비해 1.34배로 유의적으로 증가하였다(p<0.05). 내냉성미생물이 생산하는 지방분해효소에 의해 얻어진 지나친 유리지방산은 이취를 유발할 수 있어, 유제품의 품질을 저하시킬 수 있음을 시사한다. The presence of psychrotrophic bacteria downgrades the quality of dairy products. This study evaluated the effect of lipolytic psychrotrophic bacteria on the chemical properties of Gouda cheese made from raw milk experimentally inoculated with a psychrotrophic bacterium (Acinetobacter genomospecies 10). Raw milk experimentally inoculated with Acinetobacter genomospecies 10 and refrigerated at <TEX>$4^{circ}C$</TEX> for 3 or 6 days produced a 6-week ripened Gouda cheese with a significant decrease in total solids (p<0.05) or an increased fat content (p<0.05), respectively. Raw milk inoculated with Acinetobacter genomospecies 10 and refrigerated for 3 days had higher (p<0.05) SCFFA (1.35 times), MCFFA (1.42 times), and LCFFA (1.44 times) than the control 6-week ripened Gouda cheese. The cheese manufactured from the inoculated and refrigerated raw milk had higher (p<0.05) total free fatty acids (1.68 times) compared with the control. Raw milk inoculated with Acinetobacter genomospecies 10 and refrigerated for 6 days had increased SCFFA (1.45 times), MCFFA (1.28 times), and LCFFA (1.38 times) compared with the control 6-weeks ripened Gouda cheese. The 6-week ripened Gouda cheese manufactured from this inoculated milk had higher (p<0.05) total free fatty acids (1.34 times) compared with the control. The results indicated that the production of excessive free fatty acids in dairy products by psychrotrophic bacteria can be critical in predisposing dairy products to off-flavors and in turn degrading their quality." @default.
