매실 리큐르 제조 후 부산물로 폐기되는 폐매실을 식자원으로서의 이용가능성의 검토하기 위해 폐매실의 첨가가 김치의 발효에 미치는 영향을 검토하였다. 매실 리큐르 제조후 부산물로 나오는 매실 분쇄 과육을 절임배추 무게에 10%, 20%를 첨가하여 에서 25일간 발효 중 젖산균수, 총균수는 대조구에 비해 낮게 나타났으며, pH와 산도는 PLB 20% 첨가구는 발효 기간 동안 완만한 변화를 나타내어 매실 첨가량이 증가할수록 김치 발효는 지연되는 경향을

Quality changes of kimchi added with 10 or 20% Prunus mume liqueur byproduct (PLB), obtained after producing Prunus mume liqueur. during fermentation at for 25 days were investigated. The pH and titrtable acidity in 20% PLB added kimchi were changed more gradually during fermentation for 25 days compared to control. Total bacteria and lactic acid bacteria counts in kimchi added with 20% PLB were lower than those of control during fermentation for 15 days. Kimchi fermentation was delayed about 10 days with 20% PLB. L and a values of kimchi added with PLB decreased but b value increased with increasing the concentration of PLB. In the sensory evaluation of kimchi fermented for 10 days, the texture score of PLB added kimchi was higher than that of control, and increased with increasing the concentration of PLB. There were no significant differences (p < 0.05) in overall acceptability among control kimchi and PLB added kimchi.
