Abstract
|
|
|
1) Many bacterial strains identified as Bacillus megeterium, Bacillus subtilis and Bacillus licheniformis were aboundantly found in summer jokal kimchi, but the most dominant strains in summer kimchi were Lactobacillus plantarum and Loctobacllus buchneri.
2) Bacillus groups found in kimchi were sensitive in a low concentration of AF-2, but groups of lactic acid bacteria were resistant to a high concentration of AF-2.
3) Allowable concentration of AF-2 in Korean kimchi is less than 10 p.p.m.
4) AF-2 was not suitable for the juicy kimchi as a preservative because the color of juicy kimchi was somewhat changed into orange red when 10 p.p.m. of AF-2 was added.
5) High concentration of AF-2 leads the hetero-fermentation of kimchi bacteria to the homofermentation.
6) Microflora of kimchi was influenced even in the concentration of 10 p.p.m. but it was impossible to check the acidification of kimchi in summer with 50 p.p.m. concentration of AF-2.
7) About 25% of AF-2 was consumed in kimchi fermentation for day at 23℃-25℃.
