포장김치의 표면처리가 김치의 pH, 산도, 총균수, 젖산균수, 표면갈변도 및 이미, 이취발생에 미치는 영향을 조사하였다. 표면처리는 포장김치표면에 70% 에탄올을 1회 분무한것과 김치표면에 PE-film(두께 0.04mm)을 부착한 것으로 나누어 행하였으며, 1에서 저장하였다. 무처리와 에탄올을 분무한 경우는 저장 15째에 pH가 4.0수준에 도달하였으나 PE-film을 처리한 경우는 21일째까지도 pH가 4.0 이상을 유지하였다. 산도의 경우도

This they was conducted to investigate the surface treated effect of Packaged kimchi on the PH, acidity, total microbe, number of lactic acid bacteria, browning and formation of off-flavor during storage at 10. Kimchi was treated with 70% ethanol(1 time spraying) and attachment of polyethylene film(PE) on the surface of packaged kimchi and stored at 10. pH of the control and ethanol treated kimchi stored for 15 days was decreased to 4.0 level but, the pH of PE-treated kimchi maintained over pH 4.0 until 21 days of storage. The aridity was the same tendency as the pH, which showed delaying of fermentation by PE treatment. Total microbe of PE treated kimchi was lower and number of lactic acid bacteria was higher than those of control and ethanol treated products, respectively. Degree of browning and off-flavor of control and ethanol treated kimchi increased from 13 days of storage, but the degrees of the PE-treated kimchi was lower during all storage periods.
