초록

본 연구에서는 보다 간단하고 신속한 공정으로 생산량 증가 및 비용절감을 도모할 수 있는 한국형 복분자 발사믹 식초 생산공정 개발을 위한 증류과정 도입가능성을 알아보았다. 증류과정을 통해 생산된 농축식초분획의 발사믹식초로서의 활용가능성과 증류식초분획의 증류식초로서의 활용가능성을 파악하기 위해 증류과정에서 얻어진 식초 분획을 대상으로 총산도, 산도pH 및 비중을 측정하였다. 총산도가 서로 다른 4종류의 식초(총산도; 4.42, 4.84, 5.61, 및 6.35)를 60%까지 증류했을 때 농축식초분획의 총산도는 증류 전 식초보다 평균 38.1% 증가하였다. 특히 최종 농축식초분획의 총산도 및 산도pH는 발사믹식초와 유사한 것으로 나타났다. 한편 증류식초분획 역시 총산도가 증가하여 최종 분획의 총산도는 각각 4.41%, 4.95%, 5.88%, 및 6.72% 이었으며 증류식초로 활용이 가능할 것으로 판단되었다. 본 연구에서는 증류공정을 통해 식초를 효과적으로 농축시킬 수 있을 뿐 만 아니라 동시에 증류식초를 생산할 수 있음을 확인하였다. 그러나 식초분획별로 유기산 함량 및 항산화활성 측정 등 추가적인 생화학적 특성 분석이 이루어져야 증류공정 도입여부를 결정할 수 있을 것으로 사료된다.

In our study, we evaluated possibility of distillation process introduction for Korean Rubus coreanus balsamic vinegar production development, has a less complicated and more rapid process leading to higher production volumes and cost savings. In order to investigate the applicability of concentrated vinegar fraction (CVF) and distilled vinegar fraction (DVF) obtained from the distillation process as balsamic and distillation vinegar, acidity, pH, and specific gravity (S.G.) were measured for the vinegar fraction obtained from the distillation process. The acidity of final CVF (60% of initial volume) obtained 4 types of vinegar (acidity; 4.42, 4.84, 5.61, and 6.35) were increased mean 38.1%, compared to initial acidities. Especially, acidity and pH of the final CVF was similar to balsamic vinegar. In addition, acidity of DVF also increased and it of the final fraction was 4.41%, 4.95%, 5.88%, and 6.72%, respectively. And it was suggested that the final DVF could be used as distilled vinegar. In this study, it was confirmed that vinegar can be effectively concentrated through the distillation process, and distilled vinegar can be produced at the same time. However, it is thought that the introduction of the distillation process can be decided only after additional biochemical characteristics such as organic acid content and antioxidant activity measurement for each vinegar fraction are analyzed.
