연근즙 첨가수준에 따라 백김치를 제조한 후 에서 4주간 저장하면서 숙성 중의 이화학적, 관능적 특성을 조사하였다. 연근즙의 첨가수준이 증가할수록 pH는 감소, 산도는 반대로 증가하는 경향을 보였고 숙성기간 중에도 같은 경향을 보였다. 탁도는 첨가수준이 증가할수록 증가함을 볼 수 있었으며, 숙성 2주까지는 대조군의 비해 첨가군의 경우 탁도가 증가하는 경향을 보였으나 숙성 3주, 4주에서는 약간 더 감소하는 경향을 보였다. 색도 L 값과 a 값은 연
The physicochemical and sensory properties of Baik-Kimchi supplemented with Lotus root juice were periodically examined during fermentation at over 4 weeks. The pH decreased and acidity gradually increased during fermentation. Turbidity also increased as the level of added Lotus root juice increased, with a gradual rise being evident over 2 weeks with a subsequent decrease to the 4-weekpoint of fermentation. The L- and a-values decreased as the amount of added Lotus root juice increased, whereas the b value increased. The reducing sugar content increased when Baik-Kimchi was supplemented with 3% or 6% (both w/v) Lotus root juice, but decreased when Baik-Kimchi was supplemented with 9% or 12% (both w/v) root juice. Reducing sugar content decreased as fermentation continued. The vitamin C content was higher in supplemented samples, than in the control during fermentation. The hardness of Baik-Kimchi supplemented with Lotus root juice decreased with increasing fermentation time. By sensory evaluation, addition of 6%(w/v) root juice yielded a product superior in color, smell, crispness, and overall acceptability compared with control. In conclusion, optimal Baik-Kimchi fermentation should include addition of 6% (w/v) Lotus root juice.
